Asbestos Brake Pads and Vehicle Parts: What Every Fleet and Workshop Manager Must Know
Older vehicles can harbour a hidden danger that most people never consider until someone is already seriously ill. Asbestos brake pads and vehicle parts remain a genuine occupational health hazard in workshops, garages, and fleet maintenance facilities across the UK — and the consequences of ignoring that risk can be severe, irreversible, and in many cases fatal.
Whether you manage a commercial fleet, oversee a garage, or work on classic cars, understanding where asbestos hides in vehicles and how to control exposure is both a legal and moral obligation. This is not a historical curiosity — it is an active, ongoing risk affecting real workers right now.
Which Vehicle Parts Commonly Contain Asbestos?
Asbestos was widely used in automotive manufacturing because it handles extreme heat and heavy wear exceptionally well. Those same properties that made it attractive to manufacturers meant it was embedded deep into friction materials, insulation, and sealing components across decades of vehicle production.
Any vehicle built before the mid-1990s should be treated as potentially containing asbestos-containing materials (ACMs) until proven otherwise. The older the vehicle, the higher the likelihood.
Brake Pads and Brake Linings
Asbestos brake pads and vehicle parts linked to braking systems are the most well-known source of exposure. Drum brakes and disc brakes manufactured before the 1990s commonly contained chrysotile (white asbestos) at concentrations of roughly 35% to 60% of the material by weight — levels that made them highly effective under thermal stress and highly dangerous when disturbed.
Brake dust generated during cleaning, grinding, or replacement work can contain significant concentrations of asbestos fibres. Routine tasks such as blowing out a brake drum or dry-brushing a rotor can send microscopic fibres airborne across an entire workshop bay within seconds.
It is also worth noting that while the UK and EU banned asbestos in vehicle parts, aftermarket components sourced from certain overseas markets may still contain asbestos. Any older stock in a parts inventory should be treated with caution until professionally tested.
Clutch Linings and Engine Gaskets
Clutch linings in manual gearboxes and automatic transmissions frequently contained chrysotile asbestos, chosen for its ability to withstand intense heat generated during gear changes. Engine gaskets — the seals between metal components throughout the engine — also commonly incorporated asbestos fibres for the same reason.
Mechanics who spent careers working on clutch and brake components have shown evidence of pleural plaques and asbestosis even after accounting for age, smoking history, and other health factors. Any facility carrying out this type of work on older vehicles must have robust controls in place before work begins.
Insulation, Heat Shields, and Other Hidden Sources
Asbestos appeared in a surprisingly wide range of automotive components beyond braking systems. Insulation was used in floorboards, firewalls, bonnet liners, and transport compartments to resist heat and slow flame spread. Some air conditioning housings contained asbestos at significant concentrations by weight.
Other components known to have contained asbestos include:
- Heat shields around exhaust systems and mufflers
- Muffler repair compounds
- Electrical wire insulation and looms
- Certain spark plug boot materials
- Body fillers and asbestos cement compounds
- Soundproofing and underbody mats
- Decorative stripe decals and paint undercoats
- Packing materials, valves, and heat seals
Woven asbestos backing has been found beneath carpets and inside bonnet liners of older vehicles. If you manage a site where older vehicles are stored, repaired, or broken for parts, a professional survey is the only reliable way to identify what you are dealing with.
The Three Types of Asbestos Found in Vehicle Parts
Not all asbestos is the same. Understanding which type may be present helps determine the level of risk and the appropriate response.
White Asbestos (Chrysotile)
Chrysotile was by far the most common type found in vehicle friction materials, including brake pads, brake linings, clutch linings, and engine gaskets. Its curly fibre structure made it easier to weave into composite materials, and it accounted for nearly all asbestos used in the UK automotive sector until stricter regulations came into force.
Brown Asbestos (Amosite)
Amosite appeared in some automotive insulation components and certain gaskets and exhaust parts. Its fibres are straight and brittle, making them easier to inhale deeply into lung tissue. Amosite carries a higher association with respiratory cancers than chrysotile.
Blue Asbestos (Crocidolite)
Crocidolite is the most hazardous of the three types. Even low-level exposure is associated with a significantly elevated risk of mesothelioma. It is less commonly found in vehicle parts than chrysotile, but its presence cannot be ruled out without professional testing.
All three types break down into microscopic fibres that become airborne during disturbance and can remain suspended for extended periods. Do not attempt to identify asbestos by appearance alone — only a qualified surveyor using accredited laboratory analysis can confirm which type is present and at what concentration.
Health Risks: What Asbestos Exposure from Vehicle Parts Can Cause
The health consequences of repeated exposure to asbestos fibres from brake pads and other vehicle components are severe and, in many cases, fatal. Diseases caused by asbestos exposure typically take decades to develop, which means someone working in a garage in the 1980s may only now be receiving a diagnosis.
Mesothelioma and Lung Cancer
Pleural mesothelioma — a cancer of the lining surrounding the lungs — is almost exclusively caused by asbestos exposure. Peritoneal mesothelioma, which affects the lining of the abdomen, has also been linked to occupational exposure from friction materials including brake pads and clutch linings. There is no cure, and survival rates remain poor.
Lung cancer risk is also elevated in workers with long-term exposure to asbestos dust. The combination of asbestos exposure and smoking significantly multiplies that risk. Legal cases have produced substantial awards for workers and families who can demonstrate that brake or clutch work contributed to their diagnosis — a clear reminder that this is not a theoretical risk.
Asbestosis
Asbestosis is a chronic, progressive scarring of lung tissue caused by inhaling asbestos fibres over time. Symptoms include breathlessness, a persistent cough, and reduced lung function. There is no cure; management focuses on slowing progression and relieving symptoms.
High-resolution CT scanning detects these changes more reliably than standard chest X-rays, meaning some workers may not receive a diagnosis until significant damage has already occurred.
Pleural Plaques and Other Respiratory Conditions
Pleural plaques are areas of thickened tissue on the lining of the lungs. They are a marker of past asbestos exposure and, while not cancerous themselves, their presence indicates that a person has been exposed to levels of asbestos sufficient to cause physical changes to lung tissue. Their presence may indicate elevated risk of more serious conditions developing over time.
How Exposure Happens: Mechanics, DIY Repairs, and Secondary Risks
Understanding how asbestos fibres are released during vehicle work is essential for putting the right controls in place. Exposure does not only happen in professional garages — DIY mechanics working on older vehicles at home face the same risks, often without any protective equipment at all.
Brake Dust as a Primary Exposure Route
Brake dust is one of the most significant sources of asbestos fibre exposure in automotive settings. Disturbing brake drums, shoes, or linings — even through routine inspection — sends dust into the air and deposits fibres on surrounding surfaces, clothing, and tools.
Common tasks that generate dangerous brake dust include:
- Blowing out brake drums with compressed air
- Dry-brushing brake components during inspection
- Grinding or machining brake linings
- Removing old brake shoes or pads without wet suppression
- Cleaning brake assemblies with dry cloths or rags
Each of these actions can generate airborne fibres that remain suspended long enough to be inhaled by anyone in the vicinity — not just the mechanic carrying out the work.
Secondary and Domestic Exposure
Asbestos fibres do not stay in the workshop. They cling to clothing, hair, and skin, and can be carried home on workwear. Family members of mechanics have developed mesothelioma through secondary exposure — simply from living with someone who worked with asbestos-containing materials.
This is sometimes called para-occupational exposure, and it underlines the importance of proper decontamination procedures and controlled laundering of work clothing.
Risks During Clutch and Gasket Repairs
Beyond brake work, clutch repairs, gasket replacements, and work near insulation components all carry exposure risk. The HSE’s guidance under the Control of Asbestos Regulations sets out clear requirements for managing this risk in workplaces, including:
- Using enclosed HEPA-filter vacuum systems or low-pressure wet methods for cleaning — never dry brushing or compressed air
- For facilities carrying out more than five brake or clutch jobs per week, wet methods are the minimum standard
- High-volume garages should consider negative-pressure enclosures with HEPA filtration
- Providing tight-fitting respirators with P3 filters, disposable coveralls, and gloves
- Isolating dusty work areas and controlling access
- Bagging all contaminated rags and suspected asbestos waste for disposal by a licensed handler
- Never washing contaminated workwear in standard laundry — use controlled laundering or disposable coveralls
Employers have a legal duty to protect workers from asbestos exposure. Failing to do so carries significant legal and financial consequences, in addition to the human cost.
Legal Obligations for Workshops and Fleet Managers in the UK
The Control of Asbestos Regulations places clear duties on employers and those in control of premises. If your facility handles older vehicles or maintains a fleet that includes pre-1990s models, you must assess the risk of asbestos exposure and put appropriate controls in place.
HSG264 — the HSE’s guidance on asbestos surveys — sets out the types of survey required depending on the nature of the work. An management survey identifies and assesses ACMs that could be disturbed during normal occupation and day-to-day maintenance. It is the baseline requirement for most workplaces, including garages and fleet maintenance facilities.
Where significant refurbishment or demolition work is planned — including work to vehicle inspection pits, workshop floors, and areas where vehicles are dismantled — a demolition survey is required before any such work begins. This more intrusive type of survey ensures that all ACMs are identified before they can be disturbed.
Failing to commission the appropriate survey before work begins is not just a regulatory breach — it can result in uncontrolled fibre release, worker exposure, and significant liability for the duty holder.
Practical Steps for Garage Owners and Fleet Managers
If you manage a workshop, garage, or vehicle maintenance facility, the following steps will help you meet your legal obligations and protect your workers.
- Assume ACMs are present in any vehicle or building component dating from before the mid-1990s until professional testing confirms otherwise.
- Commission a professional asbestos survey of your premises before any refurbishment, maintenance, or demolition work that could disturb the building fabric or stored materials.
- Maintain an asbestos register for your premises and ensure it is accessible to anyone who may disturb ACMs during their work.
- Train all relevant staff on asbestos awareness, including how to recognise potentially affected components and what to do if they suspect disturbance has occurred.
- Never dry-clean or blow out brake components on older vehicles. Use wet methods or HEPA-filtered vacuum systems only.
- Source replacement parts carefully and verify that all new components are asbestos-free, particularly if sourcing from non-EU suppliers.
- Implement decontamination procedures for any worker who may have been exposed, including controlled removal and laundering of workwear.
- Dispose of all suspected ACM waste through a licensed waste carrier — never in general waste.
These steps are not optional extras. They are the minimum standard expected under the Control of Asbestos Regulations and HSE guidance.
Asbestos Surveys for Garage and Workshop Premises Across the UK

Frequently Asked Questions
Are asbestos brake pads still found in vehicles on UK roads today?
Yes. While asbestos was banned in new vehicle parts in the UK and EU, many older vehicles — particularly those manufactured before the mid-1990s — still contain original asbestos-containing brake pads, linings, and clutch components. Classic cars, vintage vehicles, and older commercial vehicles are the most likely to retain these original parts. Any vehicle of this age should be treated as potentially containing ACMs until professionally tested.
Can I identify asbestos brake pads by looking at them?
No. Asbestos fibres are microscopic and cannot be identified by visual inspection alone. The only reliable way to confirm whether a component contains asbestos is through laboratory analysis of a sample taken by a qualified surveyor. Attempting to identify ACMs by appearance, texture, or smell is not safe and not legally sufficient for compliance purposes.
What should I do if I think I have disturbed asbestos in my workshop?
Stop work immediately. Isolate the area and prevent anyone from entering. Do not attempt to clean up any dust or debris yourself. Contact a licensed asbestos contractor to carry out an assessment and, if necessary, arrange for controlled remediation. Report the incident in accordance with your workplace health and safety procedures and seek advice from a qualified asbestos surveyor before resuming work in the affected area.
Do I need an asbestos survey for my garage or workshop premises?
If your premises were built before the mid-1990s, a management survey is the baseline legal requirement under the Control of Asbestos Regulations. If you are planning any refurbishment, structural work, or significant maintenance to the building fabric, a demolition and refurbishment survey is required before work begins. Garages and workshops also need to consider the risk from vehicle components in addition to the building itself.
Are aftermarket brake pads from overseas suppliers safe to use?
Not necessarily. While asbestos is banned in vehicle parts manufactured and sold within the UK and EU, some aftermarket components sourced from outside these markets may still contain asbestos. If you are using parts from non-EU suppliers or working through older stock, have components tested by an accredited laboratory before use. This is particularly relevant for brake pads, clutch linings, and gaskets sourced from certain Asian markets where asbestos use in friction materials has continued longer than in the UK.
