Service and repair tips from Bosch: Brake pads
As a strong partner with extensive expertise in brakes, we offer your workshop everything you need for the efficient maintenance and repair of brake systems: first-class products, reliable service offerings and efficient diagnostic technology.
Identifying and solving the most common problems with brake pads:
There are many causes of vibration and noise during braking. These are not always the result of worn brake pads. You should therefore always check the brake pads regularly to better identify the actual causes of braking problems.
Wear on one side only Cause:
- Brake caliper and/or brake caliper piston is blocked
- Guiding of the caliper does not work properly
Effect:
- Vehicle pulls to one side during braking
- Faster and/or uneven brake pad wear
Recommendation:
- Check the brake caliper and replace if necessary
- Replace the brake pads
Conical wear – vertical or horizontal Cause:
- Worn brake caliper seals and/or spring
- Excessive operating clearance of the caliper
Effect:
- Premature brake pad wear
- Braking noise
Recommendation:
- Check the brake caliper and replace if necessary
- Replace the brake pads
Grooves and scoring in the friction material Cause:
- Dust or metal particles on the contact surface of the brake pad or brake disc
- Scratches on the surface of the brake disc
Effect:
- Braking noise
- Vibration during braking
- Affected braking efficiency
Recommendation:
- Check the brake disc and replace if necessary
- Replace the brake pads
Cracks or broken edges in the friction material
Cause:
- Extreme heat buildup due to constant contact between the brake pad and brake disc
- Bending of the brake pad backing plate
- Brake caliper or brake caliper piston is blocked
Effect:
- Braking noise
- Vehicle pulls to one side during braking
- Overheating on one wheel
- Uneven brake pad wear
Recommendation:
- Check the brake caliper and replace if necessary
- Replace the brake pads
Bosch will be exhibiting at this year’s Auto Trade EXPO, which takes place from Saturday and Sunday, October 15-16 at the RDS Simmonscourt in Dublin.
