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. Therefore, you should check 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 seized
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
Improper 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 build-up 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 seized

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
