A mechanical problem with your braking or disc brake system can cause mild or extreme juddering. Most drivers experience this judder pass up from the wheels to the suspension, which can be felt through the steering wheel. If you experience brake judder, take your car to a garage and get it fixed by a skilled mechanic.
We will go through some common causes for brake shudder.
Hub Or Disc Run Out
A poorly fitted disc brake can run out of alignment with the hub and cause a brake judder. The major causes for Disc Run Out are:
- Rust or dirt on the wheel hub surface
- Distorted hub contact surface because of excessive tightening torque
- Distortion of the hub
- Alloy wheels fitted incorrectly
Severe Disc Distortion And Overheating
Hot temperature causes the disc metal to distort in different areas, causing intermittent contact between the pad and disc. This result in a brake judder and the common symptoms are:
- The blue or darker spots on the Disc show brake abuse because of intense braking.
- The deteriorating quality of the brake pad is indicated by the blue or darker spots on the disc.
DTV (Disc Thickness Variation)
A disc should have even thickness throughout if not, then this situation is known as Disc Thickness Variation or DTV. Uneven thickness means that while braking the brake pad loses and regains contact with the disc, causing a brake judder. Some causes for DTV are:
- Bedding-in procedure for Disc or hard braking during the first 200 km not done properly causes DTV related judder.
- Dirt or corrosion on the Disc surface can cause DTV
- Overheated brakes may cause pad imprint on your disc and cause DTV
