What does it mean when your car Judders when braking?
In a broad sense, brake judder is caused by vibration. When this happens, it passes up from the brakes, through the suspension, and on upwards into the steering wheel, potentially resulting in a violent judder. This effect is likely to create a reflex reaction forcing you to grip the steering wheel tighter.
What causes a vibration while braking?
Brake shudder is the vibration that you feel through the steering wheel when you hit the brakes. If your brake discs are unevenly worn the brake pads come in contact with the flat spots present in the rotor’s surface which causes the vibration that we call brake shudder.
What should I do if I have brake Shudder?
If this is evident, clean the area with some sandpaper and WD40 until the rust and scale is gone. This should be common practice when replacing or refitting brake discs to help prevent any instances of brake shudder in the future. When installing a new set of brake pads, it’s important to bed them in properly.
What causes a steering wheel to judder when braking?
Brake judder can be caused by a badly fitted brake disc pulling out of alignment with the hub or caliper.

When to replace the brake pads and discs?
Each time you fit new brake pads, inform drivers that they should avoid hard braking for the first 200 km. When poor bedding-in has resulted in slight DTV, it may be sufficient to bed in the brakes once again. If this does not re-align the disc surfaces, the only solution is to replace both the brake pads and discs.
