    Default clunk / knock when braking?

    as above.. can be felt through pedal sometimes i think....

    sometimes as soon as pedal is pressed, sometimes just as the car stops.

    got an idea myself, but want others opinions of causes.

    Do you only get it when you have to brake quite hard? Or from a high speed?

    Check caliper carrier bolts are tight and caliper to carrier slider bolts.

    if it does it when just about to stop, it could be 1 of the ABS rings split, or as gary said check your caliper bolts

    I used to get a similar noise when I used third party brake pads on my Omega (apparently they fit about 10 different cars!) and it was cured when I used Mintex pads.

    Maybe the pads moving slightly in the caliper frame if they're not a perfect fit?
