Clunk when braking in reverse

[steffenk]

I noticed a subtle (but distinct) clunk that happens when I step on the brake while moving in reverse. It only happens the first time the car is put into reverse. For example, if I back up a few feet and brake, I hear the sound/clunk; if I then continue a few feet more in reverse and step on the brake, there is no sound/clunk.

To get the sound/clunk to return, I have to drive forward a few feet and stop; then, when I reverse a few feet, the clunk returns.

This clunk is very reproducible. Discs/pads on all four wheels were just replaced along with sway bar and right tie rod.

Any ideas?

My first guess based on my own experiences is to check the brake hardware, especially the bracket-to-knuckle bolts. It sound to me like you may have a loose one, or may be missing one.

Pull the wheel off and verify that you have 2 bolts that hold the caliper bracket to the knuckle, and then verify that you have 2 bolts holding the caliper to the bracket. Then make sure they are all tight. Rinse and repeat for each wheel of the car.

My guess is the same as hoov's....something gone funky in the brake hardware. I have seen it happen plenty of times. My second guess if that fails is whats wrong with my car, Strut mount berings are seized up causing a noticable CLUNK when braking in reverse or turning in reverse....and only happens once after the car sits in the morning...rest of the day OK.
