Hey everyone.

So we've recently assembled a car and all is well except for the part when I push the brake, the car is clunking in the what feels like to be the "rear passenger side".

The sound happens ONLY when braking and it's like hitting a small hammer to the chassis somewhere.

We have installed new brake discs, pads, wheel bearing has been replaced and the driveshaft has been replaced as well. The only thing that I can still think of is the rear diff, but it would make little to no sense to make a clunking noise from the diff only when braking.

If anyone has any ideas left, getting a bit desperate and very annoyed

 

Up...

 

Random thought (not likely but is possible I guess): could it be the abs sensor tripping and triggering the pulsing.

I had a 96 lancer that I hit a curb in and damaged the abs sensor and that made the abs pulse under "any" braking. I didn't look into it far enough to see if it was isolated to one wheel. However the abs did turn itself off and flicked the abs light on the dash on and you probably would have noticed that.

 

If it is one clunk and you have aftermarket pads then that is normal. It seems the vendors use pad backing plates on the rear pads that are shorter than OEM. I've read this complaint about more than one brand. Maybe they source their backing plates from the same place -dunno.

 

No its continuous tap tap tap until stopping. And its speed related (faster movement, faster clunks)

 

Up.

 

Bump for ideas...

 

could just be the abs like someone said or drive shaft slap. or diff clunk

 

Is there a rock or something embedded into the pad? If its fluctuating with speed and seems to be associated with WHEEL rpm rather than driveline rpm, then I'd start by looking there.
