Its been doing it for awile now and cant figure out wtf it is.
Every time i step midway on the brakes it starts to knock real loud but once i step through it stops. I get churping noise as the car is driving. The brakes were done in january. Anyone have this problem???? Or some know what the problem is???

Thanks :banghead:

My car has started to make knocking sounds, the rotor was replaced recently. Took the tire off and found several spots of bright metal on metal (rubbing) from the brake assembly on the inside of the rim, replaced the brake pads (there was a worn "spring" which was part of the pad. If you haven't found the problem yet, you could check for that...not sure about the chirping though.

The chirping could be a little bird catching a ride with you.
