I recently installed a set of AP racing big brake kit. Right after installation, it produce a loud squealing noise during braking. This was resolved after adding brake shim and grease and chamfering the pads. It has a groaning noise when car is in D gear trying to crawl forward while I depressed the brake pedal slightly to catering for creeping of the car. I noticed many auto gear cars have this noise but it didn’t have on my stock brakes. Can any gurus advise please is it his normal and how to resolve it? Thanks.
