My R34 rear brakes are squealing bad. its only coming from the left rear side.. I have read heaps of forum for a solution but could not fix it.
The squeal comes only on low speeds 0-30km/h while breaking. Like when im trying to stop in a trafic light or just slowing down to stop.
So far I have changed the Rotors (RDS Slotted)
Changed the Pads (Bandix Extreme)
Installed a new shim kit with backing plates..
Tried Copper grease on all the metal components except on the rotters and the front of the brake pad..
Grind the pads on concrete..
My mechanic told me that the calliper and the pistons are working fine..
I can’t think of anything else to do.. The squealing noise is too loud.. Need help please..
