Does anyone know how if the handbrake mechanism on the rear calipers can be rebuilt/overhauled on a 1992 Audi 80 2.0 (ABT)? The reason why I ask is that the rear calipers are only just working enough to pass the MOT. With calipers at £100 each I was considering stripping them down and rebuilding them, if a rebuild kit is available.
The discs and pads are new and the calipers are working fine on the foot brake.
Any suggestions please!
