Dear Font of Knowledge
The Problem:
My R32 rear brakes are dragging to the point where they are smoking hot after a 10 minute drive. Both sides. When I lift the rear the hubs can't be turned by hand.
My Attempted Solutions:
1. Replaced wheel bearings thinking the heat and noise was coming from them. This was incorrect....
2. Overhauled calipers with a new set of piston and dust seals. Still got the problem...
3. Triple checked that the handbrake shoes were not dragging on the drums.
Next thought was to check if there is retained pressure in the lines holding the pistons in after release. I released the bleed valve and voila a squirt of fluid and I could turn the hubs again.
So:
Do I pull off the master cylinder, can the piston stick in one direction? It was new when installed in the car, only done a couple of thou km.
The brake line may be blocked? Only in one direction? Back brakes only?
Your thoughts greatfully appreciated
