Help - 80q rear calliper
Well I'm at my witt's end. The rear
calliper (R. side) is not releasing once again. They were both replaced
about 9 mo ago, and this one will be under warranty... but out of stock.
So, I've been waiting about 6 wks now... Now, I just need to get it back
on the road until the new one comes.
Things I've tried:
- Loosening the bleeder (to prove it's not hydraulic pressure
on the piston). I believe this rules out the master
- removing parking brake cable - rules out cable
Each time after reassembly, I've pumped the brakes only to
find it locked up. It can be released by pushing the calliper inward or
outward, but only to lockup with next brake application. This seems to
indicate internal binding. Is there a way to disassemble the guts to clean
up the insides and the parking brake mechanism? I've tried to turn the
piston by placing a crude allen wrench (aka bolt), but haven't been
successful. I get about 1 full turn before it quits.
Any suggestions? It's a GIRLING 36.
'90 80q - deerless at last, but too much
