Help! 914 Rear Brake Caliper Piston Retraction???
Posted: Tue Mar 28, 2006 1:26 pm
In an effort to get a shiny new MoT on the 914 for the weekend, I'm trying to get some rear handbrake action. N/S is all sorted courtesy of removing the handbrake cable, freeing it and the hanbrake lever: fine.
The O/S is less simple. Again the cable wasn't very good, so that's now sorted, the pads are now free in the caliper. The problem I've got, is that the piston won't retract properly. I realise there's meant to be a 4mm allen screw that is meant to be adjusted to set the pad clearance, but this and the 'plug' it must mount in appear to be missing (all that's there is a fine female thread roughly 8mm across .
So have I got a slightly different caliper, or is it simply missing the adjuster. If that's the case, why doesn't the piston retract?
Any thoughts?
