Stock 914/4 rear brakes.
Pulled the handbrake heavely when parking in a steep hill, released and got away normally (I thought). After 5minutes of driving I felt a smell of smoke and at the traffic lights felt that the car was not rolling freely. Got home after a few minutes ...smoke from rear right...rim hot. Took wheel off, released cable at the caliper, still sticking. Measured the pad to piston gaps, outer 0,20mm inner one zero. Pulled the lever at the caliper backwords (releasing), still sticking, still no inner gap. Pistons moves freely. Tried to adjust the inner gap but could not get it bigger than 0,10mm how much I turned it out...got less if I turned it in so adjuster seems to work ...wheel now moves freely with 0,10mm gap even after using the foot brake hard and then pulling the handbrake and releasing. Yes, guess its time for a caliper rebuild but just cuirios what caused the problem of suddenly no inner pad gap and if its a known phenomen? Edit: More soecific, why did the pad gap go to zero and why could I not adjust it to more than 0.10mm? Lars S |

I'm both a master and a masochist...
I bought the PMB kits. I watched the video. The vid is PRICELESS! Shows you all of the tricks for rebuild. It would be a SHITLOAD harder without the video. I got stuck on removal of the welch plug over the PB arm. I've chopped the crap out of mine and still don't have it out... Saw a set of fresh PMB rears in the classifieds. SMACKED the EASY button! I will finish my original rears somewhere down the road but it's a SHITLOAD easier to just "spend money" regarding the rear calipers. Since I purchased my kits PMB has started offering replating services if you send them your caliper bodies. I WILL be taking advantage of this service! |
