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 |

That 20 years limit applies to ANYTHING made out of rubber in the brake hydraulic circuit!
Master cylinder Front calipers Pressure regulator (mistakenly called a proportioning valve) Brake lines The rear calipers and the regulator should ONLY go to PMB IMO. The other stuff is less critical to source but if you get it all from PMB you have the "Eric" guarantee which is KICK ASS! See this thread for RECENT BS. http://www.914world.com/bbs2/index.php?showtopic=371186 Even PMB can have troubles! This shit is OLD It's how they back their stuff up that is the important part.
