ok, so I converted my 914 rear brakes to vented disc with 911 M calipers and internal drum parking brakes. Brakes work great but the pedal travel is longer than it should be. Went to rebleed everything and found that one of the rear calipers had a pad to disc clearance of .010" which probably explains the travel. Also verified that the pistons were working and not hanging up.
I've got a rebuilt proportioning valve from PMB that is working correctly. Running an ATE 19mm MC (bought a new one thinking it had the 17mm). No bubbles in the system using ATE SuperBlue brake fluid. I've never seen a caliper piston release that far just on one side. Anyone have any ideas? This is frustrating! |

Thaks , davep. I goggled for brake assembly lube , from what I read ( ??) it seems that ATE brake paste is not allowed to be inported for evironmental / msds stuff , so I search on. Thanks again.
tomeric914 , it sounds like your caliper pistons are sticking , and the rebuild should fix that , as for the .030 shims ,thats not a lot and would probably be offset by the caliper rebuild, but hey , if ya gotta do it ,do it right. Yopu can get shim stock ( stainless , brass ,etc ) by the roll off of ebay fairly cheap , or maybe Napa carrys shim stock . Good luk Jaxdream |
