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! |

The "pad guides" cast into the caliper should have the same spacing away from the rotor face on both sides of the caliper (YELLOW arrow).
The lube that I use was a VW part that was dropped 10 or 20 years ago called Brake assembly paste. Probably from ATE. Since it is a big as a toothpaste tube, it has lasted a hundred or more caliper rebuilds. |
