As I slowly go through stuff on the 914 I bought I have now come to the parking brake. The cable setup works fine. When I took off the driver side rear wheel to check out the operation, the actuating lever was moving fine but there was no "lock up" of the brake. After adjusting the venting clearance per Haynes, still no lock up. Normal braking operations with the pedal seems to work fine.

I have everything apart now. As it turns out the rotors are way below spec minimum so they are going to be changed. But while I have it all out I am wondering if there is anything I can do to fix the parking brake action... or maybe my venting adjustment was done improperly. Anybody else run across this problem?

Tom at Pelican and a local Porsche mechanic both agree that a rear caliper rebuild is an iffy proposition.

Also after I have everything back together I will want to bleed the back brakes. I notice that I have two bleeder valves on each caliper. Is bleeding through both necessary? What is the correct approach?
