Last weekend I drove freshly repainted Mistress into Lexington for display at a local car exhibition, and a few blocks from the site the brake petal went clear to the floor without notice! Yikes!!! Didn't pump up at all, and thank goodness for the hand brake. When the show was over and temps had cooled down, I was able to get her the 17 mi. home with brakes acting normal? Power bled the brake lines twice, and she drove normally twice during the week. Back to Lexington yesterday, and again the petal went straight to the floor in the city traffic, way too much excitement for me! The common denominator both times was high air temperatures, and again she behaved well on the return trip home when things had cooled down. There are no leaks at the master cylinder, fresh brake fluid levels still full, so I suspect that an 8 yr. old 19mm MC has failed, on a 1973 in otherwise excellent condition with 54K miles. What else does this 914 brain trust group think could be the problem? Should I just go ahead and order a new MC? (IMG:style_emoticons/default/WTF.gif)

QUOTE Or...a problem like I had. My front left caliper was dragging and causing the brake fluid to boil. Pedal goes straight to the floor when that happens. Once I let it cool down the brakes returned.Drive the car a couple of miles and feel your rims. If one of the rims is very hot you are boiling your brake fluid. I have had that exact problem. It would only happen on long drives where the front caliper would get hot enough. |
