911 T powered wershin' machine ?
Some of you know that I recently took delivery of a 70 911T 2 days ago. I have already had tons of help ! Thanks.
I have , of course, another question. When rolling to a stop, the car wil creep up to the stopping point and then abrupty stop as though the brakes were applies or the Ebrake was was up and burned out but still biting a little. Even when sitting on a slight incline the car will stay put. Then when driving at slow spees, you can hear what sounds like a wershing machine. Slosh--slosh--slosh--. Oh yea, the Ebrake IS very very weak, with the ability to hold at almost 0 deg. incline. IS it the E brake? I know you super mechanics have seen or heard this before, As always, TIA Michael |

Your rubber hose maybe bad, this will cause the brakes to stick on. Steve

Jack the car up at the rear and try and spin the wheels. If they spin but stick slighty at certain points of rotation you may have warped or out of spec (worn) discs. Does the car feel as if it is 'pulsing' when you are slowing down? Alternatively, if the wheel will not spin freely at all you may have the E-Brake badly adjusted (as in permanently stuck against the hub), which will just need readjusting (hopefully) or new shoes fitting.
Also you could try taking the car for a short drive using the brakes as little as possible. When you stop feel each of the wheels for heat - if one wheel is significantly warmer to the touch then you have found the problem wheel. Could be a caliper piston not retracting properly etc. Good luck |

Do you have any free play in the brake pedal? I had an issue where the rubber brake pedal stop had wedged itself in such a way that the brake pedal was not fully releasing. Had similar symptoms to what you describe.

I would vote for the flexible brake line. When they get old the I.D. gets smaller. When you step on the brake you can generate more force. The calipers have no force to push the piston back away from the rotor. It's a quick and pretty cheap fix. Most people opt for the stainless brake lines they cost a little more.

No free play in the brake pedal, and the calipers are all rebuilt + brand new rotors. I will try the tricks described above. I'm betting on e brake problems, because the ebrake is shot, and the brakes are new, but the rubber brake line sounds very curious too....
As always, Thanks for all the help, Michael

The noise you hear - is it a 'slosh' or more of a 'scchhh' (technical term), and do the brakes 'pulse' when applied?
