Brakes sucked when I got the car, leaking caliper, bad master. Got all new wheel bearings, new rotors, pads, master. No leaks in the system. I have to mash the brake pedal down and it still takes lots of effort to stop. My last 914 was not like this. The mechanic adjusted them but think he forgot to check the pedal adjustment. Any tips to this? Am I missing something. This is about the brake pedal movement to stopping the car. Even at a red light I need to use alot of pressure to keep the car from rolling. The brake pedal should not have that much effort. Really makes the car not fun to drive. And there is really no bite to the calipers to slow it down if I have to slam on the brakes.

From the sound of it I believe you have a faulty MC...with a 17mm MC the pedal should be very compliant.

I would think 2 bad ones would be kinda rare. There are no visible leaks in the system and the fluid is full. Auto Atlanta mentioned it might be the flex lines. I have not replaced them. I am trying to send the first leaking master cylinder back to Auto Atlanta in exchange for some new flex lines. I will then have those replaced and the system bled again to see if issue is fixed. Auto Atlanta has always taken care of me in the past. |

I will then have those replaced and the system bled again to see if issue is fixed. If your flex lines are restricting the flow so much that it is making a "hard pedal" then they are restricted enough to cause the calipers to bind after release. Jack up one end of the car and spin a wheel and press the brakes. See if the brakes grab abruptly or slowly. Then once they have grabbed, release the pedal and see if they release immediately. |
