Well didn't get a great deal done today because of the weather, but i did try a few things, first i started the car reversed it out of the garage in between the heavy rain showers, Let it warm up then released the hand brake, as i live on a slight gradient, but the car just stood still, all 4 brakes were slightly binding, and, as usual when i put my foot under the pedal and pulled it up, the car slowly started to move forward. Now i have read about the spring in the servo becoming week and the air pressure over rides the spring pressure, hence applying the brakes, so to check that it is not the servo, i put a couple of wood chocks about 6 inches in front of the wheels and removed the vacuum pipe from the servo with the engine running, the air was released and ------ nothing happened. So i know it is not the air pressure in the servo that is giving me the problem, i even pressed the brake a few times just in case there was any air somewhere in the servo that had not escaped, but no movement of the car, until i again pulled up on the pedal. Well thats one thing eliminated from my long list of possible causes, just bought a Master cylinder today , going to fit this tomorrow, will update with results in the next exiting episode of "The brakes from hell "
