logix42p 0 Posted January 25, 2007 Sometimes when im using the brakes i push the pedal and there is nothing at all the pedal can literally hit the floor. If i release it and pump few times the pressure seems to build up again.This happens randomly by the looks of things as in one minute i have brakes and the next i dont. They sometime even go whilst braking. Today however there what a horrible buzzing kind of noise coming from the rear. Could this be related or any ideas on the problem. ps its a 1992 VR6 Quote Share this post Link to post Share on other sites
Supercharged 2 Posted January 25, 2007 When was the fluid last changed?? if it wasn't pressure bled then sometimes this can damage the seals on the master cylinder... Could also be a servo leak - check the solid plastic pipe running to the inlet... Noise at the rear sounds like the fuel pump is it's buzzing - so you hear it if you turn the key to ignition 2 (primes) without switching engine on?

Mr Sands 0 Posted January 25, 2007 Yup, always worth giving the system a proper bleed first; my brakes were a little spongy when I bought the VR, but bleeding some air out of the system firmed them up. Quote Share this post Link to post Share on other sites
