ok brakes have been working fine no hickups until the other day and i was swapping the cars around on the drive, went to brake, and the peddle just went rite to the floor! luckily the car did stop when it hit the floor but there was no gradual slowing. i took the back wheels off yesterday found a leak on both sides were the hose connects to the caliper. took the bolts off tidied them up and it looks like i've fixed the leak. However the pedal is still not getting firm again even after bleeding the air out of the lines. Can anyone be of any help? is it the servo? oh and this is only happening when the engine is started otherwise the brake is still firm, which leads me from the suspicion of it being the servo?
thanks in advance,
