Hi, I hope someone can offer me some suggestions. Recently, driving my Bond Equipe, I suddenly lost all brake pressure, the pedal went straight to the floor without any resistance. I pulled over and soon afterwards, the pedal was back to normal. Whilst parked, I removed the master cylinder cap, expecting to find the fluid low, but actually it overflowed. I also jacked the rear up and the brakes were not binding at all and there were no signs of any leaks anywhere. I drove twenty miles home with no problems. I don't think the brakes overheated.
However on closer examination, the master cylinder looked old and crusty and may have leaked a little, so I decided to replace the master cylinder. I have now done this and after bleeding, the pedal felt great. Unfortunately, the next day, the pedal went straight to the floor again with no resistance and then on the second press was perfect again. So I seem to have intermittent loss of brake pressure. I replaced the rear drums, wheel cylinders and shoes about 18 months ago (less than 1000 miles). There is no servo on the Bond. The master cylinder I have fitted is actually a clutch master cylinder, but I can't see why this would create an intermittent problem (which I already had before I fitted it)
Any suggestions gratefully received.
Dave.
