i have tryed to bleed the brakes on my old combe van i have done all four wheel but it still seems to need doing ,????is there any more bleeding nipple that i may have over looked?
if you've been pumping the brake pedal, you may have turned the seals inside out in the master cylinder. this is a common problem on vauxhalls. it's usually better to use a pressure bleeder or a vacuum bleeder on these.
