Help, I am getting very frustrated with my car. 1973 MGB dual line, non-servo
brakes. I asked a few weeks ago about a replacement for a master cylinder, so
I decided to order a new one from LBCarco.
To recap, front brake lines started leaking somewhere, checked connections,
nothing, but the line was wet. I replaced the front lines. So far so, good,
only when I hit the brakes gradually the pedal slowly goes to the floor without
really stopping. However if I stab the brakes the car squealed (sp) to a stop.
Okay figured master cylinder, so I replaced it today.
Went ahead and attempted to bleed the brakes with a friend that has helped me
bleed the brakes before.
I first put the MC in without the lines connected and put in a little fluid and
pumped until the fluid came out of the fittings (to prime the MC). I then
hooked up lines and proceeded to bleed like normal, only something was not
quite right. I had to depress the pedal about two inches to get it to brake.
I don't think this seems right but I tested it around our block. I could lock
up the brakes, but it took an incredible amount of pedal effort and that is
when the brake warning light came on. I figured that I had not bled them the
right way, so I tried again.
For some reason when bleeding back brakes the pressure goes down and does not
return? Could the rear brake adjuster affect this? Any other ideas?
Thank you
