Hey guys. I gotta brake problem I cant seem to solve. I have a 49 Chevy 3100 with the original brake setup. First off, I rebuilt the master cylinder myself but it had one bad pit in the cylinder but went ahead and tried it.
After bleeding and bleeding, it still took about 3 pumps on the pedal to get the brakes to stop the truck. So i figured it was that bad pit in the cylinder so I went ahead and bought a new master cylinder.
Installed it today and started bleeding brakes. Well after bleeding and bleeding, It takes about 10 pumps to get anything. Ive went through a whole 32 oz bottle of fluid and still no progress. After alot of pumping on the pedal, I only get about half pedal, then it dissappears after releasing for a few seconds.
So now the brakes are alot worse with the new cylinder than the old pitted one.
Any ideas what could be wrong? Could the new MC be bad?
