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?

It sounds to me like you have put enough fluid through your system, that you should have at least as good a pedal as your overhauled master cylinder gave you. Are your brakes adjusted up properly? I think by your description of what you have done that maybe the "new" master cylinder might have a problem. Make sure your brakes are adjusted up, and bleed carefully one more time, if they are no better I'd return the master cylinder to the seller. | | |
