Hi I'm back with another problem. All new brake system from master cylinder to wheel cylinders. Used teflon tape on all threads and have spotted no leaks. We have pumped nearly two large bottles of fluid through the system and still can not get a consistant pedal. We can get a pressure build up after a few pumps but it goes away after a very short time. Started from back and worked forward many times. Still no luck any ideas? I have not put new brake shoes on truck but there was still a decent amount of material left. Also I have noticed no leaking from the drums.
Is there a secret to bleeding the master cylinder that I could have skipped?
thanks for the help,Eric

 

Eric it's possiable that you have a bad MC. Are you using the single pumper. Do the back first and then go to the front.
Did you get a new, rebuilt, or remanufactored MC
Get a new or reman only.

I always appreciate the help I get from this board. Heaven knows I need it

 

Did you remember to bench bleed the MS before installation, this could cause exessive bleeding time if this was not done before being put into the system.

 

I forgot to bench bleed the master cylinder. But what is even more painfully obvious now is I forgot to screw the brake shoes all the way out! I am glad you can learn from asking questions-there maybe hope for me yet!

Once again thanks for the help,Its always appreciated,Eric
