GMTech1,
I assumed this to be the case with the breaks not working in the order, but could it be the assembly attached to the master cylinder? If so, what is it called?
I tried bleeding at the two break calipers that had no pressure, and got nothing, so as a last resort tried at the two bleeders attached to the unknown assembly/manifold.
I've seen something similar on k series trucks but it would be the rear breaks not working, and it is always the master cylinder if there is no pressure to the wheel cylinders... The only differance is a standard Front/Rear system with out the ABS manifold?
