I have been fighting a low soft pedal for a long time. I have replace every component in the system beside the ABS unit on the frame (have by passed it and is not the problem) and the wheel cylinders in the past year. I upgraded to the chevy wheel cylinder that are are in the sticky about 4 years ago.

So here is what i found yesterday, i figured i would bleed the brakes again just to eliminate air in the system. I start with the ABS unit and get a little air out of if. Go over the the passenger side rear and get a lot of air. I run a quart of fluid though it and can not get the air to stop coming out. I go to the other three wheels and i get no air out of them.

I just had the passenger side drum off about 2 months ago and did not notice any fluid on anything. i have noticed a small drop in fluid in the rear portion of the master but figured it was poor sealing lid on the master.

Would a leaking wheel cylinder cause this? I am going to replace both anyway but i figured i would ask first.

It sure sounds like a leak in there somewhere. Mine was the same, except I always got air from the drivers side rear, and hardly any from the other side or the valve. I always suspected that the proportioning valve had something to do with the weird bleedind results...Mayk

Well after 4 days of driving they are spongy again. No fluid leaks I can see guess I am going to replace both cylinders and see what happens.
