I have an old thread about bleeding the abs,well I had it done with scan tool and I still got a low pedal,have a new master..which I didn't need to buy..i bled brakes again and nothing much better,the pedal goes down low..i have a bad wheel sensor on left front,its unplugged but bled the abs around it..what next? hard to adjust shoes in back..stupid design.

Bleed in this order...

If no special tools are available, you will need a helper to do this. Then an ABS bleed will need to be done.

did them all,then had abs done,then re bled them all over...still crappy.

Something is wrong somewhere.

no kidding,want to just replumb it without the dam abs...

they were ok,then rear one froze on me and wheel cyl popped apart..had no brakes then.lucky me I was in driveway,since then cant get pedal back..

I ran into this once, with my *-10, w/ABS.....bled the brakes.....even pulled a vacuum on the lines and had a mushy, low pedal......

What I had to do, was hit the brakes HARD several times(in Park) and rebleed the system to get a good pedal.....

what do you mean? I have been pushing hard on it in park..

stuck proportion valve?

I don't apply the brake pedal and push as hard as you can......I mean shock it, by hitting the pedal hard right from the get go, several times.....

I'm not sure where your ABS valves are on a 1500, on my *-10, it was up high to the right........the lines went into the top and out the top......so after shocking the system, you must bleed the system at the ABS valves first(input and output lines), before going to the wheels.....
