Hows your Control Arm Bushings and Ball Joints???

:w

Doesn't matter if it don't pull while driving,There is allot more force on them when you hit the brakes!:thumb

A bad control arm bushing or ball joint may not be noticeable while cruising,But Jerk the wheel out of your hands as soon as you tap the brakes!~!!:thumb:thumb

Brake problems ?

Old hoses coming apart internally will damn sure cause the problem too!

I don't know the here & what, but the type of brake fluid you used and as mentioned above, suspension could cause it, but I'd think if the ball joints were that bad the wheel would buckle under the car on a heavy braking situation. Like wise I'd rule out the mastercylinder or proportioning valve as the entire from brakes would or wouldn't work. I'd pull out the bleeder valves and pump a quart of type 3 brake fluid through it to see if any rubber hose particle pieces come out. If not Tighten the bleeder valves back in and try bleeding all the way around stating with the wheel furthest from the master cylinder. GMJUNKIE is the one voice I trust no matter what ?
