front brakes

[quote:b937fa202f="Spiker"]Hello
I'm working on an '86 Chev 1/2 ton 2 wheel drive pickup w/ 6.4L diesel and auto trans.It has 90K miles.
When I step on the brake pedal the vehicle jerks to the right also causing the steering wheel to jerk.
I have replaced the front calipers w/pads. Had the rotors turned. Repacked the wheel bearings. Checked the rubber hoses connecting to the calipers for expansion under pressure. Checked the rear brakes. Got an alignment.
I still have the same problem.
Any suggestions?
Thanks.[/quote:b937fa202f]

Could be dragging brakes/loose wheel bearings/brake hose acting like check valve/rotor thickness again-mike it and recheck.
