I would suggest bleeding the front brake on the opposite caliper from the direction the truck pulls when stopping. I would guess, from your description, that the calipers are not braking evenly.

Agree - if it goes down the road good normally and just gets squirrelly when you hit the brakes - then it's time to focus on brakes.

Check or replace those front hoses, as has been suggested, and double check anything related to calipers - do they slide freely on the knuckle? Are the pistons getting hung up in the bore? Is the friction material wearing (or breaking in) evenly? etc.

Pistons in the bore have been a big problem for this style caliper but it usually causes a problem on one side and stays with that side. The truck goes the opposite direction of the bad caliper because the bad side is not doing it's fair share. Make sure the piston bore is smooth (no screw thread type machine marks) and make sure the leading edge of the piston is free from burrs or roughness (next to the groove where the dust boot seals).
