Okay, here's my problem. Bought a 1963 F100, shipped it home and discovered a major brake problem.

Problem: step on the brake, pulls HARD right. I figure, well, this will be easy -- it's gotta be the left wheel cylinder is shot.

Attempted solution: I take brakes apart, pull off left front brake line and its dry as a bone. It's corroded and pinched at the steering box. Run new lines, replace all wheel cylinders and master cylinder. All cylinders getting fluid and brakes engaging.

Drive it, step on brakes and it still pulls HARD right. Help!

Could it be suspension or steering box related? Can't figure this one out.

Thanks!

Not likely suspension or steering. Anything out of "balance" in the system will cause pulling. If either side wheel cylinder is not functioning well, if the brakes are not adjusted equally on both sides or even if the brake drums have different surfaces it will cause pulling. You need to check out the whole system, make sure all shoes have equal thickness of material and are not contaminated with grease or brake fluid. Make sure all lines are clear and wheel cylinders functioning, all shoes are adjusted to the same freeplay and, finally, turn all drums for equal frictional surfaces.

 

Technically it's possible for a wheel bearing out of adjustment to do this though I doubt that is the case here, since you've done so much maintenance and gone through everything.

One thing to look for is of course old rubber brake hose, it sounds though, as if you've replaced both the hard line and the hoses? One thing to try is swap drums and see if the problem migrates. They aren't out of round or oversized from turning?
