New brakes, new rotor..brakes bled. When i go to apply brakes, right around 10 mph, my truck pulls hard to the left....ideas?

 

Welcome to the site..

What year 250?

 

2002 4wd superduty

 

Calipers were built?

First flag for a dive to either direction (more so if not present prior to the brake work) would be a caliper piston/s dragging or tight in the bore. When you pushed them back to accept the new pads did they move back reasonably easy?

Was common for the caliper dust seals to split open from heat allowing collected debris/water/corrosion to get in between the piston and it's bore. If the seals were split, a rebuild/reseal is a must..

Or, some just push the pistons back without a fluid release during the reset and any settled caliper debris gets pushed back into the brake system in the fluid stream. Pushing the caliper pistons back with a release, then a bleed is the best option. If the front is lifted, brakes applied-released, is the force to rotate each side equal?

 

check the caliper for sticking
