What might be wrong with my anti-lock brakes

[Brad Schultz 2]

Swapped out the newer hub which I believed was giving me trouble. No change. Still get the right front (RF) wheel braking hard and pulling to the right when almost to a stop as the anti-lock kicks in on dry pavement. Use to be only in a slight right turn but all that changed and will do it anytime, as well as in reverse. So, that being said, I replaced the RF hub, removed and cleaned the rear axle sensor. I get no problem indication. Any ideas?

Looks like you might have a caliper piston jamming in its bore. As they age the surface of the piston becomes pitted from the brake fluid getting dirty, then they dont slide easily in their bore, and then they barely move. :fire: New calipers arent too costly, but they have a big core charge so that you will bring your old calipers back to the parts store. :supercool:

Left hub is bad....... The abs brakes are releasing the wheel it thinks is locking up, So the truck will pull Right if the left is acting up...

Todd is right although I will add that it could also be a sensor issue, but regardless the problem lies in the left front. Someone here not long ago had this same issue and I expliained the logic behind what was going on.

Todd and I1teck are correct. Swapped the newer used hub from RS to the LS and braking so far seems normal. Getting good at changing them too!
