just started this night. went up town and it the brakes a little hard and heard it screahin a lil then i went to drive then hit the brakes and it pulled to the right. only does it when the brake pedal is pushed 1/3 the way or more.

 

Sounds like a stuck caliper to me. Mine did that before I replaced both calipers. Not too hard to fix.

i thought it was a caliped stickin/hanging up. i had my left replaced for doing the same thing. i do use it off-road a lot and pretty hard. just thought i knocked the allignment out or something. kinda scared me when the wheel and truck outta nowhere just pulled to the right, almost hit a parked car. thanx a lot.

 

If the caliper is OK, check the steering. Make sure the tie rods and any bushings don't have a lot of slop in them. I had a worn out bushing that would cause a pull to one side when breaking because it allowed the one wheel to turn when under a braking load. Jack up the front end and do the tire push/pull test.

 

but would that go out and happen all of a sudden, i didnt exactly slam on the brakes but didnt hit em hard to avoid something and after that it was doing it. ill check that also tho, thanx.

 

I agree, if your calipers are good check for back front end parts. A bad ball joint may do the same thing. Good luck troubleshooting.

upper n lower ball joints on both sides were recently replaced...im gunna take a look at the caliper n tie rod ends n all when the weather gets a little warmer.

 

I just replaced the hoses/calipers on my 1993 F-150. It made a world of difference. Mine used to pull harshly to the left upon braking, but new calipers and hoses solved that problem for less than $40.

I still have a slight pull to the left however, the ball joints don't appear to be my problem. I suspect the tie rod end, the left one is covered in grease.
