Truck pulls right while braking - need some suggestions

strokinaround · Jan 21, 2014

Alright, I need a little advice here,
I've done some searching around but still can't find a solution to the problem. Truck is an 05 4x4. I've already replaced both calipers, lines, and pads, but it still dives to the right when I brake. My next guess would be the abs pump?? Any suggestions would be great. Thanks.

Had a 02 f250 that did the same thing and i couldnt figure it out. Ended up needing to put new hub lockouts in and the pull stopped. I have no idea if the lockouts had anything to do with it tho.
Deff was crazy annoying while towing because the pull was twice as bad pulling 6,000 pounds.

Yea I wondered if it was 4x4 related. The hubs aren't locked in and the tires spin freely though. I had a guy tell me it was abs but I'm not throwing any abs codes? The calipers helped a little but it is deff still doing it. The mechanic I took it to was stumped.

Did you get all the air out when you swapped the calipers? I had to bleed mine quite a bit to get them even .

Yup I did. It was doing it bad before I replaced the calipers. It's somewhat better now but I still have to hold onto the wheel while stopping or else it heads right. I've also check tie rods and they appear to be fine. Have you heard of it ever being the abs pump??

No , but I learn something new every day !

Sounds like you put a good caliper on a bad slide pin that's causing your problems. Unfortunately the uneven pressure will ruin that caliper and rotor too.

If you take it apart and the slides are all lubed and move freely then the brakes aren't bled.

I fought an issue like this and I got pissed and replaced it all. It worked but the slide was tye culprit.

could be a bad valve in the master cylinder. Lets say you get a hole in the brake line on the left hose, the valve will divert the brake fluid away from that side essentially sealing off the leak so as to no lose all the brake fluid. it's basically a safety feature. If the valve is stuck to one side your truck will pull to that side because all the brake fluid is sent to that side. It can be reset by stomping on the brake pedal as hard as you can. it may take some doing but eventually it will straighten out. This may not be the issue but it happens more than you'd think.

Awesome. Thanks for the replies guys. Much appreciated. I'm gonna do some more messing with it tomorrow and see what happens. The guy that aligned it for me swears it's the abs pump but I've never heard of that being a problem.

It could be. It sounds less ominous than that to me. Sounds like worn/misaligned brakes.

Well the first thing I did was take it to get aligned last week. After they were done toying with it the driver side tire is leaning in towards the right extremely bad. So that didn't help things at all. They're doing the alignment again in the morning to fix that tire. I tried stomping on the brake a few times like IrishCream suggested but hasn't seemed to help yet.

Yea, it wont. I could have told you that. I was about to ask if he was serious.

strokinaround · Jan 22, 2014

I wondered but what the hell. It was simple enough. Figured I'd try.

Well I took it for another alignment this morning and that seemed to fix my problem. Doesn't pull at all anymore. Thanks again for all the posts.
