Ok so I have had a brake pull to right for quite some time now. It also has a slight pull to the right while driving. Really it has been for 3 years but not consistent. it comes and goes and now it seems to be here to stay.

So here is some back ground.3 years ago when I bought the truck I installed new front rotors, pads, turned rear rotors, new pads, new ball joints and new right front caliper thinking it was sticking. Truck still pulled to the right occasionally. I warped the front rotors about a year ago when my trailer brakes went out on a 2k mile trip. Around that time i drained all the brake fluid and put fresh fluid in, that actually made the brake pull less. So about 6 months ago I turned the front rotors and greased all the slides again and that took some of the warpage out of the front. It didn't last long so I replaced the front rotors only. I Noticed the boots were bad on the front right caliper pistons so I replaced it. now the pull is worse! So today I replaced the left front caliper thinking it was sticking but it still pulls BAD! Bad enough to change lanes on me while hard braking!! I have inspected the rear calipers and slides and they appear to be working correctly.

After doing some research I think I might swap the front pads side to side and see if that changes anything. Also I am thinking about replacing the front rubber brake lines. I have heard some have had problems with blockage in these lines which cause brake pull. the other thing I think I will go tomorrow is see which wheels are hot after driving.

What do you guys think?? I am running out of options here!

 

Slide pins! Pull and grease.

 

I think you are on the right track with the Brake hoses. Others will chime in with ideas, but it looks to me like you have pretty much tried everything. Good luck

 

I have greased every single one. They slide perfectly. It's not the pins

 

My hub bearings were shot on my 4x4 and were causing these same issues. I've also had slide pins cause this same issue. If you have a 4x4, check your hubs.

 

I have new hubs too. Pass side is maybe 2 years old and pass side is 1 month old. Both feel good.

 

Hmmm. Only when you apply brakes it does this? No wander when coasting /cruising?

 

Next step is to get an Infrared thermo and start checking temps on all four wheels.

 

Watching this one.

 

Have you checked the master cylinder and steel line connections? Bleeding the brakes by pumping the pedal can damage the master if you depress the pedal past its normal range of motion in the process. You can end up moving the piston past where it normally runs and ruin the seal if there is any corrosion.

 

Good one!

If you ever use the parking brake, one side can easily be siezed... which can cause some pull.

This doesn't sound so much like one side is pulling hard... but more like the other side is weak. Turning warped drums? Replacing parts on one side at a time!? When I do brakes, both sides get the same treatment at the same time... but front-to-back is another issue. I had a burned brake with a warped rotor in the left-rear from a sticking caliper. Both sides got shiny parts: PB shoes and hardware, pads, calipers, and rotors. Six months later, fronts gave out and I replaced pads, rotors, and calipers.

 

It pulls really bad when braking. And there is a slight pull when driving which lead me to believe it was sticking slides but it is not.

I think this Friday I'm going to take it to an alignment shop to rule out any alignment problem.

 

I will take a closer look at these lines. I have looked at everything but I'm going to take a closer look. When we bleed the brakes we were using a vacuume bleeder.

 

Haha I knew I was going to get in trouble for not replacing everything at once. When I turned the rear rotors they were not that badly warped so i figured i could save a little cash. I know I should have just replace them but funds were a little tight after all the new stuff in the front. Same with the front caliper. Now it has two new front calipers within a month of each other.

 

If something is dragging and it warms up when you go to apply the brakes that side won't have as much stopping power since its already hot. Maybe its sticking just enough to decrease brake performance but not badly enough to be noticeable while coasting? This could be exasperated by the front end being out of alignment.
