I have a 97 LX450 with 243k on it. When it was bought it had a bad brake booster. I replaced with an aftermarket unit, drove it and it had a pull to the left when braking. I then replaced the master cylinder, both front brake calipers, flex lines and bleed the whole system. Still has a pull ti the left under braking. All suspension bushings have been checked and check good. Please help.
 
What condition are the rear brakes? I had a pull for awhile. It ended up one of the rear pads was wearing on an angle due to missing a clip.

How about tire condition, or alignment? Is the 80 lifted?
 
Rear brakes are good, no lift, tires are new and alignment is straight.
 
How about your wheel bearings? If one is loose that side will have a lag making it initially pull to one side.
 
When I replaced the calipers I resurfaced the roters, replaced the pads and replaced the wheel bearings but it is something to look at.
 
scrowley gave you some good things to check. You have a brake on one side providing more friction when applied than on the other side. If the brake hardware is all actually good (re-check), then re-check wheel bearings. Then re-bleed, as a bubble on one side could do this. The potential causes are somewhat limited.
 
Thanks for the info guys but i really have checked, rechecked then checked it all again and still have a pull under braking.
 
A pull only under braking is usually related to brakes.

A pull that gets worse under braking could be alignment or tires.

Did you get an alignment done when you put on new tires? Did you get a print out? Just because the shop says your alignment is okay doesn't necessarily mean its actually good.

When did you first notice the brake pull? Does the steering yank to the side it's pulling to, or does it stay straight and the car veer over a lane?
 
86 Tuning those are some good questions. What's the conclusions to the wheel either pulling or not? I'm curious.

Also another possiblity is contaminated rotors.
I notice that my truck still pulls to the pass side hard when it is raining. That has been stumping me for awhile. Was thinking maybe contaminated rotor but IDK.
 
Also look for kinked/pinched brake lines on the OTHER side of the truck - you may be pulling left because the right brake isn't building pressure as fast as it should.

I've never dug into my brakes enough to know off hand, but there could be a residual valve on the right side which is malfunctioning, meaning that the right-hand brake caliper has to move much further before engaging than the left does.

Good luck.

Steering yanking would make me look closely at the front brakes.

If you think your rotors are dirty it's nothing that 10 minutes with coarse sandpaper won't fix. Sand down the pads a bit too while it is apart.

Good points. Damaged brake hoses from previous service can definitely be an issue.

I refuse to clamp brake hoses for this reason. If I'm taking a caliper off, I'd rather let the brake fluid drip into a pan. I give apprentices crap all the time if they try to clamp a hose. I teach them to have the new parts ready and then quickly do a hot swap instead of clamping/crimping hoses.
 
As noted in post #7, did you re-bleed???
 
Lots of things can cause your truck to pull when you apply the brakes, but having a bubble in one caliper (or anywhere) is not one of them.

Forget about bleeding your brakes to correct a pulling problem.
 
So much for bleeding. Pin_Head likely knows more about this.
 
I know your calipers are new, have you inspected them in operation?
Pull the pads and replace them with wood, now try the brakes and see what happens.
Try a lite brake application first working towards full application while checking.
make sure the pistons retract easily.
 
Thanks for all the advice everybody just not getting that aha, there it is. I am a Nissan/Toyota tech of over 20 years so yes the brakes have been bleed and the wheel bearing have been installed correctly and re checked. Again thanks for the input.
 
20 yr. novice tech, so you should have found the problem by now and let us now the answer.
 
Ready for a dumb reply? Do you have a leaky knuckle?
After I put on my lift, it was pulling. Back then brakes scared me (screw up, can't stop, death) so I brought it in. Guy said brakes are fine, but knuckle goo is leaking on one side making it pull to the other side.

I'm sure you checked this. . .
