Hi.I have a Toyota 4runner and the right rear brake is sticking how do I fix?

Question

I just replaced the drums,pads and wheel cylinders and the right rear wheel is sticking.It will not release.It did it before I replaced the parts and it is still acting the same way just worse.I was thinking it was an ABS sensor but there are alot of other things it could be.The brake pedal is soft as well and I have bled the brakes SEVEN times in the correct order.Could there be air somewhere in the system?I would appreciate any help.Thanks

Answer 1

If it has an emergency or a auto brake adjuster, I would check that, they do tend to seize up. It is possible that there could be a blockage in the junction box that feeds that wheel or a blockage in the line itself not releasing the pressure when you take your foot off the brake pedal. If the rubber hoses for the brake lines are old, replace them because they do break down on the inside causing residue to get into the fluid. ABS sensors will not cause brakes to seize up

Answer 2

If you have disk brakes in the rear, try replacing the brake hose on that side. Brake hoses can break down on the inside and cause restriction. We saw ALOT of that at several of the dealerships I worked at. Wait...you said drums....hmmmmm. If it's worse, thats probably because the shoes are new, and therefore thicker, aggravating the condition....soft pedal could be brake master cylinder, but that wouldnt make one wheel stick...Did you adjust your brake self-adjusters? The need periodic checking and adjusting, and can seize from lack of maintenance. Also, depending on the year of your truck, it may have individual brake hoses in the rear as well, like the disk brake rears. I'd check those things out. ABS sensors typically do not cause a constant drag symptom. Usually you will see the ABS light illuminated on your dashboard, and you may get a chattering from the affected wheel, or it may not work at all. Please note that abs malfunctions will NOT disable your brakes. You just have to drive like we used to. CAREFULLY =) Best of luck to you.
