Front disks pulling to the right! - Page 2 - Toyota Nation Forum : Toyota Car and Truck Forums

did you try installing new discs?

It seems that the problem is not really solved and I spoke too soon as now I have new rotors and I refinished the pads and the first thing that is happening is that it is beginning to pull to the right as the disks and pads break in and the right rotor is getting polished much more quickly than the left and the right front wheel is beginning to heat up and I presume that is because the pads are dragging on the rotor. The left side is not heating up. I cleaned and re greased the bushings so everything is floating properly. I mostly drive by myself and the car is listing to the left somewhat but that should not make the right side heat up. I presume there is a balance/control mechanism in the line between the 2 sides that is not allowing the right side to relax. I do not know enough about this to know what it is or how to fix it. These are the second set of pads doing the same thing so it is not them. This is some sort of tricky dilemma. The little separator springs are on the pads.
I thought of one last thing that is new. I repacked the caliper bushings and sleeves with hi-temp lube and possibly I packed them too full in the boots and the bushings might have difficulty moving in them as everything might be too compressed. That would be the latest dilemma. It was cold and running out of time when I completed the bushings. There might be nowhere for the grease to go and sticks the bushings.

DId you ever replace the hoses like bitter suggested? I've personally seen and repaired a vehicle where the brake hoses got so plugged with whatever that they acted like one way valves holding pressure in the calipers. Since you mentioned that the fluid was real dirty, that might not be a bad place to look. Besides, new hoses are always a good idea.

I bled the brakes and got everything comming through clean at all 4 wheels quite some time ago and the hoses do seem to be good and strong without internal problems. It does not seem they are broken down in any way.

The pads should move freely in their mounts . If they bind up you can also get the pull. Remove pads , clean rust from ears on side and on metal pad retainers they mount in. Sometimes rust builds up underneath metal pad retainers so clean up underneath them as well with a wire brush. Make sure you installed the metal springs on the top of pads that fit in holes on top of pads. Hold caliper in hand and be sure you can move glide pins in and out of bores by hand without any binding. If you do all this you shouldn't have a pull or something else is cause. To verify jack up front end put car in neutral. Each wheel should turn freely .

I will have a go at the pad mobility issue possibly today as the weather has improved in my outdoor garage. It does sound as if it might be the reason. Logically I can not think of anything else. I really did not know much about these brakes previous to attempting to solve this but I have learned much.

I took it all down once again. Got the caliper bushings sliding really well and cleaned all around the pads, clips, etc and even polished the pad edges in proper spots to reduce the friction. Knowing it should all be so free of friction is great. When I got it back together it was sliding like a loose goose. I went for a 10min test ride and the wheel was hot from the brake dragging so it is not in the pad, mount issue. It presume it is in the line as the piston seems to come out and will not go back in. I will resume further exploration with the proper time. I suppose I will have to go with a new hose as I cannot think of what might come next.
Thanks,
Sooner or later I will get this.

get a caliper and hose like i said like 2 weeks ago.

You might have the caliper guide pins sliding really nice now but if they are worn at all and have a bit of play the caliper can still get stuck at some point in it's travel, especially when they heat up. Save yourself some time and headaches and just get a caliper exchange on both sides and new hoses.

TOKFLA · 12-14-2009, 11:38 AM

I am headed for the new hardware and weather permitting I will get it in ASAP. I feel as if you might be loosing patience. I know everything about these brakes now. (Humor) I am getting there.

Here is the breakdown: The right side is still dragging and pulling about the same. The caliper and hose on the right have been replaced. There are 2 lines that come out of the master cylinder; one is for the front and one for the rear drums. The one for the front disks goes to a small splitter close by and the line for the left front disk goes directly from that. The one for the right disk goes to the mechanism whose name I should know but do not and the rear line goes there as well. The 2 lines for the rear exit from this and the line for the right front does too. This mechanism sits at the front center of the firewall. I presume it is messed up somehow as I think it balances between the front and rear. I guess I am going to have to remove and clean it as it is maintaining the pressure on the right front while the left front manages to relax. I cannot see anything else that could cause a problem. Everything will have to be bled following. Any suggestions? I would take a picture of this but did not. What is this little distributional piece of plumbing called? I will get this problem sooner or later. Sorry I do not know all the right words. On and on. Whatever input is appreciated.
