calipers drag abs light on 1993 LeSabre

RE: calipers drag abs light on 1993 LeSabre
I agree with Rupe that it really looks like a caliper issue. I am going to guess it’s the pads. My reasoning here starts with the fact that you have changed almost everything. It’s not out of the question, but unlikely that those new parts are sticking. Second, I have personally seen it several times now. I have had to remove the thin metal or fiber shim on the back side of the brake pad to get the wheels to spin freely. Look at your pads and see if they have a removable shim on the back. If so, I’d try that as your next step. If you do, please let us know what happens!

ok
I bought it all from the auto parts store with the cap on the delivery truck.. Thought i bought the best product.

Was going to buy a proportion valve next. guess I will just keep spitting on the wheel for a while..
Thanks for all the advice and your time.

Don't go with the proportioning valve. That has nothing to do with your problem.

The point Garner was trying to make is that extra shim might make the pad too thick and cause the pads to drag. The key here would have been that things were hard to assemble and you'd have to force the caliper on.

If the caliper went on easy then I would be asking if the pistons were hard to push back or if the sliding hardware was sticky. Things should move firmly but smoothly. If you had to use a crow bar to push the pistons back then that's a clue. The sliders can usually be moved by a firm finger push.

The ceramic pads I bought from Napa were so thick they barely fit. After about 800 miles of smelly heat I bought another set from pep boys that were thinner and made of standard material. The new rotors looked glazed then so I sanded them with emery paper. The new pads did help some. I had to use a big c clamp to push in the pistons for the second set of pads.
Maybe the ceramic pads ruined my calipers. Pads I have on now are thin and getting thinner.
Thanks again for your assitance.

All things being equal (and ok) ceramic pads should not ruin anything but do require slightly higher pedal effort and do last a bit longer.

Still in all, many aftermarket pads do not fit right and tend to hang up. Over the years I have seen some that fit so tighly in the caliper that I have had to take a file to the edges or sandpaper to the friction surface, and that's after making sure there's no rust or scale on the mating caliper surface.

Give things a few days to settle in then post again to let us know how this is working out for you. It may help others with similar problems.

RE: calipers drag abs light on 1993 LeSabre
OK, I had another thought. Since nothing seems to make sense I tried to think of what else could cause heat in the brake area besides what we have already discussed. The only thing that came to mind was the Wheel Bearings. You also said that the ABS light came on. A bad Wheel Bearing can turn the ABS light on. So; for the fifty million dollar question, “Did anyone check the Wheel Bearings?” I know that’s a long shot but I’m grasping for straws right now. Sometimes we get our mind so set on one thing that we don’t look any further. There might be other things too but that’s all that I can come up with right now.

Wheel bearings have never been replaced. 195,000 mileage. To check them out I jacked the wheel off the ground and grasp the tire on the top and bottom and wiggled back and forth hard. No movement felt firm. No noise.
Again I am no expert. I will do this again with tire off.
Thanks

Thanks

RE: calipers drag abs light on 1993 LeSabre
You did it the right way. With the tire ON you get much more leverage and can feel if it is moving. You also said that there isn’t any noise. A bad wheel bearing usually starts out as a rumble and progresses to a screech while driving.

Thanks for the update. I’ll keep thinking.
