Brake problem

[Boo34]

Need some help with this one. Front disc brake on passenger side will make a dragging noise at low speeds, around 15 mph. Turning left really brings out the best of this sound. When the brakes are applied the sound stops. Had both rotors turned. Still having sound. Rotors are not warpped. Help!!

2WD or 4WD? It sounds like your wheel bearing is loose.

replaced wheel bearings about month ago. I know they are tight. the truck is 2wd.

Could be your caliper is froze up and only one pad is releasing.

I agree with 1822. The caliper has to slide to apply or release pressure on the outer brake pad. Since it has a hydraulic assist to apply, it has to slide freely in order to release. The components that slide should be lubricated whenever serviced. My suggestion would be to remove the wheel and check the rotor on both sides and pad thickness on both sides. You may find a problem in how the rotor is wearing or if the outer pad is worn significantly more than the inner, the caliper is not sliding. Good luck!

If 1822 is correct, dont do what I did and use a high temperature anti size product on bolts and moving parts (every thing froze solid) use only specific silicon BRAKE grease.

good luck

It does sound like a brake problem with your turning but I have a '95 that started to make noise from that area after I had a brake job. It ended up being my carrier bearing on the tail shaft of the tranny. The noise would come and go. It was hard to track. Good luck-

Inner pad has really worn down. So now it must be the caliper is not releasing. Is there any way to make it? Please advise.

Boo34,
Something you might want to check is the flexible brake hose. I've had them be bad before and not let the calipher release. tpitt

The same thing happened to my old truck. Didn't catch it until it was too late. Had to have both the caliper, pads and rotor replaced. No turning of those big calipers! I used all OEM parts for the repair. Every thing seemed ok for a few weeks and then I realized that the truck pulled to that side when braking. Quickly got worse to the point of "unexpected lane change" every time I would brake. I assumed that it was stuck again. I pulled everything to check it out and could not find anything wrong. I bleed the brake system and it seemed ok until it warmed up, then the same symptom. Long story short, the other rotor and caliper had to be replaced to "match" the new one's stopping power. Local service shop said he has seen it often and knew just what it was. It got expensive and ugly. Glad I'm out of that money trap. Hope for the best and good luck. Dave

I had the same problem with my 92 and 96 Suburbans after doing my own brake jobs. I later learned that the caliper needs to be thoroughly cleaned and then silicon grease applied to the points where the inner pad contacts the caliper, where the caliper contacts the mounting brackets, and don't forget the slides on the bolts. Also make sure the inner pad does not bind in the caliper, if it does, buff it to remove the paint coating.

I found that using a small wire brush on my drill would buff the caliper to a shine. Becareful not to cut the seals around the cylinder.
