Grinding noise coming from one of the rear wheels.

[layinthesmack31]

Hey guys lately i have noticed that sometime when i drive the car i hear this grinding noise that sounds like it is coming from on of the rear wheels. It doesnt do it all the time but it does stop as soon as i touch the brakes. I thought maybe wheel bearing but i heard that would do it all the time and mine will quit if i touch the brakes even a little. it is hard to diagnose the exact location beacuse i am in the car when it does it. Also the noise can be very quiet but then other times it is really loud and i just dont know where to start. Please any help would be greatly appreciated and if u need more info to help u let me know. thanks

Start by removing the suspected wheel. There is a possibility that the pads are worn down to the backing plate. Inspect the rotor surface (should be shiny and smooth).

I had all the pads ant rotors done about 4 months ago and the problem started about 2 months ago. i have checked the pads and rotors and they are good. The reason i had all the pads ant rotors done was because a caliper locked up and burned the pad off one of the rear brakes. But it didnt even make that noise when the caliper was locked up. This is like a metal on metal grind. Any ideas now? thanks for the quick response.

Sounds like you may have a stuck caliper of frozen pins even a sticking parking brake. Your pads could be worn out now and making this noise. This could also lower your gas mileage as indicated in your other thread.

Did you replace the rear brake hoses when you did the caliper?

I had a shop do the caliper so idk if they did or not what would be the problem with them? By the way no one thinks this could be the wheel bearing right? i just want to eliminate that from my list of options if u guys dont think that is what it is. By the way do any of u know where i can get a repair manual like the haynes of chiltons repair manuals. I cant seem to find one for a SHO anywhere. the normal taurus's i can but not the SHO. thanks again

The Chilton's I have covers SHO stuff as well - so if it says Taurus of the appropriate year then get it. Although I think I'd prefer a Haynes if I buy another one.

I dont' have any expereince with bad wheel bearings, but I'd be guessing if it goes away when you tap your brakes, then it's quite possibly a brake issue.
The flexable hoses that go to the rear caliper seem to fail at around 8-10 years old. They can collapse internally and hold pressure to the calipers, and still look just fine from the outside. ~$50 should do both sides.

Although when I had the same issue, it wasn't a grinding noise at all. Just a high pitched whine.

It might be that the shop used poor quality brake pads.....
