Rear Brake Noise

Not %100 sure, but it sounds like a loose brake caliper, or if equipped with rear drum brakes, it could be one or more of the many components involved with holding the brake shoes in place, and one more possibility of being a broken brake pad or shoe. Can you tell where it's coming form? The front, rear or possibly the center which would point more towards drive train issues....

Time for shocks and struts.

The rear suspension has no drive parts as your car is a FWD, front wheel drive. There are parts on the wheel axles which have bearings and also Brakes.
If you have rear disc brakes, the inner part of the rotor has a drum for Emergency brakes and these linings often peel off their brake shoe. The loose lining can get ground up in the turning rotor hub. The Emergency brakes are pinned to the brake backing plate and can clunk when the shoes shift. If you have rear drum brakes the shoes may be out of adjustment or worn out leaving room to rock as vehicle direction changes.
Bearings, excess play can cause noise. Suspension brackets, bushings within the mounts for these components can wear out. When parts are moving in 1 direction a "set" is grooved into the rubber parts. Changing direction of travel will unseat the part and make noise.
Traveling sound. You may be hearing a sound you suspect is in the rear of the car, but is actually a cradle mount around the Firewall. Sound travels through metal.
You need to get the rear wheels off the ground and check for play in all the components. For the cradle mounts, have someone ride the brake pedal and shift the transmission forward and backward to see if noise is generated or excess play is seen.

You have a seized caliper.

A scraping sound is more likely to be worn brake pads. The sound is an indication that very soon, there will be metal shoe to disc / drum contact. When this happens, the cost of the brake work can increase substantially. The parking brake makes use of the rear brake disk / drum and can also be the source for this noise.

Have the brakes inspected at once to lower the cost of the work if warranted. The stopping distance will increase slightly if the rear brakes have work out (the vast majority of braking needed to stop a vehicle is performed by the front brakes). The parking brake my not "hold" the vehicle if worn out.

It is also possible that while inspectimng the brakes that the service provider may be able to tell you the problem (if not brakes) during a road test or inspection.

I hope this helps & good luck!

My first question would be have you taken the drums off and looked at the brake shoes yet ?
You won't know whats going on until you do.
It could be worn out shoes, or a broken spring rubbing the drum, or any number of things.

Sounds like one of the springs that hold the rear brakes in place broke. Jack her up, pop off the tire, remove the drum and take a look. If you need to see what a good one looks like, look on the other side.

This is not a very common problem, but I saw it last year on a 69 chevelle.

Good Luck and thanks for using FixYa!!

It sounds like the rear shoes have come loose inside the drum. If this has happened it could cause serious damage and cause your brakes to lock up on you causing a wreck.

The grinding noise in the rear brake drum means that brake shoes are warn out and the metal part of the shoe is touching the drum. You need to replace it asap as it will damage the inner part of the drum and than replacing shoes will not help without skimming or replacing the drum.
