Help with Brakes

Got the Camaro out today to let her run for a little while. Started to pull back into the garage and slowly applied the brakes and heard and felt some weird noises. Almost a shuddering feeling. Definitely vibrations and not a rotor shimmying or brake pulsation situation. Didn't really feel anything weird in the pedal or in the steering wheel. I was only going a couple of miles an hour.
It felt like the front right wheel was on a piece of ice and was sliding. Went in reverse because I thought I ran over something and the noise did not occur when applying the brakes. Did this several times and it only happens when going forward. Don't know if its a front or back brake issue. Anyone have any idea here? Stuck caliper? Novice when it comes to brakes so be easy. TIA!

Re: Help with Brakes

Another attempt to describe this, brakes seem to grab with a slight vibration at low speeds. Not metallic or any squealing. Front rotors, rear drums.

Re: Help with Brakes

How old are the front brake hoses? Are you saying the brake on one side is acting like it doesnt release after applying pedal?

I do not know the age of any of the brake components.

It feels like it is occuring at the front right side and it occurs when pressing the brake pedal. After pedal is released, feeling and noise go away.

Re: Help with Brakes

Do you have drums or discs up front? I know you mentioned "caliper" in your first post, but looking at your signature, your car sounds fairly stock.

Just checking...

Yes, it originally started with drums but somewhere down the line the previous owner swapped the fronts to calipers.

Prior owner did not drive the car much and there could have been LONG period in which the car sat and did not drive. I assume that could affect the brakes potentially. Just adding more info.

Re: Help with Brakes

To help rule out the rear brake drums, try using the self-adjusting feature. Drive backwards and apply the brakes to a stop several times. You don't have to slam the brakes, just apply firm steady pressure until the car stops. This will help to insure your rear brakes are properly adjusted. If this doesn't help, there are many other things that could cause the symptoms you described. Try removing all wheels and the rear drims, inspect for leaks or fluids on the calipers, hose connections, discs, drums and pistons. Make sure all bolts are snug. Check your pad thickness and look for corrosion. Others may be able to provide some help as well.

Good luck, Mike.

Thanks Mike for the input. Will check into those.

Did want to post up a video so you can hear the sound. https://youtu.be/W5vz-vQ0uR8

Also it is definitely coming from the rear right side when the car is going forward. It does not occur when you go in reverse.

Re: Help with Brakes

Lift the front tire off that seems to have the brake issue, push the brake down hard and release, and then check to see if that tire turns. If it does not take a wrench and loosen the bleeder and re-tighten. If the wheel releases you have a collapsed rubber line to that wheel that will need to be replaced.

Re: Help with Brakes

When you get your drums off you will see a mess that looks something like this. It should be obvious if things are out of whack.

Good luck.

Re: Help with Brakes

Check the back side of the backing plate for fluid leaking. If you have a wheel cylinder or axle seal leak, it'll make the brake grabby at low speed.

Check my web page for First Gen Camaro suspension info:
