Great Info.. so from Napa $200 will get you premium equipment. And I would assume that the mechanic you went to was only changing one caliper. Ceramic pads are expensive... you could get lifetime pads for about $25-30 at most. Dropping total price to $170ish.

Do you have "fix-a-flat" in any of your tires? If so, then that is likely your problem. If not, then have you run your tires very low? If so, you may have internally "chewed" your tire which causes the rubber on the inside to "rub" off. Over time and high speed these small particles will actually collide with one another and join. This makes a bigger and heavier "ball".

The cycle continues until the "ball or balls" are so heavy that they throw the balance off.

This can not be corrected with a balance because the balls are always rolling.

Take off each tire and spin it by hand and listen for "rubber marbles" inside the tire.

I replaced the calipers, pads and rotors. I went around the block to test- 30mph firm braking 3 times like the book says. Then I went to a highway and tested for 70mph-80mph, and the bibration was minor but still there came and went. I believe whatever it is caused the caliper to break ( which it was the right one) and warp the rotor. So I put ceramic pads and performance calipers from NAPA Autoparts, and rotors as well. I guessing that over time they will break if I don't fix the problem... Any guess please.

Front Shocks???

I'll take ti to the tire place for a tire balancing and the manager offered a radio balancing...which is under guarantee.

Will see.

P.*.
I'll check for some marbles or balls rolling then.

In a way I fill very happy that I was able to change the rotors, pads and calipers of my Bonnie.

Thanx to all

How did your mechanic determine your right side caliper was not releasing in the first place?

Something is out of ballance. If it'* not the wheels and tires, the it must be the axles or rotors.

That is of corse if it is in the front end....Maybe the rear end is out of ballance?

How old are your tires? Most of the time vibration is tire related (out of balance, out of round, bent rim).

If you can find a shop that can do a spin balance with your tires on the car, they may be able to troubleshoot that vibration in their shop. I know they can run it at highway speeds by putting the tires on drums and firing it up. If they see the vibration, they will then try it without the tires. Then without the brakes. Process of elimination will eventually determine what is at fault. I had a simialr vibration a while ago and every tire shop that I took it to said it was tire balance. I am fairly confident wtih a wrench and like to think that I know what a warped rotor feels like. The good old boy that did this for me finally figured out that it was my performance rotors. He couldn;t believe it either. Just didn;t feel like a warped rotor. Anyway, he only charged about $60 for all that troubleshooting. The key is finding someone with the right equipment and patience.

BTW, did you clean and grease the caliper pins? Not sure if your year has disk or drum on the rear, but an out of round rear drum can also cause a vibration, but you feel it in your seat rather than steering wheel. You may have fixed the major vibration and have another minor one.

Good luck!
