I have a 1997 Aurca 3.0 cl, I get a bad vibration in the brake peddle, and can hear a rotation noise when I turn right - the vribration is not there untill I drive the car for awhile - in other words if brakes are cool no vribration, warm or hot I get vribration. Brakes were replaced 12 months ago.
Do you

Have the brakes looked at again, sounds like a classic brake pulsation, also get a complete front end inspection to look for worn/bad front end compontents.

NOT THE ANSWER I WAS LOOKING FOR! HOPEING FOR SOMETHING A LITTLE MORE TECHNICAL - IT IS NOT A CLASSIC BRAKE PULSATION (REREAD MY DETAILS). NOT REALLY HAPPY WITH YOUR FEEDBACK, MAYBE ANOTHER TECH SHOULD TAKE A SHOT AT MY QUESTION, PROTECH1980

I'd give it a shot but my answer would be exactly the same. What else do you think brake pedal pulsations come from, the wipers? Being a brake expert, I notice every little detail about my minivan, and mine went from a perfectly smooth pedal to a pulsation so horrendous I can hardly stand to drive it, in less than two weeks. My brakes are about 8 years old but that warpage didn't show up for almost that long.

If you want technical, have the rotors checked for lateral runout. You may have a caliper sliding back and forth setting up the rotational noise you're hearing. Have them checked for thickness variation. That will cause the pedal to pulse up and down. Have the back side checked for the development of huge rust spots. They can make noise with or without pedal pulsations. Why expect PROTECH1980 to know what's wrong over a computer? If you want some obscure technical answer you gotta provide more details other than the standard, common symptoms you listed. Sheesh! Anyone with the least bit of courtesy would simply say, "I think it's something else. What other things can I check?" Many problems take many replies with lots of questions and suggestions before we arrive at a solution. Most of the experts will stick with you until the problem is resolved, ... If you treat us with the tiniest amount of respect.

Turn off your capital locks, and lets try to solve the problem regardless HOW many replies it takes. And don't expect us to be psychic. We're really not that good. You are to blame if you don't like the answer because you didn't provide any information that would lead any normal person to think it's anything other than a warped rotor. Give us details if this is no ordinary problem.

Thanks for the backup guys, I was answering the question to the best of my knowledge, with the details given. Sorry my crystal ball is broken that allows me to hear and feel vibrations many miles away.

Tee hee hee. They gotta hold their keyboard closer to the car. Or is it the mouse? I get those two mixed up.
