Ford Taurus Brake Noise Q. I have found your web site to be very informative and feel that you can help me with a problem that we have been experiencing with our Taurus for about 3 years. The vehicle is 1997 Ford Taurus 4 Dr. LX. 24 valve Duratec 3.0 liter engine. The vehicle has automatic transmission, FI, and 46,666 miles.

The dealer has changed brake pads and turned the rotors, replaced rear hub, rotors, drive axle?, and load sensing proportioning valve. They also said they replaced the calipers but this was not listed on any of the invoices.

The problem began when the vehicle had over 20,000 odometer miles. The dealer put on brake pads and turned the rotors (no sound before this). The brakes began making a rubbing sound (and some vibration) especially, when making left turns and in some instances when going straight.

When making a left turn and the noise is present, lightly touching the brakes causes the noise to cease. The sound is periodic indicating an association with the rotation of the wheels. Also, the sound is dull, not indicating a metal to metal contact sound.

The vehicle was in the shop several times and they replaced different parts (see above) saying the problem was fixed and each time the noise immediately returned. I have replaced both rear brake pads and rotors as well as measuring the flatness of the rotors (they were within 2 thousands of an inch). We have given up with the dealer because they just can't solve the problem.

Any help that you can give me would be appreciated.
Thanks,
Fred

A. This is a tough one Fred. The dealer seems to have done all the things I could have suggested. And from what you describe, it does seem to be coming from the brake pads.

There is always a slight pressure on the brake pads so that much is normal. I would have to look at the brake pad friction material as a possible cause. You might want to try a set of aftermarket brake pads that may have less metal content then the Ford brake pads.

When you put the new pads on, put a good coating of white lithium grease or a coating of CRC Anti-Squeal between the pad backs and the anti-squeal shims. This will help isolate any noise that may be caused due to the friction material.
