Same old - Same Old ---> Squeaky brakes

Discussion in 'General Motoring' started by Watashi.wa.ichiban, Apr 21, 2006.

  1. 1998 V70- 100,000 miles

    Squeaky brake(s)(?) so had new pads installed & rotors machined by
    non-Volvo shop.
    Next day still squeaky - back to shop, supposedly fix, no squeaking

    One weeks later minor squeak started which now is at a life-threatening
    level. Can't & wouldn't take it back to old shop.

    Additional info:
    Sounds like passenger side is louder

    Only starts to squeak after driving 1-2 miles & brake pedal in use,
    then only continuous when pressure applied to brake pedal - something
    heating uP?

    ABS & track light was on - fixed by dealer two weeks BEFORE squeak
    started - cause and effect?

    Is it true that the V70 had a stabilizer recall? Could the stailizer
    cause squeaking from forward pressure when brakes applied?

    I'm not exactly sure what your problem is, but on my 1998 V70XC
    (basically the same model) the brakes have been emmiting more of a
    low-pitched "hum"-ish noise for about the last 80,000 miles...pretty
    much forever. After talking to my mechainic a few times and the dealer
    at a free diagonostic clinic, I have found a striking conclusion:

    With Volvo's commitment to safety, they are using bigger and bigger
    braking systems, especially on the super-safe V70s. However, a normal
    driver does not need anything close to that sort of power in day-to-day
    driving. With these modern braking systems, a sort of cleaning system
    is built in to eliminate road dirt, which can cause squeals and squeaks
    unneccessarily. However, for that cleaning system to work the brakes
    must heat up to burn off that road dirt -- and for such heating to
    occur, they have to be applied near maximum power. It's kind of dumb,
    isn't it?

    So the only way I've found to clear my squeaks and clean my brakes is
    once a month, I take it to a large open parking lot, accelerate as
    rapidly as I can, and then slam on the brakes all the way. It must look
    kind of funny from outside the car, but it works.

    Many aftermarket pads are noisy on certain Volvos. Personally I had
    good results with Raybestos QuiteStop pads on my 850. I also had good
    results with Volvo OE pads. Some other aftermarket pads were very noisy.

    Most non-Volvo shops will install the cheapest pads they can get, which
    almost always means noise!

  5. This is true. To make brakes quiet, car manufacturers spend a lot of
    time matching the pads to the metal on the discs. It is not trivial. It
    is not a one size fits all solution. The car manufacturers want a pad
    that lasts, but to increase sales and customer satisfaction, they put a
    big priority on having a quiet combination. If you use after-market
    brake rotors, the pads you use will need to match that rotor. Volvo
    pads may not be the best match in that case.
