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.

you must use volvo parts especially when it comes brake pads

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!

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.
