XC90 squeaky brake advice
Discussion
My MY12 XC90 has developed squeaky brakes when braking.
We got the car from a volvo dealer at the beginning of the year with 16k miles on it.
It went for a service in September having done 20k miles. I was advised that the discs might need replacing due to lack of use.
I took the car to the dealer last week to look at the squeaky brakes. Paid £90 for all the pads and discs to be cleaned up, the squeaks are less, but it is still very apparent. Was told that I might need new discs and pads all round if it persisted.
I have had plenty of cars and never been told that I need new discs because of lack of use. The car has been used frequently for the school run, hence low mileage, maybe stood for a week or so maximum at a time when we have been away.
Any advice greatly appreciated.

Lack of use? that's a new one me!We got the car from a volvo dealer at the beginning of the year with 16k miles on it.

Firstly, I'm really skeptical of so-called main dealers (or stealers), times are hard and they're trying to make a living like everybody else.
If the pads aren't worn or rotten, and the disk isn't warped, the only real cause of a squeak would be a lump of grit gotten into the friction lining. Usually, this goes away after a while. There's the possibility that you have Pagid pads and disks which are known to squeal some times but I doubt that's the problem.
If the squeal starts to drive you mad, replace the pads (don't get the stealer to do it, it's an easy job) I got a set of Mintex pads for mine (I have XC90 front brakes on my V70) for 45 quid or so, and they've been fine.

Thanks Martin, I agree, I don't buy the 'lack of use' either. I'll take it to a local indy and see if they can give them a check.Firstly, I'm really skeptical of so-called main dealers (or stealers), times are hard and they're trying to make a living like everybody else.

How long has the squeak been happening? a good bit of grit can last for weeks before it goes or scores the disk enough to quiet down a bit.martinrpeachey said:

A number of weeks now, maybe couple of months. The squeaking got less when the dealer took the wheels off and gave the pads and discs a clean, but I'm just not convinced they did much for their money. The car was very dirty when I took it in and they didn't clean it for me (said the valet was off sick) and I didn't see any of the tell tale clean areas where the wheels would have been handled, maybe I'm just being cynical?Squeaking brakes can also be from a lack of copperslip applied to the rear of the pads- the pad squeaks as it oscillates and rubs on the disc and caliper.
Normally this stops when you brake but it can persist.
Also if the discs have a "lip" around them then that can squeak on the pads until it wears a groove in the pad - check the discs for a lip.
Also - have you bedded your pads in properly - green pads (new) can make squeaky noises until they are properly bedded in - particularly if you only change the pad, as it has to shape to the disc which will not have a flat surface as its not a new disc.
"Break In
IMPORTANT: BREAK IN NEW BRAKE PADS/ROTORS USING THE PAD BEDDING PROCEDURE AS FOLLOWS. PROPER PAD BEDDING CAN PREVENT ROTOR WARPING.
The break in procedure is critical to brake performance. The reason for a proper break in is to establish an even layer of friction material deposited on the rotors from the brake pads. It is very important that this initial layer of friction material is evenly distributed. Break in the pads as follows: 5 or 6 moderate to aggressive stops from 40 mph down to 10 mph in rapid succession without letting the brakes cool and do not come to a complete stop. Then do 5 or 6 moderate stops from 35 mph to 5 mph in rapid succession without letting the brakes cool. You should expect to smell some resin as the brakes get hot. After this is complete, drive around for as long as possible without excessively heating the brakes and without coming to a complete stop (Try for about 5 minutes at moderate speed). This is the cooling stage. It allows the heated resin in the brake pads to cool and cure. After the brakes have cooled to standard operating temperature, you may use the brakes normally"
