1997 Volvo 850 Rear Brake Pad squeel

[STeve C]

Replaced my rear pads with Wearever Organic Disc Pads (Prt # D31) from
Advanced AutoParts. Terrible squeal when brakes applied was immediate.
Applied CRD Disc Brake Quiet without results. Re-applied with thicker coat,
with no effect. Squeal is as load as an ambulance siren. I will reinstall
old pads first chance to confirm the Pads are the culprit. Any other ideas,
perhaps another brand of pads?

My personal experience is that only GENUWINE Volvo pads don't squeel
on an 850. Also, use the dealer shims behind the pads. I think that's
the only 850 part I wouldn't cut corners on. Granted the dealers are
greedy but, in this case, I have found you have to yield to the
robbers.

Car manufacturers such as Volvo go to great lengths to find a rotor/pad
combination that has reasonable wear, reasonable performance and is
quiet. However, the combination is different for almost every
manufacturer of car and even different for some of their own makes.

What I am saying is that it is a miracle if they don't squeal. The only
way you can get original equipment performance is if you use original
equipment rotors and pads. If you change, you should change both the
rotors and pads and use proven combinations. The only proven
combination I know for a Volvo are the Volvo parts.

Did as you suggested, installed the shims along with a new mounting kit and
alls back to being well. For reference, Volvo part numbers 272272 and
217831 respectfully. Thanks again for the reply.
