A while back I posted a problem about irregular braking pressure in my 02 S80. I could never figure it out. So I took it to this shop that my good friend take's her 1996 850 GLT to. The place is called Volvo Am I on 16th Street and Osborn. Let me tell you they are awesome there!!! Dirt cheep repairs, quality work, and there honest! They figured out my braking issue and it turned out to be a "brake pressure sensor". So if you live in the Phoenix metro area I highly recommend this shop! From oil changes to my drive axle that needed to be replace, they were and always will be the guys for the job! Thanks Alot Volvo Am I!
