Knowing that the bi-annual technical safety inspection for my -89 240 was due in a few months, I changed all 4 rotors and bought 4 new rebuilt calipers, everything from my local Volvo dealer to be sure that everything was going to be perfect. The job was easy and fast (even bleeding went smoothly), and my brakes have been superb ever since. I have only driven 1000-1500 miles with the car after the brake renovation though.

Today, my car was in for inspection, and the only thing that they found was that both front calipers were "sweating", i.e. no leak as I have seen no signs of brake fluid in my garage nor any need to refill fluid, but as they said "moist where the ntwo halves are joined together". Have not been under the car yet to check on the findings, but I have compiled all my receipts intending to claim my Volvo dealer for the parts.

Has anyone else experienced the same with rebuilt calipers?
