Recently a commercial customer brought in a Sprinter that his guys had mentioned had braking issues on. When we stripped the brakes down, we were frankly shocked at our findings. Not only had the pads worn through to the metal but the discs had cracked from the excess wear. The problems also caused the calipers to fail as they had been too far extended and too hot in the use of the vehicle.
This turned out to be an expensive repair requiring new discs, pads, calipers and backing plates. Most of this could have been avoided by replacing the pads when they were worn. We always recommend regular servicing as we will always check your brake conditions.
Please take note. When driving, if you notice any deterioration in the braking ability of your vehicle, have the brakes looked at at the first opportunity. It could save a life.
