I have never had brakes serviced over three Sprinters after 61,000, 65,000 and 95,000 miles and getting MB only service which everyone knows is costing us at a premium and if they had to be serviced you know they would gladly tell you. The 95,000 Sprinter was last serviced at the 80,000 interval but the last time I drove it, I noticed know need for brake service. I attribute that from only using our Class B Sprinters mostly on the highways with little need for braking for several miles as opposed to day to day city driving.
