Default Average miles before front brakes service ?

About how many miles have people been getting on Unitys before replacing front brakes and are they replacing rotors or turning them? I realize there are a lot of variables.

My first Sprinter camper went for about 60,000 before the fronts needed replaced and I don't think that they turn the rotors. I'm sure that this varies on how the campers are driven.

For the most part the OEM pads and rotors wear at a rate that precludes rotor resurfacing. By the time the pads are gone the rotors are too thin to turn. I believe that material wear is by design.

Some advice. I am cheap. I tried low priced rotors. They developed hard spots and voids before wearing out. Pay for good quality rotors. In my opinion OEM isn't the only choice, but they are good. Europarts SD offers good quality brake service kits, as do some other parts suppliers.

lonnie,
The materials used in OEM Sprinter brake pads and brake rotors have been selected so that
the pads and the rotors wear down at the same rate.
So, when the pads are down to the sensors, the rotors/discs are worn to the limit and need
to be replaced.
You can easily see (if you don't have the simulators that cover everything) the wear on the
rotors at the inner and outer areas at the edges of the rotor that is swept by the brake pads.
I can't answer your "front brakes on a Unity RV" question as I don't have a Unity RV, but I've
never had the front brakes replaced on any of the Sprinters (1 T1N.....4 NCV3's) and 3 of them
have had > 100k miles on the brakes.
My 2014 may be due for some brake work with 114,000 miles.
Many have tried alternative drilled rotors and high tech brake pads to stop the back rusty powder
that collects on the front wheels (it's brake rotor dust ground off the rotors by the very hard
brake pads) or some of them have changed to alternative (Non-OEM) rotors and pads in an attempt
change the overall Sprinter brake "feel" but for the most part I think these efforts have been
unsuccessful.
OEM replacement pads and rotors seem to be the most reliable, stop you in the shortest distance
and give you the longest brake life.
Hope this helps,
Roger

I know this is an old thread, but I was searching to see what kind of mileage people are getting out of their brakes and came across this thread and wanted to say thanks. Good info.

I had mine replaced at 78,544 miles .. both rotors and pads by MB dealer.
I do more long distance driving under speed control, so I do not have a lot of stop-go in city traffic.

Currently with 72,000 on our Unity TB we had the rear brakes replaced at 55,000 after the yearly PA inspection. We do many miles in the mountains, maybe 60 percent in the mountains. I asked the people at Sun Mercedes, a large dealer with a separate 8 bay sprinter only shop, why the rears. On cars and most vehicles it seems fronts need replacing first. They told me that the RV Sprinters are much harder on the rears then the front as are most trucks. A friend who was in charge of a large fire department maintenance shop also said that trucks, etc will always need the rears replaced before the fronts. Cars using mostly fronts to stop and trucks mostly the rears. We had the rears replaced at a cost of about $700 which included pads and rotors. In Pa we have a yearly inspection and up to now the front brakes still look good at 72k.
