We have 2017 GLC300 with 40k miles. Rear brakes completely worn and need replacing and dealer quote $700 but the fronts look new yet. How can rears be in such bad shape and fronts be in such great shape? Anyone else have similar?
The only reason I can think of would be that the parking brake is not releasing properly, are the discs worn evenly ? My neighbour had a similar problem with a VW Tiguan it was cured with new discs and pads but we never could work out the cause of the problem.
If it helps, you seem to be doing ok.
We replaced our front discs and pads and rear pads at 42,000km, not miles.
Told I did really well, told rear discs have around another 5 to 8000km left in them, then they will fit new rear discs.
Brake wear much heavier in GLC, I put it down to using adaptive cruise control all the time.
Let us know how you go with rear pads and discs.
I got 21k miles from my rear pads, dealer and MB UK not interested. Took it to an MB specialist who said handbrake not realesing properly would likely contribute. In them i paid them £100 to stick some decent pads in as i wont have it in another 21k sonit wasnt worth the fight with MB.
My GLC43 in the USA got 17K before the rear pads were worn. I took it to my MB specialist who noted the pads were worn but the rotors were ok. I did not ask if the parking break was an issue. The cost was around $300. I am starting to think the GLC43 is just high maintenance on tires, brakes, etc.
Had rear pads replaced at about 45k km, front ones still had about 40% left. I think the reason is that the stability control uses rear brake pads a lot more than front ones and you may not even feel it. Sticky handbrake would have caused wear much sooner.
I experienced this problem on a BMW 5 Series, basically in my circumstances it was the cruise control braking on the rear discs that caused excessive wear. Do you use your cruise control a lot ?
I have the same problem on my wife's 2017 GLC300, rear break finished at 28km, just 2 month after the 2 year warrenty. dealer won't change it for free. , dealer did not tell us there is rear brake issue at the 2nd year service.
still 80% left on the front.
Does anyone else think this rear brake pad issue is linked to crosswind assist "feature"? Rear brakes should never go before fronts
Interpreting information that is continually supplied by the vehicle's Electronic Stability Program (ESP®), electric power steering and suspension sensors, Crosswind Assist helps detect the effects of strong side winds on handling stability at highway speeds. Whether caused by lateral gusts or even a passing truck, the system helps keep the car on course via strategic braking of the wheels on one side of the vehicle, as well as adjustments to the AIR BODY CONTROL suspension when so equipped.
Just a thought. I'm still under 10,000 miles, but I'll be watching.
