Maintance for GLB 250 2021 50,000 miles
My car has reached to 50000 miles . I usually change engine oil every 5000 - 7000 miles + new engine oil filter each time . Now my questions are Do I need to exchange the new engine coolant , brake fluid, brake pads or any other fluid of the rear front axle of 4Matic or components for my car at 50000 miles to make it better and last longer ? and my car also vibration a little bit on the driver's wheel side when using brake from the speed of 70 - 80 mph , The vibration will be disappeared if I drive my car for a long trip as > 150 miles or 3 hours driving and used brake much . So what is this problem ? . Thanks all for advising.
