How to Change Brake Pads on a Mercedes

The brakes on a Mercedes-Benz, like on any other car, are integral to safety. For this reason alone, keep an eye on brake pad wear and change brake pads when necessary. Change your Mercedes' brake pads when they are 1/8 inch thick, or when you notice steering wheel vibration when stopping.

Instructions

1

Turn the lug nuts 1/4 of a turn on all the wheels, using a tire wrench.

2

Jack up the Mercedes using the front jack point. This is in the front of the vehicle, normally located near the radiator.

3

Place jack stands under the frame of the Mercedes and lower the vehicle onto the jack stands.

4

Loosen the lug nuts all the way and remove the wheel. Start with the driver's side and work your way around the vehicle (order of brake replacement is not important).

5

Unbolt the top and bottom caliper bolt and remove them using the Torx wrench. The Torx wrench is a wrench with a "star"-shaped end instead of a standard socket end. Turn counterclockwise to loosen the Torx bolts.

6

Life the caliper up and secure it to the coil springs with zip ties.

7

Slide the pads out.

8

Place the face of the old brake pad over the caliper piston. Then, place the c-clamp over the brake pad and caliper and force the piston back into the caliper housing by tightening the pad to the caliper piston. Make sure that the piston boot folds accordion-style back into the caliper housing.

9

Insert the new pads in the same orientation as the old pads, reassemble the caliper and brake assembly and put the wheels and lug nuts back on. Assembly is the reverse of dis-assembly.

10

Repeat steps 4 - 9 for all wheels.

11

Lower the vehicle to the ground and torque the lug nuts to 100 ft-lbs using the torque wrench.
