How to Change the Brake Pads in a Mercedes E300 DT

1. Loosen the lug nuts on each of the front wheels with the lug nut wrench. Do not remove them completely.
2. Place the jack under the front end of your Mercedes under the center part of the frame. Jack the end of the car up enough so you can get the jack stands under each side behind the tires. Lower the car onto the stands carefully. This will ensure your car won't fall if the jack fails.
3. Remove the lug nuts of one wheel and pull the tire off the axle. Unscrew the bolt holding the caliper to the brake pads. Gently set down the caliper to avoid damaging the brake line.
4. Put on the gloves and mask to avoid exposure to the brake pad dust. Remove the two old brake pads from the rotor. Apply the C-clamp to the brake piston to retract it. This will reset the brake system since you are installing new pads.
5. Clip the new brake pads in place with the caliper. Remove the C-clamp from the piston. Tighten the caliper bolts to keep the new brake pads in place.
6. Slide the wheel back onto the axle and replace the lug nuts. Repeat the same process on the other side. Then raise the car to remove the jack stands and release the jack to lower the car back to the ground. Fully tighten the lug nuts with the lug nut wrench.
7. Loosen the lug nuts on the rear tires of your Mercedes. Place the jack under the center of the rear end under its frame and jack it up. Place the jack stands behind the wheels and lower the car onto the stands. Repeat the steps to replace the rear brake pads.
