How to Replace Front Brake Pads on a Mercedes C230

1. Park the C230 on a flat surface and apply the parking brake.
2. Place tire blocks behind the rear wheels.
3. Loosen the lug nuts on the Mercedes front wheels with the lug wrench.
4. Place the jack beneath the frame in the front of the vehicle and lift the front tires off the ground. Place two jack stands under the vehicle, one under each axle.
5. Remove the lug nuts and take the front wheels off.
6. Pull the spring clip from the outside of the caliper with a pair of pliers.
7. Remove the dust covers from the caliper slide bolts with a flat screwdriver. Remove both slide bolts on each caliper with a 14 mm socket wrench.
8. Lift the caliper from the caliper bridge and suspend it from the upper steering arm with a bungee cord or wire coat hanger--do not allow the caliper to hang by the brake line.
9. Open the brake bleed valve on the caliper with a 10 mm wrench. Place a drip pan below the caliper to capture the brake fluid that will flow from the bleed valve during the caliper piston depression.
10. Place the C-clamp over the piston and the back of the caliper. Squeeze the piston to force it into the side of the brake caliper. This will allow the caliper to fit over the new brake pads, which will be thicker than the outgoing, worn pads.
11. Remove the C-clamp from the caliper once the pistons have been completely depressed within the side of the caliper. Close the brake bleed valve with the 10 mm wrench. Dispose of the expelled brake fluid properly (see epa.gov for your states regulations on disposal of hazardous materials).
12. Remove the two brake pads from the slots of the caliper bracket.
13. Apply brake grease to the back side of each of the brake pads and slide them into the caliper bracket slots on either side of the Mercedes rotor.
14. Replace the caliper over the new brake pads in the caliper bracket slots and screw in the caliper bolts with the 14 mm socket wrench. Insert the spring clip back into the caliper.
15. Repeat the process (steps 6 through 14) for the other front brake pads.
16. Replace the front wheels onto the C230s wheel bolts and screw on the lug nuts.
17. Lift the front of the Mercedes and remove the jack stands. Lower the front tires to the ground and tighten the lug nuts with the lug wrench.

How to Replace the Front Brake Pads on a Mercedes 300 SE

1. Loosen the lug nuts on each front wheel slightly with the tire iron, turning them no more than 1/2 turn each. Firmly apply the parking brake. Slide the jack under the frame on one side of the front end and lift until the tire has cleared the ground. Unscrew the lug nuts the rest of the way and pull the wheel off.
2. Unbolt and the brake caliper with a socket wrench and remove it from the rotor. Hold it securely to prevent excess stress being placed on the brake line. Work a flat-head screwdriver behind the old pads and pry them out.
3. Place the new brake pads inside the caliper and press them all the way to the back of the housing. Make sure the tabs are firmly secured within the inset. Replace the caliper, tightening the bolts that were previously removed.
4. Reinstall the wheel and torque down the lug nuts. Lower the vehicle and finish tightening the lug nuts. Perform the same procedure on the other front wheel.
