The Mercedes-Benz CLK-230 is a rear-wheel drive coupe/convertible based on the C-Class body style. Since the CLK series was introduced in 1992, all models come stock with 4 wheel anti-lock disc brakes, whick will occasionally need to be replaced. Changing the brake pads on a 1999 Mercedes CLK-230 requires some tool and mechanical experience.
Loosen the lugs on the wheels using a 1/2-inch ratchet wrench and lug socket. Place wheel blocks on the opposite end of the vehicle being lifted. Position a hydraulic lift under a structural body point and lift the vehicle. Use a pair of jack stands to secure the vehicle on each side, placing them under structure points.
Remove the lugs and place inside the wheel. Slide the wheel under the vehicle as close to the work area as possible for extra security. Remove the four retainer bolts holding the caliper to the wheel assembly using the Allen wrench set. Gently tap the caliper with the rubber mallet to remove from the rotor.
Use the C-clamp to push the caliper piston to its full open position while the original brake pads are still installed. Remove the original brake pads by prying the clips off the caliper unit with a screwdriver. Install the new brake pads by fitting them into place and prying the clip onto the indented spots of the caliper.
Place the caliper back into position over the rotor. Tighten each retention bolt to the specified torque. Reinstall the wheel and hand tighten the lugs. Remove the jack stands and lower the vehicle. Use the 1/2-inch ratchet wrench and lug socket to ensure each lug is tightened to the recommended torque. Enter the vehicle and press the brake pedal until it becomes stiff. Repeat for each wheel.
