  Q: How to replace the Brake Pad Set on disc brakes on Mercedes-Benz 300TD?

  A:

  Raise the vehicle and securely support it on jackstands before removing the wheels. Use needle nose pliers to unplug the wear sensor connectors if equipped. Remove the locking clips if present, then drive the upper retaining pin out with a small punch, followed by the removal of the retaining spring and the lower pin, pushing the brake pad anti-rattle spring down while withdrawing the pin. Grasp the ear of each pad with pliers and push the piston evenly into its bore to withdraw the pad, moving it side to side if necessary to dislodge any accumulated dust and dirt. Check each pad for wear, and if the lining thickness is below the minimum service limit, replace all disc pads on the axle involved. Clean the dust and dirt from the caliper housing, pistons, disc, and pads, scraping any corrosion or foreign material from the brake rotor, and measure the rotor thickness against the specifications. Draw out some fluid from the master cylinder reservoir to prevent overflow when pushing the caliper pistons back for the new pads, applying high melting-point brake grease to the contact surfaces of the back and edge of the new pad. Push each piston fully into its bore and insert the new pads into the caliper. Place the retaining spring on the pads and insert the pins, tapping them fully into the caliper while holding the brake pad anti-rattle spring down. Install any locking clips into the ends of the retaining pins and plug in the wear sensor wires. Finally, depress the brake pedal several times to seat the pads in their normal positions, and if a pressure differential warning indicator lights up after the installation, depress the reset pin on the master cylinder.
