| INSTALLATION SERVICE POINT
| >>A<< BRAKE CALIPER ASSEMBLY INSTALLATION In order to measure the brake drag torque, measure the hub torque with the pads removed by the following procedure. Remove the driveshaft <Refer to GROUP 27B, Driveshaft assembly (4WD)>.
| Attach special tool front hub remover and installer (MB990998) to the front hub assembly as shown in the illustration, and tighten it to the specified torque. Tightening torque: 245 ± 29 N·m
| Use a spring scale to measure the hub torque in the forward direction. Record hub torque with pads removed. CAUTION Do not let any oil, grease or other contamination get onto the friction surfaces of the pads and brake discs.
| Clean the piston and insert into cylinder with special tool disc brake piston expander (MB990520). Be careful that the piston boot does not become caught, when lowering the caliper assembly and installing the lock pin.
| >>B<< BRAKE DRAG FORCE CHECK Check the brake drag force as follows. Start the engine and hold the brake pedal down for 5 seconds. (Pedal depression force: approximately 200 N) Stop the engine. Turn the brake disc forward 10 times.
| Use a spring balance to measure the hub torque with pads installed in the same direction as earlier. Calculate the drag force of the disc brake [difference between hub torque with pads installed and hub torque with pads removed]. Standard value: 68 N or less If the brake drag force exceeds the standard value, disassemble and clean the piston. Check for corrosion or worn piston seal, and check the sliding condition of the lock pin and guide pin.
