| 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 26, Driveshaft ).
| 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. After re-installing the caliper support to the knuckle, install the pad clips and the pads to the caliper support.
| 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 bolt.
| >>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: <Except for 2000-DOHC>: 68 N or less <Vehicle for 2000-DOHC>: 77 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.
