3. Clean the piston and insert into cylinder with special tool MB990520.

5. Check the brake drag force as follows.
1) Start the engine and hold the brake pedal down for 5 seconds. (Pedal depression force: approximately 196 N (44 lbs.))
2) Stop the engine.
3) Turn the brake disc forward 10 times.
4) Check the hub torque (B) with a spring scale.
5) Calculate the drag force of the disc brake [difference between hub torque (B) and hub torque (A)].
Standard value: 69 N (16 lbs.) or less
6. 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.
