4. Attach the pad retainers and pads to the torque member.
5. Push the piston in so that the pad is firmly attached and attach the cylinder body to the torque member.
NOTE:
Using a disc brake piston tool (commercial service tool), makes it easier to push in the piston.
CAUTION:
By pushing in the piston, the brake fluid returns to the master cylinder reservoir tank. Watch the
level of the surface of the reservoir tank.
6. Install the sliding pin bolt and tighten to the specification. Refer to BR-27, "
Component".
7. Inspect brake fluid level, then install master cylinder reservoir cap.
8. Check brake for drag.
9. Attach the tires to the vehicle. Refer to WT-6, "
Rotation".
CAUTION:
Burnish the brake contact surfaces when refinishing or replacing brake rotors, after replacing
pads or linings, or if a soft pedal occurs at very low mileage. Refer to BR-29, "
Brake Burnishing".

Brake Burnishing".
Brake BurnishingINFOID:0000000001724670
Burnish the brake contact surface according to the following procedure after refinishing or replacing rotors,
after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).
2. Use medium brake pedal /foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH).
Adjust brake pedal /foot pressure such that vehicle stopping time equals 3 to 5 seconds.
3. To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.

2. Using a pin-punch [commercial service tool: diameter approx. 4
mm (0.16 in)], remove pin from reservoir tank.
3. Remove master cylinder assembly from vise.
4. Remove reservoir tank and grommet from cylinder body.
5. While pushing primary piston, remove piston stopper through
secondary tank boss hole in the cylinder body.
6. Remove snap ring with pushing primary piston.
CAUTION:
Be careful not to pop out piston.
7. Holding rod of primary piston, remove primary piston assembly,
plate and guide assembly by pulling straight to prevent piston
cup from being caught by the inner wall of cylinder.
8. Remove plate and guide assembly from primary piston.
CAUTION:
Be careful not to damage rod from the inner wall of plate.
9. Tap flange using a soft block such as wood, and carefully pull
secondary piston assembly straight out to prevent cylinder inner
wall from being damaged.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of cylinder for damage, wear, corrosion, and pin holes. Replace cylinder body if neces-
sary.
ASSEMBLY
CAUTION:
Never use mineral oils such as kerosene or gasoline during the cleaning and assembly processes.
Make sure that there is no foreign material such as dirt and dust on the inner wall of cylinder, piston,
and piston cup. Be careful not to damage parts with a service tool when assembling.
Do not drop parts. If a part is dropped, do not use it.
