Operation and Leakage Check
Check all of the following items:
Component Procedure
Brake Booster (A) Check brake operation by applying the brakes during a test drive. If the brakes do not
work properly, check the brake booster. Replace the brake booster as an assembly if it
does not work properly or if there are signs of leakage.
Piston cup and pressure cup
inspection (B) a.
Check brake operation by applying the brakes. Look for damage or signs of fluid
leakage. Replace the master cylinder as an assembly if the pedal does not work
properly or if there is damage or signs of fluid leakage.
b. Check for a difference in brake pedal stroke between quick and slow brake
applications. Replace the master cylinder if there is a difference in pedal stroke.
Brake hoses (C) Look for damage or signs of fluid leakage. Replace the brake hose with a new one if it
is damaged or leaking.
Caliper piston seal and
piston boots (D) Check brake operation by applying the brakes.
Look for damage or signs of fluid leakage. If the pedal does not work properly, the
brakes drag, or there is damage or signs of fluid leakage, disassemble and inspect the
brake caliper. Replace the boots and seals with new ones whenever the brake caliper
is disassembled.
BRAKE BOOSTER OPERATING TEST
For simple checking of the brake booster operation, carry out the following tests
1. Run the engine for one or two minutes, and then stop it. If the pedal depresses fully the first time but gradually
becomes higher when depressed succeeding times, the booster is operating properly, if the pedal height remains
unchanged, thebooster is inoperative.

If you are reusing the pads, always reinstall the brake pads in their original positions to prevent a momentary
loss of braking efficiency.
3.Insert the piston in the cylinder using the special tool (09581- 11000).
4.Push in the piston (A) so that the caliper will fit over the pads. Make sure that the piston boot is in position to
prevent damaging it when pivoting the caliper down.
5. Being careful not to damage the pin boot, install the guide rod bolt (B) with the specified torque.
6.If caliper assembly was removed, install the brake hose to the caliper.
7. Refill the master cylinder reservoir to the MAX line.
8. Bleed the brake system.(Refer to 'Bleeding of ABS system')
9. Depress the brake pedal several times to make sure the brakes work, then test- drive.
Engagement of the brake may require a greater pedal stroke immediately after the brake pads have been
replaced as a set. Several applications of the brake will restore the normal pedal stroke.

4.Grease the piston boot to prevent from twisting.
5. Install the guide rod.
6. Install the cylinder assembly (A) to the disc plate.
Be careful not to damage the piston boot.
7.Install the guide rod bolt (B).
Tightening torque Nm(kgf.m,lb - ft) :
22 ~ 32 (2.2 ~ 3.2, 15.9 ~ 23.1)
INSPECTION
REAR BRAKE DISC THICKNESS CHECK
1. Remove all rust and contamination from the disc surface, and then measure the disc thickness at 8 points, al least,
of the same distance (5 mm(0.12 in)) from the brake disc outer circle.
Rear brake disc thickness
Standard value : 12.0 mm (0.47 in)
Limit : 10.4 mm (0.41 in)
2. Thickness variation should not exceed 0.01 mm(0.0004 in) (circumference) and 0.01 mm(0.0004 in) (radius) at any
directions.
3. If wear exceeds the limit, replace the discs and pad assembly for left and right of the vehicle.
