OPERATING CHECK
With the engine stopped, change the vacuum to the atmospheric pressure by depressing brake pedal several
times at intervals of 5 seconds.
Then with brake pedal fully depressed, start engine and when the
vacuum pressure reaches the standard, make sure that the clear-
ance between brake pedal and floor panel decreases.
AIRTIGHT CHECK
 Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change the vacuum to the atmospheric pressure. Make sure that
distance between brake pedal and floor panel gradually increases.
 Depress the brake pedal while engine is running, then stop engine
with brake pedal depressed. The pedal stroke should not change
after holding pedal down for 30 seconds.

1. Loosen lock nut to adjust input rod length so that the length B
satisfies the specified value.
2. Install spacer to brake booster and tighten spacer nut (brake
booster side) to the specified torque.
3. After adjusting length “B”, temporarily tighten lock nut to install
brake booster assembly to dash panel. At this time, make sure
to install a gasket between brake booster and vehicle.
CAUTION:
Be sure to install the gasket between brake booster and
vehicle.
4. Connect brake pedal to clevis of input rod with the clevis pin and snap pin.
5. Install brake pedal bracket nuts and tighten them to the specified torque.
6. Adjust the height and play of brake pedal. Refer to BR-6, "
Inspection and Adjustment" .
7. Tighten lock nut of input rod to the specified torque. Refer to "COMPONENTS" .
8. Install vacuum hose into brake booster. Refer to BR-22, "
Removal and Installation" .
9. Bleed air from brake system. Refer to BR-8, "
Bleeding Brake System" . Length “B” : 154 - 161 mm (6.06 - 6.34 in)

CAUTION:
 Because vacuum hose contains a check valve, it must be installed in the correct orientation. Refer to
the stamp or label to confirm correct installation. Brake booster will not operate normally if hose is
installed in the wrong direction.
 Insert vacuum hose at least 24 mm (0.94 in).
 Never use lubricating oil during assembly.

CAUTION:
 Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed air.
 While removing brake pad or cylinder body, do not depress brake pedal because piston will pop out.
 It is not necessary to remove torque member mounting bolts and brake hose except for disassembly
or replacement of caliper assembly. In this case, hang cylinder body with a wire so that brake hose is
not under tension.
 Do not damage piston boot.
 If any shim is subject to serious corrosion, replace it with a new one.
 Keep rotor free from brake fluid.
 When replacing brake pad, replace shim with a new one.

2. Remove sliding pin bolt (lower side).
3. Hang cylinder body with a wire, and remove pads, shims and
pad retainers from torque member.
CAUTION:
When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow, so as not to
deform it.
INSTALLATION
1. Apply M-77 grease or equivalent to the shims. Install shims to pads.
CAUTION:
Securely install shims according to mounting direction of pads.
2. Apply M7439 grease or equivalent to pad contact surface on pad retainers. Install pad retainers and pads
to the torque member.
CAUTION:
 When installing pad retainer, attach it firmly so that it is
not lifted up from torque member, as shown.
3. Install cylinder body to torque member.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press to piston in.
CAUTION:
Check the brake fluid level in the reservoir tank for fluid level because brake fluid returns to mas-
ter cylinder reservoir tank when pressing piston in.
4. Install lower sliding pin bolt (lower side), and tighten it to the specified torque. Refer to BR-24, "
Compo-
nent" .
5. Check brake for drag.
6. Install tires to the vehicle.

Brake BurnishingINFOID:0000000001717009
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
 Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.
 Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
