Precaution for Procedure without Cowl Top CoverINFOID:0000000003890162
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000003811170
WARNING:
Clean any dust from the front brake and rear brake with a vacuum dust collector. Never blow with com-
pressed air.
CAUTION:
 Only use “DOT 3 or DOT 4” brake fluid. Refer to MA-11, "
Fluids and Lubricants".
 Never reuse drained brake fluid.
 Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with water if it gets on a painted surface.
 Always clean with new brake fluid when cleaning the master cylinder, brake caliper and other com-
ponents.
 Never use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and
cause improper operation.
 Always loosen the brake tube flare nut with a flare nut wrench.
 Tighten the brake tube flare nut to the specified torque with
torque wrench (A).
 Always confirm the specified tightening torque when install-
ing the brake pipes.
 Turn the ignition switch OFF and disconnect the ABS actuator
and electric unit (control unit) connector or the battery nega-
tive terminal before performing the work.
 Check that no brake fluid leakage is present after replacing
the parts.
 Burnish the brake contact surfaces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage.
- Front brake pad: refer to BR-13, "
BRAKE PAD : Inspection and Adjustment".
- Front disc rotor: refer to BR-13, "
DISC ROTOR : Inspection and Adjustment".
- Rear brake pad: refer to BR-15, "
BRAKE PAD : Inspection and Adjustment".
- Rear disc rotor: refer to BR-15, "

BRAKE FLUID
2. Loosen the bleeder valve, slowly depress the brake pedal to the full stroke, and then release the pedal.
Repeat this operation at intervals of 2 or 3 seconds until all brake fluid is discharged. Then close the
bleeder valve with the brake pedal depressed. Repeat the same work on each wheel.
3. Perform the air bleeding. Refer to BR-10, "
Bleeding Brake System".
Bleeding Brake SystemINFOID:0000000003811176
CAUTION:
 Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-
nector or the battery negative terminal before performing the work.
 Monitor the fluid level in the sub tank during the air bleeding.
 Always use new brake fluid for refilling. Never reuse the drained brake fluid.
1. Connect a vinyl tube to the bleeder valve of the rear right brake.
2. Fully depress the brake pedal 4 to 5 times.
3. Loosen the bleeder valve and bleed air with the brake pedal depressed, and then quickly tighten the
bleeder valve.
4. Repeat steps 2 and 3 until all of the air is out of the brake line.
5. Tighten the bleeder valve to the specified torque.
 Front disc brake: refer to BR-34, "
BRAKE CALIPER ASSEMBLY : Exploded View".
 Rear disc brake: refer to BR-40, "
BRAKE CALIPER ASSEMBLY : Exploded View".
6. Perform steps 1 to 5 for the rear right brake → front left brake → rear left brake → and front right brake in
order.
7. Check that the fluid level in the sub tank is within the specified range after air bleeding. Refer to BR-9,
"Inspection".

INSPECTION AFTER REMOVAL
Output Rod Length Inspection
1. With a handy vacuum pump, apply vacuum pressure of −66.7
kPa (−500 mmHg, −19.70 inHg, –0.667 bar) to the brake
booster.
2. Check the output rod length (A).
Input Rod Length Inspection
1. Loosen the lock nut (1) and adjust the input rod (2) to the speci-
fied length (B).
2. Tighten the lock nut to the specified torque.
INSPECTION AFTER INSTALLATION
Operation
Depress the brake pedal several times at 5-second intervals with the
engine stopped. Start the engine with the brake pedal fully
depressed. Check that the clearance between brake pedal and dash
lower pane decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due to
the brake system operation.

1. Install the pad retainer to the torque member if the pad retainers has been removed.
CAUTION:
 Securely assemble the pad retainers so that it will not be lifted up from the torque member.
 Never deform the pad retainers.
2. Apply copper based brake grease to the mating faces between the brake pads and pad retainers.
3. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the mating faces between the brake
pads, shims and shim cover, and install them to the brake pad.
