BRAKE BOOSTER

INSPECTION AFTER REMOVAL
Output rod length inspection
1. Using a handy vacuum pump, apply a vacuum of -66.7 kPa (-500 mmHg, -19.69 inHg) to the brake
booster.
2. Check output rod length.
3.
INSTALLATION
1. Loosen lock nut to adjust input rod length so that length “B” (in
the figure) satisfies the specified value.
2. After adjusting “B”, temporarily tighten lock nut to install booster
assembly to vehicle.
3. Connect brake pedal to input rod clevis.
4. Connect brake pedal assembly mounting nuts and tighten to the
specified torque.
5. Connect master cylinder to booster assembly.
6. Adjust brake pedal height and play.
7. Tighten input rod lock nut to the specified torque.
8. Bleed air. Refer to BR-9, "
Bleeding Brake System" . Reference value at vacuum of –66.7 kPa (–500 mmHg,
–19.69 inHg):
Without ESP models : 10.4 mm (0.409 in)
With ESP models : -6.2 mm (-0.244 in)

ComponentEFS000CG
WARNING:

Clean brake pads with a vacuum dust collector to minimize the hazard of airborne particles or
other materials.
CAUTION:

When cylinder body is open, do not depress brake pedal because piston will pop out.

Be careful not to damage piston boot or spill brake fluid oil on rotor. Always replace shims when
replacing pads.

If shims are rusted or show peeling of the rubber coat, replace them with new shims.

It is not necessary to remove torque member mounting bolt and brake hose union bolt except for
disassembly or replacement of caliper assembly. In this case, suspend cylinder body with wire so
as not to stretch brake hose.

Burnish the brake pad contact surfaces after refinishing or replacing drums or rotors, after replac-
ing pads or linings, or if a soft pedal occurs at very low mileage. Refer to BR-31, "
BRAKE BUR-
NISHING PROCEDURE" .

Pad ReplacementEFS000CI
REMOVAL
CAUTION:
When replacing brake pads, always replace inner shims, outer shims, and shim covers as a set.
1. Remove master cylinder reservoir tank cap.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers,
shims and pad return springs.
INSTALLATION
1. Apply brake grease on back of the pad and both sides of the shim. Install inner shim and inner shim cover
to inner pad, outer shim to outer pad.
2. Apply brake grease on a pad sliding part of pad retainer. Install pad retainers, pads and pad return springs
to torque member.
3. Connect cylinder body to torque member.
CAUTION:
When replacing pads with new ones, press piston in until the pads can be installed. Carefully mon-
itor brake master cylinder reservoir fluid level. Brake fluid will return, raising master cylinder res-
ervoir tank fluid level.
4. Insert lower sliding pin bolt and tighten to the specified torque.
5. Check brakes for drag.
Caliper Removal and InstallationEFS000CJ
REMOVAL
1. Connect a vinyl tube to bleed valve.
2. Drain brake fluid gradually from bleed valve while depressing brake pedal.
3. Remove union bolts and torque member mounting bolts, and
remove caliper assembly.
4. Remove disc rotor.

INSTALLATION
CAUTION:

Refill with new brake fluid “DOT 3” or “DOT 4”.

Never reuse drained brake fluid.
1. Install disc rotor.
2. Install caliper assembly. Tighten mounting bolts to the specified torque.
CAUTION:
Before installing caliper assembly, wipe brake fluid and grease on steering knuckle washer seats
and caliper assembly mounting surface.
3. Connect brake hose to caliper assembly and tighten union bolts to the specified torque.
CAUTION:

Do not reuse copper washer for union bolts.

Securely assemble brake hose to protrusions on cylinder body.
4. Bleed air. Refer to BR-9, "
Bleeding Brake System" .

DISASSEMBLY
WARNING:
Be careful not to pinch your fingers in the piston.
CAUTION:
Be careful not to damage the cylinder inner wall.
1. Place a wooden block as shown in the figure. Blow air into union
bolt mounting hole to remove pistons and piston boots.
2. Using flat-bladed screwdriver, remove piston seals.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.

Check cylinder inner wall for corrosion, wear and damage. If corrosion, wear or damage is detected,
replace the cylinder body.

Minor flaws caused by corrosion or foreign material can be removed by polishing the surface with fine
sandpaper. Replace the cylinder body, if necessary.
To r q u e M e m b e r
Check for wear, cracks and damage. If wear, cracks or damage is detected, replace the applicable part.

WARNING:

Clean dust on brake caliper and pad with a vacuum dust collector. Do not blow with compressed
air.
CAUTION:

Never depress brake pedal while removing cylinder body because piston will pop out.

Do not remove brake hose and torque member mounting bolts unless disassembling or replacing
caliper assembly. Hang the cylinder body with a wire so that the brake hose is not under tension.

Be careful not to damage piston boot. Do not allow brake fluid to get the rotor.

When replacing brake pads, always replace inner shims, outer shims, and shim covers as a set.
