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.

Piston
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.
Check piston surface for corrosion, wear and damage. If corrosion, wear or damage is detected, replace the
applicable part.
Sliding Pin, Pin Bolt, and Pin Boot
Check sliding pin and sliding pin boot for wear, damage and cracks. If corrosion, wear or damage is detected,
replace the applicable part.
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks and serious damage. If uneven wear, cracks or serious
damage is detected, replace it.
Run Out Inspection
1. Using wheel nuts, fix disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check run out.
NOTE:
Make sure that wheel bearing axial endplay is with in the specifi-
cations before measuring runout. Refer to FAX-7, "
On-Vehicle
Inspection" .
3. If the run out is outside the limit, find the minimum run out point
by shifting the mounting positions of disc rotor and wheel hub by one hole.
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If the thickness is
outside the standard, replace the disc rotor.
ASSEMBLY
CAUTION:
When assembling, do not use rubber grease.
1. Apply rubber lubricant to piston seals, and install them to cylin-
der body.
CAUTION:
Do not reuse piston seals.Measurement point:
At a point of 10 mm (0.39 in) from the outer edge of
the disc.
Run out limit : 0.04 mm (0.0016 in) or less
BRA0013D
Standard thickness : 28.0 mm (1.102 in)
Wear limit : 26.0 mm (1.024 in)
Maximum uneven wear (measured at 8 positions):
0.02 mm (0.0008 in) or less

2. Apply brake fluid or rubber lubricant to piston boots. Cover pis-
ton end with piston boot. Install cylinder side boot lip properly
into groove on cylinder body.
CAUTION:
Do not reuse piston boot.
3. Apply brake fluid to piston. Press piston into cylinder body by
hand. Assemble piston side boot lip properly into groove on pis-
ton.
CAUTION:
Press piston evenly and change pressing point to prevent
cylinder inner wall from being rubbed.
BRAKE BURNISHING PROCEDURE
Burnish the brake pad contact surfaces according to the following procedure after refinishing or replacing
drums or rotors, after replacing pads or linings, 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 vehicle on a straight smooth road at 50 km/h (31 MPH).
2. Use medium brake pedal/foot effort to bring 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 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.

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.

PAD WEAR INSPECTION
Check pad thickness by lifting vehicle, removing tyre and wheel, and
looking through check hole on cylinder body. If necessary, use a
scale.

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,
and shims.
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. Install pad retainers to torque member and install pads.
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.
