5. When the repair work is completed, return the ignition switch to the
″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Brake System INFOID:0000000004305887
• Refill using recommended brake fluid. Refer to MA-14 .
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted surfac e of body. If brake fluid is splashed on painted surfaces
of body immediately wipe it off with cloth and then wash it away with water.
• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
• Use a flare nut wrench when removing a brake tube and use a flare nut torque wrench when installing a brake tube.
• When installing brake tubes and hoses, be sure to check torque.
• Before working, turn igniti on switch OFF and disconnect connec-
tors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
• Burnish the new braking surfaces after refinishing or replacing drums or rotors, after replacing p ads or linings, or if a soft pedal
occurs at very low mileage. Refer to BR-32, " Brake Burnishing
Procedure " .

REMOVAL
1. Remove front wheel and tire.
2. Secure the disc rotor using wheel nuts. CAUTION:
Put matching marks on wheel hub assembly and disc rotor,
if it is necessary to remove the disc rotor.
3. Drain brake fluid. Refer to BR-9, " Drain and Refill " .
4. Remove the union bolt (A) and discard the copper washers. Remove the brake hose from the cylinder body.
• Protusions (B)
CAUTION:
Do not reuse the copper washers AWFIA0502ZZ

2. Remove sliding pin bolts and remove cylinder body from the torque member. Remove pads, shims, pad return spring
(AD22VK) and pad retainers from torque member as necessary.
CAUTION:
When removing pad retainer fr om torque member, lift the
pad retainer in the direction shown by arrow, so as not to
deform it.
3. Remove sliding pins and sliding pin boots from torque member.
4. Place a wooden block as shown, and blow air from union bolt mounting hole to remove piston and piston boot.
CAUTION:
Do not get fingers caught in the piston.
5. Remove piston seal with a flat-bladed screwdriver. CAUTION:
Be careful not to damage the inner wall of cylinder.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of cylinder for corrosion, w ear, and damage. Replace cylinder body as necessary.
CAUTION:
Clean cylinder body using new brake fluid. Never use mineral oils such as gasoline or kerosene.
Torque Member
Check for wear, cracks, and damage. R eplace torque member as necessary.
Piston
Check piston surface for corrosion, wear, and damage. Replace piston as necessary.
CAUTION:
The piston sliding surface is plated . Do not polish with sandpaper.
Sliding Pin, Sliding Pin Bolt, and Sliding Pin Boot
Check sliding pins, sliding pin bolts and sliding pin boots for wear, damage, and cracks. Replace applicable
part as necessary.
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cr acks, and serious damage. Replace as necessary.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheels hub at two or more positions. SBR556E

2. Using a dial indicator, check runout.
CAUTION:
Make sure that wheel bearing axi al end play is within the
specifications before measuring runout. Refer to FAX-6," On-Vehicle Inspection and Service " .
3. If runout is outside the limit, find the minimum runout point by shifting the mounting positions of disc rotor and wheel hub by
one hole.
4. If runout is still out of the specific ation, grind rotor on-car using Tool until runout is within the specified limit.
Thickness Inspection Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specifications, replace disc rotor.
ASSEMBLY CAUTION:
When assembling, use only specified lubricant.
1. Apply rubber grease to new piston seal and install on cylinder body.
2. Apply rubber grease (CL25VF) or polyglycol ether based lubri- cant (AD22VK) to piston boot and apply brake fluid to piston.
Cover the piston end with piston boot, and install cylinder-side
lip on piston boot properly into groove on cylinder body. Runout limit
[measured at 10.0 mm (0.394
in) inside the disc edge] : Refer to

" Removal and Installation of Brake Pad " .
6. Install cylinder body to torque member.
7. Tighten sliding pin bolts to specified torque. Refer to BR-25, " Component " .
8. Install the caliper assembly. Refer to BR-28, " Removal and Installation of Brake Caliper Assembly " .
Brake Burnishing Procedure INFOID:0000000004305914
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 vehicl e 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.
