Caliper Disassembly and Assembly
EFS000NR
DISASSEMBLY
1.
Remove caliper assembly from vehicle.
2.
Remove sliding pins. Then remove pads, shims, and shim cov-
ers from caliper assembly, and remove pad retainers from cylin-
der body.
3.
Remove sliding pin boot from torque member.
4.
Using a flat-bladed screwdriver as shown in figure, remove
retaining ring from cylinder body.
5.
Place a wooden block as shown in figure, and blow air from
union bolt mounting hole to remove pistons and piston boots.
6.
Using a flat-bladed screwdriver, remove piston seals from cylin-
der body.
CAUTION:
Be careful not to damage inner wall of cylinder.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.
●
Check inner wall of cylinder for corrosion, wear, and damage. If a failure is detected, replace cylinder
body.
●
Minor flaws caused by corrosion or foreign material can be removed by polishing the surface with a fine
sandpaper. Replace cylinder body, if necessary.
Torque Member
Check for wear, cracks, and damage. If a malfunction is detected, replace applicable part.
Piston
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.
Check piston surface for corrosion, wear, and damage. If a malfunction is detected, replace applicable part.

REAR DISC BRAKE
Sliding Pin, Pin Bolt and Pin Boot
Check sliding pin and sliding pin boot for wear, damage, and cracks. If a malfunction is detected, replace appli-
cable part.
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If a malfunction is detected, replace
applicable part.
Run Out Inspection
1.
Using wheel nuts, fix the disc rotor to wheels hub. (2 or more positions)
2.
Using a dial indicator, check run out.
CAUTION:
Before measuring, make sure that axle end play is 0 mm.
3.
If run out is outside limit, find minimum run out point by shifting
mounting positions of disc rotor and wheel hub by one hole.
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side standard, replace disc rotor.
ASSEMBLY
1.
Apply brake fluid to piston seals and install them to cylinder
body.
CAUTION:
Do not reuse piston seals.
2.
Apply brake fluid to piston boots. Cover the piston end with pis-
ton boot, and install cylinder-side lip on piston boots properly
into groove on cylinder body.
CAUTION:
Do not reuse piston boot.
3.
Press piston into cylinder body by hand to assemble piston-side
lip on piston boot properly into groove on piston.
CAUTION:
Press the piston evenly and change the pressing point to
prevent inner wall of cylinder from being rubbed.

4.
Fix the piston boot with retaining ring.
CAUTION:
●
Make sure that boot is securely engaged in groove on
cylinder body.
●
Do not reuse retaining ring.
5.
Install sliding pins and sliding pin boots to torque member.
6.
Install torque member to axle assembly, and tighten mounting
bolts to the specified torque.
CAUTION:
Before installing torque member to axle assembly, wipe oil
and grease on washer seats on axle assembly and mount-
ing surface of torque member.
7.
Install pad retainers to torque member.
8.
After assembling shims and shim covers to pads, assemble it to torque member.
9.
Install cylinder body, and tighten sliding pin bolts to the specified torque.
10. Install brake hose to cylinder body and tighten union bolts to the specified torque.
CAUTION:
●
Assemble brake hose securely to protrusions on cylinder body.
●
Do not reuse copper washer on union bolt.
11. After installing caliper assembly, refill new brake fluid and bleed air.
