2. Apply brake fluid to piston, rubber grease to piston boot, then
install piston boot in to piston groove.
CAUTION:
Do not reuse piston boot.
3. Insert into cylinder body by hand and insert piston boot piston-side lip into piston groove. CAUTION:
Press piston evenly and vary the pressing point to prevent cylinder inner wall from being rubbed.
4. Install sliding pins and sliding pin boots to torque member.
5. Attach inner shim and inner shim cover to inner pad, and attach the outer shim to the outer pad.
6. Install cylinder body. Tighten sliding pin bolt to the specified torque.
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any of them is detected, replace
applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to wheel hub. (2 or more positions)
2. Inspect runout using a dial gauge. [Measured at 10 mm (0.39 in) inside the disc edge.]
NOTE:
Make sure that wheel bearing axial end play is within the specifi-
cations before measuring runout. Refer to FAX-4, "
On-Vehicle
Inspection and Service" .
3. If runout is outside the limit, find the minimum runout point by shifting mounting positions of disc rotor and wheel hub by one hole.
4. If runout is still out of specification, turn rotor with on-car brake lathe. (“MAD DL-8700”, “AMMCO 700 and 705” or equivalent.)
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the standard, replace disc rotor.

4. Fix piston boot with retaining ring.
CAUTION:

Make sure boot is firmly in cylinder body groove.

Do not reuse retaining ring.
5. Install sliding pin bolt and sliding pin boots to torque member.
6. Apply PBC (Poly Butyl Cuprysil) grease or silicon-based grease to the backside of pad and to both sides of shim, and attach inner shim and shim cover to inner pad, and the outer shim and outer shim cover to
outer pad.
7. Assembling shims and shim covers to pad. CAUTION:
When attaching pad retainer, attach it firmly so that it does
not float up higher than torque member, as shown in the fig-
ure.
8. Attach pad retainer and pad to torque member.
9. Install cylinder body. Tighten sliding pin bolts to the specified torque.
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any non-standard condition is
detected, replace applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to wheel hub. (2 or more positions)
2. Inspect runout using a dial gauge. [Measured at 10 mm (0.39 in) inside disk edge.]
NOTE:
Make sure that wheel bearing axial end play is within the specifi-
cation before measuring runout. Refer to RAX-5, "
On-Vehicle
Inspection and Service" .
3. If runout is outside the limit, find the minimum runout point by shifting mounting positions of disc rotor and wheel hub by one
hole.
4. If runout still out of specification, turn rotor with on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or equivalent).

7. Remove timing chain tensioner (secondary) from cylinder head.

Remove timing chain tensioner (secondary) with its stopper
pin attached.
NOTE:
Stopper pin was attached when timing chain (secondary) was
removed.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 4 jour- nals of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
three locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on a dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer.
2. If wear exceeds the limit, replace camshaft.
Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL DIAMETER

Measure the outer diameter of camshaft journal with a microme-
ter.
CAMSHAFT BRACKET INNER DIAMETER

Tighten camshaft bracket bolt with the specified torque. Refer to EM-89, "INSTALLATION" for the tighten-
ing procedure.
