2. Apply rubber grease to piston boot. Cover the piston end withpiston boot, and install cylinder side lip on piston boot properly
into groove on cylinder body.
CAUTION:
Do not reuse piston boot.
3. Apply brake fluid to piston, and press piston into cylinder body by hand to assemble piston side lip on piston boot properly into
groove on piston.
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. Install the torque member to the knuckle spindle and tighten the mounting bolts to the specified torque. Refer to BR-18, "
Compo-
nent".
CAUTION:
Before installing torque member to vehicle, wipe oil and
grease on the washer seats on steering knuckle and the
mounting surface of the torque member.
6. Install pad retainers to torque member.
7. After assembling shims and shim covers to pad, install it to torque member.
CAUTION:
Inner pad and outer pad have pad-return mechanism on the
upper side of the pad retainer. When installing pad, be sure to install pad return lever to pad wear
sensor securely as shown in the figure.
8. Install cylinder body, and tighten sliding pin bolt to specified torque. Refer to BR-18, "
Component".
9. Install a projection of brake hose metal fitting by aligning with protrusions on cylinder body, and then tighten union bolts to specified torque. Refer to BR-10, "
Hydraulic Circuit".
CAUTION:
 Assemble brake hose securely to protrusions on cylinder body.
 Do not reuse copper washer for union bolts.
10. After installing caliper assembly, refill with new brake fluid and bleed air. Refer to BR-8, "
Bleeding Brake
System".
