REMOVAL

1. REMOVE FRONT WHEEL

Remove the wheel and temporarily fasten the disc with hub nuts.

2. DISCONNECT FLEXIBLE HOSE

(a) Remove the union bolt and gasket from the caliper, then disconnect the flexible hose from the caliper. Torque: 30 N-m (310 kgf cm, 22 ftlbf)

HINT:

At the time of installation, install the flexible hose lock securely in the lock hole in the caliper.

(b) Use a container to catch the brake fluid as it drains out.

3. REMOVE CALIPER

(a) Hold the sliding pin and remove the 2 installation bolts. Torque: 34 N-m (350 kgf cm, 25 ft lbf)

(b) Remove the caliper from the torque plate.

4. REMOVE 2 PADS WITH ANTI-SQUEAL SHIMS

5. REMOVE 2 PAD SUPPORT PLATES

DISASSEMBLY

1. REMOVE SET RING AND CYLINDER BOOT

Using a screwdriver, remove the set ring and cylinder boot from the caliper.

2. REMOVE PISTON

(a) Place a piece of cioth or similar, between the piston and the caliper.

(b) Use compressed air to remove the piston from the cylinder

CAUTION:

Do not place your fingers in front of the piston when using compressed air.

3. REMOVE PISTON SEAL

Using a screwdriver, remove the piston seal from the cylinder.

4. REMOVE SLIDING PINS AND DUST BOOTS

(a) Remove the 2 sliding pins from the torque plate.

(b) 1ZZ-FE engine: Remove the 2 dust boots.

H0i677

Using a screwdriver and hammer, tap out the 2 dust boots.

HINT;

At the time of reassembly, use a 19 mm socket wrench and tap in 2 new dust boots into the torque plate.

NOTICE:

At the time of reassembly, check that the metai plate portion of the dust boot fits snugly in the torque plate.

INSPECTION

1. MEASURE PAD LINING THICKNESS

Using a ruler, measure the pad lining thickness. Standard thickness: 1ZZ-FE engine: 11.0 mm (0.433 in.) 2ZZ-GE engine: 11.5 mm (0.453 in.) Minimum thickness: 1.0 mm (0.039 in.) Replace the pad if the pad's thickness is at the minimum thickness or less, or if the pad has severe, uneven wear.

2. MEASURE DISC THICKNESS

Using a micrometer, measure the disc thickness. Standard thickness: 25.0 mm (0.984 in.) Minimum thickness: 23.0 mm (0.906 in.)

Replace the disc if the disc's thickness is at the minimum thickness or less. Replace the disc or grind it on a lathe if it is badly scored or worn unevenly.

3. MEASURE DISC RUNOUT

Using a dial indicator, measure the disc runout 10 mm (0.39 in.) away from the outer edge of the disc.

Maximum disc runout: 0.05 mm (0.0020 in.) If the disc's runout is maximum value or greater, check the bearing play in the axial direction and check the axle hub runout (See page SA-12). If the bearing play and axle hub runout are not abnormal, adjust the disc runout or grind it on a "On-car" brake lathe.

4. IF NECESSARY, ADJUST DISC RUNOUT

(a) Remove the 2 bolts and torque plate from the knuckle.

(b) Remove the hub nuts and the disc. Reinstall the disc in the position turned 1/5 from its original position on the hub. Install and torque the hub nuts.

Torque: 103 N-m (1,050 kgf-cm, 76 ft-lbf) Remeasure the disc runout. Make a note of the runout and the disc's position on the hub.

(c) Repeat (b) until the disc has been installed on the 3 remaining hub positions.

(d) If the minimum runout recorded in (b) and (c) is less than 0.05 mm (0.0020 in.}, install the disc in that position.

(e} If the minimum runout recorded in (b) and (c) is greater than 0.05 mm (0.0020 in.), replace the disc and repeat step 3.

(f) Install the torque plate and torque the mounting bolts. Torque: 107 Nm (1,090 kgf cm, 79 ft lbt)

REASSEMBLY

Reassembly is in the reverse order of disassembly (See page BR-23), NOTICE:

Apply lithium soap base glycol grease to the parts indicated by arrows (See page BR-20).

INSTALLATION

Installation Is in the reverse order oi removal (See page BR-22).

HINT:

Atter installation, fill the brake reservoir with brake fluid and bleed brake system (See page BR-4) • Check for leaks.
