Front Brake (For Hatchback) -- Inspection |
| 1. INSPECT BRAKE CYLINDER AND PISTON |
Check the cylinder bore and piston for rust and scoring.
If necessary, replace the disc brake cylinder and piston.
| 2. INSPECT PAD LINING THICKNESS |
Using a ruler, measure the pad lining thickness.
Text in Illustration *1 Ruler - Standard thickness:
- 12.0 mm (0.472 in.)
- Minimum thickness:
- 1.0 mm (0.0394 in.)
 |
| 3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE |
Make sure that the disc brake pad supports have sufficient rebound, that there is no deformation, cracking or wear, and that all rust and dirt are removed.
If necessary, replace the disc brake pad support plate.
| 4. INSPECT DISC THICKNESS |
Using a micrometer, measure the disc thickness.
Text in Illustration *1 Micrometer - Standard thickness:
- 22.0 mm (0.866 in.)
- Minimum thickness:
- 19.0 mm (0.748 in.)
 |
| 5. INSPECT DISC RUNOUT |
Check the bearing play in the axial direction and check for the axle hub runout (YARIS_NCP93 RM000001IWW03ZX_01_0017.html).
Tighten the disc with the 4 nuts.
- Torque:
- 103 N*m{1050 kgf*cm, 76 ft.*lbf}
Using a dial indicator, measure the disc runout 10 mm (0.394 in.) away from the outer edge of the front disc.
Text in Illustration *1 Dial Indicator - Maximum disc runout:
- 0.05 mm (0.00197 in.)
