Disk Rotor & Rear Drum Inspection
Brake disk thickness measurement
- Use a micrometer to inspect disk rotor thickness.
- Limit: 11.0mm (0.433 in)
- Replace below: 9.4mm (0.370 in)
Disk rotor run-out
- Use a dial gauge to check disk rotor run-out.
- Limit: below 0.08mm (0.003 in)
Note: check hub run-out before replacing the rotor.
Hub run-out
- Attach a dial gauge as shown. Inspect the hub for run-out.
- Limit: 0.05mm (0.002 in)
For repair or replacement, see the Driveline section of this manual.
Brake pad lining inspection (rear drum shoe)
- Measure lining thickness.
- Limit: 4.9mm (0.193 in)
- Replace: 1.0mm (0.039 in)
This measurement is for the rear drum brake shoe lining, distinct from the front disk pad thickness spec covered in Caliper Overhaul.
Brake drum diameter
- Measure brake drum diameter.
- Limit: 230.6mm (9.08 in)
- Replace below: 228.6mm (9.00 in)
Brake lining-to-drum inspection
- Place a brake shoe in the drum and rotate the drum. Check for surface binding. If binding occurs, have the drum cut or replace the drum.
