Parking Brake Inspection
WARNING: This page is about a different car, the 2008 Acura TL and 2007 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
- Avoid breathing dust particles.
- Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.
- Raise the rear of the vehicle, and support it with safety stands in the proper locations (see LIFT AND SUPPORT POINTS ).
- Remove the rear wheels.
- Release the parking brake, and remove the rear brake caliper and brake disc/drum (see REAR BRAKE DISC REPLACEMENT ).
- Check the parking brake linings (A) for cracking, glazing, wear, and contamination.
- Measure the parking brake lining thickness (B). Measurement does not include brake shoe thickness.
Parking brake lining thickness:
Standard: 2.5 mm (0.098 in.)
Service limit: 1.0 mm (0.04 in.)
- If the parking brake lining thickness is less than the service limit, replace all of the parking brake shoes as a set.
- Check the hub bearing unit (C) for smooth operation. If it requires servicing, replace the hub bearing unit (see HUB REPLACEMENT ).
- Measure the inside diameter of the parking brake drum with inside vernier calipers.
Parking brake drum inside diameter:
Standard: 169.9-170.0 mm (6.689-6.693 in.)
Service limit: 171.0 mm (6.732 in.)
- If the inside diameter of the parking brake drum is more than service limit, replace the brake disc/drum.
- Check the parking brake disc/drum for scoring, grooves, and cracks.
- Clean the mating surfaces of the brake disc/drum and the inside of the wheel, then install the rear wheels.
