Inspection after Removal
Lining Thickness Inspection
^ Check thickness of lining.

Wear limit thickness (A) Refer to [Service Data and Specifications]
Drum Inner Diameter Inspection
^ Check drum inner diameter.
Standard inner diameter Refer to [Service Data and Specifications]
Wear limit of inner diameter Refer to [Service Data and Specifications]
Other Inspections
^ Check shoe sliding surface for excessive wear and damage.
^ Check anti-rattle pin for excessive wear and corrosion.
^ Check return spring for sagging.
^ Check adjuster for rough operation.
^ When disassembling adjuster, apply PBC (Poly Butyl Cuprysil) grease or equivalent to the adjuster threads. Refer to [Recommended Fluids and Lubricants] (North America), [Recommended Fluids and Lubricants] (Mexico).

NOTE:
After replacing brake shoes or disc rotors, or if parking brake does not function well, perform break-in operation as follows.
1) Adjust parking brake lever stroke.
2) Perform parking brake burnishing operation by driving the vehicle forward under the following conditions:
^ Vehicle speed 40 km/h (25 MPH) set (forward)
^ Parking brake operating force 196-245 N (20.0-25.0 kg-f, 44.1-55.1 lb-ft) set
^ Apply time 10 sec.
CAUTION:
^ To prevent lining from getting too hot, allow a cool off period of approximately 5 minutes after every break-in operation.
^ Do not perform excessive break-in operations, because it may cause uneven or early wear of lining.
3) After burnishing operation, check parking brake lever stroke. Readjust if it is now longer than the specified stroke. Refer to [Parking Brake System: On-Vehicle Service].
