Other Inspections

• Check the following:

• Lining for excessive wear, damage, and peeling.
• Shoe sliding surface for excessive wear and damage.
• Anti-rattle pin for excessive wear and corrosion.
• Return spring and adjuster spring for sagging.

• Make sure that adjuster moves smoothly.
• Visually check the inside of drum for excessive wear, cracks, and damage.

• Shorten adjuster by rotating it the opposite as shown
• Check parking brake shoe sliding surface and drum inner surface for grease. Wipe off all grease adhering to the friction surfaces.

ADJUSTMENT

After replacing the parking brake shoes or disc rotors, or if the parking brake does not function properly, perform the break-in operation as follows.

1. Adjust parking brake pedal stroke to the specified amount. Refer to PB-4, "On-Vehicle Service".
2. Perform parking brake break-in (drag run) operation by driving and performing the following steps:

• Drive forward at a constant speed of approximately 40 km/h (25 mph).
• Apply the parking brake for approximately 5 - 15 seconds at an operating force of approximately 150 - 199 N (15 - 20 kg, 34 - 45 lb).

CAUTION:

• To prevent lining from getting too hot, allow 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 break-in operation, check that the parking brake pedal stroke is at specification and adjust again as necessary. Refer to PB-4, "On-Vehicle Service".
