Initial Inspection and Diagnostic Overview

Inspection and Verification
Check the operation of the parking brake system with the vehicle on a hoist and the parking brake control fully released. Check for any damaged cables and replace as necessary. Check the rear brake adjustment or perform brake system diagnosis.
Check the parking brake by depressing the parking brake control pedal. The parking brake must hold the vehicle on an incline, set by applying pressure to the pedal before it reaches full pedal travel to the floor. If not as specified, check the parking brake system for proper rear brake adjustment, cable operation and parking brake control operation.
