Operating Instructions

Once installed, the Power Stop Autospecialty Parking Brake Shoes function as part of your vehicle's parking brake system. The parking brake is typically engaged via a hand lever or foot pedal inside the vehicle cabin.

Engaging the Parking Brake:

• Ensure the vehicle is stationary and in neutral (manual transmission) or park (automatic transmission).
• Apply the parking brake lever or pedal firmly until it is fully engaged. You should feel resistance and hear a clicking sound if it's a lever type.
• The parking brake indicator light on your dashboard should illuminate.

Disengaging the Parking Brake:

• For lever-type parking brakes, press the release button (if present) and lower the lever completely.
• For foot pedal-type parking brakes, press the pedal again or pull the release handle (depending on vehicle design).
• Ensure the parking brake indicator light on your dashboard is off before driving. Driving with the parking brake engaged can cause premature wear and damage to the brake shoes and system.

Maintenance

Proper maintenance of your parking brake system, including the brake shoes, is crucial for safety and longevity. While the Power Stop Autospecialty Parking Brake Shoes are designed for durability, regular inspection is recommended.

• Regular Inspection: Have your parking brake system inspected by a qualified technician during routine vehicle maintenance, typically every 12,000 to 15,000 miles or annually.
• Check for Wear: Technicians will check the thickness of the brake shoe lining and inspect for any signs of uneven wear, cracking, or damage.
• Hardware Inspection: Ensure all springs, adjusters, and other hardware components are clean, free of corrosion, and functioning correctly. Replace any worn or damaged hardware.
• Cable Adjustment: The parking brake cable tension may need periodic adjustment to ensure proper engagement and release.
• Keep Clean: Keep the brake drum area free from excessive dirt, dust, and debris, which can affect brake performance.
