Installation Guide
Installation of brake components requires mechanical knowledge and specialized tools. If you are not confident in your ability to perform this installation, it is highly recommended to seek assistance from a certified automotive technician.
General Steps (Consult Vehicle Service Manual for Specifics):
- Preparation: Park the vehicle on a level surface, engage the parking brake, and block the wheels. Loosen lug nuts on the rear wheels.
- Lift and Secure: Safely lift the rear of the vehicle using a jack and support it with jack stands. Remove the rear wheels.
- Drum Removal: Carefully remove the brake drum. This may require tapping with a rubber mallet or using a drum puller if it's seized.
- Inspect Components: Inspect the existing brake hardware (springs, adjusters, retainers) for wear or damage. It is often recommended to replace brake hardware when replacing shoes.
- Remove Old Shoes: Disconnect the parking brake cable and carefully remove the old brake shoes and springs. Note the orientation of all components for reassembly.
- Clean and Lubricate: Clean the backing plate thoroughly. Apply a thin layer of high-temperature brake lubricant to contact points on the backing plate where the shoes slide.
- Install New Shoes: Install the new Power Stop Autospecialty Parking Brake Shoes, ensuring all springs, retainers, and the parking brake lever are correctly attached.
- Adjuster Assembly: Reassemble and adjust the brake shoe adjuster mechanism.
- Drum Reinstallation: Reinstall the brake drum. Ensure it slides on freely without excessive force.
- Final Assembly: Reinstall the wheels, lower the vehicle, and tighten lug nuts to manufacturer specifications.
- Brake Adjustment: Pump the brake pedal several times to seat the shoes. Adjust the parking brake cable tension if necessary, following your vehicle's service manual.
Important: Always refer to your vehicle's specific service manual for detailed, step-by-step instructions and torque specifications.
Operating Considerations
After installation, it is crucial to properly "bed-in" your new brake shoes to achieve optimal performance and longevity. This process helps transfer a layer of friction material from the pads to the brake drum, ensuring consistent braking.
Bed-In Procedure:
- Find a safe, open area with minimal traffic.
- Accelerate to approximately 35 mph (56 km/h).
- Apply the brakes moderately (not aggressively) to slow down to about 5 mph (8 km/h). Do not come to a complete stop.
- Repeat this process 5-6 times, allowing a short cool-down period between each stop.
- After the last stop, drive for several minutes without using the brakes to allow them to cool completely.
During the bed-in process, you may notice some smoke or a burning smell. This is normal. Avoid hard braking or prolonged heavy use immediately after installation.
Maintenance
Regular inspection of your parking brake shoes is vital for safety and performance. It is recommended to inspect them during routine tire rotations or other brake system maintenance.
Inspection Points:
- Friction Material Thickness: Check the thickness of the friction material. If it is worn down to 3mm or less, replacement is recommended.
- Uneven Wear: Look for signs of uneven wear across the shoe surface, which could indicate issues with the drum, wheel cylinder, or hardware.
- Cracks or Damage: Inspect for any cracks, chips, or other damage to the friction material or the shoe backing plate.
- Hardware Condition: Ensure all springs, clips, and adjusters are in good condition and properly installed.

Troubleshooting
If you experience issues with your parking brake system after installing new shoes, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|

| Squealing/Grinding Noise | Improper installation, contaminated shoes, worn drums, missing anti-squeal shims (if applicable). | Re-inspect installation. Clean shoes and drums. Replace drums if worn. Ensure all components are clean and properly lubricated. |
| Excessive Pedal Travel | Air in brake lines, improper shoe adjustment, worn master cylinder. | Bleed brake system. Adjust brake shoes. Consult a technician for master cylinder inspection. |
For persistent issues, consult a qualified automotive professional.
