Installation Instructions

These are general guidelines. Always refer to your vehicle's specific service manual for detailed instructions and torque specifications.

1. Preparation: Park the vehicle on a level surface, engage the parking brake, and block the wheels. Loosen lug nuts, then raise the vehicle and secure it with jack stands. Remove the wheel and tire assembly.
2. Drum Removal: Carefully remove the brake drum. If it is stuck, use a rubber mallet or a drum puller.
3. Inspection: Inspect all existing brake components for wear, damage, or corrosion. Take photos or make a diagram of the existing hardware arrangement before disassembly.
4. Old Hardware Removal: Using appropriate brake tools (e.g., brake spring pliers, hold-down spring tool), carefully remove the old springs, clips, pins, and other hardware components. Note the position and orientation of each part.
5. Cleaning: Clean the backing plate and other brake components thoroughly with an approved brake cleaner. Do not use compressed air.
6. New Hardware Installation: Install the new Carlson H1338-2 hardware components, matching them to the positions of the old parts. Ensure all springs are correctly tensioned and all clips and pins are securely seated. Pay close attention to the parking brake strut springs if included in the kit, as these are often specific.
7. Reassembly: Reinstall the brake drum, ensuring it slides on smoothly. Reinstall the wheel and tire assembly, then lower the vehicle. Torque lug nuts to manufacturer specifications.
8. Brake Adjustment & Testing: Adjust the parking brake if necessary. Pump the brake pedal several times to ensure proper shoe adjustment and firm pedal feel before driving. Test the brakes in a safe area at low speed.

Maintenance

Regular inspection of your drum brake hardware is essential for safety and performance.

• Periodic Inspection: During routine brake service or tire rotations, inspect all drum brake hardware for signs of wear, corrosion, stretching, or breakage.
• Lubrication: Apply a thin coat of high-temperature brake lubricant to contact points between the brake shoes and backing plate, as well as any moving parts (excluding friction surfaces).
• Replacement: It is generally recommended to replace drum brake hardware whenever brake shoes are replaced, as springs and clips can lose tension or corrode over time.

Troubleshooting Common Issues

If you experience issues after installing new hardware, consider the following:

• Squealing/Grinding Noise: May indicate improper installation of springs, worn brake shoes, or contamination. Re-inspect hardware and shoes.
• Weak Parking Brake: Could be due to incorrect parking brake strut spring installation or improper adjustment.
• Uneven Braking: Ensure all components are installed correctly on both sides of the vehicle and that brake shoes are properly adjusted.
• Loose Pedal: After installation, pump the brake pedal several times to allow the self-adjusters to set the shoes. If the pedal remains loose, check for air in the hydraulic system or other brake component issues.
