This kit is sufficient to service one wheel assembly.
3. Setup and Installation
Safety Warning: Brake system work should only be performed by qualified personnel. Improper installation can lead to brake failure, resulting in serious injury or death. Always wear appropriate personal protective equipment (PPE) and follow all manufacturer guidelines.
Before beginning installation, ensure the trailer is securely supported on jack stands and the wheel is removed. Refer to your trailer's axle and brake system manual for specific torque specifications and additional safety precautions.
- Preparation: Ensure the trailer is on a level surface, chocked, and the parking brake is engaged. Lift the trailer and support it securely with jack stands. Remove the wheel and tire assembly.
- Caliper Removal: Carefully remove the brake caliper from its mounting bracket. This typically involves unbolting the caliper guide pins or mounting bolts. Do not let the caliper hang by the brake hose; support it to prevent damage to the hose.
- Old Pad Removal: Remove the old brake pads from the caliper. Note their orientation for correct installation of the new pads.
- Caliper Piston Retraction: Using a suitable caliper piston compression tool, slowly and evenly retract the caliper piston(s) into the caliper bore. This creates space for the new, thicker brake pads. Monitor the brake fluid reservoir to prevent overflow.
- New Pad Installation: Install the new AL-KO K71-866-00 brake pads into the caliper. Ensure they are seated correctly and match the orientation of the original pads. Apply a thin layer of high-temperature brake lubricant to the caliper guide pins and the back of the brake pads where they contact the caliper, if recommended by the caliper manufacturer.
- Caliper Reinstallation: Reinstall the brake caliper onto its mounting bracket. Tighten the caliper guide pins or mounting bolts to the manufacturer's specified torque.
- Brake System Bleeding (if necessary): If the brake lines were opened or air entered the system, bleed the hydraulic brake system according to the trailer manufacturer's instructions.
- Final Checks: Reinstall the wheel and tire assembly, tightening lug nuts to the specified torque. Lower the trailer. Before driving, pump the brake pedal several times to ensure the pads are seated against the rotor and a firm pedal feel is achieved. Check for any brake fluid leaks.
4. Operating Considerations
After installing new brake pads, a break-in period is recommended to ensure optimal performance and longevity. During this period, avoid heavy braking and allow the pads to gradually conform to the brake rotors. Follow the brake system manufacturer's recommendations for break-in procedures, which typically involve a series of moderate stops from varying speeds.
5. Maintenance
Regular inspection of your trailer's brake system is crucial for safety and performance. Inspect brake pads for wear, cracks, or damage at least annually, or more frequently depending on usage and towing conditions. Replace pads when they reach their minimum thickness specification, or if uneven wear is observed. Also, check brake rotors for excessive wear, scoring, or warping.
6. Troubleshooting
- Reduced Braking Performance: Check for air in the hydraulic system (bleed if necessary), worn pads, or contaminated pads/rotors.
- Brake Noise (Squealing/Grinding): Squealing can indicate worn pads, improper installation, or lack of anti-squeal shims/lubricant. Grinding typically indicates severely worn pads, requiring immediate replacement.
- Uneven Pad Wear: Can be caused by sticking caliper pistons, worn caliper guide pins, or warped rotors. Inspect and address the underlying cause.
- Soft Brake Pedal: Often indicates air in the hydraulic system, a leak, or a faulty master cylinder.
If you experience persistent brake issues, consult a qualified mechanic.
