Installation Guide

The following step‑by‑step instructions outline the typical process for installing the KS635 Kit Super Pro. While the kit is pre‑assembled, proper alignment and torque specifications are critical to achieving optimal performance.

1. Preparation: Secure the vehicle on a flat surface using jack stands. Remove the rear wheels and access the drum brake assembly.
2. Remove Existing Components: Carefully detach the old brake shoes, backing plates, and springs from the drum. Keep all hardware in order for re‑use or disposal.
3. Inspect Drum: Check the drum for signs of wear, scoring, or damage. Replace if necessary to ensure a smooth braking surface.
4. Install New Backing Plate: Position the new backing plate onto the drum, aligning it with the mounting holes. Secure using the supplied bolts and nuts.
5. Attach Brake Shoes: Slide each brake shoe into its designated slot on the backing plate. Ensure that the shoes are seated evenly and free of obstructions.
6. Install Springs: Place the springs onto the shoe assembly, following the manufacturer’s recommended orientation to maintain proper pressure distribution.
7. Reattach Wheel Cylinder: Fit the wheel cylinder into its mounting position. Tighten all fasteners to the specified torque values.
8. Check Alignment: Verify that the shoes are correctly aligned with the drum and that there is no binding or excessive clearance.
9. Reinstall Wheel: Place the wheel back onto the hub, secure it with lug nuts, and lower the vehicle to the ground.
10. Brake Bleed: Perform a brake fluid bleed to remove any air from the hydraulic system. This step is essential for maintaining consistent braking feel.
11. Test Drive: Conduct a short test drive at low speed, checking for proper brake engagement and ensuring there are no abnormal noises or vibrations.

Maintenance Tips

• Regularly inspect the brake shoes for wear. Replace them before they become too thin to maintain effective braking.
• Check the backing plates for cracks or deformation, especially after heavy usage or exposure to extreme temperatures.
• Ensure that all hardware remains tight and free from corrosion. Re‑torque bolts if necessary.
• Keep the brake fluid reservoir topped up with the recommended type of fluid to prevent contamination and maintain hydraulic integrity.
