Installation Guide (Overview)

1. Preparation: Ensure the vehicle is securely lifted and supported on jack stands. Disconnect the battery for safety.
2. Remove Existing Caliper: Detach brake lines, remove caliper mounting bolts, and carefully slide out the old caliper.
3. Install ABS 428632: Position the new caliper onto the mounting bracket. Tighten bolts to manufacturer torque specifications.
4. Brake Line Reconnection: Reattach brake lines, ensuring no leaks. Bleed the braking system to remove air pockets.
5. Final Checks: Verify proper pad alignment and test brake function before road use.

Performance Benefits

The ABS 428632 enhances overall vehicle safety by providing:

• Improved Stopping Distance: Even pressure distribution reduces the distance required to bring the vehicle to a complete stop.
• Reduced Brake Fade: Efficient heat dissipation maintains braking performance during extended use.
• Consistent Pad Wear: Symmetrical piston action promotes uniform pad wear, extending component life.

Maintenance & Care Recommendations

To preserve optimal functionality, adhere to the following maintenance practices:

• Inspect brake pads and rotors every 10,000 miles or as recommended by the vehicle manufacturer.
• Check caliper mounting bolts for tightness during routine service intervals.
• Use high‑quality brake fluid compatible with ABS systems; replace according to schedule.
• Avoid exposure to corrosive environments that could compromise metal integrity.
