Installation Guidelines

Proper installation of the ABS 521311 is critical to achieving optimal braking performance. Follow these steps for a successful fit:

1. Preparation: Ensure the vehicle’s brake system is depressurized and that all safety precautions are observed.
2. Removal of Old Caliper: Carefully detach the existing caliper, noting the position of the hydraulic line and retaining bolts.
3. Mounting the New Caliper: Align the mounting holes with the vehicle’s bracket. Secure using the supplied bolts, tightening to the manufacturer’s torque specifications.
4. Hydraulic Line Connection: Reconnect the brake line, ensuring a leak‑free seal. Bleed the system to remove air pockets.
5. Pad Installation: Insert new or existing pads into the caliper, making sure they are seated correctly against the piston.
6. Final Checks: Verify all fasteners, inspect for leaks, and perform a brake test at low speed before normal driving.

Maintenance Recommendations

To preserve the longevity of the ABS 521311 Brake Caliper, adhere to these maintenance practices:

• Regular Inspection: Check for signs of wear or corrosion on mounting points and pistons every 10,000 km.
• Brake Fluid Monitoring: Replace brake fluid according to the vehicle’s service schedule (typically every 2 years).
• Pad Replacement: Replace brake pads when pad thickness falls below 3 mm to prevent metal‑to‑metal contact with the rotor.
• Rotor Condition: Inspect rotors for scoring or glazing; replace if necessary to maintain optimal friction.

Applications Across Vehicle Models
