Technical Specifications

Installation Guide

The following steps outline a typical installation procedure for the ABS 521581 Brake Caliper on compatible vehicles:

1. Preparation: Secure the vehicle on jack stands and remove the wheel. Drain brake fluid if necessary.
2. Remove Old Caliper: Detach the caliper from the mounting bracket using a socket set, carefully disconnecting any hydraulic lines.
3. Install New Caliper: Position the ABS 521581 caliper onto the mounting bracket. Align the bolt holes and secure with the supplied hardware.
4. Re‑attach Hydraulic Lines: Connect the brake line to the new caliper, ensuring a tight seal.
5. Bleed Brakes: Follow manufacturer’s bleeding procedure to remove air from the system.
6. Test Drive: Verify proper braking response and inspect for leaks or abnormal noises.

Maintenance Recommendations

Regular maintenance extends the life of the ABS 521581 Brake Caliper. Follow these guidelines:

• Brake Fluid Check: Inspect fluid level and condition every 12,000 km or annually.
• Piston Inspection: Look for signs of wear or corrosion on the cast iron piston surface.
• Pad Wear Monitoring: Replace brake pads when thickness falls below manufacturer’s minimum threshold.
• Seal Integrity: Ensure all seals remain intact to prevent fluid leaks.
