Technical Specifications

Performance Characteristics

The caliper’s design ensures a uniform pad pressure distribution across the brake disc, reducing uneven wear and enhancing braking efficiency. Its cast grey iron body provides superior thermal conductivity, allowing heat to spread quickly and preventing brake fade during prolonged use.

Installation Guide

1. Preparation: Verify that the vehicle’s front‑wheel assembly is clean and free of debris. Inspect the disc for damage or excessive wear.
2. Mounting: Align the caliper with the mounting holes on the wheel hub. Secure using the supplied bolts, tightening to the manufacturer’s torque specifications.
3. Piston Alignment: Ensure the piston is seated correctly within the caliper housing. Use a feeler gauge to confirm proper clearance.
4. Brake Pad Installation: Place new brake pads into the caliper, ensuring they sit flush against the disc surface.
5. Bleeding: Bleed the braking system according to vehicle service procedures to remove air pockets and achieve optimal hydraulic pressure.

Troubleshooting Common Issues

• Uneven Pad Wear: Check for misalignment of the caliper or uneven disc surface. Re‑align if necessary.
• Brake Noise: Inspect pads and discs for glazing or contamination. Replace components as needed.
• Reduced Braking Force: Verify hydraulic fluid level and ensure no leaks in the caliper seal.

Maintenance Recommendations

Regular inspection of the brake system is essential to maintain safety and performance. Follow these guidelines:

• Periodic Inspection: Check pad thickness every 10,000 km or as recommended by vehicle service intervals.
• Seal Integrity: Inspect piston seals for signs of wear or leakage during routine maintenance checks.
• Disc Condition: Look for scoring, warping, or excessive rust on the brake disc surface. Replace discs if damage exceeds manufacturer limits.
