Triscan 8170 34357 Brake Caliper

Triscan 8170 34357 Brake Caliper

The Triscan 8170 34357 Brake Caliper is a high‑performance component designed for the front axle of certain Mercedes‑Benz models, particularly those equipped with the W123 sedan and its derivatives. This caliper delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features

• Robust Construction: Made from a hardened steel alloy that resists corrosion and wear, ensuring long service life even in harsh environments.
• Optimized Heat Dissipation: The caliper’s design incorporates a large surface area and strategically placed venting to effectively dissipate heat during braking, reducing the risk of fade.
• Precision Fit: Engineered to match the exact dimensions required for the Mercedes‑Benz W123 front axle, including a 57 mm bore diameter that aligns with the vehicle’s brake system architecture.
• Compatibility: Works seamlessly with standard brake pads and rotors used on the same platform, allowing for straightforward installation without the need for additional adapters.
• Lightweight Yet Strong: Despite its high strength, the caliper is relatively lightweight, contributing to overall vehicle weight reduction and improved handling dynamics.

Installation Guide

Installing the Triscan 8170 34357 Brake Caliper involves a series of precise steps that ensure optimal performance and safety. Below is a detailed, step‑by‑step procedure:

1. Preparation: Disconnect the vehicle’s battery to prevent accidental electrical discharge. Remove the wheel and tire from the front axle.
2. Brake System Inspection: Inspect existing brake pads, rotors, and caliper for wear or damage. Replace any components that do not meet manufacturer specifications.
3. Remove Old Caliper: Loosen and remove the mounting bolts securing the old caliper to the steering knuckle. Carefully detach the caliper from the rotor, taking care not to damage the brake lines.
4. Clean Mounting Surface: Use a solvent cleaner to wipe the mounting area on the steering knuckle, ensuring no debris or rust remains that could compromise the seal.
5. Position New Caliper: Place the new caliper onto the mounting surface. Align the bolt holes precisely with the steering knuckle’s pre‑drilled positions.
6. Tighten Mounting Bolts: Secure the bolts in a crisscross pattern, tightening to the manufacturer’s torque specifications (typically around 80 Nm). Use a calibrated torque wrench for accuracy.
7. Reinstall Brake Pads and Rotor: Fit new or refurbished brake pads into the caliper bracket. Reattach the rotor onto the hub, ensuring proper alignment.
8. Brake Line Check: Inspect all brake lines for kinks or damage. Replace any compromised hoses to maintain hydraulic integrity.
9. Bleed the Brake System: Bleed the brakes to remove air bubbles from the hydraulic circuit, following the vehicle’s bleed procedure. This step is critical for maintaining braking performance.
10. Reassemble Wheel and Tire: Mount the wheel back onto the hub, torque the lug nuts in a star pattern to the specified value (usually around 120 Nm).
11. Final Test: Reconnect the battery. Perform a low‑speed test drive, checking for any abnormal noises or vibrations. Verify that the brake pedal feels firm and responsive.

Maintenance Tips

• Regularly inspect brake pads for wear; replace them before they become too thin to avoid damaging the caliper piston.
• Keep the caliper’s contact surfaces clean by applying a high‑temperature brake cleaner during routine maintenance.
• Check for any signs of corrosion on the mounting bolts and replace them if necessary to prevent loosening over time.
• Use only OEM or certified replacement parts when servicing the braking system to maintain compatibility and performance standards.

Performance Benefits

The Triscan 8170 34357 Brake Caliper offers several tangible advantages for drivers:

• Enhanced Stopping Power: The caliper’s design ensures that brake pads apply consistent pressure across the rotor, resulting in reliable deceleration.
• Reduced Fade Risk: Efficient heat dissipation keeps operating temperatures within safe limits, preserving braking effectiveness during prolonged use.
• Improved Longevity: High‑quality materials and precise engineering reduce wear on both the caliper and associated brake components.
• Consistent Handling: The lightweight construction minimizes unsprung mass, contributing to better vehicle dynamics and ride comfort.

Compatibility Summary

This brake caliper is specifically engineered for the front axle of Mercedes‑Benz models that utilize a 57 mm bore diameter. It aligns with the following vehicle series:

• MERCEDES‑BENZ W123 sedan and its derivatives (including the Pagode Cabriolet)
• Related models such as the W124, where the front axle brake system shares similar specifications

When selecting a replacement or upgrade component, ensure that the vehicle’s existing brake hardware matches the caliper’s mounting dimensions and hydraulic requirements.

Conclusion

The Triscan 8170 34357 Brake Caliper stands out as a reliable, high‑performance solution for front‑axle braking systems on select Mercedes‑Benz vehicles. Its robust construction, precise engineering, and compatibility with standard brake components make it an excellent choice for both routine maintenance and performance upgrades.
