ABS 421172 Brake Caliper

ABS 421172 Brake Caliper: Precision in Every Stop

The ABS 421172 Brake Caliper is engineered for drivers who demand uncompromising stopping power and durability. Designed with a focus on high-performance braking, this caliper delivers consistent, reliable performance across a wide range of driving conditions.

Design & Construction

The caliper features a robust aluminum alloy housing that balances strength with lightweight construction. This material choice reduces unsprung mass, enhancing vehicle handling and ride quality. The internal piston is crafted from high-grade steel, ensuring smooth operation and resistance to wear.

Its dual-piston design provides even pressure distribution across the brake pads, resulting in uniform pad wear and extended service life. The caliper’s mounting interface incorporates a precision-machined flange that aligns perfectly with the vehicle’s rear suspension geometry, guaranteeing optimal braking performance.

Performance Characteristics

The ABS 421172 is engineered to deliver:

• Consistent stopping force even under high-temperature conditions.
• Reduced brake fade during prolonged use, thanks to efficient heat dissipation.
• Improved modulation and feel, allowing drivers to maintain better control during emergency stops.

Its design supports both standard and high-performance brake pad compounds, making it suitable for everyday driving as well as spirited performance sessions.

Compatibility & Fitment

The ABS 421172 is specifically tailored for a range of rear-wheel-drive vehicles, including:

• Volkswagen Transporter 5
• VW Multivan 5
• Other VAG platform models with 22mm–44mm brake disc thicknesses

Its standardized mounting dimensions and bolt patterns ensure a straightforward installation process, compatible with OEM specifications.

Installation Guide

1. Remove the existing caliper by disconnecting brake lines, unscrewing mounting bolts, and carefully lifting the wheel assembly.
2. Inspect the brake pads and rotors for wear; replace if necessary to maintain optimal performance.
3. Position the new ABS 421172 caliper onto the mounting flange, aligning all bolt holes precisely.
4. Screw in the mounting bolts using a torque wrench set to the manufacturer’s specifications.
5. Reconnect brake lines, ensuring no leaks and proper hydraulic pressure.
6. Reinstall the wheel and perform a brake fluid bleed to eliminate air from the system.
7. Test drive at low speeds to confirm correct operation before resuming normal driving conditions.

Maintenance & Care

To preserve peak performance, follow these maintenance steps:

• Regularly inspect brake fluid levels and replace the fluid according to the vehicle’s service schedule.
• Check for pad wear indicators; replace pads when they reach the minimum thickness threshold.
• Ensure that the caliper pistons remain clean by removing any debris or brake dust buildup.
• Periodically verify that all mounting bolts are torqued to spec, preventing loosening over time.
