ABS 423111 Brake Caliper

ABS 423111 Brake Caliper

The ABS 423111 Brake Caliper is a high‑performance braking component engineered for optimal stopping power and durability in modern automotive applications. Designed with precision machining and advanced material science, this caliper delivers consistent performance across a wide range of driving conditions.

Key Features

• High‑Strength Construction: Made from gray cast iron, the caliper offers excellent heat dissipation and resistance to wear, ensuring reliable operation even under heavy braking loads.
• Optimized Geometry: The internal piston chamber is engineered for efficient fluid flow, reducing pressure drop and improving brake response.
• Compact Design: Its streamlined shape allows easy integration into tight engine bay spaces without compromising airflow or cooling.
• Robust Mounting System: Equipped with standardized mounting flanges that align with OEM specifications, facilitating straightforward installation on compatible vehicles.

Compatibility and Applications

The ABS 423111 Brake Caliper is specifically tailored for use in the rear axle of certain Mercedes‑Benz models. It matches the original equipment specifications for:

• Mercedes‑Benz ML series (rear axle)
• Mercedes‑Benz R series (rear axle)
• Various other vehicles that employ a 14 mm to 40 mm brake disc thickness range

Its design accommodates the standard hydraulic system used in these models, ensuring seamless integration with existing brake lines and master cylinders.

Material Composition

The caliper’s core is fabricated from gray cast iron (GCI), a material chosen for its:

• High thermal conductivity, which helps dissipate heat generated during braking.
• Excellent wear resistance, extending the lifespan of the brake pads and rotors it supports.
• Structural rigidity, maintaining consistent piston alignment under load.

Performance Characteristics

When paired with compatible brake pads and rotors, the ABS 423111 Brake Caliper delivers:

• Consistent stopping distances across a range of speeds.
• Reduced fade during prolonged braking sessions due to efficient heat management.
• Improved pedal feel and reduced effort required from the driver, thanks to optimized hydraulic pressure distribution.

Installation Guidelines

1. Preparation: Ensure the vehicle’s brake system is depressurized. Remove any existing caliper components carefully.
2. Mounting: Align the caliper’s mounting flanges with the corresponding holes on the rear axle housing. Secure with the supplied bolts, tightening to the manufacturer’s torque specifications.
3. Piston Alignment: Verify that the piston is centered within the chamber and free of debris or damage.
4. Brake Fluid Check: Refill the brake system with fresh fluid, ensuring no air bubbles remain in the lines.
5. Testing: After installation, perform a low‑speed test drive to confirm proper operation and absence of leaks or unusual noises.

Maintenance Recommendations

Regular inspection is essential for maintaining optimal braking performance. Follow these steps during routine maintenance:

• Inspect the caliper pistons for signs of wear or corrosion.
• Check the mounting bolts for tightness and replace if necessary.
• Verify that brake fluid levels remain within recommended ranges.
• Replace brake pads when pad thickness falls below manufacturer guidelines.
