A dual‑pin mounting system allows for secure attachment to the brake rotor, providing stability during high‑speed braking.

Material Composition

• Housing: Stainless steel alloy (AISI 304)
• Piston: High‑strength alloy steel (ASTM A516 Grade 70)
• Seals: EPDM rubber with reinforced silicone for temperature resilience

Compatibility & Vehicle Integration

The ABS 421351 is engineered to fit a wide array of vehicles, including but not limited to:

• Ford – models equipped with the 6G912B302 series and RM6G9J2B302 variants.
• Volvo – compatible with V60 I, V70 3, V70 2, and other models featuring the 1432362 part number.
• Land Rover – suitable for Range Rover Evoque, Discovery Sport, Freelander 2 SUV, and related platforms using LR007201 or LR015387 rotors.
• Other European brands that utilize the 421351 designation across various brake systems.

Its universal mounting design ensures seamless integration with existing brake assemblies, reducing installation time and complexity.

Performance Characteristics

• High Heat Dissipation: The stainless steel construction allows for efficient heat transfer, minimizing fade during prolonged braking sessions.
• Consistent Piston Travel: Precision machining guarantees uniform piston movement, resulting in predictable brake feel and reduced pedal effort.
• Low Maintenance: Durable seals and corrosion‑resistant materials reduce the frequency of replacement, extending service intervals.

Installation Guidelines

1. Preparation: Clean all mounting surfaces to remove debris and ensure proper contact.
2. Alignment: Position the caliper over the rotor, aligning the mounting pins with the corresponding holes.
3. Tightening Sequence: Use a torque wrench to tighten bolts in a cross‑pattern sequence, following manufacturer specifications for each vehicle model.
4. Brake Fluid Check: After installation, bleed the brake system to eliminate air pockets and verify fluid integrity.

Maintenance & Longevity

Routine inspections should focus on:

• Checking for piston wear or leakage.
• Inspecting seals for cracking or deformation.
• Ensuring mounting bolts remain torqued to specification.

When signs of wear appear, replace the caliper promptly to maintain braking safety and performance.
