ABS 420432 Brake Caliper

ABS 420432 Brake Caliper

The ABS 420432 Brake Caliper is a high‑performance braking component engineered for optimal stopping power and durability. Designed with precision machining and advanced materials, this caliper delivers consistent performance across a wide range of driving conditions.

Key Features & Design Highlights

• Material Composition: Constructed from high‑strength cast iron reinforced with thermal‑resistant alloy inserts, the caliper resists wear and maintains structural integrity under high temperatures.
• Dual‑Piston Configuration: The dual‑piston design ensures even pressure distribution across brake pads, enhancing braking efficiency and reducing pad wear.
• Integrated ABS Sensor Mounting: Features a dedicated mounting point for Anti‑Lock Braking System (ABS) sensors, allowing seamless integration into modern vehicle electronic control units.
• Optimized Heat Dissipation: The caliper’s internal geometry incorporates ventilated chambers that facilitate rapid heat transfer, preventing brake fade during prolonged use.
• Lightweight Construction: Despite its robust build, the component is engineered to be lightweight, contributing to overall vehicle weight reduction and improved fuel efficiency.

Compatibility & Vehicle Integration

The ABS 420432 is specifically tailored for a range of Peugeot models, ensuring perfect fitment and performance. Commonly paired with the following vehicle series:

• Peugeot 605 (6B)
• Peugeot 607 (9D, 9U)
• Peugeot 4400.G6, 4400.L2, and 4400.A4 variants
• Other models featuring a 16‑valve HDi Turbo engine configuration

Each installation requires the caliper to be mounted on the rear right side of the vehicle’s braking system, aligning with the standard rear brake assembly layout. The design accommodates a bremsscheibendicke (rotor thickness) range of 10 mm to 33 mm, ensuring versatility across different rotor specifications.

Installation Guidelines

1. Preparation: Secure the vehicle on a stable lift and remove the wheel. Drain brake fluid if necessary before proceeding.
2. Removal of Existing Caliper: Detach the caliper from the mounting bracket using appropriate socket sizes, carefully noting the position of ABS sensor connections.
3. Mounting the New Caliper: Align the ABS 420432 with the mounting bracket and secure it using torque specifications provided in the manufacturer’s service manual. Ensure that the dual pistons are correctly seated against the brake pads.
4. Sensor Integration: Connect the ABS sensor to the dedicated mounting point, verifying proper alignment to avoid signal interference.
5. Reassembly: Reinstall brake pads and rotor, then reattach wheel. Refill brake fluid to the recommended level and bleed the braking system to eliminate air pockets.

Maintenance & Longevity

Regular inspection of the caliper is essential for maintaining peak performance:

• Brake Pad Wear: Replace pads when thickness falls below 2 mm. The dual‑piston design ensures even pad wear, extending service life.
• Caliper Seal Check: Inspect the piston seals for leaks or deformation. A compromised seal can lead to reduced braking force.
• Fluid Quality: Use high‑quality brake fluid as specified by the vehicle manufacturer. Contaminated fluid can corrode internal components.
• Heat Management: In high‑performance driving scenarios, consider installing brake cooling ducts to enhance heat dissipation and prevent fade.
