4110142 Brake Hose

Product Overview

The 4110142 Brake Hose is a high‑performance hydraulic connector designed for automotive braking systems. It serves as the critical link between the brake master cylinder and the wheel calipers or drum brakes, transmitting pressurized fluid that activates the vehicle’s stopping mechanism.

Key Features

• Durable Construction: Made from reinforced rubber with a steel braided sleeve to resist abrasion, heat, and chemical exposure.
• High Pressure Capacity: Rated for up to 250 bar (3600 psi), ensuring reliable operation under extreme braking loads.
• Temperature Range: Operates effectively from –40 °C to +120 °C, accommodating both cold climates and high‑performance driving conditions.
• Leak‑Proof Design: Features a double O‑ring seal system that prevents fluid loss even under vibration or shock.
• Compatibility: Specifically engineered for BMW models such as the E81, E90, and related variants, but also suitable for other vehicles with matching fittings.

Technical Specifications

Application Guide

The 4110142 Brake Hose is primarily used in the rear brake circuit of BMW vehicles, particularly models such as the E81 (1‑series) and E90 (3‑series). Its design accommodates the specific geometry and pressure requirements of these cars.

Installation Steps

1. Preparation: Drain the brake fluid system to avoid contamination. Clean all mating surfaces with isopropyl alcohol.
2. Threading: Apply anti‑seize lubricant to the M10 threads of both the hose and the caliper or master cylinder fittings.
3. Connection: Screw the hose onto the fitting, ensuring a snug fit without cross‑threading. Tighten to the specified torque using a calibrated wrench.
4. Sealing: Verify that the double O‑ring seals are seated correctly and free of debris.
5. Bleeding: Refill the brake system with fresh fluid and bleed all brakes to remove air pockets, following manufacturer guidelines.

Maintenance Tips

• Inspect hoses annually for signs of wear such as cracking, bulging, or discoloration.
• Replace any hose that shows evidence of damage immediately to prevent brake failure.
• Store spare hoses in a cool, dry place away from direct sunlight and chemicals.

Performance Benefits

By incorporating the 4110142 Brake Hose, vehicle owners can expect:

• Consistent Braking Response: The high‑pressure rating ensures that brake fluid reaches the calipers without loss, maintaining optimal stopping power.
• Extended Service Life: The reinforced construction resists common failure modes such as abrasion and heat degradation.
• Reliability Under Stress: Whether in everyday driving or spirited performance sessions, the hose maintains integrity under vibration and rapid pressure changes.

Compatibility Summary

The product is tailored for BMW models that use a 12 mm inner diameter brake line with M10 threaded fittings. Commonly matched vehicles include:

• BWM 1‑Series (E81, E82)
• BWM 3‑Series (E90, E91, E92, E93)
• Other European cars with similar hydraulic specifications

Conclusion

The 4110142 Brake Hose delivers reliable, high‑pressure fluid transfer essential for safe braking performance. Its robust construction, precise engineering, and compatibility with a range of BMW models make it an indispensable component for maintaining vehicle safety and handling integrity.
