1014012492 Left Rear Brake Hose for Geely X7

Product Introduction

1014012492 Left Rear Brake Hose for Geely X7

Our Left Rear Brake Hose is a vital component of vehicle braking systems, designed to safely transmit hydraulic pressure from the brake master cylinder to the left rear brake caliper/drum.

Crafted with an oil-resistant nitrile rubber inner tube, high-tensile steel braid reinforcement, and weatherproof EPDM outer cover, it resists corrosion, abrasion, and extreme temperatures (-40℃~120℃). Compliant with DOT FMVSS 106 standards, it ensures leak-free performance and stable braking. As a direct OE replacement, it fits 90% of mainstream models, restoring reliable braking and enhancing driving safety.

Product Advantage

1.Tri-Layer Durable Structure for Long Service Life

Our high-quality Left Rear Brake Hose features a 3-layer design: oil-resistant nitrile rubber inner tube (compatible with DOT 3/4/5.1 brake fluid), 4-layer high-tensile steel braid (tensile strength ≥2000N/mm²), and weatherproof EPDM outer cover. It passes 1000h salt spray tests with no corrosion, and the service life reaches 100,000 miles—30% longer than ordinary brake hoses, perfectly solving premature wear issues.

2.Ultra-High Pressure Resistance & Leak-Proof Guarantee

Compliant with DOT FMVSS 106 and ECE R116 safety standards, this Left Rear Brake Hose has a working pressure of 3000 psi and burst pressure ≥9000 psi. Every unit undergoes a 4000 psi pressure test for 60 seconds, achieving 100% leak-proof qualification. Even under extreme braking conditions, it maintains stable hydraulic transmission, avoiding brake failure risks caused by hose rupture.

3.Wide Temperature Adaptability for All Climates

The Left Rear Brake Hose maintains stable performance in -40℃~120℃ environments—no hardening in cold winters or softening in hot summers. It passes 500 cycles of -40℃ to 120℃ temperature shock tests without cracking, making it suitable for regions with extreme climates (such as high-altitude cold areas or desert regions) and ensuring reliable braking year-round.

4.OE-Grade Precision for Seamless Replacement

Manufactured in strict accordance with OE dimensions, our Left Rear Brake Hose fits 90% of mainstream models. It uses OE-compatible M10×1.0/M12×1.0 fittings, requiring no drilling or modification during installation. Mechanics and DIY users can complete replacement in 20 minutes—saving 30% of installation time compared to non-OE hoses.

5.Anti-Abrasion & Low-Maintenance Design

The EPDM outer cover of the Left Rear Brake Hose has a wear resistance rating of 4H (per ASTM D3389), effectively resisting scratches from road debris and friction with vehicle components. It also reduces the need for frequent inspections—only requiring routine checks every 20,000 miles. This low-maintenance feature lowers long-term use costs for vehicle owners.

Product Uses

Here are specific application scenarios of Left Rear Brake Hose:

1.Daily Urban Commuting Vehicles

A family sedan suitable for daily urban commuting, frequent starting and stopping can easily lead to brake hose aging. This Left Rear Brake Hose is wear-resistant and oil resistant, capable of stably transmitting brake oil pressure, avoiding brake delay caused by hose failure, and ensuring driving safety during rush hour.

2.SUV & Light Truck Off-Road Use

For off-road scenarios of SUVs or light trucks, the outer layer of the product is made of EPDM rubber that is resistant to gravel scratching, and the steel weaving layer is resistant to bumps and pulls. When driving on unpaved roads, it can resist damage to the hose from mud, branches, and ensure that the braking system works normally in complex road conditions.

3.Extreme Climate Region Vehicles

In the cold northeast region with a temperature of -40 ℃ or the hot southern region with a temperature of 40 ℃, this Left Rear Brake Hose can maintain stable performance without hardening or softening. Solve the problem of traditional hoses cracking and leaking under extreme temperatures, ensuring the reliability of braking throughout the year.

4.Vehicle Brake System Maintenance & Replacement

When the vehicle travels over 100000 kilometers or experiences brake softening or abnormal noise, this product can be used as an OE direct replacement and is compatible with 90% of mainstream car models. No need to modify the installation structure, making it convenient for repair shops or DIY users to quickly replace and restore the performance of the brake system, avoiding safety hazards caused by aging old hoses.

5.Fleet & Commercial Vehicle Daily Operation

Commercial vehicles used for high-frequency use such as taxis and logistics light trucks, with a long lifespan of 100000 kilometers, can reduce replacement frequency and lower fleet operating costs. At the same time, its fatigue resistance and high pressure resistance can cope with frequent braking conditions of commercial vehicles, ensuring daily transportation efficiency and safety.

Product Operate Guide

1. Before installation, ensure that the vehicle is turned off, the handbrake is tightened, and the vehicle is lifted and secured; Remove the left rear tire, find the old brake hose, and disconnect the two end connectors (a wrench is required to avoid damaging the threads).

2. Take out the new hose, align it with the joint and tighten it clockwise (torque 8-10 N · m), do not apply excessive force; After installation, exhaust (requires 2 people to cooperate: one person steps on the brake and the other person loosens the exhaust valve to release air).

3. Reinstall the tires, put down the vehicle, start and lightly apply the brake for testing. After confirming that there are no soft feet or fluid leaks, use it normally; It is recommended to check the condition of the hose every 20000 kilometers to avoid the risk of aging.
