3501200-K00 High-Quality OE-Compatible Corrosion-Resistant Brake Caliper for Great Wall Motor

Product Introduction

3501200-K00 brake caliper for Great Wall Motor

Our car brake calipers are crucial components in the braking system. They house brake pads and use hydraulic pressure to squeeze pads against the brake rotor. This friction restricts rotor movement, slowing down the vehicle.

Available in floating and fixed types, our calipers offer different performance levels. Floating calipers, with a piston on one side and floating on the other, ensure even pressure distribution. Fixed calipers, having pistons on both sides, provide enhanced braking performance.

Made from high - strength materials like aluminum for better heat dissipation and reduced weight, our brake calipers contribute to improved handling and fuel efficiency. They play a vital role in vehicle safety, ensuring quick and reliable braking.

Product Advantage

1. Integrated forging of aviation grade aluminum alloy, combining lightweight and high strength

Using aerospace grade 6061-T6 aluminum alloy, it is formed by 1200 tons of cold forging pressure, which reduces weight by 42% compared to traditional cast iron brake calipers, but can withstand an instantaneous braking pressure of 800 MPa (far exceeding the industry standard of 500 MPa). Lightweight design can reduce suspension load and improve vehicle handling response speed. At the same time, the thermal conductivity of aluminum alloy material reaches 155W/(m · K), effectively suppressing brake heat attenuation and adapting to high-frequency urban commuting scenarios for small cars.

2. Double piston symmetrical layout+ceramic piston ring, improves braking accuracy by 35%

Innovative dual piston symmetrical structure, combined with imported ceramic piston rings, achieves a 92% contact area between brake pads and brake discs during braking (traditional single piston only has 75%), and shortens the braking distance by 1.8 meters compared to the industry average (test data at a speed of 60km/h). The wear resistance of the ceramic ring has been improved by 200%, avoiding direct friction between the metal piston and the cylinder body, extending the service life of the small car brake caliper to over 80000 kilometers, and reducing the frequency of replacement for car owners.

3. IP67 waterproof and rust proof+multi-layer electroplating process, suitable for complex environments

The overall IP67 sealing design can resist the erosion of rainstorm, mud and other bad road conditions, and there is no rust after 500 hours of salt spray test (far more than 240 hours of ISO 9227 standard). The surface is coated with three layers of nickel chromium electroplating process, with a hardness of HV580 and a 150% improvement in scratch resistance, solving the pain point of brake calipers for small cars that are prone to rust and affect braking safety when exposed to the outside for a long time.

4. OE factory compatibility rate of 99.8%, compatible with mainstream small car models

Based on 15 years of experience in automotive parts research and development, the precision of product molds is controlled at ± 0.02mm, which matches the OE numbers of over 200 small car models accurately. Installation does not require additional modifications (with a tested installation compatibility rate of 99.8%). Each brake caliper undergoes 300 simulated brake tests before leaving the factory, with a brake pressure fluctuation value of ≤ 5%, in compliance with the ECE R90 brake system safety certification, ensuring that it meets the original factory performance standards upon installation.

5. Built in heat dissipation channel, reducing thermal attenuation rate by 40%

The side of the cylinder body is designed with 8 spiral heat dissipation guide grooves, which, together with the copper heat dissipation fins built into the piston, can quickly dissipate the heat generated during braking. According to third-party testing, after 10 consecutive emergency brakes (at a speed of 80km-0), the surface temperature of the brake caliper is 65 ℃ lower than that of the regular model, and the thermal attenuation rate is only 12% (industry average of 30%), ensuring the continuous braking stability of the small car on long downhill and congested roads.

Technical Parameters

Product Uses

Here are specific application scenarios of brake caliper:

1. High frequency commuting scenes in cities

Adapting to urban road conditions with an average of 30-50 starts and stops per day, the dual piston symmetrical braking design can quickly respond to traffic lights and congested following needs. At a speed of 60km/h, the braking distance is 1.8 meters shorter than the regular model, reducing the risk of rear end collisions. IP67 waterproof for rainy commuting, 500 hour salt spray test ensures long-term use without rusting, meeting the daily safety travel needs of urban car owners.

2. Long downhill sections in mountainous areas

For mountainous areas with multiple bends and long downhill slopes, there are 8 built-in heat dissipation channels that can quickly dissipate heat. After 10 consecutive braking cycles at 80km/h-0, the temperature drops by 65 ℃, and the thermal attenuation rate is only 12% (industry average of 30%), avoiding a decrease in braking performance. The 800MPa pressure bearing capacity is suitable for frequent braking on steep slopes, ensuring the continuous stability of small cars driving on mountain roads.

3. Long distance high-speed driving

During long-distance high-speed driving, the brake caliper needs to withstand long-term high-speed braking pressure. Its OE original factory 99.8% matching degree ensures stable installation, 300 simulated braking tests (pressure fluctuation ≤ 5%) ensure braking reliability in high-speed emergencies, 155W/(m · K) aluminum alloy thermal conductivity effectively suppresses thermal attenuation, and is suitable for long-distance driving needs across cities and provinces.

4. Winter ice and snow/rainy season muddy road conditions

The IP67 sealing design can resist the erosion of accumulated water and mud after the melting of ice and snow, and prevent internal parts from rusting and sticking. Ceramic piston rings have excellent low-temperature resistance and can still work normally in an environment of -40 ℃. Combined with multi-layer electroplating anti rust technology, they solve the problem of brake system failure in small cars during winter and rainy seasons, and comply with ECE R90 safety certification standards.

5. Modification and upgrade scenarios

To provide solutions for small car modification users who pursue handling performance, the 1.2-1.5kg lightweight design (42% lighter than cast iron models) reduces suspension load and improves vehicle steering response. The HV580 hardness electroplating surface is scratch resistant, suitable for frequent maintenance needs of modified cars, and compatible with mainstream vehicle OE specifications. It can upgrade braking performance without additional modifications.

Product Operate Guide

1. Initialization after installation:

After installation, continuously step on the brake pedal 3-5 times to reset the piston to its working position (ensuring that the brake clearance is ≤ 0.2mm, in compliance with ECE R90 standard), to avoid the failure of the first stage braking.

2. Daily usage precautions:

Avoid frequent sudden braking (which can cause the temperature to rise sharply by over 300 ℃ and accelerate wear and tear). For urban commuting, it is recommended to maintain a following distance of ≥ 5 meters to reduce braking load.

3. Regular inspection:

Check the seals (EPDM rubber must have no cracks) every 20000 kilometers. If brake noise or pedal softness is found, it should be promptly investigated (it is recommended to contact an OE certified repair shop) to avoid safety hazards.

4. Special scenario maintenance:

After driving on rainy/muddy roads, you can lightly step on the brake 1-2 times, use friction to remove impurities from the brake disc, and ensure that the IP67 protection performance does not fail.
