Liugong 15K2004 Brake Caliper: Precise braking control for stable heavy-load operation, ensuring equipment braking safety.

Safety
In the braking system of construction machinery, the brake caliper converts hydraulic energy into braking force. “ Core actuator — — Whether it’s maintaining precise speed control when descending a slope under full load or performing emergency stops in the narrow spaces on a construction site, both rely on the brake master cylinder’s accurate actuation. If the master cylinder exhibits slow braking response, seal failure, or insufficient load-bearing capacity, it can easily lead to delayed braking, brake pull, and even cause equipment to slide down slopes or result in collisions—serious safety hazards that directly threaten the safety of personnel and equipment. LiuGong. 15K2004 Brake caliper, custom-made by the manufacturer. “ Precision braking tool ” With its advantages of efficient braking and heavy-load-resistant sealing, it provides stable and reliable braking performance for various heavy-duty operation scenarios, making it the go-to braking system for equipment. “ Security Core ”。

Factory-level deep integration: Perfectly fitted, ready to use right out of the box.

Liugong 15K2004 The development of the brake caliper is fully aligned with the braking system structure and hydraulic parameters of specific model equipment, achieving— “ Perfect match of size and performance ” The mounting boss and bolt hole positions of the wheel cylinder precisely match those of the brake backing plate, with the tolerance controlled within... 0.05 mm Inside, it can be directly assembled without the need for additional grinding or adjustments—professional repair personnel. 30  The replacement can be completed within minutes, significantly reducing equipment downtime. The hydraulic chamber volume and piston stroke of the slave cylinder are fully compatible with the output parameters of the vehicle’s master brake cylinder, thereby avoiding issues caused by mismatched parameters in non-original slave cylinders. “ Brake soft pedal “” The itinerary is too long. ”  Problem: After assembly, the hydraulic system can achieve precise synchronization between the brake pedal and the master cylinder action without any need for adjustment, thereby eliminating... “ The rear brake has failed after installation. “” Insufficient braking force ”  Addressing potential hazards. This factory-level compatibility allows the brake booster to integrate swiftly into the braking system, immediately delivering stable braking performance.

High-efficiency braking performance: Instant response, stable control of heavy loads.

For construction machinery “ Heavy-duty, high-frequency braking ”  The demand, LiuGong 15K2004 The brake caliper adopts an optimized hydraulic transmission structure to achieve... “ Precise braking and instant response ” The master pump piston is made of a high-strength alloy material and undergoes precision honing, with the clearance fit between the piston and cylinder barrel controlled within... 0.01–0.03 mm Meanwhile, the hydraulic oil provides smooth operation without any jerks, and the brake response time is shortened to... 0.2  Within seconds, it can rapidly transmit braking force in response to sudden situations. The piston area and hydraulic chamber design have been mechanically calculated, ensuring that, under the rated hydraulic pressure, the braking force output is significantly higher than that of conventional master cylinders. 15% Above, even when the equipment is fully loaded (such as a loader bucket filled to capacity with ore), it can still achieve... “ Simply lightly pressing the pedal activates the brake. ” This prevents excessively long braking distances caused by insufficient braking force. Meanwhile, the return spring built into the wheel cylinder is made of high-elasticity alloy steel wire that has been strengthened through heat treatment, ensuring a uniform and stable return force. After braking, the piston can quickly return to its original position without any lag, reducing brake pad wear and extending the service life of braking components.

Heavy-duty structural design: strong load-bearing capacity, impact resistance

Considering that construction machinery frequently operates under heavy-load braking conditions (such as transportation on mine slopes and frequent starts and stops at infrastructure sites), LiuGong... 15K2004 The brake caliper has been specifically reinforced for structural strength: the caliper cylinder body adopts... 20# High-quality seamless steel pipe, forged as a whole and subjected to aging treatment, with tensile strength reaching... 520 MPa The above-mentioned components can withstand cylinder body deformation and hydraulic shocks caused by prolonged heavy-duty braking, thereby preventing cylinder body cracking and bulging. The piston guide bushings are made of wear-resistant cast iron and have a phosphatized surface with a hardness reaching... HB180-220 It can reduce frictional losses during the reciprocating motion of the piston and prevent piston misalignment caused by excessive wear of the guide sleeve. The connection bracket for the sub-pump is fabricated by welding thickened steel plates, and the weld joints have undergone non-destructive testing ( UT ), ensuring there are no welding defects, enabling stable support of lateral forces during braking, and preventing uneven stress distribution that could lead to loose installation or brake pull.

Long-lasting sealing protection: Leak-proof and durable, suitable for complex environments.

The sealing performance of the brake caliper directly determines braking reliability, LiuGong. 15K2004 Layering up on sealing design: Adopting... “ Main seal +  Dustproof seal ”  Double-layer structure: The primary seal is made of polyurethane, a material that is both high-pressure and oil-resistant. After being molded under pressure, the seal lip features a precisely controlled interference fit. 30 MPa Under rated hydraulic pressure, there is no leakage, while simultaneously reducing the resistance to piston movement. The dust-sealing ring is made of nitrile rubber and features an integrated metal skeleton, which effectively prevents dust and mud/water from the working environment from entering the cylinder bore, thus avoiding damage to the seals, contamination of hydraulic oil, and brake failure caused by seal failure. The surface roughness of the sealing groove is controlled within... Ra 0.8 μm Next, ensure that the seal fits tightly against the groove to further enhance sealing reliability. In addition, the hydraulic oil passages inside the master pump have been meticulously cleaned to remove any iron filings or impurities, thereby preventing blockages that could cause brake sticking and ensuring stable sealing performance over the long term.

End-to-end quality control system: Original manufacturer standards, guaranteed quality.

From raw material entry to finished product shipment, LiuGong. 15K2004 The brake caliper must undergo multiple rounds of rigorous quality inspections: core components such as the cylinder body and pistons must pass material composition analysis and mechanical performance testing to ensure that the materials meet the required standards. During the production process, each caliper must undergo hydraulic sealing tests (at... 35 MPa Maintain pressure under stress. 5  No leakage within minutes; piston movement flexibility test (ensuring smooth reciprocating motion without jamming); braking force output test (verifying that the braking force meets the standard); during the finished-product stage, a high- and low-temperature cycling test must also be conducted (at...). - 40℃ To 120℃ Cyclic operation within the temperature range 50  Next, perform stability testing of sealing performance and durability testing (simulating heavy-load braking cycles). 10000  Next, we verify the structural integrity and sealing reliability. Each test strictly adheres to LiuGong’s original factory standards for brake components; any nonconforming products are immediately rejected, ensuring that every master cylinder entering the market can reliably guarantee braking safety.
