Unlike standard control units, this ruggedized Brake Pedal With Brake Valve module integrates pneumatic braking precision with hydraulic clutch actuation into a single, frost-resistant architecture. Mastering the intricacies of the Brake Pedal With Brake Valve is essential for fleet operators who demand instant deceleration and seamless gear shifts in temperatures plummeting to -50°C.

Brake Pedal With Brake Valve

Ergonomics and Structural Design: The Foundation of Control

The structural core of the Brake Pedal With Brake Valve assembly is the robust Pedal Bracket (Part No. 3504031-76W). This component is engineered to withstand the repetitive high-force inputs typical of dump truck operations in mining and construction. In the FAW J6P Russian spec, the Brake Pedal With Brake Valve bracket is manufactured from high-tensile steel, providing a rigid mounting point for both the brake and clutch mechanisms. This rigidity ensures that pedal inputs into the Brake Pedal With Brake Valve system are translated linearly into braking force without the “spongy” feel caused by bracket flex.

Attached to this bracket is the Brake Pedal Assembly (Part No. 3504070-50A), a key element of the Brake Pedal With Brake Valve unit. The pedal arm geometry is optimized for the specific seating position of the J6P cabin, offering a mechanical advantage that allows the driver to modulate massive braking power with manageable foot pressure. Crucially, the Brake Pedal With Brake Valve assembly pivots on a precision-ground Pedal Shaft (Part No. 3504032-50A), which is supported by multiple Bushing – Brake Pedal Shaft units (Part No. 3504061-50A). These bushings are made from self-lubricating composite materials designed to resist seizing even when the grease thickens in extreme Arctic cold.

The Brake Pedal With Brake Valve system also prioritizes driver feedback. The Return Spring – Brake Pedal (Part No. 3504036-50A) plays a vital role in the Brake Pedal With Brake Valve function. Unlike standard springs that may become brittle and snap at -40°C, these springs undergo a specialized heat treatment and shot-peening process to enhance their fatigue life and low-temperature ductility. This ensures the pedal returns crisply to its neutral position every time, preventing brake drag and ensuring the Brake Pedal With Brake Valve effectively disengages the Stop Lamp Switch Assembly immediately upon release.

Hydraulic and Pneumatic Integration: Dual-System Logic

What distinguishes the Brake Pedal With Brake Valve assembly is its seamless integration of two distinct fluid systems. On the pneumatic side, the Brake Valve and Pipe Joint Assembly (Part No. 3514010-50A) acts as the command center for the entire Brake Pedal With Brake Valve operation. When the driver depresses the pedal, the Push Rod (Part No. 3504063-50A) actuates this valve, metering compressed air from the reservoirs to the relay valves. The internal seals of this brake valve are specifically formulated “50A” compounds, making the Brake Pedal With Brake Valve resistant to the hardening effects of freezing air and oil contaminants.

Simultaneously, the bracket of the Brake Pedal With Brake Valve houses the hydraulic clutch actuation system, centered around the Clutch Master Cylinder Assembly (Part No. 1602110-76W). This cylinder converts mechanical pedal force into hydraulic pressure to disengage the clutch. It is fed by the Oil Reservoir Assembly (Part No. 1602100-50A), which is mounted high on the Brake Pedal With Brake Valve bracket to ensure gravity feeding. The reservoir is made from a translucent, impact-resistant polymer that allows for quick visual fluid level checks without opening the cap, reducing the risk of introducing moisture into the hygroscopic brake fluid—a critical maintenance advantage for the Brake Pedal With Brake Valve in snowy environments.

The mechanical connection between the pedal and the valve is fine-tuned via the Threaded Fork – Brake Pedal (Part No. 3504062-50A), an adjustable component of the Brake Pedal With Brake Valve linkage. This adjustable linkage allows mechanics to set the precise pedal free-play. Incorrect free-play in the Brake Pedal With Brake Valve system can lead to two dangerous scenarios: excessive travel causing delayed braking, or zero play causing the brakes to bind. The threaded fork is secured with a Cotter Pin (Part No. Q5002016) and Flat Head Pin (Part No. Q5100825), simple yet fail-safe fasteners that prevent vibration from altering the critical calibration of the Brake Pedal With Brake Valve.

Electrical Signaling and Safety Interlocks

Beyond mechanical control, the Brake Pedal With Brake Valve assembly serves as a digital signal generator for the truck’s ECU and lighting systems. The Stop Lamp Switch Assembly (Part No. 3720010-A01) is mechanically linked to the brake pedal arm within the Brake Pedal With Brake Valve unit. As soon as the pedal moves, this switch completes the circuit to illuminate the rear brake lights, alerting following traffic. In the CA3250 dump truck, this signal also disengages the cruise control and exhaust brake, proving that the Brake Pedal With Brake Valve is deeply integrated into the vehicle’s logic.

Similarly, the clutch pedal adjacent to the Brake Pedal With Brake Valve features the Clutch Switch Assembly (Part No. 3754030-76W), mounted on the Clutch Switch Bracket Assembly (Part No. 1602250-76W). This switch prevents the engine from starting unless the clutch is fully depressed, a safety interlock that prevents the truck from lurching forward if started in gear. The actuation of these switches relies on the precise movement of the Rocker Arm – Clutch Switch (Part No. 1602027-76W), which must be kept free of ice and mud buildup to function correctly alongside the Brake Pedal With Brake Valve.

The reliability of these electrical components within the Brake Pedal With Brake Valve assembly is ensured by their IP67-rated enclosures, protecting internal contacts from the condensation that forms in the cab when the heater battles the Siberian cold. Regular inspection of the Clutch Pedal Assembly (Part No. 1602020-76W) involves checking these switches for continuity and ensuring the wiring harnesses are securely routed away from the moving pedal arms of the Brake Pedal With Brake Valve to prevent chafing and short circuits.

Maintenance Protocols and Fastener Security

The integrity of the Brake Pedal With Brake Valve assembly relies heavily on its mounting hardware. The bracket is secured to the cab firewall using high-strength fasteners like the Hexagon Head Bolt (Part No. CQ1500620) and Hexagon Flange Lock Nut (Part No. CQ32608). The flange nuts feature serrated faces that bite into the metal surface, resisting the high-frequency vibrations generated by the diesel engine, ensuring the Brake Pedal With Brake Valve remains secure. Utilizing the correct Spring Washer (Part No. Q40306) prevents these bolts from backing out over thousands of kilometers of rough haul roads, protecting the alignment of the Brake Pedal With Brake Valve.

Over time, the Pedal Bushing (Part No. 1602037-50A) and the Pedal Limit Block (Part No. 1602092-50A) act as wear items within the Brake Pedal With Brake Valve structure. The limit block cushions the pedal’s return stroke, preventing metal-on-metal impact noise. If this rubber block degrades, the pedal travel may exceed specifications, potentially damaging the internal piston of the master cylinder. Therefore, the Brake Pedal With Brake Valve maintenance schedule must include a physical inspection of these rubber isolators and immediate replacement if cracking is observed.

Finally, the Sleeve – Clutch Oil Cup (Part No. 1602102-76W) and the associated Limit Block – Clutch Pedal (Part No. 1602038-76W) ensure the hydraulic reservoir on the Brake Pedal With Brake Valve assembly remains stable. A loose reservoir can lead to frothing of the hydraulic fluid due to vibration, introducing air bubbles into the clutch lines. By maintaining the tight tolerances of the Brake Pedal With Brake Valve assembly using only genuine FAW parts, operators guarantee that their fleet remains operational and safe, regardless of the harsh environmental conditions encountered in the Russian North.
