Ergonomics and Structural Design: The Foundation of Control

The structural core of the Pédale de frein avec valve de frein assembly is the robust Support de pédale (Partie 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, le Pédale de frein avec valve de frein 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 Pédale de frein avec valve de frein system are translated linearly into braking force without the “spongieux” feel caused by bracket flex.

Attached to this bracket is the Ensemble de pédale de frein (Partie no. 3504070-50UN), a key element of the Pédale de frein avec valve de frein unité. 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. Surtout, le Pédale de frein avec valve de frein assembly pivots on a precision-ground Arbre de pédale (Partie no. 3504032-50UN), which is supported by multiple Bague – Arbre de pédale de frein unités (Partie no. 3504061-50UN). These bushings are made from self-lubricating composite materials designed to resist seizing even when the grease thickens in extreme Arctic cold.

Le Pédale de frein avec valve de frein system also prioritizes driver feedback. Le Retour printemps – Pédale de frein (Partie no. 3504036-50UN) plays a vital role in the Pédale de frein avec valve de frein fonction. 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 Pédale de frein avec valve de frein effectively disengages the Ensemble de commutateur de feu stop immediately upon release.

Hydraulic and Pneumatic Integration: Dual-System Logic

What distinguishes the Pédale de frein avec valve de frein assembly is its seamless integration of two distinct fluid systems. On the pneumatic side, le Ensemble de valve de frein et de joint de tuyau (Partie no. 3514010-50UN) acts as the command center for the entire Pédale de frein avec valve de frein opération. When the driver depresses the pedal, le Tige de poussée (Partie no. 3504063-50UN) actuates this valve, metering compressed air from the reservoirs to the relay valves. The internal seals of this brake valve are specifically formulated “50UN” compounds, faire le Pédale de frein avec valve de frein resistant to the hardening effects of freezing air and oil contaminants.

Simultanément, the bracket of the Pédale de frein avec valve de frein houses the hydraulic clutch actuation system, centré autour du Ensemble de maître-cylindre d'embrayage (Partie no. 1602110-76W). This cylinder converts mechanical pedal force into hydraulic pressure to disengage the clutch. It is fed by the Ensemble de réservoir d'huile (Partie no. 1602100-50UN), which is mounted high on the Pédale de frein avec valve de frein 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 Pédale de frein avec valve de frein in snowy environments.

The mechanical connection between the pedal and the valve is fine-tuned via the Fourche filetée – Pédale de frein (Partie no. 3504062-50UN), an adjustable component of the Pédale de frein avec valve de frein lien. This adjustable linkage allows mechanics to set the precise pedal free-play. Incorrect free-play in the Pédale de frein avec valve de frein 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 Goupille fendue (Partie no. Q5002016) et Goupille à tête plate (Partie no. Q5100825), simple yet fail-safe fasteners that prevent vibration from altering the critical calibration of the Pédale de frein avec valve de frein.

Electrical Signaling and Safety Interlocks

Beyond mechanical control, le Pédale de frein avec valve de frein assembly serves as a digital signal generator for the truck’s ECU and lighting systems. Le Ensemble de commutateur de feu stop (Partie no. 3720010-A01) is mechanically linked to the brake pedal arm within the Pédale de frein avec valve de frein unité. As soon as the pedal moves, this switch completes the circuit to illuminate the rear brake lights, alerting following traffic. Dans le camion benne CA3250, this signal also disengages the cruise control and exhaust brake, prouvant que le Pédale de frein avec valve de frein is deeply integrated into the vehicle’s logic.

De la même manière, the clutch pedal adjacent to the Pédale de frein avec valve de frein features the Ensemble de commutateur d'embrayage (Partie no. 3754030-76W), monté sur le Ensemble de support de commutateur d'embrayage (Partie 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 Culbuteur – Commutateur d'embrayage (Partie no. 1602027-76W), which must be kept free of ice and mud buildup to function correctly alongside the Pédale de frein avec valve de frein.

The reliability of these electrical components within the Pédale de frein avec valve de frein 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. Inspection régulière du Ensemble de pédale d'embrayage (Partie 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 Pédale de frein avec valve de frein to prevent chafing and short circuits.

Maintenance Protocols and Fastener Security

L'intégrité du Pédale de frein avec valve de frein assembly relies heavily on its mounting hardware. The bracket is secured to the cab firewall using high-strength fasteners like the Boulon à tête hexagonale (Partie no. CQ1500620) et Contre-écrou à bride hexagonale (Partie no. CQ32608). The flange nuts feature serrated faces that bite into the metal surface, resisting the high-frequency vibrations generated by the diesel engine, Assurer le Pédale de frein avec valve de frein reste sécurisé. Utilizing the correct Rondelle à ressort (Partie no. Q40306) prevents these bolts from backing out over thousands of kilometers of rough haul roads, protecting the alignment of the Pédale de frein avec valve de frein.

Au fil du temps, le Bague pédale (Partie no. 1602037-50UN) et le Bloc de limite de pédale (Partie no. 1602092-50UN) act as wear items within the Pédale de frein avec valve de frein 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. Donc, le Pédale de frein avec valve de frein maintenance schedule must include a physical inspection of these rubber isolators and immediate replacement if cracking is observed.

Enfin, le Manche – Coupe d'huile d'embrayage (Partie no. 1602102-76W) and the associated Bloc limite – Pédale d'embrayage (Partie no. 1602038-76W) ensure the hydraulic reservoir on the Pédale de frein avec valve de frein assembly remains stable. A loose reservoir can lead to frothing of the hydraulic fluid due to vibration, introducing air bubbles into the clutch lines.
