As a core offering within our premium SITRAK SPARE PARTS catalog, the 810W48235-5077 Brake Pedal Assembly replaces worn or inferior pedals that cause spongy response, premature switch failure, or bracket fatigue. Fleet data from over 2,300 SITRAK C7H and T7H tractors demonstrates a 67% reduction in brake-related driver complaints and a 44% improvement in stopping distance consistency when using this OE-spec assembly.
The 810W48235-5077 Brake Pedal Assembly is an OEM-grade solution meticulously designed for SITRAK medium and heavy trucks requiring fail-safe brake actuation. Unlike generic aftermarket pedals that use thin-gauge steel or low-grade bushings, this assembly features a forged alloy steel arm with a 5.2:1 mechanical leverage ratio, reducing driver fatigue while maximizing master cylinder input force. The pedal incorporates a precision-ground pivot shaft and self-lubricating bronze bearings, ensuring smooth articulation for over 2 million cycles without galling or play.
Every 810W48235-5077 Brake Pedal Assembly undergoes 100% dimensional verification using laser scanning to confirm bracket angles, pedal pad contour, and switch mounting tolerances within ±0.2mm. The pedal pad is overmolded with UV-stable, oil-resistant rubber featuring an anti-slip tread pattern that maintains grip even when contaminated with diesel or hydraulic fluid. This design choice directly contributes to reduced foot slippage during emergency braking, a critical factor in collision avoidance scenarios for fully loaded SITRAK C9H 6×6 vehicles operating in mining and logging environments.
The 810W48235-5077 Brake Pedal Assembly utilizes a hot-forged chromium-molybdenum steel arm rated for 3,500 N applied force. The dual-row needle bearing pivot reduces friction by 38% compared to plastic bushings, delivering consistent pedal effort over temperature extremes.
Unlike mechanical contact switches that wear out, the assembly includes a non-contact Hall-effect sensor (IP67 sealed) providing 5 million+ actuations. The sensor outputs both normally open and closed signals for redundant brake light and ECU logic.
The 810W48235-5077 Brake Pedal Assembly features a dual-rate return spring (initial 15N/mm, secondary 32N/mm) that eliminates dead-band feel. An integrated rubber over-travel stop absorbs pedal stomp energy, preventing linkage damage during panic braking.
All steel components receive a 12-micron zinc-nickel plating followed by cathodic e-coat (500h salt spray resistance). This surpasses OE requirements, ensuring no rust-induced stiffness even in coastal or winter road-salt conditions.
The genuine 810W48235-5077 Brake Pedal Assembly is manufactured from 42CrMo4 chromoly steel, heat-treated to 38-42 HRC, delivering an ultimate tensile strength of 1,200 MPa. This metallurgical selection prevents arm bending or fracture even after 2 million braking events with a 60-ton gross vehicle weight. In contrast, counterfeit pedals often use low-carbon steel (A36) with no heat treatment, which exhibits plastic deformation after 200,000 cycles, resulting in a sinking pedal feel and reduced brake stroke. Third-party fatigue testing (SAE J1441) confirms that the genuine assembly withstands 2.5 million alternating load cycles (0-3,000 N) without crack initiation, while generic parts fail at an average of 310,000 cycles.
A 48-month field study involving 1,100 SITRAK T7H 8×4 logging trucks operating in British Columbia’s mountainous terrain compared genuine 810W48235-5077 Brake Pedal Assembly units against low-cost replacements. The genuine parts exhibited zero pedal-side play, no switch failures, and maintained original pedal force linearity after 680,000 km. Aftermarket pedals showed bushing wear by 150,000 km, causing lateral pedal wobble and inconsistent brake application. The proprietary dual-lip dust seal integrated into the pivot area also prevented grit intrusion, extending bearing life by a factor of four compared to open-bushing designs.
Before installation, disconnect the battery and remove the driver-side kick panel. Using an 18mm socket, unbolt the original pedal’s four mounting nuts (torqued to 45 Nm from factory). Disconnect the brake switch harness by depressing the locking tab. Compare the new 810W48235-5077 Brake Pedal Assembly with the removed part to verify identical bracket geometry. Apply a thin layer of anti-seize compound to the pivot bolt threads, then position the assembly onto the firewall studs. Hand-tighten nuts in a cross pattern, then torque to 45 Nm ±5 Nm using a calibrated wrench.
Reconnect the Hall-effect brake switch, ensuring the plunger contacts the pedal arm’s actuation ramp with 1-2mm preload. Perform a functional test: with ignition on, depress the pedal – brake lights must illuminate after 6-8mm of travel. Verify no lateral wobble by applying a 150N side force; maximum allowable deflection is 0.5mm. Finally, bleed the brake system only if the master cylinder pushrod length was adjusted. Do not modify the pedal’s integral over-travel stop; doing so will void the 2-year/400,000 km warranty. Always replace the self-locking nuts with new ones (included in genuine kit) to maintain clamping force.
Each genuine 810W48235-5077 Brake Pedal Assembly is produced in an IATF 16949 certified facility dedicated to SITRAK safety-critical components. The forging process uses 2,500-ton mechanical presses with real-time temperature monitoring to ensure consistent grain flow. After shot blasting, every pedal arm undergoes magnetic particle inspection (MPI) to detect any subsurface flaws. The pivot bore is diamond-honed to Ra 0.4µm surface finish, then assembled with precision-grade needle bearings (ISO P5 tolerance).
Final assembly includes a 100% force-displacement test: a robotic arm applies 0-3,000 N force while recording pedal angle versus output travel. Units that deviate more than 2% from the master curve are rejected. Additionally, a random sample from each batch (5%) is subjected to 1.5 million cycle endurance testing in a thermal chamber cycling from -40°C to +80°C. Only batches achieving zero cracks or force decay beyond 5% receive the 810W48235-5077 certification mark.

A 30-month fleet evaluation involving 1,950 SITRAK C7H and C9H trucks operating in Australian iron ore mines (ambient temperatures reaching 52°C, high airborne dust, severe vibration) compared genuine 810W48235-5077 Brake Pedal Assembly against low-cost imported pedals. The genuine units showed zero pivot wear, no switch electrical faults, and maintained original pedal force linearity after 520,000 km. Aftermarket pedals suffered from bushing extrusion and switch contact welding by 90,000 km, causing unintended brake light activation or complete signal loss. Fleet maintenance logs recorded a 71% reduction in brake-related roadside inspections and a 63% decrease in driver complaints regarding pedal “mushiness”.
In SITRAK lab simulation, the 810W48235-5077 Brake Pedal Assembly survived 3 million mechanical cycles under simultaneous 1,500 N vertical load and ±25 N side load (simulating driver foot movement). Post-test disassembly revealed less than 0.05mm of pivot bore growth. The assembly also passed a 96-hour mixed salt spray / condensation test (according to ISO 11997-1) with no red rust or loss of e-coat adhesion. For fleet operators seeking maximum uptime and lowest total cost of ownership, this genuine pedal assembly delivers the definitive balance of robust design, corrosion resistance, and fail-safe braking performance.
Always verify the laser-etched QR code on the product packaging and the “SITRAK GENUINE” hologram affixed to the pedal arm. Genuine 810W48235-5077 Brake Pedal Assembly units have a smooth, uniform e-coat finish with no bare metal edges; counterfeit parts often use spray paint that chips easily and low-grade bushings that deform at 70°C. Authentic assemblies include a factory test certificate (force-travel curve, MPI report) and a 2-year / 400,000 km warranty against material or workmanship defects. Store the assembly in its original sealed bag until installation to prevent dust contamination of the pivot bearings. Use within 36 months of the production date stamped on the arm.
For optimal service life, do not apply grease or oil to the pedal pad or switch actuation ramp. Inspect the assembly annually for any abnormal lateral play; if side-to-side movement exceeds 1.5 mm at the pad center, replace the pivot bearings using the official service kit.
