Combination pedal assembly – genuine HOWO complete brake and clutch pedal unit for MAX 4X2
This Combination pedal assembly includes every component from the pedal cover to the mounting brackets, return spring, bushings, and all fasteners. No extra parts are needed for a full replacement of the pedal system.
The part uses forged steel for the pedal arm, cast aluminum for the base, and hardened steel for shafts and pins. All components are corrosion-resistant and designed for heavy-duty use.
Every bracket, bushing, and seal in this Combination pedal assembly is machined to SINOTRUK’s OE specifications, guaranteeing that the pedal height, travel, and feel match the original factory calibration.
With spring washers, cotter pins, split pins, and locking nuts, this Combination pedal assembly ensures that all fasteners stay secure even under the severe vibration of a heavy truck, reducing maintenance frequency.
The part is mounted to the firewall and connects the driver’s foot input to the brake master cylinder and clutch master cylinder (or air valve). When the driver presses the pedal, the pedal arm rotates on the shaft, transmitting force through the connecting fork and pushrod. The return spring ensures the pedal returns to its rest position when released.
The wear sleeve and bushings reduce friction and allow smooth articulation. The limit bolt prevents over-travel, and the brake light switch bracket ensures the brake lights illuminate correctly. The pedal base provides a rigid mounting point. All fasteners and seals keep the assembly secure and protected from contaminants. A properly functioning Combination pedal assembly gives the driver confident, responsive control over the vehicle’s braking and clutch systems, enhancing safety and driving comfort.
Before installation, disconnect the battery and remove the old pedal assembly. Mount the pedal base to the firewall using the provided hexagon bolts and flange nuts, ensuring the sealing gasket is correctly positioned. Install the pedal shaft, wear sleeve, and bushings. Attach the brake pedal arm assembly onto the shaft, securing with the cotter pin and split pin.
Install the return spring between the pedal and the bracket. Connect the master cylinder pushrod using the connecting fork and lock with the hexagon nut. Mount the brake light switch bracket and adjust the limit bolt to set the correct pedal travel. Install the cover plate and the clutch harness bracket. Finally, check all fasteners for torque and test the pedal operation. The part is now ready for use.
If the pedal feels spongy or has excessive free play, check the master cylinder pushrod adjustment and the return spring tension. A squeaking noise indicates lack of lubrication on the shaft or bushings; apply lithium grease to the pivot points. If the pedal does not return fully, the return spring may be broken or the shaft may be binding – inspect and replace the spring or bushings.
A loose pedal indicates worn bushings or a damaged shaft; replace the worn parts. If the brake lights stay on, adjust the limit bolt or the brake light switch bracket. Always use genuine Combination pedal assembly components for repairs to maintain the original pedal feel and safety.
Inspect The part at every scheduled service (every 50,000 km). Check for wear on the pedal cover, bushings, and wear sleeve. Lubricate the shaft and pivot points. Ensure all fasteners are tight and that the return spring retains adequate tension. Examine the sealing gaskets for cracks and replace if necessary. If the pedal feels rough, disassemble and clean the components. Keep the area around the pedal clean and free from debris. Regular maintenance of The part ensures consistent brake and clutch operation and extends the life of the assembly.
This Combination pedal assembly is specifically designed for the HOWO MAX 4X2 tractor and is compatible with all production years from 2018 onward. It also fits SITRAK C7H and HOWO T7H models with the same cab architecture. The kit includes both brake and clutch pedal components (where applicable). It is not compatible with older A7 or WD615 models, which have a different pedal box design. Always verify your vehicle’s VIN and pedal configuration before ordering this Combination pedal assembly.
Aftermarket pedal assemblies often use inferior materials that wear quickly, leading to increased free play, squeaks, and even pedal failure. Generic springs may lose tension, causing delayed brake release. Counterfeit bushings can crack and seize the pedal, creating a dangerous situation. Genuine HOWO Combination pedal assembly components are manufactured to SINOTRUK’s exacting standards, using certified steels, high-grade polymers, and precision-matched springs. The small additional cost of a genuine Combination pedal assembly is trivial compared to the safety risk of a malfunctioning brake or clutch pedal.
