The combined pedal assembly is the core interface for the driver to control the braking and clutch systems on the HOWO MAX 4X2 tractor. This combined pedal assembly integrates the brake pedal, clutch pedal, support plate, core shaft, push rod, all necessary fasteners, brackets, and seals into a single, precision‑engineered unit. When you choose authentic Howo Parts, this combined pedal assembly guarantees OE fitment, reliable pedal feel, and long service life. Below are detailed descriptions of every component included with this combined pedal assembly.
The plate support is a sturdy steel bracket that forms the main mounting base for the combined pedal assembly. It attaches directly to the firewall and provides the foundation for all pedal components, ensuring rigidity and proper alignment.
This pre‑assembled fastener set includes a hex head M8 bolt with a spring washer and a flat washer. It is used to secure heavy brackets and the plate support in the combined pedal assembly, providing even clamping force and resistance to loosening.
The core shaft is the main pivot pin that allows the pedals to rotate smoothly. This hardened steel shaft is precision‑ground and case‑hardened, supporting the brake and clutch pedals within the combined pedal assembly.
This is a split cotter pin used to secure the core shaft and other pivot pins. It is a safety fastener that prevents accidental disassembly of the combined pedal assembly components under vibration.
The limit bolt is an adjustable stop that controls the maximum travel of the brake pedal. It ensures that the master cylinder is not over‑stroked, protecting the brake system from damage.
These fine‑pitch M10 nuts are used to secure various studs and bolts on the combined pedal assembly. They are self‑locking and resist loosening under vibration.
The spring washer provides split‑coil locking action under bolt heads, preventing fasteners from loosening in the combined pedal assembly. It is essential for maintaining torque in high‑vibration environments.
This standard flat washer distributes load under bolt heads and nuts, protecting the combined pedal assembly brackets from embedment and ensuring consistent clamp force.
The elastic clamp is a spring‑steel clip that secures wiring or tubing to the pedal bracket. It keeps the harness away from moving parts and ensures reliable operation of the combined pedal assembly.
This smaller fastener assembly (M6 x 16) is used for attaching lighter brackets and the brake switch bracket to the combined pedal assembly, providing secure and vibration‑proof fastening.
This is a cylindrical pin used to connect the push rod to the pedal arm. It is made from hardened steel and is retained by the cotter pin, ensuring a secure linkage in the combined pedal assembly.
The brake push rod transmits the driver’s foot force from the pedal to the master cylinder. This assembly includes the rod, clevis, and adjustment nut, allowing precise pedal height and free‑play settings.
This small M4 screw is used to secure the pedal foot pad or other small components to the combined pedal assembly. It is made from corrosion‑resistant steel.
This standard M4 nut is used in conjunction with the M4 screw to secure the pedal foot pad. It is a standard hex nut with a zinc‑plated finish.
The gasket is a sealing ring placed between the pedal base and the firewall to prevent dust and moisture ingress. It ensures a clean and dry environment inside the combined pedal assembly.
The bottom plate is a protective cover that shields the underside of the pedal mechanism. It keeps debris away from moving parts and enhances the durability of the combined pedal assembly.
This bracket holds the brake light switch in the correct position so that it is actuated by the pedal arm. It is precisely shaped to ensure consistent switch engagement and reliable brake light operation.
The brake pedal assembly is the main component, comprising the pedal arm, pivot, and rubber cover. It is forged from high‑strength steel and balanced for optimal pedal feel and durability.
The clutch baffle is a metal plate that provides a stop for the clutch pedal travel. It ensures the clutch master cylinder is not over‑traveled, protecting the clutch system.
The pedal foot pad is a rubber cover with a non‑slip surface that fits over the brake pedal. It provides a comfortable and secure grip for the driver’s foot, reducing fatigue during long drives.
combined pedal assembly – genuine HOWO complete brake and clutch pedal unit for MAX 4X2
This combined pedal assembly includes every component from the support plate to the foot pad, fasteners, brackets, and seals. No extra parts needed; everything for a full pedal system replacement is here.
The combined pedal assembly uses forged steel for the pedal arm, hardened steel for the core shaft, and corrosion‑resistant fasteners. All components are built to withstand the heavy‑duty demands of truck operation.
Every bracket, pin, and washer in this combined pedal assembly is machined to SINOTRUK’s OE specifications, guaranteeing that the pedal travel, height, and feel match the original factory calibration.
With spring washers, cotter pins, and self‑locking nuts, this combined pedal assembly ensures all fasteners stay secure under the severe vibration of heavy vehicles, reducing maintenance and improving safety.
The combined pedal assembly is mounted to the firewall via the plate support. The driver presses the brake pedal, which rotates on the core shaft and transmits force through the brake push rod to the master cylinder. The limit bolt controls the maximum travel, and the brake switch bracket activates the brake lights. The clutch pedal (if present) operates through a similar linkage. The return springs (not listed but typically integrated) ensure the pedals return to the rest position. The pedal foot pad provides a non‑slip surface. All fasteners and seals ensure the assembly remains secure and protected from dust and moisture. A well‑maintained combined pedal assembly gives the driver confident, responsive control over braking and clutching.
Disconnect the battery and remove the old pedal assembly. Mount the plate support to the firewall using the M8 bolt assemblies. Install the core shaft, then attach the brake pedal assembly and clutch baffle. Connect the brake push rod to the pedal arm with the pin shaft and cotter pin. Install the limit bolt and adjust for correct pedal travel. Mount the brake switch bracket and adjust the switch. Secure all fasteners with the appropriate nuts and washers, torquing to specification. Install the bottom plate and the elastic clamp for wiring. Finally, attach the pedal foot pad and test the pedal operation. The combined pedal assembly is now ready for service.
If the pedal feels loose or has excessive free play, check the cotter pin and the push rod adjustment. Squeaking or binding indicates lack of lubrication on the core shaft or bushings – apply lithium grease. A pedal that does not return fully may have a broken return spring; inspect and replace. If the brake lights stay on, adjust the limit bolt or the switch bracket. A loose pedal often means worn bushings; replace the worn parts. Always use genuine combined pedal assembly components for repairs.
Inspect the combined pedal assembly at every scheduled service (every 50,000 km). Check the foot pad for wear, the bushings for play, and the fasteners for tightness. Lubricate the pivot points and adjust the push rod if needed. Ensure the gasket is intact and the wiring is clear. Replace any worn components promptly. Regular maintenance ensures consistent pedal feel and extends the life of the assembly.
This combined pedal assembly is 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. It covers both brake and clutch pedals. This kit is not compatible with older A7 or WD615 models. Always verify your vehicle’s VIN before ordering.
Aftermarket pedal assemblies often use inferior steel, poor‑quality fasteners, and weak springs, leading to premature wear, increased play, and even pedal failure. Genuine HOWO combined pedal assembly components are manufactured to SINOTRUK’s exacting standards, using certified materials and precision‑matched components. The small additional cost of a genuine combined pedal assembly is negligible compared to the safety risk of a malfunctioning brake or clutch pedal.
