The WG100440030 Brake Shoe Ass is a heavy-duty chassis braking component built for SINOTRUK Howo trucks, delivering dependable friction performance and long service life under demanding loads. As a trusted supplier of genuine Sinotruk howo parts, we provide this OEM-grade brake shoe assembly as a direct replacement for the factory original. The WG100440030 assembly ensures correct drum contact, stable braking force and reliable operation on Howo A7, T7H, HOWO 371 and HOWO 380 models.
Each unit is produced from high-strength stamped steel with a precision-bonded friction lining, a corrosion-resistant coating and accurately positioned anchor and cam contact points. The Brake Shoe Ass is manufactured to exact OEM dimensions, maintaining proper braking geometry, resisting heat, vibration, dust and moisture, and performing reliably in constant commercial truck service.
OEM WG100440030 • Drum brake shoe • Precision lining • Heat resistant • Direct OEM fit
The WG100440030 Brake Shoe Ass sits inside the brake drum on the backing plate. When the brake chamber pushes the cam or wedge, the shoe pivots outward and presses its friction lining against the rotating drum, creating the friction that slows the truck.
This WG100440030 assembly is formed to exact OEM dimensions. Anchor pin seats, cam roller contact surfaces and lining thickness all match the factory specification. Each unit is checked for correct geometry and lining bond strength before it leaves the production line.
Drivers may notice longer stopping distances, brake drag, squealing, or a pulsating pedal when a brake shoe is worn or damaged. A cracked lining, loose rivet, or contaminated friction surface also calls for immediate replacement to protect the drum and maintain safe braking.
Installing a new WG100440030 Brake Shoe Ass restores correct drum contact and braking balance. Whether the truck is used for long-haul freight, construction, mining or municipal service, this assembly is engineered to deliver consistent stopping power.
The WG100440030 Brake Shoe Ass fits SINOTRUK Howo trucks, primarily the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it mounts on the original backing plate and works with the factory anchor pins, return springs and cam rollers.
This brake shoe is used in long-haul transport, construction, mining, logging and municipal service. In these roles, it must keep correct drum contact and resist heat, dust, moisture, heavy loads and repeated braking cycles without losing friction performance.
When fitting the WG100440030, inspect the brake drum, return springs, anchor pins, cam rollers and slack adjuster. Worn or damaged hardware can shorten the life of a new brake shoe and reduce braking balance.
For fleets running multiple HOWO trucks, keeping the WG100440030 Brake Shoe Ass in stock makes brake service faster and more predictable, reducing downtime and keeping vehicles on the road.
Replacing the Brake Shoe Ass is a job for a qualified technician using basic hand tools and proper brake dust precautions. Raise and support the vehicle, then remove the wheel and brake drum to access the brake shoes.
Release the return springs and anchor pin retainers, then slide the old shoes off the backing plate. Clean the backing plate and check the anchor pins, cam rollers and drum surface for wear, scoring or corrosion.
Position the new brake shoe assembly on the backing plate and reconnect the anchor pins and return springs. Refit the drum and wheel, then adjust the slack adjuster to the OEM setting and bleed the brakes if the system was opened.
Road test the truck to confirm smooth, quiet braking. During routine service, check lining thickness and look for cracks, glazing or oil contamination. Replace the WG100440030 whenever the lining reaches the wear limit or shows damage.
The WG100440030 Brake Shoe Ass is produced in an ISO 9001-certified plant using high-strength stamped steel and non-asbestos friction material. Incoming steel and lining materials are checked for dimensions, hardness and bonding quality.
Each assembly is formed, bonded and inspected for lining adhesion, anchor pin fit, cam contact geometry and overall dimensions. The steel core is checked for coating integrity, and every unit receives a fit test before packing.
Batch samples undergo thermal cycling, salt spray, vibration and humidity testing to confirm long-term reliability in heavy-duty truck use. These checks help ensure the brake shoe performs in the tough conditions Howo trucks face every day.
The WG100440030 is covered by a 12-month warranty against material and workmanship defects. Strict quality control means every brake shoe assembly matches the fit, function and durability of the original factory part.
The WG100440030 Brake Shoe Ass helps maintain safe stopping power and stable braking on your Howo truck. A worn or damaged shoe can increase stopping distance, cause brake noise, score the drum and put the vehicle and driver at risk.
Made from quality stamped steel with a precision-bonded lining and a corrosion-resistant core, the WG100440030 offers dependable braking performance and long service life. Its direct-fit design keeps installation simple and works with the factory brake hardware.
Fleet managers gain shorter brake service times, lower maintenance costs and better vehicle availability. Owner-operators get confidence from a brake shoe that meets strict OEM standards and is backed by a 12-month warranty.
Choose the WG100440030 Brake Shoe Ass for your SINOTRUK Howo and keep your truck braking safely and reliably for the long haul.
