1105333501159: Durable Rear Brake Shoe Set for SINOTRUK Howo Safety

Core Function in the Drum Brake System

The Rear Brake Shoe, part number 1105333501159, is the central friction component in a drum brake assembly. Typically, two shoes are mounted on a backing plate inside the brake drum. When the brake pedal is pressed, hydraulic pressure expands the wheel cylinder.

This forces the curved shoes outward against the inner surface of the rotating brake drum. The resulting friction converts the vehicle’s kinetic energy into heat, slowing the wheel. The genuine 1105333501159 shoe provides a high-friction surface for this contact.

Its design and material are crucial for effective and predictable braking. The shoe must withstand immense heat and pressure without fading. A worn or inferior shoe compromises stopping distance and vehicle safety. The genuine part ensures performance.

Symptoms of Worn Brake Shoes

Worn rear brake shoes, part 1105333501159, present clear warning signs. Reduced braking efficiency is the primary symptom. The vehicle requires a longer distance to stop, or the pedal feels soft and travels closer to the floor.

A scraping or grinding noise from the rear wheels, especially when not braking, indicates the lining is worn down to the metal shoe. The parking brake may not hold the vehicle securely on an incline. This is a critical safety issue.

The vehicle may pull to one side during braking if one side’s shoes are more worn. Visible brake dust leakage from the rear drum backing plate can be a sign. Any of these symptoms require immediate inspection of the 1105333501159 shoes.

Never ignore brake warning signs. Driving with severely worn shoes can damage the brake drum itself. This leads to a much more expensive repair. Prompt replacement with genuine 1105333501159 shoes restores safe braking performance.

Replacement and Service Procedure

Replacing rear drum brake shoes is a detailed mechanical task. Safely lift and support the truck, removing the rear wheel. The brake drum must be removed, which may require backing off the automatic adjuster through an access hole.

Once the drum is off, photograph the spring and hardware configuration. Use proper brake spring tools to carefully remove the return springs, hold-down springs, and pins. Note the position of the primary and secondary shoes (1105333501159).

Disconnect the parking brake cable from the lever on the shoe. Remove the old shoes and hardware. Clean the backing plate thoroughly and apply a thin layer of high-temperature brake grease on contact points. Never get grease on the lining.

Install the new genuine 1105333501159 shoe set, following the photographed pattern. Reconnect the parking brake cable. Install all new springs and hardware from a brake hardware kit. Adjust the brakes, reinstall the drum and wheel, and test.

Importance of Regular Brake Inspection

Brakes are the most critical safety system on a vehicle. Regular inspection of the 1105333501159 shoes is non-negotiable. Check brake lining thickness during tire rotations or scheduled maintenance services.

Listen for any unusual noises and pay attention to changes in pedal feel. Address minor issues immediately before they become major safety hazards. Always replace brake shoes in axle sets (both sides) to ensure balanced braking.

Using genuine 1105333501159 parts guarantees that the friction material meets the vehicle’s original specifications. This ensures compatibility with the brake drum and provides the designed stopping power and heat management.

Why the Genuine OEM Shoe is Essential

The genuine 1105333501159 brake shoe is engineered to exact curvature and dimensions. It matches the specific brake drum profile of your SINOTRUK Howo. This ensures maximum contact area for effective braking and even wear.

The friction compound is formulated for the correct balance of stopping power, fade resistance, and drum compatibility. Non-genuine shoes may use harder materials that wear the drum quickly or softer ones that wear out too fast.

The steel shoe plate on the genuine 1105333501159 is robust and resistant to distortion. It provides a secure mounting point for all springs and hardware. For safety-critical components, OEM quality is the only acceptable choice.

Conclusion: Invest in Safety with 1105333501159

The Rear Brake Shoe, OEM number 1105333501159, is a fundamental safety component that directly impacts your ability to stop your truck safely and predictably. Its condition is paramount to driver, cargo, and public safety.

Choosing the genuine 1105333501159 part guarantees the correct fit, material quality, and performance engineered for your SINOTRUK Howo. Ensure the highest standard of braking reliability by adhering to a strict inspection schedule and using only authentic OEM brake components.
