The Brake Shoe Assembly 199000440031 is a fully integrated component that forms the heart of a drum brake system. Unlike purchasing a loose shoe and separate lining, this assembly comes with the high-friction lining already securely riveted to a high-strength steel shoe. This pre-assembled state is its primary advantage.
In a drum brake, this assembly is the central moving part. When hydraulic pressure is applied via the wheel cylinder, it forces the curved shoes outward, pressing the friction lining against the rotating inner surface of the brake drum. This action creates the friction necessary to slow and stop the vehicle.
The “assembly” aspect of part 199000440031 means it is designed for quick and error-free installation. It ensures the critical relationship between the shoe curvature and the lining surface is maintained exactly as Shacman engineers intended, guaranteeing optimal braking force and contact from the first application.
Opting for the complete 199000440031 assembly over individual parts delivers significant benefits. The foremost is guaranteed compatibility and performance. The friction lining is precisely matched to the shoe geometry, ensuring full and even contact with the brake drum for maximum efficiency and heat dissipation.
It drastically reduces workshop time and labor costs. Technicians no longer need to spend time riveting linings, which requires specific tools and skill. The assembly is a direct bolt-on (or clip-on) component, simplifying the repair process and minimizing vehicle downtime, a critical factor for commercial fleets.
Quality control is assured by Shacman. Every 199000440031 assembly is manufactured as a single, tested unit. This eliminates risks associated with imperfect riveting, misaligned linings, or the use of mismatched shoe and lining grades that can occur when parts are sourced separately.
Safety is paramount in braking. A pre-assembled unit ensures the lining is attached with the correct rivet tension and placement, preventing issues like lining separation under extreme heat or stress. This reliability is built-in, providing peace of mind for drivers and operators.
Because the assembly is factory-made, the critical “bedding-in” process starts from a perfect baseline. The lining surface is consistent, allowing it to properly mate with the brake drum during the initial break-in period, leading to smoother, quieter, and more effective braking from the very first mile.
The shoe itself is fabricated from robust, pressed steel, formed into a precise “T” or similar shape. This design provides the necessary structural rigidity to withstand immense braking forces without flexing or distorting, which could otherwise lead to uneven lining wear and reduced braking power.
The friction lining is a premium, heavy-duty Non-Asbestos Organic (NAO) compound. This material is engineered to provide a stable coefficient of friction, excellent heat fade resistance, and lower wear on the brake drum compared to more metallic formulations, contributing to lower total operating costs.
Riveting is performed with high-strength steel rivets. The rivet heads are set flush and act as built-in wear indicators. When the lining material wears down to within 1-2 mm of the rivet heads, the entire assembly 199000440031 must be replaced, providing a clear visual safety check.
Installation of the 199000440031 assembly should be performed by a qualified technician. The process begins with safely raising the vehicle, removing the wheel and the brake drum to access the old brake assembly. The old shoe assembly is then detached by carefully releasing the hold-down springs, pins, and the adjuster mechanism.
Before installing the new Shacman assembly, it is crucial to thoroughly clean and inspect the backing plate. Check the wheel cylinder for leaks and ensure it operates smoothly. All contact points on the backing plate where the shoe heels slide should be lightly lubricated with high-temperature brake grease.
The new 199000440031 assembly is then positioned and secured using the original hardware (springs, pins, etc.). It is vital to follow the specific spring configuration diagram for the vehicle. Once both shoes on the wheel are installed, the adjuster mechanism should be set to a preliminary setting before reinstalling the drum.
A proper break-in (or bedding) procedure is essential for the longevity and performance of the new 199000440031 Brake Shoe Assembly. This process transfers a thin, even layer of friction material from the lining onto the brake drum surface, creating an optimal mating surface for maximum contact and stopping power.
After installation, perform about 20-30 moderate brake applications from a speed of approximately 50 km/h (30 mph). Avoid coming to a complete stop during this sequence. Allow adequate cooling time between applications by driving at normal speed without braking. This generates the necessary heat gradually and evenly.
For the first 200 kilometers, avoid severe or prolonged braking whenever possible. This gentle break-in period allows the components to settle and the friction partnership to establish fully. Following this procedure will result in quieter brakes, more consistent pedal feel, and extended assembly life.
Regular visual inspection of the brake system is vital. During routine tire rotations or maintenance, the brake drum should be removed to inspect the 199000440031 assemblies. Check the thickness of the friction lining material relative to the rivet heads.
If the lining is worn to within 1-2 mm of the rivet heads, the assembly must be replaced immediately. Operating beyond this point will cause the rivets to score and gouge the brake drum, leading to unsafe braking and a much more expensive repair involving drum machining or replacement.
Also, inspect for signs of uneven wear, such as one end of the lining being more worn than the other. This can indicate a sticking wheel cylinder, seized shoe pivot points, or a misadjusted brake. These underlying issues must be corrected when installing new shoe assemblies.
The genuine Shacman 199000440031 assembly is not just a generic brake shoe; it is a system-engineered component. Its curvature, lining composition, and weight are precisely calculated to work in perfect harmony with Shacman brake drums, wheel cylinders, and the vehicle’s overall braking dynamics.
Aftermarket assemblies may have dimensional variances or use different friction materials. These discrepancies can lead to poor initial contact, noisy operation, accelerated wear on the drum, or an altered brake pedal feel that compromises the driving experience and safety.
Furthermore, using the OEM part ensures compliance with the vehicle’s original specifications and helps maintain its value and warranty status. It is the only way to guarantee that the replacement part will perform identically to the one originally fitted on the production line.
The Shacman Brake Shoe Assembly ‘199000440031 typically includes the steel brake shoe with the friction lining pre-riveted in place. Depending on the specific kit, it may also include the necessary return springs, hold-down pins, and springs for that wheel position, providing a complete solution.
Yes, always. For safety and balanced braking, you must replace brake shoe assemblies in complete axle sets (both left and right wheels on the same axle). Replacing only one side can create a dangerous braking imbalance, causing the vehicle to pull sharply to one side during stops.
The ‘199000440031 is supplied as a complete unit. While the riveted design theoretically allows for relining, in practice, it is recommended to replace the entire assembly. This ensures the structural integrity of the shoe plate and guarantees optimal performance with a factory-fresh lining.
