Understanding Brake System Components and Supply Chain Challenges

The Brake System requires key parts made to high standards. Suppliers produce brake pads, brake calipers, brake rotors, and brake fluid with specific materials and checks for quality and durability.

Key components: brake pads, brake calipers, brake rotors, and brake fluid

Brake pads are made of friction material bonded to a steel plate; different materials are used depending upon the vehicle application.

Brake calipers can be single or multi-piston and made of cast iron or aluminum.

Brake rotors are primarily cast iron and used to dissipate heat.

Brake fluid must be durable and may vary, including DOT 3 and DOT 4.

Common supply chain vulnerabilities for brake components

- Raw material shortages (e.g. pig iron) that present challenges due to pricing increases or issues with suppliers.

- Single sourcing for pads, calipers, and rotors can result in elevated lead times as demand for these components can fluctuate.

- Poor quality of imported brake components may result in recalls, while shipping delays at ports or on roads may impede timely delivery.

- Changes in trade policies may affect pricing, requiring suppliers to be flexible.

Quality standards and regulatory compliance in the United States

Quality standards and regulatory compliance are necessary for brake materials sold in the U.S. The National Highway Traffic Safety Administration (NHTSA) sets safety standards for all vehicles in the U.S., which control the manufacture of brakes.

SAE and ISO identify accepted standards for designing brakes, including materials and testing (i.e., SAE 19741, ISO 2531, ISO 9437, and ISO 11242) while requiring that suppliers provide documentation demonstrating that the product meets established standards.

Lastly, brake materials must comply with the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) and the Toxic Substances Control Act (TSCA) as it relates to tracking materials used in or contained in the manufacture of brake components and the issuing of certifications demonstrating that all components being used are free from regulated substances while presenting the smallest amount of risk possible.

Supplier Selection and Strategic Sourcing for Brake Parts

Set clear goals for sourcing brake parts. Ensure theBrake Systemis ready and meets safety and performance standards while controlling costs and following U.S. laws.

Choose suppliers based on criteria like CNC machining, heat treatment, and lab tests. Assess their foundry and casting quality.

Review quality systems such as ISO 9001 and IATF 16949. Ensure they have APQP and PPAP for new products and can track parts during recalls.

Check suppliers' financial and operational strength. Seek those with diverse production and dual-sourcing to avoid failures.

Consider environmental laws when selecting suppliers. Verify their permits, chemical management, and labor practices.

Lower risks by sourcing from multiple locations, including North America, to reduce shipping times.

Compare OEM and aftermarket parts costs, including transportation and warranties, for the best choice.

Use consignment or vendor-managed inventory for repair shop parts to save money and maintain service levels.

Write contracts with clear goals and penalties, including quality standards and delivery times to ensure alignment.

Track supplier performance with metrics like delivery times and defect rates to assess their performance.

Invest in training suppliers on casting and brake part production, focusing on North America or Mexico for faster parts.

Consider relocating high-value or risky parts closer to shorten delivery times and facilitate technical changes.

Inventory Control and Logistics Optimization of Brake System Parts

It is critical to stock up on brake system parts in the service bays. The use of data to predict brake system parts needs helps to avoid running out of stock and reduces costs.

To create a demand plan, combine sales history with vehicle age and the trends produced from that data. Use telematics data to help determine when brakes may need service. Classify the parts into fast-moving and slow-moving categories.

Demand Forecasting Techniques for Brake Maintenance

Ice skating covers techniques used to forecast brake usage in maintenance and repair seasons. Start with basic forecasting, adding detail of promotions and weather forecasts to your initial forecast. Use fleet data to modify your forecast.

You should revise your forecast on a monthly basis. Increase safety stock of brake parts before winter and after a bad weather event.

Just-in-time vs. safety-stock strategies for brake pads

Just-in-time and safety stock strategies for brake pads and rotors. The advantages of using JIT for common brake pads is that it saves money and keeps the brake pads fresh, but provides an opportunity for parts to be delayed.

Using a safety stock strategy for a component that is critical to servicing vehicles is the better choice (a rotor) because it will provide confidence that you will have inventory to satisfy demand. For a component that is critical you will want to keep a higher than normal safety stock.

A Hybrid strategy is a combination of JIT for common brake pads and safety stock for rotors, balancing the amount of inventory available.

Transportation, warehousing, and damage prevention for fragile brake components

Protect parts with special packaging and clear handling rules to prevent damage.

Organize your warehouse with climate zones and train staff on handling to ensure parts arrive safely.

Choose experienced carriers and have backup routes. Set up reverse logistics for returns.
