4524Q Brake Shoe 4524Q · full display

Engineered from high-grade stainless steel, the 4524Q brake shoe delivers exceptional corrosion resistance and thermal stability for heavy-duty commercial vehicles. With a precise 16.5-inch by 5-inch footprint and 16 laser-calibrated rivet holes, it ensures perfect alignment with standard brake drums. The stainless steel substrate minimizes fade under repeated high-temperature braking, while the anti-squeal chamfer design reduces noise. This shoe is rigorously tested for endurance, making it a reliable choice for fleet maintenance and OEM replacements in demanding environments.

Core Advantages

  • Stainless steel construction · superior rust resistance
  • 16 precision rivet holes for balanced load distribution
  • Low-noise operation with optimized edge geometry
  • Compatible with Meritor, Dana & other major axles

Technical Specs

  • Dimensions: 16.5" × 5" (419 × 127 mm)
  • Rivet holes: 16 (dia. 8.2mm ±0.05)
  • Friction coefficient: 0.38 – 0.42 (hot)
  • Operating temp: -40°C to 450°C

Applications

Ideal for class 8 trucks, transit buses, and port tractors. The stainless steel formulation excels in coastal, humid, or winter-salting regions, preventing seizure and extending service life. Commonly used in 16.5" drum brake systems across North American and European commercial vehicle platforms.

Installation notes: Clean drum surface before fitting. Torque rivets to 25–30 N·m in a cross pattern. Allow 200–300 km of gentle braking for proper bedding. Inspect lining thickness every 10,000 km; replace if below 8mm.

Frequently Asked Questions

Q: Is the 4524Q compatible with all 16.5" drums?

Yes, it is designed to fit standard 16.5" brake drums. The 16-hole pattern matches most OEM configurations for heavy-duty trucks and buses.

Q: How does stainless steel compare to cast iron?

Stainless steel offers far better corrosion resistance and maintains consistent friction under wet or salty conditions. It also exhibits less thermal fade during prolonged downhill braking.

Q: What is the recommended replacement interval?

Inspection is recommended every 10,000 km. Replace the shoe when the friction lining wears down to 8mm or less, or if uneven wear or cracking is observed.
