⚙️ FAQ Page – Brake & Transmission Engineering
Brake System Engineering
Q: What are the key differences between OEM and performance brake pads? A: Performance brake pads utilize advanced friction compounds engineered for higher operating temperatures and improved modulation. Our engineering-grade pads feature: ceramic matrix compounds rated to 1400°F, progressive friction curves for consistent pedal feel, and reduced brake dust through optimized abrasive formulations. Coefficient of friction typically ranges from 0.35-0.45 compared to OEM’s 0.25-0.35 range.
Q: How do I calculate proper brake rotor thickness for my application? A: Minimum rotor thickness is determined by thermal mass requirements and structural integrity. Our engineering formula considers: vehicle weight × deceleration rate × safety factor (1.5) / rotor swept area. For example, a 3,500 lb vehicle requires minimum 32mm rotor thickness for track use. We provide detailed thermal analysis reports with all brake system specifications.
Q: What causes brake fade and how can it be prevented? A: Brake fade occurs when friction material exceeds optimal operating temperature, causing friction coefficient degradation. Prevention requires: proper thermal management through ducting, fade-resistant friction compounds, adequate thermal mass in rotors, and proper bed-in procedures. Our brake systems include comprehensive thermal modeling data and cooling requirements.
Clutch and Transmission Systems
Q: How do I determine the correct clutch torque capacity for my engine? A: Clutch torque capacity should exceed engine torque by 20-40% safety margin. Calculate using: Engine Torque × Torque Multiplication Factor × Safety Factor. For turbocharged applications, multiply peak torque by 1.3-1.5 to account for torque spikes. Our clutch engineering team provides detailed capacity calculations and material specifications for each application.
Q: What’s the difference between organic, ceramic, and metallic clutch materials? A: Each material offers distinct characteristics:
- Organic: Smooth engagement, quiet operation, limited to 350 ft-lbs
- Ceramic: Higher temperature resistance, firm engagement, 600+ ft-lbs capacity
- Metallic: Maximum durability, aggressive engagement, 800+ ft-lbs capacity Material selection depends on application requirements, acceptable engagement characteristics, and power levels.
Q: Why do performance clutches require different flywheel specifications? A: Performance clutches generate higher clamp loads requiring reinforced flywheel contact surfaces. Minimum flywheel specifications include: step height accuracy within 0.001″, surface finish 60-125 RA, and proper heat treatment for dimensional stability. Our flywheels undergo precision machining and stress-relief procedures to ensure optimal clutch performance.
Hydraulic System Engineering
Q: How do I calculate brake fluid boiling point requirements? A: Brake fluid boiling point must exceed maximum caliper temperatures plus 50°F safety margin. Typical requirements:
- Street applications: DOT 3 (401°F dry boiling point)
- Performance driving: DOT 4 (446°F dry boiling point)
- Racing applications: DOT 5.1 (518°F dry boiling point) Wet boiling points drop significantly, requiring annual fluid replacement for optimal performance.
Q: What causes brake pedal sponginess in performance applications? A: Sponginess results from: air entrainment in hydraulic lines, brake fluid vaporization under heat, flex in rubber brake lines, or caliper deflection under pressure. Solutions include: proper bleeding procedures, high-temperature brake fluid, stainless steel braided lines, and reinforced caliper designs. Our hydraulic systems include detailed pressure testing protocols.
