Schematic

Several Disk Brake schematic figures and calculations are displayed below:


Figure 1. Pedal Box Schematic
  • Pedal force (FP) =
  • Pedal ratio (PR) =
  • Force at master cylinder mount point (FMC) = PR * FP
  • Brake bias (BB) =
  • Force in front master cylinder, FFront = BB * FMC
  • Pressure in front brake line, PFront = KBrake boost * FFront/AreaMC_front
  • Force in rear master cylinder, FRear = (1 - BB) * FMC
  • Pressure in rear brake line, PRear = KBrake boost * FRear/AreaMC_rear


Figure 2. Front Brakes Schematic


Figure 3. Brake Disk Schematic
Normal force by brake pad on front brake Disk:
  • is friction coefficient between brake Disk and brake pad
  • is angular velocity of the wheel


    Figure 4. Friction Force versus Wheel Angular Speed
  • Friction torque on the brake Disk =
