Several Disk Brake schematic figures and calculations are displayed below:

disk_brake_pedal_box_figure_mv

Pedal Box schematic

•Pedal force (FP) = disk_brake_pedal_force_equ_mv
•Pedal ratio (PR) = disk_brake_pedal_ratio_equ_mv
•Force at master cylinder mount point (FMC) = PR * FP
•Brake bias (BB) = disk_brake_brake_bias_equ_mv
•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

Brake Disk schematic

Normal force by brake pad on front brake Disk:

• disk_brake_fbp_lr_area_equ_mv
• disk_brake_fmax_brake_pad_l_equ_mv
• disk_brake_ffr_step_equ_mv

disk_brake_friction_coeff_equ_mv is friction coefficient between brake Disk and brake pad

disk_brake_ang_velocity_wheel_equ_mv is angular velocity of the wheel

disk_brake_frctn_frc_vs_whl_ang_spd_mv

Friction Force versus Wheel Angular Speed

•Friction torque on the brake Disk = disk_brake_fric_trque_equ_mv
