Brake calculator spreadsheet

This Excel spreadsheet calculates the  force on brake pads for a 50kg pedal pressure.  You will need to know or measure:

  1. Master cylinder diameter
  2. Caliper piston diameter
  3. No of pressurised piston faces (ie 2 for a single piston floating caliper coz the same pressure acts both ways)
  4. Brake pedal length (pivot to pad)
  5. Brake pedal length (pivot to clevis pin through the master cylinder pushrod)
  6. Servo diameter

Just download it to your own machine, open it up, then  insert the black numbers and it calculates the blue ones.

I hope it helps…use at your own risk!
