This Excel spreadsheet calculates the force on brake pads for a 50kg pedal pressure. You will need to know or measure:
- Master cylinder diameter
- Caliper piston diameter
- No of pressurised piston faces (ie 2 for a single piston floating caliper coz the same pressure acts both ways)
- Brake pedal length (pivot to pad)
- Brake pedal length (pivot to clevis pin through the master cylinder pushrod)
- 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!
