Master Cylinder/Caliper Bore Size
All else being equal…
- Increasing the master cylinder bore diameter yields a shorter, harder pedal stroke with decreased clamping force at the brake pads.
- Decreasing the master cylinder bore diameter, yields a longer, softer pedal stroke with increased clamping force at brake pads.
- Increasing the caliper bore diameter, yields a longer, softer pedal stroke with increased clamping force at brake pads.
- Decreasing the caliper bore diameter yields a shorter, harder pedal stroke with decreased clamping force at the brake pads.
