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.
Based on this information above, a stock A body caliper piston is 2.50" diameter, and a stock A body manual master cylinder is 1-1/32" diameter bore. This is factory setup.
Cordoba brake pistons are 2.75" diameter. So according to this above information from DrDiffs website, if i use an aluminum 1-1/32" bore master cylinder in a manual brake config, which is the same as stock A body manual disc, along with 1/4" larger than stock A body piston calipers off a cordoba it should yield a softer pedal, with a firmer clamping force.
