Rear wheel cylinder size comparison

[rbkt65]

Discussion came up today about wheel cylinder size and pedal feel. What would you feel between 15/16 and 7/8 size? Front disc brakes, master cylinder piston is 1.125.

The smaller size will produce less braking force. If you were getting brake lock-up & all the parts were good, you could try a smaller wheel cyl. I doubt you would feel the difference at the pedal.
