In many different spots.



It all depends on which caliper and master cylinder you have.

Where would be a good reference to look up the sizes for a stock 1979 CX500C?

I'm looking at ebay because bike bandit doesn't seem to have the stuff i'm thinking of listed but what I'm seeing is a 42.8 piston and I thought the MC was 12mm.

Thanks, the manual on the dropio site wasn't any help on a '79 when they went to the square reservoir.

Did you look in Chapters 21 and 22, the '79 addenda?

Didn't look close enough.



14mm MC = area of 154 + 42.8mm caliper = area of 1439



Ratio: 1439/154 = 9.34



15.87mm MC = area of 198 + [2 times] 30mm caliper (area = 707) = 1414



Ratio: 1414/198 = 7.14
