Hi eveherybody:
As some of you may know, I will change my front brakes to disck soon. The only part which is missing is booster,mc and pp valve. When I look at the different websites, some of them ask for 13 or 11 inch rear brake. How do you measure that? is it the diameter of the drum? if yes, the diameter inside (after taking the drum off) or outside? By the way mine is C20, maybe they just come with 13"? Thanks.
