Message: >>>>If I upgrade from a v-brake to a disc brake on my front fork will I have to change my current brake lever? My shifter and brake lever are in one unit on my handlebars. Will I be able to use the current lever I have? Thanks,CK >>>Assuming you are using a cable actuated disc brake you should not have to change your brake lever. >> >>Cable actuated as opposed to hydrolic? >I am assuming you are asking what the difference is between cable actuated disc's and hydaulic. > Cable actuated disc brakes will use a standard brake cable to attach to the disc brake which uses a cam-like action when the cable is pulled to move one pad towards the rotor. Hydraulic disc brakes need to have a special brake lever which has a piston inside that pushes the hydraulic fluid in the line which inturn forces one or both pads in at the same time depending the the brake design. Before I purchase a front disc brake what should I know? I'm looking at an Avid Ball Bearing Disc Brake. In my searching I've found Avid BB 5 and Avid BB 7. I'm also finding a variety of rotor sizes. Thanks for the help.
