A brake mechanism particularly suited for snowmobile applications wherein an engine drives a primary clutch which is in belted communication with a secondary clutch mounted to secondary clutch shaft, the secondary clutch shaft has a brake disc fixably mounted thereon and has a radial extension into a brake carrier. The brake carrier is slidable on a chain housing having a pair of brake plates including brake pads suspended between opposing carrier walls. By causing one brake pad to contact one side of the brake disc, the carrier housing is moved to bring the other brake pad into contact with the other side of the brake disc.

In combination, a snowmobile including an engine driving a primary clutch in belted communication with a secondary clutch fixably mounted to a secondary clutch shaft, said secondary clutch shaft rotatably supported within said snowmobile and having a first wheel sprocket fixably mounted at one end, said first wheel sprocket in chained communication with a second wheel sprocket fixably mounted to one end of a drive shaft rotatably supported within said snowmobile, a chain case covering said first and second sprockets, wherein the improvement comprises: a carrier having a first and second side wall aligned opposite to each other and a support plate extending generally perpendicular from said second side wall; a first brake plate including a brake pad fixably mounted thereto; a second brake plate including a brake pad fixably mounted thereto; means for supportably suspending said first and second brake pads between said first and second carrier side wall, said first brake plate being movable toward said second brake plate; biasing means for biasing said first and second brake plates away from each other; a brake disc fixably mounted around said secondary clutch shaft; said chain case having a first and second support wall in opposite spaced-apart alignment, each support wall having cooperatively aligned grooves sized to recieve the side edges of said plate section of said carrier such that a portion of said brake disc is between said brake plates in spaced-apart relationship, said carrier being slidable in said grooves of said chain case; stop means to limit the travel of said carrier in said grooves; biasing means to bias said carrier and said brake plates in a brake release condition away from said brake disc; and actuator means for moving said first brake pad against one side of said brake disc and causing said carrier to slide in said groove to cause said second brake pads to contact the other side of said disc.
