Brakes are used on Mini 4WD tracks to scrub off speed before slopes, drops and other sections where an out-of-control car would otherwise fly off the course. This set supplies two different types of adhesive-backed sponge, pre-cut into 5mm-wide strips, along with stays shaped to hold the sponge firmly in place so it resists peeling off and causes less speed loss when it brushes against turf-textured track sections. It is compatible with FM-A and MS Chassis cars (when combined with Item 15430, the FRP Rear Multi Roller Setting Stay) as well as Super-II, AR and MA Chassis cars directly.
