A reinforced booster for a bicycle brake is substantially U-shaped and attached to the pivot points of the bicycle brake to increase its braking power. The reinforced booster has a substantially U-shaped member with inner and outer peripheral edges which have high strength strands of fiber attached thereto for increasing the strength of the U-shaped member. The strands of fibers extend longitudinally along the peripheral edges of the U-shaped member. Preferably, the U-shaped member is constructed of a plurality of sheets of a non-metallic material. For example, a plurality of carbon sheets can be used to form the U-shaped member. The strands of fibers attached to the peripheral edges of the U-shaped member can be, for example, carbon fibers, polyamide fibers, glass fibers or other reinforced plastic fibers. The free ends of the booster has mounting holes which are preferably formed by strands of fibers.
