A multi-piston-dedicated heat dissipating caliper cover with easy installation includes a caliper cover body, a fixing assembly and at least two first fixing bolts. One side edge of the caliper cover body extends toward a side to form a first arc-shaped side plate, and the other side edge of the caliper cover body extends toward a side to form a second arc-shaped side plate. The fixing assembly includes a bolt fixing sheet and a positioning sheet, one end of the positioning sheet is connected with the bolt fixing sheet through a second fixing bolt, and the other end of the positioning sheet passes through a strip-shaped hole and then is inserted into a slot at a top of a brake caliper. By disposing the heat dissipating silicone sheet, a contact area is increased, which allows the heat generated by the brake caliper to be quickly transferred to the caliper cover.
