A caliper brake apparatus includes a caliper main body that is supported on a vehicle body, a brake lining that advances/retreats relative to the caliper main body and can apply a frictional force by slidingly contacting a disc, a guide plate that supports the brake lining, an anchor pin that supports the guide plate on the caliper main body such that it can freely advance/retreat, a piston that advances/retreats relative to the caliper main body and can press against the brake lining via the guide plate, a diaphragm that abuts a rear surface of the piston and defines a pressure chamber within the caliper main body and elastically deforms due to pressure of compressed air within the pressure chamber so as to move the piston, and a piston plate that supports the piston on the anchor pin such that the piston can freely slide. |
