Abstract:
A brake control apparatus, comprising:a) a brake disk rotatable with a wheel; b) a main brake mechanism for pressing a main friction member to said brake disk in accordance with an operation of a brake operating member to brake the wheel; c) lock detecting means for detecting a wheel condition at an instant preceding wheel locking or a wheel condition when wheel locking initiates, said lock detecting means producing a lock detection signal corresponding to the wheel condition detected; d) main brake control means for controlling said main brake mechanism to make said main brake mechanism temporarily reduce a main press force which is applied from said main friction member to said brake disk; e) a subsidiary brake mechanism for pressing a subsidiary friction member to said brake disk to brake said wheel; and f) first subsidiary brake control means for controlling said subsidiary brake mechanism to make said subsidiary brake mechanism repeat a variation cycle during the operation of said brake operating member before said first subsidiary brake control means receives said lock detection signal, said subsidiary brake mechanism increasing a subsidiary press force after reducing said subsidiary press force in said variation cycle, said subsidiary press force being applied from said subsidiary friction member to said brake disk.
