ABSTRACT:
A brake control apparatus includes a bracket, a brake lever pivoted to the bracket via a lever shaft and a lever spring for urging the brake lever to its home position relative to the bracket. The lever spring has first and second spring legs engageable respectively with the bracket and the brake lever and a coil portion disposed between the first and second spring legs. A return movement of the brake lever to its home position relative to the bracket is realized by flexion of a radial center line of the coil portion of the lever spring. With this control apparatus, the lever spring can provide substantially constant urging force regardless of the pivot amount of the brake lever and the lever spring does not produce unpleasant creaking noises in the course of a braking operation.
