Abstract
The present invention relates to a cushion mechanism for a brake of a bicycle, comprising a brake block, an elastomer, a sleeve, and an adjustable nut. The brake block includes an engaging end which extends through the elastomer and the sleeve and is engaged with the adjustable nut. Then the cushion mechanism is installed on a brake caliper. The cushion mechanism of the brake is constructed to prevent a sudden lock of the wheel upon an emergency brake and such an effect is achieved by mounting an elastomer between the brake block and the brake caliper. The elastomer is preset with pressure while being assembled. The preset pressure enables the elastomer to absorb a less force caused by braking when under normal braking operation; and enables the same elastomer to absorb excess force when the braking force exceeds the normal range. Thus, the braking force will not reduce, and the safety for the rider is secured.
