Abstract
A unidirectional adjustment mechanism has an adjustment knob and a driving bolt screwingly connected to the adjustment knob and abutted by a right caliper body that is adapted to be secured to a left caliper body. Rotation of the adjustment knob can only drive the driving bolt in one direction due to the abutment of the right caliper body to the driving bolt, such that a brake lining attached to the driving bolt is able to be pushed toward the disk to enhance the brake effect.

A unidirectional adjustment mechanism for a disk brake for a bicycle having a left caliper body and a driving arm pivotally connected to the left caliper body, the unidirectional adjustment mechanism comprising:
- a right caliper body adapted to be secured to the left caliper body and having a through hole defined through the right caliper body;
- a driving bolt screwingly connected to the right caliper body;
- an adjustment knob rotatably connected to the right caliper body and securely connected to the driving bolt;
- and
- a braking pad securely engaged with the driving bolt, wherein the driving bolt is so configured that rotation of the adjustment knob drives the driving bolt to move in only one direction.
In a disk brake for a bicycle having a left caliper body secured to a head tube of a bicycle, a driving arm pivotally connected to the left caliper body, a driving shaft extending through the left caliper body and movable relative to the left caliper body, a first braking pad abutted by the driving shaft in such a manner that the first braking pad is movable relative to the left caliper body and a second braking pad assembly, wherein the improvements comprise:
- a first seal provided between the driving arm and the left caliper body and a second seal provided between the driving arm and the driving shaft are able to prevent pollutant from entering the left caliper body.
