Rear wheel brake disc
On a bicycle with a disc brake, the brake disc is
screwed permanently to the
hub
of the wheel.
The brake lever is pulled to increase brake pressure.
The brake fluid is used to transfer pressure through
the brake lines to the cylinders in the brake calliper.
The braking force is boosted by a speed reduction and
applied to the brake linings. These apply the brake
disc mechanically. If the brake lever is pulled, the
brake linings are pressed against the brake disc, and
the movement of the wheel is decelerated until it
comes to a stop.
