Rear wheel brake disc
On a pedelec with a disc brake, the brake disc is
screwed permanently to the wheel
hub
.
You increase brake pressure by pulling the
brake
lever
. The brake fluid is used to transfer pressure
through the brake cables 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 pushed, the brake linings are
pressed against the brake disc and the wheel
movement is decelerated until it comes to a stop.
