Overview
3.1.3
Brake system
Every S pedelec has a hydraulic brake system.
The brake fluid is in a closed hose system. If the
rider pushes the brake lever, the brake fluid
activates the brake on the wheel.
The mechanical brakes are used as an
emergency stop system and bring the S pedelec
to a halt quickly and safely in the event of an
emergency.

Rear wheel brake disc
On an S pedelec with a disc brake, the brake disc
is screwed permanently to the wheel
hub
.
The
brake lever
is pushed to increase brake
pressure. 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.
