5.1.2.1 Disc brake
The brake discs are fastened to the wheel
hubs, with the corresponding brake calliper
fastened to the frame or front fork (see
“Illustr.: Disc brake”). The brake pads are
located inside the brake calliper. When the
brake lever is operated, the brake pads are
pressed against the brake disc and brake the
wheel.
5.1.2.2 Rim brake
Rim brakes are fastened to the front fork or rear frame. When operated, the brake block
holders are pressed against the braking surface of the rim sidewall to brake the wheel
(see “Illustr.: Mechanical rim brakes” and “Illustr.: Hydraulic rim brake”).
Depending on the brake design, mechanical rim brakes may be equipped with a brake
force modulator. The brake force modulator partially regulates the brake lever force at
the front and prevents the front wheel locking up. The brake force modulator is installed
between the brake lever and rim brake.
