Handbrake control and linkage – operation

When the handbrake lever is raised, a flexible cable connected to a rocker is operated. The rocker is responsible for balancing and distributing traction force beteen the two flexible links anchored to it. Its movement controls the operation of levers

on the rear brake calipers in order to engage the handbrake.

The flexible cable connected to the lever comes with a threaded end so that the travel of the control lever between the two front seats can be adjusted from inside the car.

When the handbrake lever is pulled up, the indicator switch turns on a panel warning light via the Body Computer 5505 ( Characteristic of working principle 5505

Instrument/guage electrical wiring). A warning buzzer goes off if the car sets off with the handbrake still on 5560 ( Characteristic of working

principle 5560 Instruments).

The handbrake is kept engaged by a toothed sector that prevents the handle being lowered.

When the release button is pressed, the lever is released and the tension of the links on the levers may be slackened. The levers then release the handbrake under the action of the return spring.
