Parking brake manual control

The device has a control lever (3) joined on a support (1) connected to a fixed part of a vehicle. Two rods (7,8) are joined on the support and the lever to define a deformable parallelogram with the components (1,2,8,7) permitting the lever to move parallely around the support. A rod (9) returns back a force applied by a driver on the lever to a chassis of a tractor articulated on the rod (7).
