The pedal (10) is equipped with a stop (20), which lies against a fixed counter-stop (21) in the non-actuated basic position.

The part that remained standing was abutted with scaffolding to avoid further damage.

Alternatively the counterabutment surface may be arranged on a sliding catch (51) housed beneath the lever pad.

The abutment or counterabutment surface may be arranged on a transversely deformable, resilient engaging element (30; 43; 46) which engages the corresponding surface in tension.

The pads (7) comprise two abutment surfaces (13, 14) which are mutually inclined so as to produce, during braking, a wedging effect together with counter-abutment means (24, 25) of the calliper.

This barricade, constructed as it was and admirably buttressed, was really one of those situations where a handful of men hold a legion in check.

The barricade, constructed as it was and admirably buttressed, did indeed present one of those positions where a handful of men could defy a legion.

It is thus possible to mount the two parts according to a simple method that combines a translation closing-in movement of the two parts and a rotation movement that is interrupted when the abutment is in contact with the counter buffer.

A stop element (56, 56') of the control lever (52, 52') is supported on a counter-stop (58, 58') of the suspension arm (34, 34') so as to transmit the pivoting torque to the latter.

Within a circular base, each stone inclined outwards is clenched by the two neighbouring, so cannot tilt towards the interior of the structure.

The hood (6) includes an abutment (70) and the base includes a counter buffer (71) interacting with the abutment (70) for indexing the angular position of the base (3) relative to the hood (6) about the mounting axis.
