The shackle is biased by two springs (54, 55) integral with the shackle.

The caliper (1) is designed having cooling flanges (2) extending over a part of the brake lining (7) of the caliper (1).

The clamp has a toothed pawl (33) which resists movement of the clamp along the rafter.

The brake-actuating control mechanism controls the brake caliper to provide selective frictional engagement between the brake caliper and the brake disk.

This ensures that both the lower bracket (20) and the upper bracket (18) can always be smoothly pivoted on the hinge pin (40).

The fluid medium flows through the orifice of the magnetic yoke, with the fluid medium flowing through and around the yoke.

Such a guiding member is fixed to the piece of furniture during the movement of the bracket between the first and second operating position and becomes integral to the bracket when the bracket reaches the second operating position.

The locking unit includes an integrated circuit for measuring shackle impedance through terminals capacitively coupled to the shackle.

The disk brake component (18) to be mounted adjacent the wheel is coupled to the mounting bracket preferably between the ends of the bracket (30).

The supporting bracket makes it very easy to adjust the earpieces and the latter can be easily removed from the bracket itself.

The yoke (106) is in turn rotatably coupled to a base assembly for rotation of the yoke about a vertical axis.

The slide rail and the fixed clamp are connected together as a single piece and the pressure element is separate from the fixed clamp and is fixed in a positive or non-positive fit to said fixed clamp.

As a result, the stirrup strap (16) is twisted, turning the associated stirrup (14) away from the horse.

In the clamping position the bail abuts against the stop surface (22S1) with the major axis of the bail being most preferably collinear with the major axis of the adapter.

The stopper (8) is placed above the support bracket (3), and the stopper (9) is placed below the support bracket (3).
