Hence the term..."floating disk"

Single Piston Floating Calipers are the most popular and also least costly to manufacture and service. A floating caliper "floats" or moves in a track in its support so that it can center itself over the rotor. As you apply brake pressure, the hydraulic fluid pushes in two directions. It forces the piston against the inner pad which in turn pushes against the rotor. It also pushes the caliper in the opposite direction against the outer pad, pressing it against the other side of the rotor. Floating calipers are also available on some vehicles with two pistons mounted on the same side. Two piston floating calipers are found on more expensive cars and can provide an improved braking "feel".

Same with motorcycles.

Floating calipers usually have problems sticking and have to be maintained more. The floating rotor is maintenance free. One of them has to float so you don't get pulsation and warpage.

So.... knowing that the rotor is supposed to "float", how solid should the caliper assembly be? Mine's fairly wobbly. i.e.) the bike brakes ok, but if I grab the assembly, I can wiggle it both left to right and up and down.

Any thoughts?

Thanks,

Ethan
