Exactly What Is A Swinging Caliper

While the traditional floating caliper reigns supreme, it does gain some swinging corporation.

Swinging calipers aren't largely infrequent Sufficiently to qualify as an automotive oddity -- BMW's been using them for elderliness -- on the contrary they certainly achieve fall out of the gauge for most cars. The swinging caliper offers a figure of advantages over traditional floating calipers, nevertheless lacks the compact versatility of its added straightforward siblings.

Standard Floating Calipers

A floating brake caliper is one that moves with adoration to the brake rotor, and a swinging caliper is one type of floating caliper. On most cars, the brake caliper connects to the rotate hub with a duo Of long standing, horizontal through-bolts. Holes in the caliper object permit the caliper to modification through and outward respective to the motorcar's protest. As the inside caliper piston presses down, it both pushes its pad against the brake rotor and pulls the outer pad in the object of the caliper inflowing.

Standard Floating Caliper Issues

Pros and Cons

Except practical considerations like packaging, weight and unit strength, the swinging caliper doesn't have any drawbacks of note. It does exactly what it's supposed to do; namely, to reduce pad wear and even out braking pressure on the rotor. The swinging caliper's physical size is its biggest enemy.

Swinging Calipers

Instead of a twosome of horizontal bolts that grant the caliper to step straight in and elsewhere respective to the car body, a swinging caliper utilizes a single, vertical pivot bolt located somewhere behind the axle centerline. When the driver presses the brakes, the brake piston pushes on the inside piston and rotates the whole caliper inward, when viewed from the top. Because the swinging caliper's piston angle changes relative to the rotor, this design uses wedge-shaped pads that are narrower in the rear on the outside and narrower on the front on the inside.

While Car manufacturers far-reaching ago standardized the floating caliper, it does include at least one big enigma. As the brake slave cylinder presses on the pad, it both exerts also strength on the centre of the pad than the ends and exerts else braking vigour on the inside pad than the away. This can agency blistering spotting on the pad and uneven pad wear, which hurts the brakes' hot-temperature performance and reduces pad and rotor longevity.

This arrangement requires a large, horizontal mounting plate that encircles the top of the rotor. Though not an insurmountable obstacle, it is one that limits the caliper's applications. That aside, most engineers and drivers feel more comfortable with two bolts holding the caliper than they do one.
