Brake Calipers

There are two main types of calipers: Floating calipers and fixed calipers. There are other configurations but these are the most popular. Calipers must be rebuilt or replaced if they show signs of leaking brake fluid.
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".
Four Piston Fixed Calipers are mounted rigidly to the support and are not allowed to move. Instead, there are two pistons on each side that press the pads against the rotor. Four piston calipers have a better feel and are more efficient, but are more expensive to produce and cost more to service. This type of caliper is usually found on more expensive luxury and high performance cars.

Brembo Brake Calipers
Brembo Brake Calipers People have tried and tested various brake products from brake discs to brake pads and brake calipers, and have found the Brembo brake product range to be the best available on the market, as such, this is why we recommend Brembo's range of brake systems. As part of Brembo’s High Performance braking systems, Brembo Sport discs are premium OEM replacement units that meet or exceed all vehicle manufacturers’ specifications and tolerances. They are fully compatible with your current calipers, alloy wheels and other standard chassis components, easily mounting onto the vehicle without any problems.  
NHT Brake Calipers
NHT Brake Calipers The superior glossy powder-coat finish used by NHT provides a number of lasting benefits over painted brake calipers: Brake calipers maintain their gloss and outstanding appearance up to 500 degrees Fahrenheit, the brake caliper's powder-coat finish will not fade, even under extreme weather conditions, nothing sticks to the brake calipers: brake dust and road dirt can easily be wiped off, brake calipers are sent through a thorough final cleansing before powder coating, assuring no impurities on or inside the calipers; the powder coating process is applied before final assembly, for a markedly better finish than post-assembly spray paint.
