Your Guide to Brakes for Your SN95.

Ever wonder what to look for when it comes to brakes? Please take a look at the info article about brakes here. After you figure out whats important, the next step is knowing what is out there. And after you decide on your brakes, you can decide what to look for in fluid. I have some information on the fluid here. I did a lot of research when picking my brakes, and going to share that info below. The information below relates to the SN95 Mustang and the most popular brake setups.

Specs will be as follows: Caliper name (piston number), weight w/bracket (LBS), piston size (inches, 4-piston calipers will have 2, and 6-pistons will have 3), and piston area (in^2). Rotor specs are as follows: Rotor Material/style, rotor size (inches), rotor/hat Weight (LBS). All information was given to me by the respective manufacturer and/or their dealers. In some cases, the information was measured by myself, and other information was taken from online sources. FYI, floating calipers (which are the GT and Cobra (front and rear) calipers), the area is doubled. So keep that in mind.
