If you are looking for increased braking performance to match your OE Cobra style front brakes, this rear brake caliper bracket kit is for you! This kit is used to install 11.65" rear Cobra rear brakes onto your 1994-04 Mustang GT or V6. From the factory, Cobra, Bullitt, and Mach 1 Mustangs came with larger vented rear brakes compared to their V6 and GT siblings. These rotors measure over 1" larger than the factory Mustang brakes and provide additional cooling with their cooling vanes.

If you’ve already upgraded the front braking components to a Cobra-style setup on your 1994 to 2004 Mustang and are wanting even more braking performance, your next step is converting the rear brake components to Cobra-style.

We will be using the M2300M Cobra rear brake conversion kit from Ford Performance, gloss black SVE Cobra-style rear calipers, and braided stainless rear brake hoses. The M2300M kit includes caliper adapter brackets, rotors, brake dust shields with hardware and anti-moan braces. These components are specific to the 11.65-inch Cobra rear rotor. This kit is designed to work with 1994 to 2004 solid axle Mustang GTs and requires a Cobra-style caliper, which is why we’re using the SVE caliper. You can use a rear caliper from a 94-04 Cobra, 01 Bullitt, or an 03/04 Mach 1.

This install will take roughly 3-4 hours to complete.

    58. If you’re using a take-off caliper, it’s important that the caliper piston is fully compressed before installation. This is done by using a piston compressing tool that has an adapter plate with drive pins. These drive pins align with the two notches in the caliper piston.

    60. Assemble the tool and then rotate clockwise to compress the piston. Whenever the piston is fully compressed, ensure that the two notches are oriented in the 12 and 6 o clock positions in relation to the face of the caliper. If it isn’t, simply rotate the piston counter-clockwise until the notches are in the correct position. This is to ensure the locating tab on the brake pad is properly seated during reassembly.

Landan reviews the Ford Performance M-2300-M Cobra Rear Brake Conversion with SVE Cobra style calipers before installing them on our 2004 Mustang gt project car Keeping Comp!

If you are looking for increased braking performance to match your OE Cobra style front brakes, this rear brake caliper bracket kit is for you! This kit is used to install 11.65" rear Cobra rear brakes onto your 1994-04 Mustang GT or V6. From the factory, Cobra, Bullitt, and Mach 1 Mustangs came with larger vented rear brakes compared to their V6 and GT siblings. These rotors measure over 1" larger than the factory Mustang brakes and provide additional cooling with their cooling vanes.

These SVE Black Rear Cobra brake calipers are a direct replacement for 1994-2004 Cobra's but can be a great upgrade to a 1994-2004 Mustang GT or V6 with minor modification. They can also be used to convert a 1979-1993 Foxbody mustang to rear disc brakes using the disc brake conversion brackets LRS-2100A-K.

Ford Performance Cobra Rear Brake Conversion notes:
-Will not work as a Fox rear disc conversion.
-Requires Cobra specific brake calipers. GT/V6 calipers will not work with these rotors.

SVE Rear caliper notes:
-These rear calipers are a direct fit replacement for 94-04 Mustang Cobra.
-These rear calipers work for 94-04 GT and V6, retaining the GT/V6 rotor and axle flange bracket if the included Cobra pads are swapped out for GT/V6 pads.
-If using these calipers to upgrade a GT/V6 to 11.65" Cobra rotors, you will need the Cobra specific axle flange bracket. This bracket is available new in kit # M2300M, or you will have to source them used individually.
