1979-1985 Mustang SVE Fox Body 4 Lug Rear Disc Brake Conversion

Maintain loyalty to a 4-lug setup with SVE's comprehensive 4-lug disk brake conversion for an 8.8" or 7.5" equipped 1979-85 Fox Body Mustang! SVE has adapted to find new ways to bring parts back that fell victim to discontinuation, such as the popular 93 Cobra/Turbo Coupe disc brake conversion. This kit features 1994-2004 Cobra-style rear calipers that will provide the same excellent braking performance as previous kits. For the calipers to be mounted up correctly, we include the correct brake caliper adapter brackets that complement the caliper and 10.5" rear rotors. Hub-centric rings allow the re-drilled SN95 10.5" rear rotors to center the rotor on your existing Fox Body axles properly. These parts are supported and securely in place by the long list of components we include, detailed further down the description. It's hard to beat a period-correct upgrade while retaining an OE look, which is what the SVE 4-lug disc brake conversion kit is designed to do!

Cobra Brake Calipers and 4 Lug Rotors
Remanufactured 1994-2004 SN95 Cobra-style brake calipers are supplied to provide a readily available caliper option with no digging in the junkyard. Brand new OE-style pads as also supplied that give great performance out of the box. SVE utilizes precisely redrilled 10.5" SN95 GT/V6 rear brake rotors to the proper 4x108 lug pattern your factory axles use. While this kit was in development, we found some wheel mounting flanges to be thicker than others due to variance from the factory, thus not allowing enough thread engagement on the lug nuts. To solve this issue, we have included the longer SN95 wheel studs that are still the correct 1/2x20 thread pitch to install on your existing 4-Lug Fox Body 8.8 or 7.5 rear axles.

Brake Components
To provide the appropriate amount of brake pressure to the rear brakes, along with the necessary brake line adapters needed to adapt to the factory lines on various applications. Included are the Ford Performance adjustable proportioning valve and 5.0 Resto block off the plug to correctly provide brake fluid pressure to the rear calipers. A brake line adapter fitting is included to connect your hardlines. These may or may not be used depending on your application.

SVE Quality
To demonstrate their attention to detail, SVE utilizes only the highest quality materials possible to provide an effective kit that eliminates all guesswork to properly transfer fluid to the rear brake calipers. The required replacement flared fittings are supplied to adapt the factory rear axle brake hardlines to the J&M stainless steel brake hoses. SVE includes two Mustang parking brake cables, cable guides, and E-clips to retain them to the brake caliper. New brake dust shields provide the finishing touch to make it look like a factory install!
