Product Description

Mustang Rear Disc Conversion
Ditch the drum brakes on your 1987-1992 Mustang with this 5.0 Resto 4-lug disc brake conversion! This is the most complete 4-lug disc brake conversion you'll find on the market! This is a great conversion for someone that wants to retain their 4 lug wheels but upgrade to rear disc brakes. It has everything you need including the dust shields, proportioning valve, lines, calipers, pads, brake lines, E-brake cables, rotors and hardware. The factory 4-lug axles are retained for an easy installation.

Rear Brakes
The brake calipers included with this kit are the 93 Cobra/87-88 Thunderbird Turbo Coupe rear calipers. These calipers are completely disassembled, thoroughly cleaned, inspected, and then reassembled using only the highest quality materials. These calipers come with the correct brake pads so there's no hunting the parts stores for the correct pads! New drum to disc brake conversion hard lines are included!

Installation Note
Rear caliper pistons may need to be adjusted/compressed before installation.

Master Cylinder
This kit includes a 93 Cobra master cylinder to provide the appropriate fluid pressure to the rear brakes. Maximum Motorsports 3-port to 2-port conversion kit will get it connected to your stock hard lines. Included with the master cylinder is the Ford Performance adjustable proportioning valve and 5.0 Resto block off plug to correctly provide brake fluid pressure to the rear calipers.

Parking Brake Cables
Our parking brake cables are a direct replacement for the stock drum brake cables. These cables connect to the body and the calipers with no modification. The correct e-clips are included to retain them to the caliper!

Installation Note
The 1986-1998 Mustang 8.8" housing is not perfect and it will be necessary to remove a small amount of material from the rear upper corner of the housing flange. This will allow the new bracket to be rotated into position for the bolt holes to line up. See the above product image of the driver side flange for the exact location the grinding is needed.

    3 Stars   Decent budget kit
    By on 6/5/2017
    I bought this along with larger front calipers for my car. Install went mostly fine, I'm not super jazzed about how the rear axle lines are secured onto the outer part of the axle but it works well enough. Instructional video is also wrong in a couple places, do not use any shims for the brake calipers if you want them to be even close to centered on the new rotors. Also the dust shields must be installed toward the inside of the car, not on the outside face of the bracket to clear the rotor. I also used rivets for the dust shields instead of screws to give me further peace of mind about the clearance. Would also recommend different pads than what they give you and getting a stainless braided brake hose to replace your old rear hose. Much cheaper than a 5 lug conversion plus new wheels, if you're happy with your OEM wheel choices would definitely recommend this kit.

    Yes, I would recommend this item to a friend!

    3 Stars   Stops better

    Dust shield bolts had to be bolted on the back of the brake spider because the bolts hit the rotor when installed the way the instructions said, calipers could not be centered over the rotor even with all shim removed. I recommend throwing the cheap pads in the garbage, less the 300km and my wheels are black! Car does stop much better. Good economy kit

    Yes, I would recommend this item to a friend!

    2 Stars   2 stars for install, not performace
    By on 6/20/2017
    These brakes work great but are not easy to install. I had a professional shop do it. The left side bracket needed to be machined to fit. Also, the installer did not know that the washers used to center the caliper over the rotor were different thicknesses. This caused the caliper to be crooked and therefore the left brake did not work.
    The right brake did not work either. The right bracket did not need to be machined but was built so that is was offset outward so far the dust shield bolts and the caliper itself rubbed on the rotor. A test drive of about 10 feet destroyed the rotor. Grinding more than half the heads off the duct shield bolts, using no washers (zero spacing) to center the caliper, and purchasing a new rotor, remedied the right-side issues.
    Also, as other reviews have noted, the proportioning valve is useless. Adjusting to 100% pressure to the rear brakes works OK but you’re not in any danger of locking the rear brakes.
