Product Description

Maximum Motorsports Quality
This brake line kit will make your life much easier when doing a rear disc conversion on your 1986-93 Mustang. The unique stainless steel hard lines in this kit were designed by Maximum Motorsports to fit the 1986-93 Mustang chassis with 8.8" rear end. The lines and hoses clear the stock Fox chassis bumpstops, the quad-shock brackets on the 8.8" axle housing, and a rear coil-over conversion. This kit eliminates the problems caused when trying to reuse drum brake hard lines with a disc conversion, and avoids the interference encountered when using the 1994-95 Mustang axle hard lines on a Fox chassis.

Features complete plumbing kit for 1986-93 Mustang 5.0L with rear disc conversion using four lug or five lug rotors. Kit includes all 3 rear soft hoses and stainless steel hard lines.

-Fits 1986-93 Mustang with 4 or 5 lug rear disc conversion.

5 Stars   That was easy!

Great kit. Having everything pre-bent, and all of the parts you need to get it together was awesome. Fit like a glove and awesome quality. BUT - be aware of what you're getting into before you start. I swapped the rear out of a '92, and replaced it with one from an '04. The drum brakes of the '92 have a splitter on top of the differential that the brake lines goes into, attached to a bracket that mounts to the rear. You'll need to reuse that bracket. Here's the catch - the '04 rear does not have the holes set in it to remount that bracket. That means you need to drill them out your self. Not an easy task when the rear is in the car and you have to come up from the underside of it. And the position of the hole needs to be pretty precise or the bracket will not mount properly and will a.) not match the precut/bent brake lines, and b.) interfere with the upper control arm. So the MM Conversion Plumbing Kit is well worth the money, just a word of caution before you begin.
