We're back again with our 1965 Mustang Coupe. Now recently we installed a power brake conversion kit with the dual ball master cylinder on this car with the goal of upgraded disc brakes in the future. While the factory drums are getting the job done, the discs will be a much better braking system for our car which is meant to be a nice quality driver.

Today we're going to finish off the front brake upgrades on our 1965 Coupe by installing this Disc Brake Conversion Kit from Scott Drake. This Conversion Kit from Scott Drake is going to fit your 1964 through 1966 Mustang with a six-cylinder original four lug setup. It includes brand new original style calipers, all necessary brackets, hardware, and hoses for installation, along with a set of brand new brake rotors.

For this installation you'll need a lift or a jack and jack stands, a 1/2" ratchet, 15/16" socket, 3/8" ratchet, 9/16" socket, 10mm socket, 3/8" Allen key, a 5/8" wrench, a 9/16" wrench, a 3/8" line wrench, small flathead screwdriver, channel locks, cutters, rotary tool, hammer, and safety glasses.

We're going to start by getting the car off the ground and remove both the front wheels. Then we're going to remove the dust cap from the drums and start disassembling the drum brakes. Cap off, now squeeze the cotter pin. Now we're going to remove the retaining nut. Now get the washer and bearing out, just give the drum a good tap and they'll pop right out. With everything out of the way we can shimmy the drum off.

This time we're going to attempt to disconnect the brake line. Ours has been on here probably since original, since everything is undercoated over here. This is a line you'll want to take a look at before you really begin the installation because you may want to end up replacing this. In our case we already have a new line, so we plan on replacing it, but if not you want to try to disconnect this here. Sometimes it can get stuck, end up turning the line and damaging it. Our line is beyond repair at this point so we're just going to cut it.

Now we're going to work on the retainer. Kind of the same issue here. Lots of undercoating on it, we'll get some of the way first. Then remove the clip. With the line disconnected, now we can work on removing the backing plate. It's held on by four bolts, two down here and one two up top here. With the nuts off the back of the bolts now we can remove the backing plate with the drum. We're going to clean this surface here then as well. Remove any remnants of the gasket.

Then you want to grab a disc and clean the surface. With everything off and cleaned up, now you can grab the caliper mounting bracket. Line that up with the factory holes. Okay and then tighten them down. We're ready to start assembling the rotor. You want to grab this seal, remove this metal ring, the tapered side is going to go inward. Let's put that on first. Now what you'll want to do is properly grease the bearing by getting a good amount of grease in your hand, just work it through. If you have a bearing packer, great use it. Most of you may not, this is going to be the old school way to do it. Make sure you work it in and out of the bearing so it pushes through. Once it's greased up now you can put it in the back of the rotor. Then put the seal on top of it.

Now I'm going to grease the spindle up. We'll put the rotor on, and now grease the smaller bearing. Same process. Work the grease through the bearing, makes sure it gets inside and out of all the rollers. Kind of make sure you sort of spin the rollers in your hand and push the grease through them. Now I can put the smaller bearing in. Install the washer and the retaining nut.

Okay with everything tight now we can install the cotter pin. Then finally, the grease cap. Before we install the caliper, we're going to put a little caliper grease up here in the bracket. I can put the caliper up into place. Now we're going to install the banjo bolt with the line, put one washer on each side of line. With everything else done now we can connect the brake line, put the hose up into place. Slide the retainer in, and tighten the brake line. Okay repeat the process on the other side, bleed your brakes, and your installation's finished.

If you're looking to build a quality driver like we are with your six-cylinder Mustang the Disc Brake Kit from Scott Drakes can be a perfect choice. I should mention this kit is four lug, will work with an aftermarket four lug wheel. It will not clear the original 13s. You got to have at least a 14 inch wheel and some of those won't even work, so you want to check and make sure you have the right wheels before you get the kit. If you're looking to convert to a five lug they actually make the exact same kit in a five lug will give you a lot more wheel options. Four wheel installation's pretty straightforward, taking between three and four hours and be back on the road in no time.
