If you're looking to step up your braking game on your 1979-1984 Ford Mustang, this rear brake system is a solid choice. It comes with a beefy 6P 6-piston caliper that’s mounted to a 14-inch two-piece rotor, which is both slotted and drilled for better heat dissipation. The zinc plating helps keep things rust-free, so you can hit the road with confidence.

One thing I really appreciate about this setup is the billet backing plate. It’s not just a pretty face; it serves as the caliper mount and houses a modern park brake assembly that works way better than the old drum-in-hat systems. You'll get a more reliable parking brake experience, which is a nice touch, especially if you park on a slope.

Plus, the stainless steel brake hoses are a nice upgrade. They’re durable and keep everything compliant with D.O.T. standards, so you know you're getting quality. The calipers also come with dust and weather seals to keep the elements out. And let’s not forget about the NAS high-grade stainless hardware that holds everything together — it’s pre-assembled too, which saves you some hassle.

Fitment:

• Perfect for 1979-1984 Ford Mustang
• Supports both 5 x 4.500 and 5 x 4.750 dual wheel bolt patterns

• Everything you need is included, from hoses to fittings, so you won’t be scrambling for parts.
• Park brake cables are part of the package, making installation smoother.
• The 6061 T-6 billet aluminum hat is anodized black and securely bolted to the rotor for that extra touch of durability.
• You get high-grade U281 fine thread stainless hardware with captured nuts, and yes, the rotor comes pre-assembled.
