Disc Brake Conversion 79-86 Mustang Rear 5 Lug

The Disc Brake Conversion 79-86 Mustang Rear 5 Lug by LEED BRAKES transforms your classic Mustang's stopping power from aging drum brakes to modern, responsive disc technology. Built for first-generation Fox-body and earlier Mustang platforms, this conversion kit addresses a critical performance gap that affects both safety and driving confidence. Whether you're restoring a 1979–1986 model or upgrading a modified street machine, rear disc conversion unlocks superior heat dissipation, shorter stopping distances, and the reliability demanded by modern traffic conditions.

This rear conversion features five-lug compatibility, engineered to bolt onto your existing 5-lug axle configuration without requiring custom fabrication or hub changes. The kit includes pre-engineered calipers, rotor carriers, and brake pads calibrated for balanced front-to-rear bias—essential for preventing rear lock-up during hard stops. LEED BRAKES' engineering ensures that the conversion maintains OEM-style proportioning while delivering the thermal capacity needed for sustained performance driving, autocross events, or weekend spirited cruising. The modular design allows for straightforward installation alongside your factory or upgraded front brake system.

Enthusiasts restoring late-1970s through mid-1980s Mustangs will find this conversion essential for modern safety and control, particularly when paired with upgraded front disc brakes and performance suspension modifications. The 5-lug specification fits a wide range of popular rear axle assemblies found in 1979–1986 Mustang production, making this an ideal choice for both stock restorations and restomod builds. Installation requires basic mechanical skill and standard hand tools, though professional installation is recommended to ensure proper brake fluid bleed procedures and line routing. This conversion significantly improves driver confidence and vehicle dynamics for anyone serious about maximizing their classic Mustang's potential.
