UPR Products 1978-1988 G-Body Manual Brake Kit with Strange 1.125" Master Cylinder

Convert your 1978-1988 GM G-Body to a lightweight manual brake system with the UPR Products Manual Brake Kit featuring a Strange Engineering 1.125-inch bore dual inline master cylinder. Designed for racing and high-performance applications, this kit eliminates the bulky factory brake booster while freeing up valuable engine bay space and reducing weight. It includes a CNC-machined billet aluminum mounting plate, adjustable brake rod, mounting hardware, and a Strange Engineering master cylinder engineered for four-wheel disc brake systems.

The billet mounting plate features a durable black anodized finish and positions the brake lines toward the fender for improved clearance. The included adjustable brake rod allows proper pedal setup while the 1.125-inch bore Strange Engineering master cylinder delivers excellent braking performance for four-wheel disc brake applications. This kit is an excellent foundation for custom manual brake conversions on race and street/strip vehicles.
