Show original supplier description

The TBM Brakes 1988.5-1993 S10 Sonoma Blazer Manual Brake Master Cylinder Conversion Kit allows for a conversion to manual braking systems. Engineered for performance, this kit utilizes a Strange Engineering Dual Mopar Master Cylinder with a 1.032" bore, specifically chosen to optimize the manual brake setup. The master cylinder mount is precision-machined from 6061 aluminum billet, ensuring durability and a custom fit. A 4130 chromoly pushrod of custom length is included to ensure the pushrod is correctly positioned for optimal function. This kit is designed with a 6:1 pedal ratio, which is recommended for manual brake systems to provide responsive control. Installation requires drilling a new hole in the vehicle's brake pedal to accommodate the pushrod. Master cylinder fittings and necessary hardware are included to complete the conversion. Note that this product is intended for racing use only and is not legal for road use.
