Brothers Trucks MSTR900DRUM Dual Reservoir Master Cylinder Drum/Drum

The Brothers Trucks MSTR900DRUM is a dual reservoir master cylinder designed specifically for classic trucks equipped with front and rear drum brake systems. This brake master cylinder provides a significant safety upgrade by converting single-reservoir systems to a safer dual-reservoir configuration, which maintains braking capability even if one circuit fails.

Key Features:

• Dual reservoir design for enhanced safety and reliability
• Engineered for drum/drum brake configurations
• Power brake applications only
• Direct fit for classic truck brake conversions
• Compatible with 1947-1959 trucks when used with appropriate mounting bracket

Installation Notes:

For 1947-1959 truck applications, this master cylinder requires the use of a master cylinder mounting bracket (part number DMC5954 or DMC5959, sold separately). This conversion significantly improves braking safety by isolating the front and rear brake circuits, ensuring that if one circuit develops a leak, the other remains functional.

Application:

This master cylinder is specifically designed for use on trucks equipped with drum brakes at both the front and rear axles, and is intended for power brake systems only. It provides modern dual-circuit braking safety for vintage truck restorations and brake system upgrades.
