ReMaster Master Cylinder 1in Bore Left Port Gray

The ReMaster Master Cylinder 1in Bore Left Port Gray by BAER BRAKES represents a precision-engineered hydraulic component purpose-built for high-performance brake system builds and modifications. This master cylinder serves as the heart of any custom braking setup, converting mechanical pedal input into hydraulic pressure that activates your calipers with consistency and modulation. Whether you're building a street rod, upgrading a classic muscle car, or constructing a track-focused platform, a quality master cylinder is non-negotiable for safety and pedal feel.

At 1 inch bore diameter, this master cylinder strikes a critical balance between pedal travel and braking force multiplication—a specification chosen to deliver responsive brake modulation without excessive pedal effort on manual or lightly boosted systems. The left-port configuration indicates this unit is designed for vehicle layouts requiring feed ports on the driver-side orientation, ensuring proper brake line routing without unnecessary hose runs. BAER's ReMaster line emphasizes durability and consistent performance across repeated brake cycles, with a gray finish that resists corrosion in engine bay environments. Weighing just 4.3 pounds, this compact unit (6.9 x 6.9 x 10.6 inches) fits tight fabrication spaces while maintaining full functional volume.

This master cylinder is ideal for builders integrating disc-brake conversions on older vehicles, retrofit brake upgrades on custom builds, or replacement installations on existing high-performance platforms that demand reliability. Installation requires matching the port configuration and bore size to your brake line layout, caliper piston displacement, and desired pedal ratio—a critical calculation that determines whether you achieve firm, progressive braking or mushy, travel-heavy response. Verify compatibility with your existing brake lines, booster (if equipped), and caliper specifications before purchase to ensure proper system balancing and safety performance on the street or track.
