136513 Wilwood Tandem Remote Master Cylinder for High-Performance Brake Systems

Mismatched bore sizes, leaking fluid circuits, or un-adjustable rear pressure balances can lead to erratic braking performance, vehicle pulling, and compromised safety. The Wilwood 136513 Remote Tandem Master Cylinder offers a premium, independent circuit design that ensures complete separation between front and rear hydraulic channels, eliminating cross-contamination and uneven pressure distribution. Engineered from high-pressure die cast aluminum, this master cylinder provides a lightweight, durable solution optimized for both classic and modern vehicle upgrades, delivering consistent pedal feel and reliable operation.

This master cylinder is available in two bore sizes: 1.00 inch and 1-1/8 inch, catering to a wide range of manual and power-assisted brake applications. The 1-inch bore is suitable for manual and power brakes without a pushrod, while the 1-1/8 inch bore is primarily designed for power brake systems, including vacuum or hydraulic assist configurations. Both variants feature fluid outlet ports on both sides of the bore, with mounting flange compatibility from 3.22 inches to 3.40 inches, fitting most domestic vehicles from the mid-1960s onward. The stroke is set at 1.12 inches, with a 2:1 volume ratio between primary and secondary chambers, ensuring optimal brake modulation and pedal response.

Weighing only 3 pounds, this master cylinder offers a 75% weight reduction compared to traditional cast iron units, making it ideal for performance builds and fleet applications where weight savings are critical. The high-pressure die cast construction guarantees structural integrity under demanding conditions, providing a reliable foundation for high-performance brake systems. For enhanced system integration, Wilwood offers a retrofit combination proportioning valve kit, including brackets and stainless lines, specifically designed for use with these master cylinders (see PN 260-14248). Proper installation and setup are essential for achieving optimal brake balance and safety, making this master cylinder a top choice for professional technicians and fleet managers seeking precision and durability.

Ensure compatibility by measuring your plumbing clearance, line fitting sizes, and pedal pushrod thread spacing before ordering, as custom bracket configurations vary across classic and fleet vehicles.
