Compact Master Cylinder .625in

The Wilwood Compact Master Cylinder .625in (model 260-6087) is a precision-engineered hydraulic brake component designed for high-performance automotive applications where space constraints demand a compact footprint without compromising stopping power. Built by Wilwood, a leader in brake system innovation, this master cylinder serves custom builders, drag racers, road course competitors, and street rod enthusiasts who require reliable brake modulation in tight engine compartments.

Whether you're fabricating a custom brake system or upgrading a legacy vehicle build, this compact unit delivers consistent pressure delivery across multiple brake circuits. The .625-inch bore diameter positions this master cylinder in the compact range, making it ideal for lightweight vehicles, custom applications, or installations where traditional full-size units won't fit. Wilwood's engineering ensures rapid fluid displacement and pressure buildup, translating to responsive brake pedal feel and superior modulation—critical factors when coordinating brake balance in performance driving.

The compact form factor (5.9 × 3.2 × 8.7 inches) integrates seamlessly into custom brackets and firewall-mounted configurations, while the verified weight of 1.05 lbs keeps unsprung mass minimal. Precision-machined internals guarantee repeatable performance across repeated brake events, essential for track use or demanding street applications where thermal stability matters. This master cylinder is an excellent choice for those looking to enhance their vehicle's braking performance.
