Master Cylinder Short Side Mount 1in

The Wilwood Master Cylinder Short Side Mount 1in is a compact brake master cylinder engineered for precision hydraulic braking systems in high-performance and off-road vehicles. With a 1-inch bore and 1.120-inch stroke, this direct or remote side-reservoir master cylinder delivers reliable pressure modulation for hydraulic brake circuits requiring responsive pedal feel and repeatable stopping power. Built from aluminum construction with black paint finish, the unit combines lightweight design with corrosion resistance suitable for demanding driving environments.

The short side-mount configuration positions the reservoir perpendicular to the cylinder body, optimizing packaging in tight engine bays and custom installations where traditional top-mount cylinders conflict with headers, intake manifolds, or frame geometry. The 1-inch bore and 1.120-inch stroke are sized for brake systems requiring moderate fluid displacement per pedal travel—ideal for manual-operated circuits and applications where driver feedback and controlled line pressure are priorities. This master cylinder ships as a complete kit, including all necessary seals, springs, and hardware for direct installation. Wilwood's engineering ensures consistent fluid displacement across thermal cycling and sustained braking loads, critical for vehicles operating in rally, off-road, or motorsport duty.

Users installing a Wilwood master cylinder for the first time should verify bore and stroke compatibility with their existing brake line routing, caliper displacement, and pedal ratio. The side-reservoir design permits flexible mounting angles and works with both gravity-feed and pressurized reservoir setups. Builders restoring or upgrading brake systems in classic vehicles, building custom hot rods, or retrofitting manual brakes into vehicles previously equipped with power-assist benefit from Wilwood's reputation for reliable hydraulic control and durability in unforgiving conditions.
