Wilwood 260-12386 Side Mount Compact Brake Master Cylinder Bore - 13/16

The Wilwood 260-12386 is a side mount compact remote brake master cylinder engineered for tight-clearance installations where space is limited but full-size performance is required. With an ultra-compact 3.37-inch body length, this master cylinder delivers a full 1.12 inches of piston stroke, meeting or exceeding the stroke capacity of most standard full-size cylinders.

Key Features:

• 13/16-inch bore diameter provides precise brake pressure control
• Compact 3.37-inch body fits in restricted mounting areas
• 1.12-inch piston stroke delivers full-size cylinder performance
• Integral side mounting lugs with 3.00-inch center-to-center spacing eliminates traditional mounting flange for easier installation in tight spaces
• Top-mounted 1/8-inch NPT fluid outlet port positioned at the top radius of cylinder bore to minimize trapped air
• Enhanced fluid inlet port accepts standard reservoir (included in kit) and features 11/16-20 internal threads for custom reservoir configurations
• Black E-coated aluminum body resists corrosion and provides durable, long-lasting finish
• 2.16 inches additional clearance between mounting boss and fluid outlet compared to conventional designs

This side mount combination master cylinder is ideal for custom brake system applications, race cars, hot rods, and off-road vehicles where mounting space is at a premium but braking performance cannot be compromised. The included reservoir and corrosion-resistant finish make this a complete, ready-to-install solution.
