Wilwood 260-10279 Compact Remote Flange Mount Master Cylinder 1.00 In. Bore Die Cast Body Assembly

The Wilwood 260-10279 is a Compact Remote Flange Mount Master Cylinder Body Assembly featuring a 1.00-inch bore, engineered for high-performance street, racing, and custom brake system applications where space is at a premium. Precision machined from a high-pressure die cast premium aluminum alloy, this master cylinder body delivers full-size output capacity in an ultra-compact package.

Key Features:

• Ultra-short 3.37" compact body provides 2.16" of additional clearance between the mounting flange and the fluid outlet — ideal for tight engine bays and custom chassis builds
• 1.00" bore diameter with a full 1.12" piston stroke that meets or exceeds the stroke capacity of most full-size master cylinders
• 1/8" NPT fluid outlet port positioned at the top radius of the cylinder bore to minimize the risk of trapped air during bleeding
• High-pressure die cast aluminum alloy body with a black E-Coat finish for excellent corrosion resistance and long-lasting durability
• Flange mount design with standard mounting bolt hole configuration for straightforward installation on racing, off-road, specialty, and recreation vehicles
• Compatible with Wilwood remote reservoir kits for convenient fluid access and simplified bleeding (reservoirs sold separately)

This body assembly is sold as a bare master cylinder body (no reservoir included), making it the ideal replacement or upgrade component for existing Wilwood compact remote master cylinder installations. It is compatible with Wilwood's standard reservoir kits, including part numbers 260-7577 (4.0 oz.) and 260-8742 (10.0 oz.). Compatible with DOT 3, DOT 4, and DOT 5.1 brake fluids. Rebuild kits are available separately to restore the cylinder to factory specification.
