Wilwood 260-13624 Compact Remote Master Cylinder 7/8in Bore Black

Vehicle Fitment

• Semi-Universal - not tied to a specific vehicle; designed for custom brake or clutch actuation systems with limited mounting space

Fitment Notes

• This is a single-outlet (non-tandem) master cylinder, commonly used for a single-circuit brake system or as a clutch master cylinder - not a dual-circuit front/rear brake master cylinder like Wilwood's tandem models.
• No traditional mounting flange - uses integral side mounting lugs with a 3.00 in. center-to-center distance. Confirm your mounting location can accommodate this side-mount configuration before ordering.
• Uses a 3/8"-24 banjo fluid outlet - confirm your brake/clutch line fittings are compatible or budget for an adapter.
• Carries a California Proposition 65 warning.

Features

• Ultra-short 3.37 in. compact body designed for tight, limited-space installations
• Provides 2.16 in. of additional clearance between the mounting boss and the fluid outlet compared to standard-length master cylinders
• Full 1.12 in. of piston stroke - matches or exceeds the stroke capacity of most full-size master cylinders despite the compact size
• 3/8"-24 banjo outlet reduces the chance of trapped air in the system
• Enhanced fluid inlet port accepts the included standard reservoir and includes 11/16-20 internal threads for custom remote reservoir setups
• Black E-Coated aluminum body resists corrosion for a long-lasting finish

Product Description

The Wilwood 260-13624 is a compact, short-body remote master cylinder built for custom brake or clutch systems where mounting space is tight. Its ultra-short 3.37 in. body and side-mounting lug design let it fit into pedal boxes, firewalls, or engine bays where a standard-length master cylinder won't clear.

Despite the compact footprint, it delivers a full 1.12 in. of piston stroke - matching or exceeding the output of most full-size master cylinders - so builders don't have to sacrifice stroke capacity for space savings. The 3/8"-24 banjo outlet is positioned to reduce trapped air, and the enhanced fluid inlet accepts either the included standard reservoir or a custom remote reservoir setup via the 11/16-20 threads.

Because this is a single-outlet unit with a non-standard side-mount design rather than a traditional flange, it's best suited to builders already planning a custom brake or clutch actuation layout - confirm your mounting clearance, single vs. dual-circuit needs, and fluid line fitting compatibility before ordering.
