Wilwood Aluminum Hot Rod Tandem Master Cylinder-Black

PN: 260-8555-BK


Application: Universal and OEM Power Boosters or Direct Firewall Mount for Manual Brakes

Wildwood’s standard hot rod and muscle car MC is a premium alloy die cast large capacity body which is lightweight, looks great, and has the durability for competition that you expect from Wilwood Brakes. All versions include a black anodized, machined billet lid with a pressure balanced bellows gasket with 100% sealing against moisture invasion or fluid leakage. The mounting flange is slotted to accommodate installation on bolt centers between 3.22″ and 3.40″. For most applications its a simple bolt-on to many OE mounts including the popular Chrysler, Corvette, GM, and Ford Mustang master cylinder bolt patterns.

The body features two through-hole mounts on 6.40″ centers for side mounting to frame members or other secure elements of the chassis. Each master cylinder is configured with separate front and rear reservoir chambers and fluid outlets. There is line pressure access on both sides of the piston bore for right or left hand plumbing based on your mount location. A total piston stroke of 1.10″ is distributed at a 2:1 volume ratio between the primary and secondary chambers. Available in 7/8″, NEW 15/16″ 1.00″ or 1-1/8″ bore sizes options to match the volume and pressure requirements of nearly any application. Most power boosted systems will use the 1.125” version while most manual brake systems will use the 1.00” or smaller bores. 15/16″ and 7/8″ units come with a retained manual brake push rod. We can assist on your selection.

MC kit includes port inserts 3/8” 24, 1/2” 20 and 9/16” 18 to aid in plumbing to your hard lines as well as a bore rod spacer for power boosters. Add an adjustable prop valve below.

Black and polished versions available.
