Description

Heavy duty 1 1/8" bore master cylinder
This replacement master cylinder has twin large capacity reservoirs especially suitable for 2 or 4-wheel disc brakes. It can be used with vacuum assist brakes, hydro boost power brakes, or even manual brakes**. This master has the common 3/8"-24 fittings on both sides so you can route your brakes lines as you see fit. Included are plugs to block off the unused ports.

If you do not want to worry about adapting your existing hoses/lines, upgrade to our #3077 hose kit seen to the right on this page.

Included items: Bench bleeding kit, port plugs, and bore adapter for short-rod boosters.

**Note: Manual brake systems require the deeper piston back bore to safely accommodate their longer pedal rods. Therefore ALL manual installations require that the "bore adapter" (see image above) be left out, or removed if already installed, to allow safe rod engagement. In manual setups more pedal pressure will be required due to the larger than stock bore of this master cylinder.

lid is extremely hard to remove requires prying off the hold down bracket with a screwdriver to remove cap other than that works great

Heavy duty is exactly what you get. It is rock solid, has large fluid capacity, a great cap design, and most importantly will stop that wild horse in its tracks! Awesome product!

Good looking and excellent performance. Did the job on a 66 with 4 wheel drum brakes. Big difference in stopping power!

Great MC
