New 15/16” Bore Tandem Master Cylinder

NewProd Image 12 Wilwood’s 15/16” bore tandem master cylinder provides a new option for matching cylinder output to caliper capacity with custom brake upgrades on single pushrod, manual pedal brake systems.

The high-capacity body is lightweight, adds high-tech style, and has the durability for street or track. The machined billet lid captures a pressure balancing bellows gasket that fully seals moisture out and fluid in.

Standard finishes include bright media burnished for a polished look, glossy black e-coat, or plain as-cast aluminum. The master cylinders are available as stand-alone units, or can be purchased in a kit. Tandem master cylinder kits include master cylinder, combination proportioning valve, mounting bracket, pre-bent fluid tubes, and mounting hardware

    Do these fit on a 62 Pontiac Bonneville 4 door, manual drum brakes?? I also would like the proportioning valve as I may change up to discs later on?!

      Your ’62 Pontiac, Bonneville, came with a single reservoir master cylinder, and upgrading to a dual reservoir master cylinder would be a GREAT safety enhancement. Although this particular kit is a 15/16” bore and I believe for your car a 1” bore would more closely align with what you need. Not to worry, Wilwood make those too. Check out their complete line of products at: http://www.wilwood.com/ To use this master cylinder with drum brakes, you’ll need to install 10-12lb residual pressure valves on both the front and rear brake lines, after the proportioning valve. When you’re ready to upgrade to disc brakes, simply remove the residual pressure valves, connect the lines direct and you’re ready to complete your disc upgrade.

        October 29, 2011 at 12:23 pmThe design to hold a bycicle is a joke. My old jetta cold hold a full size bike in my trunk with the back seat folded down and still have my girl sit next to me. In my current Element it holds two bikes upright and my girl still sits next to me not behind me.

      Hello Gary,

      This Master Cylinder is likely not big enough for your setup. I would be inclined to use a 1-inch bore master cylinder for your particular application.

    I have a Ford 52 f1 with manual drum & brake shoes. Do you have a tandem master cylinder that works on this truck for existing drum and future front disc brake conversion?

      Hello Henk,

      Yes, smaller bore master cylinders deliver more pressure with less effort, although you will have more pedal travel than a larger bore master cylinder. for your car I would suggest either a 15/16 or 1-inch bore.
