Wilwood High Volume Tandem Master Cylinder - 7/8in Bore Ball Burnished-W/Pushrod

If you're setting up a manual brake system or upgrading an older setup on your domestic car or truck, a reliable master cylinder is key. This Wilwood tandem master cylinder, with its 7/8-inch bore, is built to handle the demands of manual applications, ensuring consistent hydraulic pressure to your brakes. It comes complete with a pushrod, ready for installation.

Wilwood machines these master cylinders from high-pressure die castings, resulting in a unit that weighs only 3 pounds. That's a significant weight saving, often around 75% less than traditional cast iron master cylinders, which can make a difference in overall vehicle weight. The design includes fluid outlet ports on both sides, offering flexibility during installation, and it's made to fit common domestic mount flanges from the mid-1960s to today. The internal design features a 1.10-inch stroke and a 2:1 volume ratio between the primary and secondary chambers, crucial for proper brake function in manual systems.

For a complete brake system setup, Wilwood offers a combination proportioning valve kit that works specifically with this master cylinder. You can find it under part numbers 260-13190 or 220-13189 for a retrofit kit.
