What is a tandem master cylinder?

A tandem master cylinder has two separate hydraulic circuits. This means if one circuit has a leak or failure, the other circuit can still operate, providing some braking ability.

Why is the bore size important?

The bore size of the master cylinder affects the amount of hydraulic pressure generated and the volume of fluid displaced. A 7/8 inch bore is a common choice for custom builds, balancing pressure and volume for various caliper setups.

What does 'bench bleeding' mean?

Bench bleeding is the process of removing air from the master cylinder before it's installed in the vehicle. This is typically done by installing fittings in the outlet ports and running brake fluid back into the reservoir, ensuring a solid pedal feel.

Product Details

If you're building a custom brake system or upgrading an older setup, a reliable master cylinder is key. This Wilwood Compact Tandem Master Cylinder is designed for those situations where space is tight but you still need dependable stopping power. Its compact size makes it a popular choice for hot rods, custom builds, and vehicles where fitting a standard master cylinder is a challenge.

This unit features a 7/8 inch bore, which is a common size for many custom applications, offering a good balance for actuating a variety of brake calipers. The tandem (dual circuit) design is a critical safety feature, meaning if one brake circuit were to fail, the other would still function, providing a level of redundancy. It's made from die-cast aluminum for a good strength-to-weight ratio and comes with a pushrod ready for installation. The black finish gives it a clean, understated look that blends well into most engine bays.

When setting up a new master cylinder, remember to properly bench bleed it before connecting the brake lines to ensure you remove all air from the system. This Wilwood unit is a solid option for anyone looking to take control of their braking performance with a compact and reliable component.
