Wilwood Polished 7/8” Bore Compact Tandem Brake Master Cylinder with a Proportioning Valve.

The Polished Wilwood Compact Tandem Brake Master Cylinder (261-14961-P) takes advantage of modern manufacturing processes to provide a machined, revamped, aluminum master cylinder which looks great under the hood while taking up less space. Aside from weighing less, these Wilwood master cylinders are more compact and higher quality than OE cast iron master cylinders, making them ideal for restomod, pro touring, or show use. They’ll look great under the hood of any driver or project, and with a combination proportioning valve to modulate brake distribution, this package improves braking performance as well.

Features and Benefits:
- Fit Most Domestic ‘60s - ‘80s Vehicles
- Fluid Outlets on Both Sides of the Bore
- Die Cast Aluminum for Light Weight
- Show Quality Polished Finish
- Adjustable Proportioning Valve

This master cylinder is packaged with Wilwood’s own adjustable proportioning valve and includes left-hand mounting brackets, hardware, pushrod, and pre-bent lines. Designed primarily for manual braking system applications, this Wilwood brake master cylinder features a redesigned body machined out of die-cast aluminum and polished for superior quality. It fits most ‘60s to ‘80s vehicles and only weighs three pounds, or 75% less than a cast iron brake master cylinder. OE style master cylinders are around one inch longer and one to two inches taller than the Wilwood unit, making the Wilwood compact master cylinder ideal if space under the hood is an issue. If you want a slim and great looking master cylinder for your driver or project, the Wilwood (261-14961-P) compact master cylinder is the premium option.
