Master Cylinders

The “feel” of a brake pedal is something most drivers have a difficult time articulating. Builders can spend dozens of man hours perfecting the performance of their car’s brakes, all while ensuring that they “feel right” for the driver.

The vehicle’s master cylinder is going to be responsible not only for brake performance but for the way they “feel” to the driver. Of course, your competition is going to determine which master cylinder is appropriate for your application also.

Day Motor Sports offers a variety of master cylinders. We carry each model in a variety of bore sizes to ensure that your braking performance and pedal feel is exactly how you want it.

Master Cylinder Options

Bore Size

Bore size is fundamental to creating the pedal feel and brake performance your build needs. A larger bore will provide more fluid to the brakes while a smaller bore will provide less. Getting the right mixture is fundamental to ensuring brake performance.


Your car’s braking system needs will determine which reservoir you select for your master cylinder. Some of our offerings come with multiple reservoirs to help ensure you have one big enough for your needs.

Single Or Tandem

For smaller cars, like sprint, micro sprint, and midget cars, you won’t need a tandem master cylinder. For drag racing and larger vehicles, a tandem master cylinder will independently power your front and rear disc brakes.
