Default Wilwood Brake Master Cylinder Upgrade Kit

Wilwood 1" brake master cylinder upgrade kits now available through Good-Win Racing. The 1" master cylinder pairs perfectly with any big brake kits using the Wilwood calipers.

This is a complete kit and includes everything required for installation. When replacing any brake master cylinder, we always recommend bench bleeding before installation and we have included the tubing and barbed fittings for this.

Kit includes:
  • Wilwood 1" piston master cylinder with twin reservoirs
  • Master to booster adapter bracket
  • Junction fitting and Tee fitting
  • Hand-formable hard lines
  • Nylon barb fittings and clear hose for bench bleeding


Most brake calipers used in big brake kits have smaller piston sizes compared to stock calipers. Although braking performance increases overall, the result of the slight change in piston size gives a "softer" pedal feel and more pedal travel. Depending on the year, your Miata came with either a 7/8" or 15/16" master cylinder. The 1" master cylinder regains the firm and responsive brake pedal the Miata has with the factory calipers.

Note: Fits all years with ABS. Does not fit on the brake booster in 2004-2005 Mazdaspeed. To fit this in a Mazdaspeed Miata you will need to change to a brake booster from a Sport package 2001-2005 Miata.

We've also taken the time to create detailed installation instructions to make the upgrade as smooth as possible. These can be found in our forum HERE.

I've recently installed a 1" master cylinder on in my own car and I have been very impressed by the results. On the road, there was an immediate difference with a much firmer brake pedal and noticeably reduced pedal travel. However, on track is where this upgrade truly shines and the 1" master cylinder greatly improves feel and feedback from the brakes. I found the extra feedback gave me the confidence to consistently push deeper and deeper into braking zones. If you have a big brake kit this kit should be your next purchase, you won't regret it.
