Wilwood 260-4893 Master Cylinder Adapter

If you're looking for a great upgrade to add some stopping power to either your Toyota axles or One Ton setup with smaller Chevy calipers, we have made an adapter to solve your problems!

Made from Billet Aluminum

This adapter is designed to adapt a Wilwood 260-4893 Master Cylinder to your 4 bolt Toyota booster's. 79-95 Hilux pickup and 4 runner as well as some Tacoma with the 4 bolt booster.

We chose to offer this adapter in conjunction with our other GM 1-Ton adapter because of the great qualities the Wilwood Master brings to the table.

  • Lighter and smaller in overall size
  • Less prone to leaking
  • Cost effective

We have been running this master cylinder in our race truck #4521 without any issues!


  • Pushrod adjustment will need to be made to get the correct pedal travel for safe and effective braking.
  • The Wilwood Master uses a metric stud size to mount on the firewall.  We used larger 3/8" bolts. IT WILL NEED TO BE SLIGHTLY DRILLED OUT.
  • This master cylinder comes with fittings to re-flare your existing lines. Our GM master adapter line fittings WILL NOT work with this master cylinder.
