Our 1 Ton brake master to booster adapter is a must when swapping larger one ton axles and brakes under your your 05-15 Tacoma. The brakes are always a tough thing to get right when you are putting much larger calipers under a truck that was never intended to use something that big.
If you don't use the proper pairing of mater cylinder and booster you will experience a musshy peddle and very litte if any braking power. 
If you run the right master but without the correct booster, you will have an exteremly stiff peddle but no power to push the adaquite amount of fluid to stop.
We have found the perfect match of both master cylinder and brake booster!
You will use our brake master to booster adapter to run a 2001 Dodge 2500 master cylinder with a brake booster from a 09+ Toyota Tundra with the 5.7L engine.
The master is a 1.25" bore and the booster is a large dual diapham. 
With this match you will be able to keep your fuse box in the stock location.
Use our laser cut 3/8s adapter plate to mount the Dodge master cylinder to the Tundra booster along with our aluminum pushrod adapter for the perfect fit.
 
Install notes:
Make sure to seal between the booster and adapter with RTV or silcone to ensure no vacuum leaks. The master will use the factory o-ring to seal.
