Now that all the hard parts ore off getting powder coated, it's time to dot some i's and cross some t's.
I'm sure most of you Toyota die hards have heard of the FJ80 brake master cylinder swap. It's a popular swap but I doubt most people realize why. Bigger is not always better and simply bolting on a larger bore master is not going to make your brakes better. In some cases, it will make your brakes worse. In my experience, I have found that using the larger master in conjunction with the larger booster is the trick. But then that leads us back to the booster. Who sells a "FJ80 brake master cylinder"? Go down to your local auto parts store and ask for one. About six varieties come up. Do you have rear disc brakes? ABS? What year is the truck? All good questions. Places like Marlin Crawler and Trail Gear sell the mythical master cylinder, but I like to go to the source.
One question that needs to be answered before you buy a new brake master is disc/disc or disc/drum? If you've got disc front brakes and drum rear brakes, then you need the early FJ80 master.
Specter Off Road sells them at a reasonable price, and by application too.
Here's a pic of the new master with the box and it's part number. I hope this saves some of you from a potential headache.
