I am looking at putting in rear disk brakes on my 69 FJ40 to go with the 76 disc front axle that I have under it now. I also have a 76 booster and master setup. I have been reading different posts and parts sites and found a master cylinder offered by JT Outfitters that is aisin made and looks totaly different from the stock master. Has anyone used this master set and if so what are the pros and cons of this one compared to the stock one. Thanks for any help you can give on the subject.. :usa: :usa:
