I have a 1967 Mustang with drums all around....I purchased a disc brake kit from Chokostang company. Big mistake...installed all the parts and never got the brakes to function like they should. Went thru entire system new lines rebuilt the rear drums all new parts...brakes would not work. Frustrated finally had to bite the bullet and take car to local restorer and he said master/booster were not matched for the particular setup. Also the front calipers were leaking-these were all new part of the kit. They never saw the road, so why is it they leaked? Junk!! Brakes would never work. After being upset that I got ripped off buyer beware....happy now the car is driveable. Original kit cost $900 repairing so called correct kit another $900 + labor. Live and learn.
