I took my 60 cj5 to the shop because of “ all but no” brakes. They tried 2 sets of brake cylinders, neither fit. I ordered a set from Amazon that they said would fit... They didn’t. Apparently these are not factory brakes. My next step is to take the old set to a FLAPS and hope they can match them. I don’t have high expectations. Any ideas? I know there are fronts and rears.
