you are going to have to upgrade your proportioning valve and possibly your master cylinder. The pistons are much larger on disc brakes and require more volume of fluid. Bleeding it more might get some of the bubbles out, but it will still suck.

dont know if any of that would bolt up.

Also, forgive my ignorance as I don't really know too too much about brakes, but it shouldnt matter how much volume the calipers need because once they are bled, they are full of fluid, and the pedal should be firm. Once all the air is out and everything is full of fluid, as soon as I touch the pedal it should be under pressure.

my master cylinder may not be able to push as much in one stroke or whatever, but that shouldnt change the fact that everything should be firm because the system is full of fluid.

Does that make sense?

Most masters are the same mounting pattern you just have to make sure the stroke is the same. It should be the same but will move more fluid to the front side.

other issue is that the lines come out the opposite side on the newer master cylinders. I'd need new brake lines down to the proportioning valve (i dont even think mine is a proportioning valve, I think its just more of a block that diverts the fluid) and have no idea how to do that.

It is not the amount of pressure it is under that is the problem. It is a problem of volume. On drums the piston is smaller so it doesn't take as much pedal movement for the pads to be in contact with the drum. If it takes double the amount of fluid, it takes double the amount of pedal movement before the pads touch the disk and you start getting pedal pressure.

gotcha.

Well I will ask the FSJ guys if this should work as is, or if I need to convert something else.

I may have to learn how to make brake lines, huh?

It is a nice skill to have for sure. I know I hace no idea as to how to do it myself. But thats the thing about brake lines, I think I only know of one person who knows how to make them.

See now that I really think about it... most of the time that you hear about people just needing to upgrade their proportioning valve is when they upgrade the rear brakes to disc from drum.


I guess what I should really be asking is what do you have on the back? If you have disc front/drum rear you will need a new valve for sure on top of the new master cylinder.


check out this thread that I found googling. It looks like you are not the first guy to go down this road. http://jeepsunlimited.com/forums//sh...d.php?t=487707
