For the eariler Jeeps, you can upgrade the brakes very easily.

"Did U know that the brakes on early CJs can be upgraded to 11x2" drum brakes. To do this upgrade it is nessessary to get used or new backing plates from a early to mid-70's CJ that has the 11x2" assembly. Once the backing plates have been located/purchased, the rest of the parts are available by purchasing the parts for a 11x2" drum brake assy."

Yup, and very easy to add disc Brakes. Main kicker is the MC queston. Some people are lucky and can use the original Mc but others have to play the game and find the MC that works best :(

Dan,
Does the MC problem come in when you add disk brakes :question: If you stay with just the drum brake would you have this problem.

Reason I ask I know someone was considering doing this and was coming up empty and Rollbar has propably come up with a solution on this Trick. :question:

I swapped the 11 brakes originally the same time as the MC swap, but if just swapping in the larger drum brakes the original MC works out very well actually, and shouldnt be a problem. i think a main thing for safety sake is the original MC is a single resovoir, so when you have a leak, you lose allll of the fluid and end up with no brakes :( A hot swap to keep the original look is to get a 70-71 cj5 MC that is dual resovior, but it needs a brackets. On the other forum www.earlycj5.com there has been plenty of writeups to do the conversion, and actually a buddy of mine posted over there a picture of when he built a CJ3A and used a later CJ MC but under the floor. he pretty much made a bracket out of a piece of angle iron and bolted the MC to that angle iron, and the angle iron was welded or botled to the frame side ( idont remember) but it looekd really clean, kept the stock appearance, but allowed more safety.

Dan,

Thanks for the additional info. It's amazing how the MC were underneath the cab in the old days. I'm dealing with this now. :question:

The overlooked problem with the disc conversion, is the volume of fluid moved in a single pedal stroke. Calipers require more fluid transfer to make the larger piston actuate, while the pistons in a drum aplication are fairly consistent from veh. to veh.
