So I'm thinking of adding a brake booster to my 1972 cj5. I've asked a few friends and have done some research but I need a few questions answered from some real CJ experts. Right now, there is no booster at all on my set up. I have seen both used and new boosters for early 1980s model CJ7s. I want to make sure this will work with my CJ5. On my CJ5, the master cylinder rod is connected to the top of the brake pedal -- above the pivot. This means, when I apply the brake, the master cylinder rod pulls toward the firewall. I know that on Cherokees when the brake is applied the master cyliner rod pushes toward the front bumper. If I buy a booster for, say, a 1981 CJ7, will the rod pull or push? Other than that, I know I need to worry about the length of the rod (to prevent the brake lights from staying on even when the pedal is not engaged) and I need to worry about the size of the booster interfearing with the air filter. Does anyone know of anythign else I need to watch out for? If I can't use a booster from an early CJ7, what can I use. Also, I've heard YJ boosters are much superior to CJs. Again, I have he same question. Do they push or pull? Earl

If there's a brake booster, it's a big cylindrical looking thing, between the master cylinder and the firewall. Accessible form the engine compartment.
