I'm wanting to install power brakes on my 77 cj7 but I am not sure what all I'd need to buy and change to install it. Would i be able to just buy the brake booster at a parts store and just install that with my stock line an master cylinder or would I have to change all that too? I'm also thinking about swapping my front drums to discs from a jeep of the same year. Would I be able to just go to a parts store and buy calipers and discs and install that? I'm really confused and need help so any little bit would be greatly appreciated!
I also have a 77 CJ, but mine's a 5. So far the best manual to power brake conversion I have seen and will be doing in the next few weeks uses a yj master cylinder and booster in place of the CJ master. Apparantly the best year for a donor is 95 for some upgrade reason. Luckily there is a good one in town for me, the guy wants $100 for the full assembly, but i think I can get $80. The only modding necessary to make it fit is you have either lengthen or shorten the booster input linkage a bit.
Use the search bar at the top of the site, that's how I found out about all this. good luck!
Thanks for the help! At least you were able to get me going in the right direction! But if I go to a parts store and get the booster and master cylinder for a 77 with power brakes would it just bolt up?
There is a bracket between the M/C and the firewall. Your old m/c just bolts right to the firewall. I used a 89 xj booster and m/c but I had to make a braket and a new rod. I dont know anything about the disc brake swap.
