1979 CJ 5 Power brakes

CJ came with power brakes from factory

all symptoms lead me to believe booster went out (hard brake pedal with engine running or not)

17 lbs vaccum at booster and valve working

searching local auto parts stores, they only have master cylinder and booster from an 82 and 83. It looks the same. Will it work?

searching on line I can find a booster for 76-83 for twice the price as the complete set up for the 82 amd 83?

Hey Dumb Asterisk Asterisk Asterisk Asterisk,

It will work, probably. The 82 to 85 had a slightly different set up with different front calipers and proportioning valve and mounting brackets and the MC/Booster is different from pre 82 to 82 to 86.

I have had different master cylinder / booster arrangements over the years including from a Toyota Kijang and mostly they will bolt up with a little work and then I find the actuating rod is no longer the correct length to match the brackets and pedals and have to cut and weld the rod. OK, so at one time I was sufferring from front lock up but that was cured by going to a 1981 CJ setup.

HOWEVER if you are going to go non standard you may as well go the whole hog and put on the double diaphragm YJ booster and Mastercylinder, look up threads on here about brake upgrades.
