Tried doing a quick search, yielded no definite answers.

Im swapping in a HP D44 from a 77 F150 into my TJ...chevy knuckles, ford brakes. What will I need to do to get my TJ brake lines to fit? Will I need to ream out the banjo bolt to fit or will it simply fit on as is?

I havent looked to far into it, just hoping to get everything prepared before the teardown next week.

TIA

I believe that I had to drill out the banjo hole in my yj brake lines to work with the ford brakes and ford banjo bolt. Easy task though.

For the 79 ford 1 ton disc brakes (dual pistons), the YJ/TJ brake line will bolt right up.
For the Chevy 3/4 ton disc brakes (single pistons), I used stock TJ front brake lines, but I had to drill them to 7/16" and buy 7/16" banjo bolts.

I bought new lines. You can get RE extended CJ lines which use a 7/16 banjo bolt. If you need longer lines, Superlift makes a 30" brakeline with 7/16 that they sell with their mid-70s Chevy lift kits. This is assuming you used Chevy brakes. Ford stuff I know nothing about.

I used Chevy brakes in the rear and ford in the front. I didn't need anything longer than stock TJ front lines in the rear.

i did a similar swap, started with a 78 f-250 hp44, swapped to 5on5.5. used FSJ flat top knuckles, backing plates, small bearing spindles and 79ford f-150 hub and rotor. now for the calipers i had earlier model FSJ/CHEVY calipers that came off a 76. they had a 7/16 banjo. i searched a little and found that the later model (ie 85 FSJ/CHEVY) calipers had a 3/8. i used the older ones for cores and bought loaded 85 FSJ/CHEVY calipers for approx 70 bucks(best set they sold, had some for approx 35 also) from napa, they bolted right up to my TJ brake lines.

Sorry for not replying to your email sooner Kurt. :(

TJ brake lines will bolt up fine w/ '80-ish Jeep/Chev calipers. No reaming needed, just buy the proper banjo bolts (10mm IIRC).

Wish I would have know that when I did my same exact swap. The only difference was I kept the older (mid 70s calipers). I would rather have had something that bolted up. Oh well, when its time to replace them, I will know what to get.
