Ianbeaulieu Okay thank y'all, I talked to my buddy and he said master cylinder also haha, so I will be replacing that

kik What you're describing is usually a bad master cylinder. My booster is 24 yrs. old and still fine. I'm on the third master cylinder.

AllMudd With the leak by the master cylinder you probably won't be able to bleed it properly depending on how bad the leak is. But when you replace any brake line, caliper, brake cylinder etc. you have to bleed the whole system sorry.

I will try to completely bleed the system tomorrow, I would take it to my buddy's but the only way to take it would be to drive it

But sounds like you have air. Start at right rear, then left rear, right front and finally left front. Bleed the brakes like this until no are comes out. Then try again. If you still have spongy brakes then you have a leak some where. I would start at the MC myself but again bleeding correctly and thoroughly is most important!
Their soft before i start the jeep, and when I replaced my hard line I only took fluid out of the front brakes, I did not mess with the rear brakes, should i still bleed them?

I was thinking the brake power booster, how hard is that to replace?

Drop the brake peddle connection and the booster is bolted to the firewall. You can separate the master no problem.
Morris 4x4 sells them, or am I wrong? Lol
