I posted a while ago about a Jeep that I'd been working on after it having sat for many, many years. It's a 2004 wrangler 4.0. Thanks to a previous post I made earlier this year and a bunch of info I found just searching the forums, she's alive and running well!
But, there's still one issue left to fix. When I finally got everything else good to go, I got in and pushed down on the brake pedal. Went straight to the floor, didn't matter if it was off or on. So I picked up some brake fluid and completely flushed the brakes. Brake pedal was much, much better. Feels like there could still be some air in the lines, but the brakes work and it doesn't go to the floor.
Now, if it's on, the pedal goes down a good bit before the brakes kick in. I can hear sort of a quiet "whoosh" sound when pressing down on the pedal (If I'm not imagining things). I let the Jeep idle for about a minute or so, pressed down on the pedal and turned off the Jeep. The pedal started slowly coming back up after just a few seconds, almost immediately. I tested the check valve (Blew into it/sucked air from it) and it seems to be working.
Any thoughts? I'm assuming the brake booster is toast, but, if someone else with more experience has any input it'd be greatly appreciated before I put the order in for a new booster. Could it be the O ring between the booster and master? Or more likely to be the booster? Thanks!
(I'll be posting before/afters of the Jeep once I finish fixing up everything and fixing the paint job)
