brake issue

[mikekaz1]

sometimes after stopping hard/quick my truck loses all brake pressure and it takes ~30 seconds of driving/ pumping to build it back up to a normal pedal. I don't notice any leaks anywhere...    I'm assuming its a booster issue but curious on others inputs

Money is on brake booster. Re Bleed the brakes using the write up in the do it yourself section. If that doesn't improve it I'd upgrade to a WJ/95-96XJ booster. Think the ZJ's were the same also but not 100%

I have a98  zj booster in my basement... just haven't done it yet

I did the MC and booster at the same time. Orielly's has pre 'bubble' flared brake line. I got a 3 foot stick of that and cut it in half, double flared the other side, added the correct fittings and bent it as I went along. So far no leaks and it was my first time :D just make sure you bleed like that link says.

They're actually building an oriellys just down the street from me. I'm pumped!
