Brake booster '00 wj

Hey, i have the hissing brake booster problem at 186k miles. Tracked it down to the boot on the push rod inside the car. Wanting to know 2 things, 1 is there a way to replace just that boot? 2 if i'm gonna replace, should i spend the extra on a new one, or get the $50 junkyard version. Just worried i'm gonna spend the grueling amount of time it takes to replace it, just to get the same hissing, poor performance out of the junkyard jeep part. Thanks.

Re: Brake booster '00 wj

Never had to deal with the booster yet, but according to the manual is the boot a replaceable part. But i donīt think that the boot itself is the problem: at the front face of the boot, where the brake rod enters, sits a filter, which filters atmospheric air, which enters the booster during braking. Inside the booster there are two diaphragms, which should separate the vacuum from the atmospheric air. When you have a hissing at the boot filter, then it means that a diaphragm inside is leaking, which i believe is non replaceable.
If you can find a booster from a low milage jeep, i should say, why not.
How much is it new?

Re: Brake booster '00 wj

Just checked on Rockauto.com and a new Mopar booster costs $ 200. A remanufactured from Cardone will be around $ 85 and another $65 for the core.
For the $35 difference with a junkyard part, i would go with the remanufactured one.
The replacement of the part doesnīt seem to be that bad, the procedure is hereby attached.

Re: Brake booster '00 wj

Right on. I haven't checked autozone, because i have advance auto and o'reilly closer to me. They each want $129-$140 for a re-man, $160 for new. Found a salvage yard with 3 to choose from for $45 a piece. I appreciate the manual sheet. Watched a couple videos on it, and it doesn't look too bad. I guess it's gonna depend on the miles on the ones at the salvage place, and what kind of money i have. I'll post as it goes.

Re: Brake booster '00 wj

Had to take it to a shop to replace, because i didn't have access to a scan tool for bleeding the ABS system. Good thing, too, because the first one (re-man from advance) was faulty. It would suck the pedal to the floor before you even cranked it up. No hissing, now, and stops on a dime. All in all, it only cost about $$270, so not bad.
