This maybe a dumb question but where is my brake booster? I know what they look like but cant see one where it should be. I have ABS, would that make a diference?

Wheres the vacuum line that goes to it? My buddy has an '01 and he has a half inch vac line running from his intake manifold to his brake booster.
I ask cause Ive read on here that alot of vac leaks on cherokees come the vac line on the brake booster.

You don't have one.

You've got the worst ABS system on the planet....seriously.

My son's 91 Briarwood had the same system and we pipped that POS out. Get down to your local JY and grab a booster, mastercylinder, brakelines and pedal from a 97+ XJ/ZJ and replace the ABS system.

That looks to be an accumulator type deal that I see there, does this have an electric motor to create the brake pressure (such as in a Teves system)?

Hey Frankz will a 2001 brake booster bolt right up into my 92? if not what modifications would i need to preform?

SeriousOffroad

Yes, as long as you grab the aluminum spacer that's behind the booster.
The peddle linkage is what can throw a curveball. Most people snag the brake peddle assy and swap it as well. I did it the hard way by relocating the pin on my 97 when I upgraded my booster. For my son's heep we used a 97 XJ booster and it was a bolt-in upgrade.

sweet. i have the whole 01 sitting. i am in process of swaping alomst everything. doors, front clip, interior(minus dash). I am going 8.8 in a few weeks and needed to upgrade booster for the disk brakes.

You seem to know quite a bit about it, what should i grab the paportioning vavle of of?

SeriousOffroad

Booster, M/C, and Prop valve all from the same rig.
