Soo what is this pump? I think it's a pump. I only say that because when my jeep is off but the ignition is on and I hit the brakes it makes a humming noise like it's pumping. I traced the hose back and I believe it goes to the vacuum booster for the brakes. I'm just wondering if that is true.. thanks!

 

Sorry if the pictures are sideways.. blame the app not me hah

 

Anti-lock brakes?

 

No the ABS motor thing would be way more visible. I wanna say it's a Bendix9 system with the electric brake booster.

 

Yep, i looked it up. the booster pump would be on the passenger side of the Jeep.

I believe I do have abs

 

Okay cool. So when I upgrade the brake booster eventually would I still use the electric pump?

 

I wouldn't, but IDK if you can replace it with a normal system.

 

Yeah I'll look into it. Alright thanks guys!
