Default 1990 XJ Brake Part Question!?!?!

Hey guys and gals,

While working on my sisters 90 XJ, she had told me about her brakes making a weird noise. So after investigating, I found when you hit the brake pedal, there is a loud, clicking/ almost compressor like noise from some kind of component under the coolant resivoir on the passenger side of the rig. There is something with high pressure brake lines running to it from the master cylinde. Does anyone have any idea what this is?? I will take pics of it tomorrow. Any and all help will be much appreciated.

The sound is normal,it is your high pressure pump for your abs,if you follow the lines from it they go over to the master cylinder,under the back seat on the drivers side is the controller for the abs system,looks like an amp,black box. abs brakes work great,if it ever goes out it is very exspensive to replace,I just swapped mine over to normal power brakes.
