I have a 89 SC that just developed a brake fluid leak.I traced the leak to this thing that looks like a metal box about 4 inches in length and is located on the drivers side way down in the engine bay.Almost looks like it is sitting on the frame.It has some skinny metal brake lines running in and out of it.I know this description is vague but do any of you guys know what this thing is called or have a part #??Im sick of adding brake fluid every day..Thanks...
