What is the little metal box that the master cylinder goes to called?

Hi All,

Quick question... lost my brakes, brake line to front left wheel rusted through. ok. Made a new line, installed, uh oh I cross-threaded it on one side. What is the metal router(?) below the master cylinder that splits the 2 lines from the master to 4 and directs the brake fluid to the four wheels called?

if I understand your description correctly it is the proportioning valve that splits the brake pressure to front and rear. splits it something like 70/30 more to the front less to rear. not sure if it evens out as you apply more pressure but I gutted mine out when it became an off-road toy more than daily driver.

I believe the whole thing is called the distribution block. The proportioning valve is integrated into the distribution block on most stock applications. I just replaced mine with an adjustable unit for when i have disks in the rear. To replace a stock one i would just go to a junk yard.

Here's the one i used if its of interest http://www.ssbrakes.com/commerce/det....cfm?nPID=8862

Cool. Thanks for the quick reply! I think the junkyard might be the way to go... or Oconee! Can't find it anywhere else.
