braking system leak


Asked by Nov 09, 2015 at 08:55 PM about the 1999 Chevrolet Suburban C1500 LS

Question type: Maintenance & Repair

I have a leak coming from my braking system, but I'm actually not sure where it is coming from.  

Here is a picture of it:

Can anyone help me with which part this nipple is connected to and why it would be leaking.

Looks like the pump and modulator assembly for the anti-lock brake system (ABS). HTH. -Jim

If that is a nipple then it is a bleeder screw. Tighten it up and the leak will stop if that is what it is. Can't tell from the photo though.
