I color-coded my ABS unit and brake lines, but I rubbed the paint off the four other lines as I was installing the rear line. Does anybody know where to find out which line goes where?

blksilverado asked in 2008 and got no replies.

There are five ports on the ABS unit, and the only one I am sure of is the rear brake line, which goes in the top driver's side port.
The GM service manual does not have this info.

 

Same truck in your Sig???

 

Yes. 2000 2WD 2500

 

I have a 1500 so I will go look. If you need a 2500 not sure when I can go look at the one my buddy owns.

 

Seriously? Thanks!

 

The 2 bottom ones near the ground are feeding the Brake booster. The one close to the frame rail is feeding the front and the one further away is feeding the rear.

The 3 top lines are feeding the calipers. the one closest to the frame is feeding the rear brakes the middle one is feeding the right front and the furthest away from the frame is feeding the left front caliper. Seem's to be the same on my 05 as well.

HTH

 

You are wonderful. If you ever need help, PM me so I get notified right away. Thanks!

 

Always here to help when I can!!! That's what this site is all about.

 

And of course when you say left front, that is the driver's side. Right?

 

I did have two switched, they line up much better FastrBrick's way.
