Yes, Left is always the Drivers side when referring to a vehicle.

Don't forget to bleed the brakes manually But also use the automated Bleed procedure with a scan tool.

Glad you got it in!!!

They fit great, except I think they are for 4WD. I was able to stretch them around the upper A-frame pivots, so all is well.

When repairing my 05 I found out the 4x4 have different front brake lines. The I don't think the one that runs over to the right side would fit on a non 4x4 frame.

On My 00 2wd it drops down next to the front a frame mount. On my 05 4x4 it comes down just in front of the shock mount. Just from what I have in my drive way

I wonder if the difference is 1500 vs 2500. The upper A frame mounts are different on a 2500 from a 1500 from what I Remember.

I'd feel better if I could get someone else to confirm the listing above. Only reason is because it is different than shown here (for an '03 1500):

I assume what is posted on this site is correct, and 99.9% sure that the rear port on the M/C is the front brake system, which would mean the mechanic who replaced my brake lines (and rear pads) swapped the inputs from the master cylinder into the ABS unit. This would seem to be a plausible explanation for why rear brakes are hot as a MF and the front are not (and the truck isn't stopping the greatest) when i didn't have a problem before. I already replaced one rear caliper that was sticking a bit thinking that was the problem and backed off both ebrake shoes to be sure they weren't dragging. Guess this should have donned on me earlier to check...

Also my truck (2002 GMC 2500HD, 4x4 with 8.1L) does not have a proportioning valve which I think is OEM right?

Thanks, Jeff

What I stated was correct for the 1500. I do not have a 2500 to confirm but the OP said it worked that way on his truck as well.

Not all trucks have an external proportioning valve under the master cylinder.
