brake combination valve

[ktedesco]

Hello everyone. I am new to the board and have found it EXTREMELY helpful. I purchased a 90 K5 a week ago with the intent to build it up. I just installed a 4 in. lift and of course had to disconnect the brake lines. After completing the lift, I bled the brakes and and the dash light is still on, assume I still have air in the lines. I looked into it and Chiltons manual says to open the combination valve. Problem is, I can't find it. Sounds like I am stupid but manual shows it on front left frame near the steering gear. All I have there are the 2 lines coming from proportioning valve and spliting to the LF, RF and rear wheels. Do some models not have the combination valve? Any help is greatly appreciated! Thanks

Proportioning and combination valve are one and the same (actually thats why its called a combo valve and not proportioning) on these trucks.

Thanks for the help. I bled the brakes more without doing anything to the combination valve and I seem to have a firm pedal and good braking now. The dash light is no longer on so it should be ok.
