Re: Part No for Brake Combination Valve
Quote:
I found out about it during my short tenure as a brake development engineer for truck. I asked if I could borrow it and it somehow never got returned before we all retired. I thought about having the GM Heritage Center scan it and make copies but I still refer to it on almost a daily basis. I have the charts for those 71-72 models but am at the races this weekend. I'll check early next week after I settle back in. (You may have to remind me!) K

Re: Part No for Brake Combination Valve
Thanks Keith, that's interesting and lucky that you have them.
Hoping tomorrow to get at it and try the bleeding tool. Was distracted with other things today. Quote:

Re: Part No for Brake Combination Valve
I am also needing one of these. Those 3 p/ns do not show in any search I have done as remotely available today. Is that the same as Delco 172-1353? There are aftermarket valves available on Ebay and Jegs, but the price varies widely. The interchange appears to be most trucks and big cars like 70s and 80s. Are any of the aftermarket ones any good? Mine (on '83 K20) has the light on, I have pushed and pulled the pin but it does not move. I have a new Delco master cylinder to put on at the same time, but I don't really want to open up the system until I have all the parts to fix it on hand.
