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.

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!)
