I will be installing on stock brake proportioning valve on my 1980 Chevy Monte Carlo is there any special things I need to do or do I just on bolt the lines and the valve and replace the new proportioning valve, remove and install the lines or do I need to set anything on the new proportioning valve ? Thanks

Shouldn't other than bleeding the system out. There is a pin on the prop valve that can be depressed while bleeding. I've only needed to do that once when I couldn't get the system to bleed out all the way.

It's kinda like a reset button but needs to stay depressed while bleeding. There is a tool but I used a heavy duty zip tie I had handy at the time.

That doesn't need to be done unless it's unable to bleed.

The wheel farthest away from the master cylinder is bled first which in most cases is in this order: Right Rear, Left Rear, Right Front, Left Front. Failure to bleed in the proper order will cause air to remain in the lines. This is because if you bleed a short line, (ex. front lines) before bleeding a long line (ex. rear lines), the fluid in the short line will compress and prevent enough pressure from being built up in the long line to expel the air. Furthermore, incorrect bleeding order will cause pressure to build up on one side of the proportioning valve, causing it to close on the low pressure side making it impossible to force fluid to the rear lines. If this happens you will never be able to bleed the system until you readjust the proportioning Valve.
