Thanks to this forum for existing.
Apparently, it is impossible to find schematics for specific automobiles online. Kinda shocking, considering that I easily found the schematics to my 1970 BSA motorcycle in under 5 minutes of web searching. But a 2003 Buick Century? I'm hour 5 into my web search, and have decided to roll one up, create an account and post here in desperation.
So, I am redoing the brake lines on my 2003 3.1L V6 non-ABS equipped
I need to know where the proportioning valves are supposed to be. Are there two inline with the rear brake lines, near the gas tank? Is there supposed to be a proportioning valve distributor mounted to the firewall? Is there supposed to be a proportioning valve built-in to the master cylinder?
So far (due to the rainy weather here), I've only managed to cut out one brake line (passenger, rear), and I've identified what appears to be 3 separate fittings along the line. I'm pretty sure that they are:
-a compression fitting splice (illegal!)
-a bubble flare fitting splice (that'* better)
-a mystery fitting that kinda looks like it might be some sort of bubble flare splice, though it is about half the length of the aforementioned bubble flare splice. (could this possibly be a proportioning valve!?)
Any help would be greatly appreciated.
