Brake line routing ?
Anyone have any idea why the rear brake lines on my 70 c10 has the rear brake lines routed on the right side. They start on the left (master cylinder) then cross over to the right side (under the motor) then go down the right side to the rear and back to the center. It would have used less material, less bends and I just think easier. Did GM have a reason they did it the long way. Just curious.

Re: Brake line routing ?
Yes two wheel and 4 wheel drives are done that way
I figure it was there way of helping balance front and rear brakes in conjunction with the proportioning valve on with drum brakes and carried that setup through into disc brake setups |

Re: Brake line routing ?
With all of the lines, both brake and fuel going down the same side of the truck, it was probably easyer AKA cheaper, to assemble the truck. Two men, one in the front, one in the rear put the line bundle on the frame and tighten down the screws.

Re: Brake line routing ?
ALL of these trucks came that way from the factory.

When I did the frame off on my 68 C10 LS swap I ran both fuel and brake lines down the drivers side. I built my brake lines. Used Ni-Copp lines.

Re: Brake line routing ?
Brakes & fuel both run down the passenger side on these trucks.

Re: Brake line routing ?
The reason is fire safety, there is a code that requires electrical and flammable be routed x number of inches apart. The electrical that must be located in proximity to flammables must meet a code and\or use a resistance sending unit designed for use in flammables. All that safety and put the tank in the cab right? The big three only did what they had to do via the codes written by suits that never had a busted knuckle...Most were good, some didn't make any sense...Here's one that stifled engineers I confronted in the auto plants for 40+ years..."Whats the difference between pipe and tube?"
