front brake line setup help
 

im tryin to figure out how the two lines coming from the master cylinder connect to the rest of the front brake lines. i saw in the lmc catalog their connected by a TEE fitting but theres two lines from the MC, one from the rear brakes, one from drivers side and one from passenger side. i dont see how a tee would help

Don't the lines run to each front brake hose (the two front brake lines off the master cylinder), the rear line runs back to a hose to the tee fitting @ the rear axle, with lines running to each rear brake. If there's a trailer brake setup plumbed into the brake line @ the master cylinder, that would be the only tee fitting under the hood. Put up a photo, and remove all speculation.

Depends on the yr of your truck. For the most part the rear brakes were plumb to the rear axel with one line then into a tee for ea wheel.

The fronts line on earlier trucks ( Don't know the yr it changed ) had separate lines for ea wheel right from the proportioning valve or MC to ea wheel.
I know in 72 it was one line down to a tee inside the frame rail, then to ea wheel.

If yours was originaly 2 separate lines then keep it the same.

i think i.got it figured out. i was thinking they all connected together but one line from the mc goes to the back . the two front join with a tee before going up to the mc. i will post pics when i.get to the shop

Two bits of advice for you.

1.Buy a copy of the factory assembly manual for 67-72 trucks. It will save you a great deal of time and money.
2. never, ever buy anything from LMC

Here's the routing diagram from the factory manual for your front brake lines.

Yep... what Fitz said. Some lines go inside the frame and some run outside the frame depending on year and application.
