Looking for a diagram showing the complete proper brake line routing for a 49' 3800 Panel.
The previous mechanic had stripped the entire system, so I have no reference.
Everything else has been replaced to original specs. Just need the diagram.
Thanks!

| | | | | Joined: Oct 2015 Posts: 27 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2015 Posts: 27 | It appears that one brake line only (Unlike my 55.1, No T block at the back of the master cylinder) comes from the master cylinder, then crosses the rear crossmember to a T which goes forward to another T, I assume to cross the front crossmember to get to the LF Wheel.
Can anyone confirm this?
Thanks!

From tee one hard line in each direction to each wheel cylinder. Frontward from tee. Hard line to tee by right front wheel. Short hardline to bracket. Rubber line from bracket to wheel cylinder. Other end of tee. Hardline over to left front bracket. Rubber line from bracket to cylinder. Hope it helps. Fitting brackets should already be on frame.
