1990 4Runner brake line routing / diagram (1 Viewer)

[ozarkmud]

Hi everyone,

I have a pickup FSM and a 80 series FSM, and neither seem to show how the brake lines are run.

I want to make my 4Runner have brakes only on the front until I can get the burst rear line replaced. There's two lines off the master cylinder and looking at it, I thought the one closer to the front of the vehicle was the front brakes. I plugged the rear part on the master cylinder with a Absolute Witt's End plug, but it doesn't seem right. Is it a diagonal setup, where one port on the master cylinder does one diagonal?

Thanks!

you cant really do that because of the LSPV plumbing. you need to take the rf line out of the "T" and route it directly to the rf brake hose.
then the plug in the mc will work.

however, you should fix it right and not be driving on half azzed brakes.

Thank you! That makes sense about the LSPV.

I'm driving other vehicles, but it would give me the option to drive it to a place to replace the line. I got the stuff to do it myself, but I've never done it and am debating if I should spare the time. I'm not sure how long it would take.

I found this thread with pictures that clear it up for me: How-To: LSPV delete - YotaTech Forums - https://www.yotatech.com/forums/f116/how-lspv-delete-233633/

Plug the 2 lines off the passenger side frame rail going to the rear.
