What is this thing? [SOLVED - Load Sensing Proportioning Valve]

[quatin]

reviving an older thread. I have a 1999 Toyota 4runner 2wd base model with the Rear Brake Proportioning Valve . my 4runner is lifted 2.5 inches and ive read that lifting a base model will cose the brake light to turn on and off. is there a way to fix this besides from pulling the light fuse? just kinda of annoying to see the light pop on and off lol.

also anyone tried the Revtek Rear Brake Proportioning Valve Relocate Kit for 1996-2004 Toyota Tacoma to fix this problem?

I believe you add an extension arm to the existing lever arm. You probably have to make it yourself and play with the length until the lever is fully down unloaded.

Can you Provide Detail on on how you revived Old Valve? I think i am in the same boat you were in. Can this be done while attached to the vehicle?
