Just acquired a 1976 FJ40. There is an unknown lever under the steering column. Has wires connected to the back and a tube running through the firewall to the master cylinder (see images). PO had no clue what is was for....anyone?
Not on a 40 series... there are no better E-Brakes.
Sorry, I'll have to fix that... No E-Brake is better.
I think I remember a few days when my E-brake held well. But in all seriousness, there are limitations to a driveshaft E-Brake on an open Diff on rough terrain. Often a line lock can be useful to increase staying power while winching someone else.
When I bought my 68 many year ago the rear hydraulic broke line had a Tee with a line that went to a hose with a plug. This plug would hook to a trailer the original owner had. I never used it and removed the Tee years ago. This was on the stock non booster single circuit brake line, scary to say the least. The handle reminds of a brake controller that can apply brakes to just the trailer to straighten out a trailer that is fishtailing.
Looks like an old school trailer brake controller to me - pressing the foot brake activates it automatically, or you can use the lever to correct trailer wag by actuating the trailer brakes independently.
Old school trailer brake. When you applied the brakes, the trailer would also have brakes applied. When you were desending down a steep grade and didn't want to ride the brakes, but wanted the trailer brakes to hold you back from picking up too much speed you could operate the manual lever protruding out the front of the box to operate trailer brakes only- - -easy deal.
