kscarbel2 Posted July 20, 2020 Share Posted July 20, 2020 The parking brake control valve is located between the driver’s seat and the passenger bench seat.

Sonny Chapman Posted July 20, 2020 Author Share Posted July 20, 2020 Ok that’s what I was afraid of is it the lever with the lock you have to pull up if so looks like the lines going to it are all gone.Do you know whether they go to the rear end or master cylinder.

It's been years. I can't imagine how the lines to the valve would be all wrong.

mrsmackpaul Posted July 20, 2020 Share Posted July 20, 2020 I would guess they would go to the rear end as it wouldn't work if you had a hydraulic failure and I'm pretty sure they are meant to be fail safe Paul Quote Link to comment https://www.bigmacktrucks.com/topic/63383-parking-brake-on-1986-midliner-air-over-hydraulic/#findComment-456268 Share on other sites More sharing options...
