Hi all...this is attached to the proportioning valve and to the booster. Have no idea what it is, and have never had a Z with it before (or ignored its presence)

Any help?

I'll guess, Hydraulic pressure actuated Brake light switch.

Cause putting that in was easier than replacing the 2$ switch at the brake pedal....

Could be..it is grounded on the firewall and has a fused link that ended in the cowl bay. Horrible things, btw, cowl bays. I had "fun" for about 15 minutes this morning with an air compressor and a cowl bay, and two towels.

Could be an electrically controlled valve for locking the front brakes after being pressured by a foot press.... great for burning rubber.

I just realized it has a line in AND out. Might be a line lock to the front brakes. Foot on brake, turn it on, valve closes, pressure stays trapped in front, do burn out, carry on.

and what you do with a towel in the cowl area should stay between you and the car... Surprised it took you 15 minutes....

and philip beats me to it. But my joke part was better...

Did anyone consider the use of the line-lock as an anti-theft device?........Hard to move a car w/ locked wheels!
