Is this for brake bias? Under what circumstances would you change it? I've never had air brakes before,not even sure they are factory. This truck has been heavily modified in the past. It all works,but is there anything to look out for? Thanks guys.

We used to put it on on wet pavement with a light load.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | |
