This particular truck is a spare , rarely used unit.
Once I can get my hands on it , I guess I will open the valve up and see if its repairable / new O rings will fix it . As Ive looked for days and found nothing as far as a new replacement or rebuild kit

What type material is brake fluid safe if I decided to get O rings ?
