Been fighting this issue for too long. Parking brake will not release. It started in freezing weather now its constant . Right now it is a lawn ornament. Gonna test pressure at test port on diff lock/parking brake block. What pressures should I encounter there? thanks in advance
550 +/- 50 psi at fast idle with oil at 104*-110*.
Thank you sir. Got all my fittings and short hose. The Diff lock works off the same block. When that is switched on the activation symbol light comes on. Hard to say whether the axles are locking up with out releasing the parting brake to move. This pressure test will help me narrow it down. After the "New England Hurricane" goes through. Will keep you posted on how I make out.
