I have a Cat 257B and the Parking Brake Won't Release. Any tips or suggestions?
The door switch only stops the implements from working. nothing to do with the park brake/drive system.I bypassed both the seat switch and the lap bar switch to no avail. It is not an enclosed cab, so there is no door switch.
If the machine tries to move then I don't think the problem is with the electrical side of the parking brake. Does the park brake light go off when you press the switch.?The machine starts, all hydraulics work, and if you push the parking brake switch and push on the lever, the machine tries to move, but will not release the parking brake.
In that case an electrical problem with the park brake is unlikely IMHO.The parking brake light does go out when you activate the switch.
