M35A3 locked up

[summittman]

I have a 93 M353c that was running fine . A large oak tree fell across the hood during ice storm. Hood was crushed and passener wind sheild. Radiator leaking and T charger damaged. The only air line cut was to fan. I pluged and air builds up fine when engine ,running but truck will not move now. Its locked down. Any ideas out there?

Did you release the parking brake?

Not sure what your trying to say , but with or without air in the system , the brakes should not be locked up . They are not your standard air brakes . You could open a bleeder on a brake cylinder to see if they are under pressure .

Sounds like the brakes are locked up.

With a "clout" like that all sorts of "hidden" damage could be prevelent.
Looking at the scematic for the brakes (tried to post it for you but every attemp results in logging out)
And you could try A) Bleed off all the air. B) crack one front O/S Bleed Nut and one Rear N/S bleed nut. (you will observe if the system is pressurised unduly.) and the brakes will ease if this is the case, Also try Cracking the Master cyl and air pack to observe the results. Before all this CHOCK your Wheels.
Post your findings and results please.
