Brake Shoes won't Move a bit
Hey everyone, first off Im super stoked to finally be posting here. Ive used this blog for the past couple weeks to get our 1991 International 3800 Bus road worthy.
Air system achieves 120 psi, with no leaks...
when parking brake released, air releases from can, push rod moves, slack adjuster cam moves....no release
I have tried shifting to drive and reverse....nothing
I chocked tires put bus in Neutral released park brake and beat on drums...nothing
One source told be to spray pb blaster on brake shoes....I dont think this is a good idea...??? I thought lubrication on pads and drum was a BIG no no, however for this case maybe its necessary
going to try pumping brakes hard...9 to 10 times...haven't tried that
Does anyone have any experience getting someone (tow-truck) to pull on the bus to get the rear wheels to break free? Any advice on this method would be great. I want to fully understand if this is possible and words of caution and or standard procedure prior to hiring a tow truck to yard on this beast.
I was thinking about caging the brakes...this insures that the brakes are in the release position right??? would this help at any point in my endavours?
HALP PLEASE...AND THANK YOU
