Subject: RE: Case W11 brakes



I feel your pain.

On the W14 a company I worked for we had the same problem. I wound up removing the entire hub assemblies to get the brakes apart. The drums had seized to the hubs. Also the shoes would NOT retract when the bolts in back were released. I assume you know they are work a cam that sets the shoe spacing.

It's in the parts book if you don't already know what I am talking about.

I would guess your brakes are extended and will not retract and the cam can now just spin freely, the shoe is all the way extended.

As all others above said penetrating oil and LOTS of beating may work. Knowing what I know about them, I would start with a sledge hammer on the flat part of the drum. Beat and rotate, beat and rotate. You may get lucky. Yours don't look too corroded.

On the one I worked on it the beating/penetrating oil method would never have worked because this machine spent it's ENTIRE life loading road salt.

Outboard drum air/hydraulic brakes + road salt are a BAD combination. We either had the brakes rebuilt every other year or just lived without them. Made for some fun loading of the salt barn and loading trucks. LOL.

When you get it apart, be SURE to use lots of anti seize on the drum where it contacts the hub for next time.
