Drum brakes hanging up after sitting a month or two

Recommended Posts

I seem to be having an issue with the front tandem passenger side brake shoes hanging up and not releasing.

The chambers appear to be fine, it seems as though it is the shoe linkage.

I would be so grateful if some of you might like to share some wisdom on the subject.

Mine done that the last time I moved it. Had sat for months. Took a few hundred feet to free up. I would also like someone's option on this.

When we lived in Florida and let the truck sit for more than a week, it was common for one or more brake shoes hanging up. Chalked it up to high humidity rusting/bonding metallic shoes to drum. Always broke loose when I’d put it in 1st.

There is a way to release them by banging on the drums but I don't like to climb under the truck with the brakes released, fear of the truck rolling once the stuck pad released is usually why. Guess you could block the tires. I have heard that some use a pipe and go thru the wheel openings. I just move forward or back till it pops loose

Is it happening after it sits or is it happening even after a day or 2?  

If their dragging or sticking regularly, I'd start with replacing the brake can, or just have the front brakes replaced.  It generally doesn't cost much, and would be the only time you would ever have to rebuild them.

Mine also does this on the right side. Its very hard to brake free after an entire winter. I am considering cageing the brakes this year.

Use a few flexible cutting boards between the drum and the shoes. Chock the tires for insurance.

Definately only happens after setting for several weeks to a month or more.  Becoming very consistent though.  I will double check the S cams and make sure that I am not missing them while living the chassis.  I suspect I have overlooked them.

It is differently the brake shoes rusted to the drums.  In my area it would only do it in the winter after rains. When I was working and we would get a fleet of trucks back in and sat for a period of time, we always would have to beat on the drums to get them to release.  We had a sliding bar hammer about 6' long that was for breaking tire beads that worked pretty good.  
My HDT will do it after setting in the winter.  Most of the time I can get them to brake loose by going forward and reverse.  Be ready for a loud bang when the release.

I know a guy that would slip wooden shims in between the break pad and drum when he parked his semi trailers for a long time. They always rusted. This helped. I don't know why you couldn't do it with a HDT. I would chalk the wheels just for extra insurance.

I hope to get to the brakes this weekend.  Been remodeling a bedroom in the house after my youngest son moved into his own home.

Now the nest is empty, accept of course the Mother in Law🧓

If you have the time and energy to cage them, then I would try Darryl's solution of the flexible cutting boards or those flexible silicon baking sheets. The baking sheets can handle temps from the negative numbers to 500 degrees.  They are cheap and I bet you could cut a workable shape easily. They aren't real thick and would be faster and easier to remove than uncaging them. Of course that all depends on how tight your brakes are to start with. I've seen shoes adjusted so tight I couldn't get a piece of paper between them and the drum. 
I guess that is where I get lucky, having my truck stored at home. I try to get it out for a drive at least once a month, keeps the diesel stirred up and the rust off the brakes.

Well since you are working in the house, what is she doing? Send her out to do the brakes. Even Mother in laws need to earn their keep 🤣

Big5er I would have to dig it out of 3 feet of snow and put on chains to take it for a spin. I think I will try the flexible cutting board this year I can always back off the slack adjusters. This spring when I got the truck out I left both spin and skid Mark's on the cement. This year it will be on plastic covered dirt so hopefully what ever I do works.

The 1/2 to 3/4 turn of slack when brakes are adjusted correctly sets the shoes pretty tight to the drums. .018” to .025” shoe to drum clearance doesn’t leave much room for kitchen cutting board pieces.

Check your brake OEM’s specs for your shoe to drum clearance.

What solves the issue quickly is full lockers 😊

Old man here told me Pam keeps his brakes from sticking. But Pam caught him with a young gal. Left him and he can't get his 19 year old to work on his brakes.
