Deuce brake locks up on reverse

[wsucougarx]

I have searched the threads and haven't found my answer. What would cause my deuce to lock up on reverse. Here's the scenario, I was backing my deuce out of the side of the house. Everything was good until I applied brakes I backed up about 15 ft before applying brakes. I noticed the driver side front rear dually tires were locked up. Everything else was moving except that one tire. I managed to back up onto the street. Once moving forward, nothing is dragging and the brakes release. As soon as I stop and try to back, she'll go about 1 ft then boom same set of tires lock up. Go forward no problem again and then back up and she locks up. I then took the truck down the street to turn around. When I entered a large corner going right the same brake decides to lockup (was not applying brakes). So here it is, no problems going forward. As soon as I reverse she locks and when turing a corner she wants to lock. Any ideas? Oh BTW its a 1967 deuce (Fred). Same truck I had issues with at Camp withycombe but she was completely fine on the drive home, no issues w/brakes. She's been sitting for 3 weeks and back to the same brake problems.

On my 170 mile drive home, I stopped and checked the hubs several time. They were all a little warm/cool. So brakes did not drag also wouldn't it be an indication that wheel bearings were ok as well?

Wheel Bearings, spindle nuts, brake shoes broke or incorrectly assembled, broken drum,.... No point guessing.
Time to take it apart and thoroughly look it over to identify the problem and the cause.

Do you have a spindle nut socket?

While you're at it take a good look at the drum itself because whatever is draggin may have damaged the inside of it.

No Doghead I don't have a spindle nut socket. What exactly do I need and where can I get one?

 

[doghead]

The spindle nut socket is a 3" 8 sided socket. They are made by several companies. If you search here you will find most of the brands/part numbers for them. I have an OTC brand, part number 1907, http://www.google.com/products?sour...a=X&oi=product_result_group&resnum=1&ct=title

Your local NAPA should be able to get you one.

Are there any other specialty tools I'm going to need when I go in there. Sorry never opened one of these up before

My local NAPA had the 3" 8 sided spindle nut socket in stock, you could try them...

Just the Budd socket to remove the Budd nuts.

No, nothing else comes to mind.
Chock the other wheels. Be sure to secure the axle with a suitable jack-stand or blocking. Use a drain pan under the axle end when you pull the axle. The whole procedure is covered in the TMs. A complete service at that hub is in order while your there. Wheel Bearings repacked, seals replaced if leaking, brake shoes cleaned and adjusted. Inspect for wheel cylinder leakage. etc. Have you done brake work before?

I am gonna bet the upper pin on the rear shoe has failed.

I have worked on brakes in a VW, 3/4 ton Dodge Ram, Dodge Grand Caravan, but nothing of this size. I just imagine it's probably pretty straight forward. I did just print off the TM brake section on this on. Thanks

Would this cause the lock up on reverse and corning?

 

[doghead]

It sounds like you'll have no trouble then. Just look things over closely as you disassemble and remember that just because it came apart that way does not mean it was assembled correct! Look over the TMs and use common sense. Ask here when you have doubt or questions. There was an update on the shoe retaining hardware, be sure to identify yours as the new style. Get a new spindle nut lock washer ordered when you get ready to order parts(many times the inner tab is broken).

Thank you very much Doghead, your insights and recommendation are always appreciated. I feel a bit more at ease. Thanks!

Thanks Doghead, just printed that one off as well

Bad spring would do it too. Either way that wheel (along with all the others) requires a complete inspection. When my hdwe failed on the wrecker, the shoes ground the drum in two like a cutter on a lathe.

 

[wsucougarx]

Anyone know a source for the brake pad retaining hardware? I've got an email out to whiteowl right now.

 

[doghead]

Memphis Equipment should have them also.

 

[Recovry4x4]

I got mine from White Owl.
