Hi, I have a 1997 F150 4.6 Ext cab, 4x4.

When I was replacing my rear wheel bearings and installing a lunchbox locker several months ago, I noticed my rear drums wouldn't even stop the rear wheels when they were in the air and the truck was in drive. I couldn't figure it out then as I was under a time crunch. The pedal has been a little soft since I've owned it. I honestly just use the truck to go to the dump and home improvement stores and the truck stops OK.

But now I have a 19' boat with no trailer brakes. I've been towing it with my Kia Sorento and it does alright, but I know it would be a non-issue with the F150 if the rear brakes worked.

It's a northern truck I believe, lots of (mostly) surface rust underneath. I surmise that the adjuster is rusted and in-op. Does that seem like a fair summation? Anything else to check? Brakes have been bleed, I've just never had to trouble shoot drums before.

Thanks.

 

The adjuster on drums is a star wheel that is engaged when the brakes are applied in reverse. If it is frozen or missing, no adjustment. Can you turn it? Is there a lever/cable gizmo inside to engage it? How are the linings on the shoes? What do the drums look like--big ridge, scored, cracked?

You can find Youtube brake jobs all day with some even by vehicle.

Otherwise, find a trusted brake shop.

 

Thanks for the response!

Well, this was quick, my son let me stick him in the truck so I actually was able to take a look. The adjuster(?) on the bottom is pretty rusted and the teeth are rounded to the point that I can spin it in both directions, very easily by hand, and move the shoes in and out. That seems to be the issue.

I need to replace the gear on the adjuster, or maybe the whole thing? Also, the little lever that should block movement seems to have some wear on it as well, so I think I should replace it too.

What are the names of the parts I'm looking for?

Oh, and pics:

 

Once again, I answered my own question, because I'm a big dummy.

All the adjuster hardware come together as a kit and it's around $9 for each side at most auto parts stores.

Maybe this thread will be helpful to some one experiencing the same issues.

 

Also, if you use the discount code 'TRT30' on Advance Auto's website, you get 30% off. So that means it only cost me $15 to go from in-op rear brake to functioning.

The more you know!
