Drum replacement

I had a weight come off a drum, and I believe its causing a vibration at highway speeds... is it OK to replace just the drums? or is a full brake job required?

2009 TRD-OR 4x4, 113K miles. Shoes are currently at ~5mm (last inspection by Toyota in June). Any info would be appreciated. thanks

 

Might as well do the shoes while your in there... they are cheap, and if you use your old ones it could cause grooves in the new drums.

 

Ok. was hoping it could be an easy swap out, but if it'll cause problems i'd rather go the safe route. thanks.

 

I have some rear brake parts for sale. New in box https://www.tacomaworld.com/threads/massive-parts-collection-for-sale-taunton-ma.523587/

 

The old shoes will only cause grooves if they wear down to the metal. If they didn't cause grooves in the old drums, there's no reason to suspect they would cause grooves in the new drums. Yes, you can just throw on new drums, but I, too, would replace the shoes if they have over 50K. And you don't have to replace both if you don't want, just the one missing the weight. But do measure the other drum's run-out.

 

Like the others said, you have most of the work done by the time you have the drum off, measure the shoes, and if they are below half worn, I would replace them. I don't know if the rear brakes have manual adjusters, but make sure the other side is adjusted the same as the side you put new shoes on.

 

How hard is it to remove the drums? The drums on my old 91 were really tough to get off.

 

Easy, you use a bolt (m12?) in the threaded holes and it pushes the drum off.

 

Weights come off of the drums all the time, unlikely the cause of the vibration. Check ujoints closely.

 

Had one of mine come off when installing my lift, one of my buddies who helped on the install tacked it back on. Did the job...

 

The rear ends of these trucks never need brakes Lol! Weld the weight back on!

 

I had a weight pop off mine too, I didn't notice any difference. Its a pretty minimal weight very close to center of rotation.

 

Only reason I noticed mine was one of wheels seized on a bit so took a hammer to it and heard the *ting ting* as it dropped, ignored it til I found it on the floor while taking the leaf pack apart

 

I dont have the weight. not sure when it was lost.

 

its a pretty minimal vibration too. but just annoying enough to want to get rid of it

 

I wonder if sticking some of them super strong magnets would help? Look for anti-corrosion treated magnets as they will rust otherwise.

 

That's not a bad idea... Any clue approx what weight I would need?

 

No since we don't know the size of the weight that fell off. Maybe get a few magnets and add the one at at time until the shimmy goes away. Then, as a permanent solution, weigh them and have a welder tack on a weight.
