Brakes

I’m going to replace them. I’m surprised too considering the low mileage. $87.00 per drum isn’t astronomical, but it’s the fact that I noticed it at 39k. My main concern is what happened with my truck leading up to the point that I bought it at. Other surprises? Already have had the rear differential replaced under warranty after breaking teeth off of the ring gear.

Thank you for sharing your knowledge.

 

Is it a E-locker?

 

Yes

 

Those have a smaller ring gear and inherently a little "weaker" especially when you bump up the gear ratios. But still shouldn't of failed already.

 

First I'm not sure what you are asking about. From my many years of experience you shouldn't have to even touch the rear brakes until you hit about 100K miles.

So it had New Brakes when you bought it from Toyota at 39K miles.
You now have 50K miles and the drums need to be turned with only 11K on the brakes?

If the drums are 4 mm under the maximum diameter then you can still machine 4 mm off and be in spec at the maximum.
4 mm is a lot of metal to be cutting from a drum.
