Replacing rear brakes at 19,800 miles

Got my new 23 Tundra around 6 months ago. Zero miles.
Im getting to 20,000 miles and come for oil change and alignment as part of maintenance. Once they are working on it they notice rear brakes are nearly gone. They tell me I need new brakes, to which I think they are being sleek trying to get me to buy new, but sure enough, brakes are gone. They look like they have been running for a very long time. Front brakes are ok. Any issues with brakes sticking or wearing out excessively? I have never had this issue with any of my previous vehicles, including my 22 lemon tundra!

 

I have not, but if I may ask, what kind of gas mileage were you getting during that 19,800 miles?

 

I have been on 14.5 mpg since new the highest that i have seen it go up was 15 mpg.
I do a lot of driving daily on both city and highway and its been stable around 14.5 mpgs

 

There was another member here that had issue with a sticking caliper. Sounds like that maybe your issue. Was there any noticeably worn pad on one side?

 

It looked clean, like a normal wear and tear!
The only thing i have been noticing for a while, which I think might be the problem, would be my self stoping system. It is very twitchy. It has activated multiple times without need for it. Even while having fair distance between vehicles and without a fast speed at the moment of activation!

 

with that kind of MPG, sounds like your brakes were sticking since day one. Sorry to hear but hopefully the dealer will fix it right for you.

 

I agree with that. @Eurodriver had the same problem, getting horrible mileage, then they caught his rear brakes dragging and worn out.

 

This is like the third or fourth person I've heard with this issue on a 3rd gen. Very strange and never really heard of any other new truck having this problem so soon. It sounds like maybe the auto braking, radar cruise, or the parking brake could be a cause. Warranty usually doesn't cover brakes but this soon and before the fronts wear out makes it an obvious defect.

Can you (@Mezadgo) and anyone else (@Eurodriver) with this issue report back with your full ride specs or any mods like lift, wheels, bigger tires, etc? Maybe that could start to show a pattern of the cause.

 

Wouldn't you be able to hear some unusual noise if your rear brakes are sticking all time?

 

Not until it hits the wear sensors or goes full metal to metal. My GF had this problem with a 2009 Camry once upon a time and it was a mess. Before that I had never seen this problem in all my years... except on a motorcycle I kept outside under a cover with infrequent riding. The piston calipers on that bike developed a micro ring of corrosion where they entered the caliper so would never fully retract.

You could check it for heat buildup after you drive a bit. The bad one will be way hotter than any of the other brakes and out or proportion to whatever braking you had done. That's how I discovered the issue on my motorcycle.

 

Yikes! I just replaced the rear brakes on my '13 for the first time at 125K mi. Hopefully Toyota takes care of this for you as that's definitely a defect. I'd bet you're onto something with that auto-braking business.

 

I NEVER replaced the rear brakes on my 2009 Tacoma in the 15 years and 135,000 miles I drove it. But drums. They still had maybe 40% left... because they just didn't do much.

 

Was driving yesterday and felt a big jerk and had to push the pedal all the way down to even START to brake. I was like 2 min from my house and when I got there notice a big leak by the back tire. Turns out the caliper assembly SNAPPED OFF while I was driving. Bolts are still in place. I had already come to a lemon law agreement for fuel line leak and engine, turbos, and alternator replacement with Toyota and was supposed to turn the truck in on Tuesday in exchange for $40k. Safe to say I will be going for additional penalties now.

 

Do you use your cruise control a lot? I know with some other cars with adaptive cruise control it utilizes the rear brakes more when slowing you down with cruise activated, so I’m curious if this may be the same case with the Tundra.

 

Negative. Only thing I started using recently but only a handful of times is the brake hold feature.

Pork chop express!!

 

I would think you would smell the brakes if they were dragging.

 

Do you know why cars with adaptive cruise utilizes the rear brakes more?
