OEM rear brake pads worn in less than 25k miles (40k km)

[oscarjfo]

Hi everyone,

I have a 2022 supra MKV 2.0 with less than 25k miles (40k km) and the other day I saw a warning saying that the rear brake pads were worn.

Tires and front brake pads are right, I have not changed any of them. I have not modified the car yet, all parts are factory ones.

It seems very strange to me that the first element to wear out is the rear pads with so few miles. I have not notice any strange behaviour braking, eveything seems to be ok.

Has anyone had the same thing happen to me?

Could anyone tell me how long the rear pads usually last in this car with more or less normal driving?

Thanks in advance!

Most likely, you are kicking in TCS all the time. Driver's with drifting or rally driving style will yield TCS to kick in.

if this was parking brake issue, I believe it will have different code.

After recalling my old memory.. you might have driven with parking brake on.

These cars are rear brake bias imo.

Thanks,

Well, the TCS could be an explanation, but I would discard this because when it is activated a blinking light warn you momentanously (and even you can feel it), and this only happens to me very occasionally.

In the other hand, it's not possible to drive with the parking brake activated, If you forget to deactivate it, the car automatically releases it when you start driving.

I think that a malfunction of the brake system has other symptoms (drift when braking, vibrations, etc.)

So my first idea is symply that this model worn a lot the rear brake. That's why I was wondering if some MKV owner has found the same issue.

Thanks in advance.

Data shows your opinion is incorrect.

Example here under almost 1.5g of braking. Bias is front. Rear bias would make the car want to swap ends all the time. The brakes system bias is dynamic on the Supra so accounts for friction differences. All my data shows it is still front biased all the time, although under some rare circumstances I have seen rear pressure being almost the same as the front, usually when there is a big difference in wheel speeds under braking from the tires breaking traction.

Good to know. ?

I must say the rear throw off a lot more brake dust than the fronts in my experience.

Were you replaced by AI?

It's called being a smartypants, to which @razorlab is King Smartypants.

Op can't drive. too many Nannies intervening. ONLY way to wear down rear pads first.

You probably cut the rear brake sensor. No way you burned the OEM rear pads that quick

Here are my rear brake pads with 25K miles (40k km).

It still remains 3 or 4 millimiters.

might have just been the timed brake service reminder/nag. If you truly cut the sensor it puts you in a limp mode.

Comparing my 25k miles rear pads with new ones...

In my opinion , the pads seems to be worn out. But I don't know why it happened with so few miles taking in mind that the front brake pads and tires are ok...
