I have closer to 1/4" on the rear. My mechanic was trying to sell me rear brake pads, until I told him, there is no indicator for low rear pads. These pads were changed 22.5Kmi ago. The dealer topped off the fluid then. I didn't know the indicator is the same for front pad low and fluid low.

 

WTF? It's not brake fluid that triggers the brake pad alarm. The pads have sensors in them - metal strips that allow a signal to pass through the pad. Wiring hooks up to the pad from the car that sends a continuous signal to the pad. Once the signal is broken (ie. the pads have worn down enough to wear through the metal strip) the brake pad warning goes off...

Worn rear pads (no sensor) will never bring the brake fluid low enough to trigger a low brake fluid warning unless you are low on fluid to begin with

 

Front pads only have senors. Rears don't.

With the amount of brake fluid that comes from the factory, the low brake fluid warning will light prior to the rear brakes totally worn out.

 

That is not a definate statement

 

Crazyhawk, glad I could help. Sometimes you just need to read through the BS.
