Brake Pad Warning Light Just Came On

Recommended Posts

My brake light warning light just came on. My question is do I have to replace the rotors? I see from prior post that it seems to be the case, but I just want to know for sure before I spend an additional $4-500 rotors. Does anyone where the cheapest place to get the set. I have priced AutohausAZ at $607 with out new hardware - this is for 4 rotors, pads and 2 sensors.

I assume this is the brake pad wear indicator light you are referring to and not the brake sysytem malfunction light. eek.gif

No need to replace the rotors unless they are down to minimum thickness.

This generally happens every second pad change.

You will damage the rotors if the pads are not changed soon since the light has come on.

Even so with the light on you can probably drive for another 300 miles before rotor damage will occur.

What you do have to replace is the brake wear sensor unit which puts your light on as it gets damaged once activated.

They say approximately every second pad change will render the rotor to miimum thickness.

Pad wear is obviously dependant on individual driving style.

I've heard of pads being shot after 6000 miles with aggressive driving habits.
