Brake Pad Warning Light Just Came On

[cayenneturbo]

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.

Thanks

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

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.

How long do the rotors last? Or how often are the brakes replaced on the Turbos?

[bigbuzuki]

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.

We bought the car last July with 50K, it now has 66k. Would you say the likley hood is that the car has had it brakes replaced already? I am trying to figure out if this is the 2nd 3rd or 4th brake change.

Best way is to visually inspect and measure your pads and rotors, this will clarify your situation.

How many brake sensors are there? 2 or 4. I was about to buy from AutohausAZ and their site states (2) per car in each of the front and rear sections.

1 per corner... 2 front and 2 rear.
