Brakes

After replacing the brake pads and rotors on all four wheeles a clunking sound is heard after applying the brakes the first time going forward and the first time in reverse. What could be causing this?

In what order do you bleed the big brembo brakes? I'm bleeding them to change out the fluid, so how much should I remove from each caliper?

Took the CayenneS in with 16k miles, to have the 20k service done at dealer. Service tech says the front brakes only have 15% pad left, and recommend changing for $950. The brake sensor never came on, and one of the postings on PCA says the sensor light should come on with 30% pad left. I asked to have the sensor replaced under warranty, and dealer says their electronic diagnostic check didn't indicate any failure, so can't replace just the sensor. Does this make sense ?

Do you know of an aftermarket supplier of dustless brake pads for a 2005 Cayenne Turbo? The OEM pads are horrible!

What is the minimum thickness of the front brakes rotors?
