View Full Version : Brakes on 2010 3.0

Hi all,

My original brakes are starting to tell me they want to retire. I went to parts store for rotors and pads. They asked me the size of the rotors. I have 17 inch wheels and I was wondering if someone would know this information (saving me the tire removal...:o). Also, without going to Brembo brakes, what would you suggest for great stopping power and durability without having to go with expensive Brembo kit?

Under your spare tire cover is your rpo code list. You should be looking for je5 or j55 and they should be able to find the correct size rotors. I've always gone with oem or acdelco's pro durastop. I usually use acdelco's online catalog to get the part numbers and then order from amazon. Saved a bunch of money doing it that way

If you have standard brakes (JE5), the oem part numbers are:
Front rotors: 20808620
Front pads: 22825195

Ordered last month fron acdelcodirect. Fast shipping and good service!
