TEXT_OF_5_STARS by Mark
"For all Audi A5 and others with dreaded brake squeal!!!! If you check a lot of Audi forums you will find that tons of people have major brake squeal, this leads people to take it to the dealer many times and problem still persists. I remedied the problem with a quick front brake pad change out using Hawk low dust pads. It always happens more in the cold. It is the cold time of year here in Vegas and not even a hint of a squeal, did this change on my girlfriends car, it took 30 minutes and I look like a hero. I highly recommend the Hawk low dust pads, and on top of it there was no loss in stopping power!!!!! Actually stops great, so no squeal, that is a win win."
