Brakes squeaking new pads?

I just purchased a 2007 335i coupe. My breaks are squeaking as I slowly break. I'm assuming I need new break pads. Does anyone know of a good site or maybe a link to ebay to buy some good pads. I'm assuming the dealer will charge a s**** load. So any information would be greatly appreciated.

Thanks

not sure squealing brakes are a sign they need replacing, BMW doesnt put the churp stick on pads, BMW's have a brake pad sensor that should come on when the pads reach a min thickness. if you have the tools and the knowledge, take the wheels off and look at the pad thickness, there could be another issue why the pads are squealing. And yes you would be 100 percent correct! the BMW Palace will charge you a S**T Load to do a brake job, Pads will be in the 150-200 dollar range(just a guess) and they also have a mandatory replace the rotors too. I would stay away from ebay buying break pads and rotors, several BMW aftermarket sites that others have used to get brake pads and rotors and dont forget the pad sensor too!

If your pads are OK fix the squeal. Brakes squeal because the pads vibrate against caliper not the rotor thus the reason you put brake squeal eliminator which is usually a red plastic bottle maybe 6 oz that acts like silicon. Put that on the pad where it contacts the caliper. This is true for new pads too. Also if the edges are not chamfered that will add to the squeal. Most pads these days are beveled to have a chamfer.
Be sure to have your rotors mic'ed. BMW rotors are sacrificial and that is why they brake so well.
Visit our forum vendors down in the classified section and get quality pads and rotors if required. I tend to use Zimmerman and Brembo because those are both OEM for BMW. Pads are up to you but BMW pads 2009 and later are low dust. New pads should be low dust too. You can use alternate pads but I would recommend a good ceramic pad to reduce dusting and still have a good performancing pad.

You have been given good advice but if you have any question feel free to ask.
If you have basic DIY skills replacing the brake pads and rotors yourself is not a had job at all. BMW has some of the easiest brakes to change out there...

could be rotors. as i recently learned, dealers often change pads without doing rotors under the bmw included maint plan. the car will brake safely but squeal. however your mechanic should be able to determine the issue fairly fast.

My brakes have squealed since the car had about 20K miles on it. Dealer is worthless, take it to an independent!

9 times out of 10 on a bimmer its due to the brake pad guide and not the friction side. The "ear" that slides on the caliper guide must be lubricated with with eitehr copper paste or the bmw paste. This is not the same as the rubbery crap people used to splatter all across the back side of the pad.
