Brake issues?
Anyone else having issues with their brakes? Mainly them having a rather short lifespan... my pads were GONE at 15k miles and I had to have the rotors turned as well. Now that I'm coming up on 32k miles, I'm in need of brakes AGAIN. It's only the front ones, too. Right now I'll be driving and either one or both of the front calipers will start dragging intermittently on the rotor, which is extremely annoying AND not supposed to be happening. I don't drive it like a race car, don't slam on the brakes... just normal, comfortable stops and driving. I haven't driven through or exposed them to anything that could deteriorate them, either. Should I just get the rotors turned/replaced then slap on some of the pads offered in the Parts section? Thanks for any insights... this is getting expensive AND annoying.
Though I don't have a xB (yet), I have to replace the pads on my TBird yearly, and occasionally the rotors too (every other year or so). I use carbon fiber pads and cross-drilled rotors, so a complete overhaul of the front brakes (pads and rotors) costs me close to $400. 
I hope the xB isn't as "brake hungry" once I get it!!!

I just checked mine at 11,400 miles. They are just fine. The rotor is smooth, no ridge or grooves, and the pads ar at least 5/16 to 3/8 thick. From past experience they should be good for another 25000 to 35000 miles. Wish my wife's Olds was as good!!

The box being as light as it is, brake pads shouldn't be an issue!
But, driving habbits, and heavy aftermarket wheels will change
that drastically. I'd consider looking at how you drive your box!

Weight of the rim plays a role in braking, but it's also the size and distribution of the weight. . . a common misconception about lighter wheels of larger diameters. Rotational inertia is calculated by the weight AND the radius of the weight from the axis of rotation. So in theory, a heavier wheel of a smaller diameter may still outperform a larger wheel of a lesser weight.
But I don't know how your wheels in particular stack up. If the weight is all on the circumference of the wheel, that's bad. . . but if it is even distributed, than it might outperform a smaller wheel. Might. Which doesn't really say much.

pads are cheap.
do not turn rotors just to "make a smooth surface". Your new pads on grooved rotors will seat-in, and this way you are not throwing out rotor life
changing pads is -ez-, right? and cheap, right? do it yourself!
turn rotors ONLY if they are demonstrably warped out of lateral trueness.
sidebar: in conversation with a taxi driver/owner many years ago I noted to him that his car seemed to be very high milage, but ran great. "over 140K miles". We spoke of the rotors... "NO don't ever turn them. Just change the pads"
-that's my 'authority' for making this statement.
If old mechanics here know better, do set the record straight, please.
bear in mind, your new pads on grooved rotor will not brake efficiently until they've bedded in. Do not punish the pads until they've gained -full face contact- or nearly so. Otherwise you just char those spots of the pad that -do- make contact.

Ok, so before someone else mentions driving habits and brake punishment - I drive it normally, like you're supposed to. Smooth, gradual stops and no riding the brake. As for the last service center, they were done at the dealership and worked fine. Visual hints as to something being wrong consist of my rotors appearing to be made of polished chrome.. looking at them is like looking into a mirror with millions of swirl marks. It's also making the exact same sounds and exhibiting the same symptoms as last time - sporatic dragging of the front brakes while rolling, squeals and dragging while starting from a stop... These are normally cured by a quick rap on the brake pedal. It's also only the front brakes, the rears are perfectly fine and are the original pieces from day one... the last job at 15k miles checked them out fine too, only thing that was addressed was tightening of the e-brake cable.
The rims don't make the list of probable causes because the first brake job was done with OEM rolling stock. I think I'm just going to have it checked out, and if the rotors are fine then I'm going to slap some of those NA-P street pads from the SL store. The reason the rotors were turned in the 15k was due to the pads being completely gone, so the calipers were clamping directly onto the rotors. However, I still have some pad left so hopefully the NA-P's will be the only thing required. Thanks for the input everyone :D

SciFly, I don't *know* myself, but the old wrench benders who maintained our company fleet of cars and trucks would have agreed with that taxi driver - they didn't 'turn' rotors unless they were REALLY bad.
Where they right? I dunno. I do know that our fleet was well maintained and safe...

I'm surprised your pads went so quickly. 15000 miles is rather a short time.
I would make sure the dealer is aware of your concern. If the car was dealer serviced why didn't they pick up on the brakes before 12,000 miles? If they would have been reported worn out at 12,000 miles they would have beeen covered under the warranty.
Even though it's a maintaince item, during the first 12 months or 12,00 miles, they usually are covered.

On the other hand, you should be glad you don't drive a tahoe. Man, those things love eating pads and shoes.

xtremeOrange what dealer do you go too. Maybe you should try a brake shop not the dealer. When somebody comes back with the same complaint they usuallly let the tech did it last take a look at it again. Maybe he does not know what is wrong so try something else. True story my brother went to have his truck (Mazda) inspected for the 30,000 mi and the tech at the dealership sayed that every thing was fine. A week later he moved to D.C. and notice his brakes were not working as good. He took it to a brake shop up there and the guy told him that he should of had them done a long time ago and that there was almost no brake life lift. The guy was shocked that he made such a long trip. It just goes to show that not every tech knows what they are doing.
