Help: Brake Replacement Situation
Went in for a brake evaluation knowing that the brakes were going to need servicing. I first went to Sears where I was told that the pads needed to be replaced while the rotors could be resurfaced. I visited another shop today for an inspection and was told that the brakes were in awful shape and everything needed to be replaced (all pads and rotors) and quoted $945. They were "surprised" that Sears had even let me drive away after they had completed their inspection. The Sears inspection had showed about 1.5mm left on the pads (I know, that's bad) while the other shop is telling me there is 0.
I've made a few calls to some other shops and have been quoted mainly around $600-$700. Is there a significant in the quality of brakes that I choose to get. Last shop I spoke with wanted to charge $810 because they wanted to put original rotors on it rather than something aftermarket. Does that make a difference?
Sorry for all of the questions but any help is appreciated as I'm not the most mechanical guy!

I buy from Brake Motive on ebay. They sell drilled rotors (zinc so they don't rust) and ceramic pads (no dust issues). I drive my car hard, I've put the brakes on my diesel, my 4runners, even my Mustang's. Never had an issue with the parts. I used them on my IS350, $202 SHIPPED for front and rear rotors, pads, clips. Save yourself $500+ and do it yourself. Brake's on this car are NOT hard.
Use a C-clamp to move pistons back in on the surface of the old brake pad. It's 2 bolts per caliper and a simple spring/pin mechanism to remove pads. While you are in there, GREASE YOUR REAR SLIDER PINS. They notoriously seize, mine were an my car is out of the rust belt/low mileage car. Otherwise, simple hand tools, jack and a single jack stand if you do one corner at a time will suffice.
This is the link to what I purchased; http://www.ebay.com/itm/FRONT-REAR-D...53.m2749.l2649
Not endorsed or anything by these people, but I like cost effective things that work. Good luck.

Hi XSV:
Regarding rotors, the Lexus dealership here in NYC gave me an estimate of $790 for new pads, as well as a resurfacing of the rotors on my 2011 IS250C. Naturally, I won't bite. However, because all pads are allegedly 3MM, I will start getting serious about replacing them. I have two questions:
1. What is the minimum width for pads before it is recommended to replace them. (I was waiting to hear them squeak before doing anything. Is that safe?)
2. I'm reluctant to have my rotors resurfaced for no other reason other than to smooth them out for the new pads. In your opinion, is it necessary to resurface them whenever new pads are installed?

You need to at least sand the glaze off your rotors so the new pads can bed to them. No reason to not smooth them out by resurfacing them at the same time. Or do what I do and plug new rotors on with pads. You can get good after market rotors for the price most places charge to turn them.

This is not needed if you are using the same replacement brake pad compound. I also skip doing that when changing between track and street brake pads with different compounds without any ill effects per advice from others on this forum, but some may argue you should do this when changing pad compounds. But don't use sandpaper since it can cause rotor issues, use garnet paper instead.

Note:
Hawk Performance burnishes its High Performance Street brake pads as a final step in the factory, but all brake pads have to be bedded-in with the rotors (new or used) that they will be used against. Properly bedding-in new brake pads results in a transfer film being generated at the pad and rotor interface to maximize brake performance

To be clear, I wasn't advocating against bedding in new pads. I still go through the manufacturer's recommended pad bedding process after changing brake pads but without doing anything to the rotors. YMMV if you do this when switching between different pad compounds on the same rotors but I was just sharing my experience.
It is unnecessary to do anything to the rotors if you are just replacing pads with the same compound that was previously used on those rotors according to Carbotech. You should still follow the new pad bedding procedure though. That is assuming there is no vibration under braking and the rotors still exceed minimum thickness.

Also Stoptech advises against using regular sandpaper on brake rotors:

Proper USED brake rotor bed in procedures:
- If rotors have been previously bedded with Carbotech brake pads, then bedding the rotors again is not necessary.
Also Stoptech advises against using regular sandpaper on brake rotors:
The obvious question now is "is there a "cure" for discs with uneven friction material deposits?" The answer is a conditional yes. If the vibration has just started, the chances are that the temperature has never reached the point where cementite begins to form. In this case, simply fitting a set of good "semi-metallic" pads and using them hard (after bedding) may well remove the deposits and restore the system to normal operation but with upgraded pads. If only a small amount of material has been transferred i.e. if the vibration is just starting, vigorous scrubbing with garnet paper may remove the deposit. As many deposits are not visible, scrub the entire friction surfaces thoroughly. Do not use regular sand paper or emery cloth as the aluminum oxide abrasive material will permeate the cast iron surface and make the condition worse.
