GS Brake Advice Wanted
Also I would like some input on selection of new pads - the dust is killing me! I don't run on tracks, but my street and highway driving is at times very "spirited". Would love no dust or noise, but of course I know those things can't be eliminated entirely. Is ceramic the way to go? And as far as padlets vs one-piece, I would think that one-piece have slightly more surface area, and less edges should mean less noise, but is there anything else I should be looking at?
Thanks,
Tom
Pad shape - I find the 1-piece much easier to change
Anything else - do a search here or on the Auto-x section. You will find more brake pad info than you will ever need

Front and rear 1 piece total $509.00 Subtract $40.00 for padlets.
I did exactly this a couple months ago. I wanted prettier calipers than the silvery-grey ones on my '13 GS, and had gotten VERY tired of the brake dust from the factory pads after only a few weeks. I figured since I was taking the calipers off anyway, I might as well change the pads. I went with Posi Quiet one piece ceramic pads (found them on amazon--a little less than $200 for all four wheels), and have had them on the car now for a couple months. No issues. Every couple weeks I might hear a little squeal as I pull into the garage, but nothing that would have deterred me if I knew it was going to happen ahead of time. I don't track my car, or really push the brakes very hard. If you plan to do so, consider other pads. For what I do, these are perfect. Dust has been all but eliminated.
As for the caliper removal, I was a gigantic failure and didn't plug the lines. I had read that it would work to zip-tie the finger of a neoprene glove over the end of the line, but that didn't work when I tried it, so I just gave up and let 'em hang. Needless to say, I ended up with four tupperware containers full of brake fluid. The good news is that I didn't have any problems bleeding the brakes when I got my shiny newly-powdercoated calipers and installed them. Stuff I learned:
-Brakes are filthy. I don't recommend doing this in formal attire. Maybe business casual. I wore one of my wife's cocktail dresses, but skipped the heels. Safety first!
-Probably would have been a good idea to tape the lines way up in the wheel wells. I read that suggestion after it was too late. Physics is your phriend!
-If you haven't put your car on jackstands before, think it through first. I ended up with a makeshift ramp of wood planks that served as a car ramp for the RF wheel. Only then was I able to get a jack under the front. Also, you'll need to jack the front up FIRST. I felt really stupid once the rear was nicely set on jackstands and I couldn't get anything under the front. I finally figured it out, but it was a pretty novice-looking operation.

-You need a breaker bar to get the bolts holding the calipers off. You also need a buttload of clearance for the rears, so set the jackstands high. It was especially tough to get the proper torque (129 ft-lbs, I believe) on the rears when I installed them. To remove them, I needed to bang on the wrench to break the bolts loose, since I couldn't fit the breaker bar under the car even with it jacked up. Fronts are easier because you can turn the wheels to get to the bolts. Make sure the car is VERY stable on the stands. Even if it is, I wouldn't get under it and yank on the wrench. It's uncomfortable, but you can get the job done from the side. A long-handled torque wrench was key for installation. I also bought some blue Lock-Tite for the bolts.
-If you're doing this alone, a Motive Power Bleeder is awesome to have. I think it was about $70, and SOOO worth it, even for the one use. I had never bled brakes before, and this made it pretty easy. Just be sure to install the brake lines in the correct orientation or they'll leak like crazy--that's self-critiquing. I made sure there were no bubbles whatsoever coming out of the lines.
-Make sure to bed the pads in correctly. Basically it's just a matter of braking almost to a stop several times from various speeds. Look this up on the forum or Google. It took me 5 minutes.
-Even with the failure to plug the lines, I didn't have any issues with the anti-lock system, but if you DO get air in there I hear it can be a problem. Not sure how that would happen, but I didn't start the car the whole time it was on jacks, just in case that system cycles on startup. I wanted those valves to stay closed until I bled the air out of the system. Look up "redneck bleed" if you're worried about this. Seems like that would work, or you could just take it to a dealer to use the fancy brake machine they have. I prefer to avoid the dealer.
I hope this helps. These were some of the questions I wished I had answered before starting the project. Good luck!

As far as the jack stands, I didn't really plan to leave it up for the entire couple weeks. I think I will put the wheels back on and drop it while I am waiting. I know it's a little extra effort, but I think I'd feel a little better about it for a couple weeks.
Thanks also for the info on the power bleeder too, I was wondering if it was worth-while.
As far as taking it to the shop to finish my job, I figure if I were going to do that I would just take it down there the first day and let them do everything. I think figuring these things out is all part of the fun of ownership, right?
Here is the issue I went from padlets to one piece Hawk pads and it looks like the brake clips that were on the padlets won't work for the one piece Hawk pads.
I called the Hawk supplier and he said Hawk doesn't even supply the clips. The retailer says they can get them from a different supplier for another $70.35 now I am up to $497.00
The supplier say this has not come up before.
Ideas please. Price can be misleading if you have to buy more parts the get the job done.
I am disappointed right now on the Hawk products.

That said, I remember reading a few posts on this forum by folks who said they just threw the clips away. My thought is that GM wouldn't spend money on ANYthing they didn't see as necessary for some reason. Perhaps they're only really needed for the padlets?
I'd look into the Posi Quiets unless you're planning on heavy duty use. If you're not a track guy, I think they'll fit the bill.

One person on the forum said theirs came with clips and they just poped them in. Yet the retailer talked to Hawk yesterday and they said they didn't provide or supply clips.
Called Hawk tech line this morning and their "mail box was full" so no help there. Maybe their all at SEMA




I talked to Adam @Carbotech to see if they sent brake clips with their pads and he said they did not. He said I would love to sell you a set of ours but the Hawk pads should fit using the igisting brake clips.
Well guess what he was right.
This is a great example of a forum supplier who has a good long term attitude. Next time its Carbotech.
Not sure why Hawk didn't say that to the supplier but Oh Well alls well that ends well

If you leave the lines open sometimes enough fluid drains out of the system that you drain the master and pull air into the system thus getting air into the ABS module. That means you go to the dealer to get the ABS Power Bleed performed. A lot of mechanics use clamps to close the hoses so they don't drain. That saves the mess of having brake fluid draining all over the floor and avoiding the risk of getting air into the ABS module.

We just zip-tie the lines up here when we're powder coating calipers. It will prevent you from loosing all of the fluid and it is easy to do. I would consider installing some stainless brake lines while you're at it. I know you're not racing but they do provide a firm peddle and reduce stopping distance.
We use and install the Hawk HPS and CP (Ceramic Performance) pads here. I would suggest going with the 1-piece design as they have more surface area and they're easier to install. They perform great without noise or heavy dust. I would probably lean towards the PC compound for your usage personally. We have them in stock and we offer a nice forum discount.
Please feel free to call, email or PM me anytime with questions. Good luck with your project and I'll talk to you soon.

Kind regards,
