Brakes

Does anyone have any suggestion on better pads/rotors for these new cars? I am wondering if anybody has replaced their brakes yet, and if they have used aftermarket parts? The stock brakes seem to work ok, but they have the usual mushy GM pedal feel.

I'll probably go power slot and something near ebc red quality for bite & low dust. I like them so far on my f-body.

Anyone know offhand if they are ceramic or semi-metallic pads? They seem to be a little dirty for ceramics.

I did the police upgrade on our 12 and really liked the results. With the 20's on our 16 there is so much room for larger brakes that it is a shame not to take advantage of it. The factory brakes aren't bad. But after driving a few BMW's, it is really nice having the great stopping response that those big brakes give you.

IMO, Chevy has an outstanding car here that would just need a few things to gobble up some European car drivers. Bigger better brakes. An optional AWD platform. And an optional forced induction package. These could add considerable cost to the cars, but they would be competing with more expensive cars as well. Frankly, the Malibu would be a pretty good package as well for the smaller car market.

I will beg to differ! Our 14 Impala and 14 Silverado will put into the windshield. My 04 Alero with 8500 miles total takes more time to stop and it's the lightest vehicle we have. Brakes were decent to not so good and I hear they were like an eraser.

My 1970 Cutlass with power disc/drum with organics, take a while to stop but that stands to reason.

This is what I put on my car and they fit perfect and perform way better than stock. You get all 4 rotors, drilled and slotted, plus pads. Rotors are zink plated so they don't rust. Only bare metal is where the pad contacts the rotor and wears the zink off.

The original FNC treated rotors are excellent. The pads are ceramic. The OE pad is quite good when treated well. rust build up and contaminants really kill them

As far as aftermarket pads go I run and recommend Hawk HPS on all my cars. Excellent initial bite but not grabby, better fade resistance then pretty much any stock GM floating caliper pad, and they dust a very light grey usually. easy to clean.

I prefer the stock rotors on this car, like i said, I think they are excellent. I mean original GM rotors, not ACDelco advantage or anything.

If I was to go aftermarket, Id recommend Raybestos Advanced technology, or Centric High Carbon rotors(Centric or StopTech rotors that start with 125 or 126 as the part number)

You dont need and shouldnt get drilled rotors IMO. street cars dont need drilled rotors, modern pads are very good and dont need the holes, and Id rather have the extra mass than some holes. Brake rotors are heat sinks, drilling holes in them rarely makes them MORE effective. Id consider slotted rotors only if it was the only way to a high quality high carbon or non-Chinese rotor

If your brake pedal is mushy, youve probably got air buildup in the system. A thorough flush/bleed of the system will likely give excellent results. Use a pressure bleeder, youre going to want to get about 6oz or more of fluid out of each bleeder, doing this manually will SUCK

I have been doing some digging around. I think there is a caliper that should swap on from GMs parts pin. 4 piston Brembos versus our shitty one piston.......those and some fresh rotors should be the ticket.

There isnt one that swaps on with no mods or other part changes.

An adapter is easy for me. I have a full CNC shop. The ATS with the heavy duty brake package has the same size front rotors, but with the 4 piston brembos.....Along with a few other GM "redline" or performace models. If guys are throwing the ATS/CTS-v 4 pistons on Subarus's etc, I don't see why they cant be put on another GM product.

cadillac brakes on an 8th gen have been done (i've seen an article on it in the brake section perhaps). normally on the 8th gens everyone goes with the police package upgrades (about a 1" larger rotor, keep in mind rim clearance when going bigger).

as for 9th gen, i've not seen many or any complaints on braking performance per these forums. not to say it couldn't be made better, just haven't seen any information pointing to upgrades made easy through existing GM parts.

never said they couldnt, but why would you want the ATS/CT6/CTS brakes? its just a fixed caliper compared to our sliding. No real upgrade in performance. No appreciable difference in pad size, reduced wheel fitment when using. Just a change for the sake of change

Id be going with something like a Wilwood FNSL6R in 4.04" area piston(for a higher effort pedal feel) clamping a 365mm BMW E92 rotor, or better yet a full on Alcon MONO6 setup for the 3series. (same bolt pattern for rotor, just need a centering ring, and same exact piston area as our stock caliper)

Or you could go cheap and just put some Camaro SS 345mm rotors and calipers and and even get Chevrolet branded calipers. Even cheaper still just rock some Caprice 345mm rotors and calipers, they fit inside stock 18" alloys based on my testing
