Please elaborate a bit about the installation. There has been speculation that the chronic squealing originates not from the pad/rotor interface, but from the pad/caliper seating. Did the new pads install with any lubricant or adhesive interfacing the calipers intended to minimize movement and friction?

 

If was pretty straight forward install. Nothing special really, especially if youve ever done brakes on a car, or any other type or work ie oil change etc.

I didn't remove rotors so that will add a little bit more work, if you're doing that.

Fronts are simply 2 (21MM I think) bolts on the back of the calipers, then there is 2 pins on each caliper you tap out which releases the brake pads. Make sure to be careful of the sensors unless you have new ones of those. Mine had not been tripped yet, so I re-used them but the could easily be ripped out if you're not paying attention. For the pins you'll need a small 1/8"-1/4" punch or maybe nail, small screwdriver, with hammer to tap the pin out from the outside of the caliper tapping it in to the inside where you just jiggle it out. There is a tapered pointy end of the pin you push it out from that end, it'll make sense when you see it but the tapered end is goes on outside of the caliper closest to the wheel, and the pin has kind of a nail head on the back that stops it so when you put the pin back in youll tap from the nail head end.

From there just clean the caliper really well, there was a ton of dust of course. I cleaned the pistons as best I could and pushed them back in with the old brake pads in still and prying them apart to push the pistons back in.

I applied high temp disc brake grease to the channels where the pads rest, cleaned the clips really well, applied some grease to the piston area, and some anti squeal paste to the backs of the pads.

Don't forget to clean and grease the 2 locking pins, tap them back in, you may have to push and kind of wiggle/the pad up into the caliper to tap the pins back through both caliper holes and both brake pad holes, but with the pins back in the pads are then locked in place in the caliper exactly where they're supposed to be.

Then carefully slid the caliper with pads & pins in place over the rotors and put the 2 bolts back in, torqued them down and thats it for the front.

Rears I think is 2x 13mm caliper bolts, but you'll need another wrench on the sliding pin to keep it from spinning. I did have to release the parking brake to get the caliper off. If youre doing rotors, youll need to also remove the 2 bracket bolts (I think 17mm?, maybe 19mm, not sure I didn't remove them), and the screw holding the rotor in place.

Same as fronts, cleaned everything really well pushed the piston back in applied some grease to the track for the pads, greased the floating pins put them back in the caliper bracket. anti squeal on the back of the pad, put them back on.

Very straight forward, nothing eventful, or out of the ordinary. With how much the brake job costs, it's actually very simple and straightforward.

Get the wheels back on, get the car back on the ground, when you first start the car make sure to pump the brakes a bunch to get the pistons re-engaged and in place then give it a little test drive.

The pads did not come with anti squeal or grease so youll need that, some brake cleaner , or whatever method you like to clean everything up. Try to get brake cleaner that wont melt the caliper paint, but should be ok.

Like I said with my M5, they squealed horribly also, and I don't know what the cause is, ive gone around and around with BMW about it, they say its the nature of performance brakes.... but at any rate i've had new brakes put on that and its quiet for 5-10k miles then starts up again, so we'll see with the G63 how long they stay quiet.

 

Thanks for a very detailed procedure. I'm sure this will assist others, and maybe encourage some to take on the repair themselves!

I have always been suspecting of the pad to caliper interface as the source of squealing. The pad lubricant you applied will surely help. Keep us updated with your experience!

 

No problem, it's very very easy. If you have even a novice level of any thing mechanical it can be done on your own in my opinion. If you've changed your own oil or changed a tire you can do this in my opinion. This is maybe 1 step above an oil change, but really not hard at all.

The hardest part will be if you don't have air tools or impact gun etc, the caliper bolts can be pretty hard to break loose, and may need a long extension bar or something to add leverage to brake them loose the first time.

Its tough to say where there squeal comes from, ive heard its the calipers, ive heard its the pads, ive heard its rotors, ive heard performance brakes get some light glazing from city driving then squeal until the glaze is removed, ive heard its vibration, and everything in between.

On the M5 many have done aftermarket pads like these ones, and even some really high end performance pads guaranteed not to squeal, but after a while they start to squeal again. So we'll see hopefully they stay quiet for the duration. I'll be happy even if theyre a little quieter and having no brake dust.

For me it's a toss up which is more irritating the brake dust or the squeal, but if I could get rid of either it's a win, if I can get rid of both?? Im doing cartwheels!

So far I have about 5 miles on them, and theyre quiet for now.

 

Oh forgot to mention to be very careful with the calipers while theyre still connected to the brake lines etc. Do not let them hang from the brake line, the calipers are huge and very heavy, so they need to ALWAYS be supported as to not dangle and potentially rip the brake line out.

Here is a YouTube video on the fronts. The rear is the same process just with out the pins needing to be tapped out, and the floating caliper pin bolts need to be held from spinning. 13mm bolts.

The video is not in English but watching it will give you a good idea on the process (for the fronts) at least.

 

If I remember correctly, you have to enter the service menu to move the parking brakes into the brake pad changing position. Here's a link showing how to getinto the menu.

 

3000 mile report. No squealing and 75% less dust. Stopping bite, I will give a 90-95% compared to oem pads.
I did not replace rotors yet.

 

I bought These brakes for my 2020 g63 cause my brakes squealed in ways you can’t imagine and let me tell you …. BEST decision I’ve made . I haven’t heard a single sound from my brakes since I bought them and they have been just amazing . I used to be embarassed driving around and stopping the squeals were horrible. The disc Italia brakes are AMAZING

 

Where are you guys finding these? I am not seeing them anywhere.

 

link is further up in the thread. Have to contact them direct. Brakeworld.com

This is the email I used and they handled the rest.

Any long term updates? I just ordered a set.

Also, did you replace the brake wear sensor or re-use the old one?

 

25k+ miles & still good on pads. Replaced pads & sensors.

 

perform well but break dust is still a major battle. Really wish Akebono had a set that fit.
