Brake pads ATE or Project Mu
I literally just did exactly this.. Had the BRAKE warning light on the dash and replace rear brakes on Idrive message on my 2019 X3 M40i at 32k miles.. rear rotors looked fine to me.. they were smooth and not grooved.. so i bought OEM ATE PADS and a BOWA rear brake sensor.. $128 shipped from Pelican parts and i was charged 1 hour of labor ($135) at my local Indy shop.. as others have mentioned youtube is your friend.. just a rear pads replacement is a pretty easy job w basic tools.. I should have done it myself but I decided the $135 cost was not worth my time and effort.
During this time I also replaced the brake pads with oem ATE one’s (low dust) and oem brake fluid flush.
Red stuff are absolutely NOT track worthy. Will fade in like 1 lap. Any pads advertised as "low dust" tend to fade pretty fast. Yellow might be ok but I think they're still more of a performance street pad. Project MU HC+ are a good streetable track pad, maybe the best, use them on my Megane RS, no trouble with 20 mins sessions on high speed tracks and trackday tyres (Yokohama AD09). A little squeel at low speed on track but quiet enough to live with IMO.
Regular carbon ceramic brake pads, from Ate and I presume also Brembo, are better than normal pads. Same stopping power but much less heat generation and brake dust.
Project MU HC+ pads. These have a higher operating temp range than Ferodo DS2500 and are perfectly streetable too. I get very minor squeal when coming to a stop if it's been a while since they were used hard. they also have great braking feel IMO, nice and sharp, and perfectly controllable. I use them on a Renault Megane RS 280 Cup, I've used them on track with semi-slicks (AD09s) and they held up great in 15 min sessions. Some minor vibration after the day but that fades away with use (or another hard besdding session). Do not recommend Ferodo DS2500 especially with semi slicks. Might be ok for your first day if you're slow, but you'll almost certainly cook them on your second and get deposits on your rotors. Great performance pads or the street though. On my car I only use them on the front, rears are stock.
I put ATE200 + Ferodo DS2500 pads on my Mk7 in prep for its one (half) trackday, have been on for a few thousand street miles and work well at all temps.
I'm really liking the ATE pads I got for my 340i with the brembo F/Rs.
I went with the pads from ATE and got them fitted today, all in all it cost around 200 USD / 2000 SEK. 2 years ago the mechanic told me all 4 brakes need replacing. Today when they were replaced the rear ones had about half of the material left and the front 1/3.
I did Project MU B force pads. DBA 4000 rotors, Stop tech stainless steel brake lines, Motul 660 brake fluid, radium brake booster brace(a must). Make sure to set those pads in the correct sequence and they gonna rip your face off bud! I had 6 piston brembos also, what a difference!
Even the parts prices are on a different level, ie brake pads with a Volvo logo on them - 160€, with ATE (they allegedly produce the original pads too) logo - 60€...
