Are there no longer "low noise" high performance brake pads? I recall ordering a set for my E46 M3 that squeaked and that solved the problem and didn't impact braking performance.

Performance wise in normal driving it feels a bit easier to stop now then with 50i stock brakes - but keep in mind 50i brakes are very good to begin with (they are 2 piston design in the front), so any improvement on top of them is an accomplishment imho. Also, in several instances when I pushed the car hard - difference was more obvious. I might try different pads - for now I have used stock oem ones that came with calipers.

Only one negative - now my brakes squeal at low speeds - like when in stop n go traffic going very slow and stopping. Haven't looked into solution yet, but F85 folks complain of that too, as well as Porsche Cayenne folks lol - so I think that is something to do with bbk - either drilled rotors or pad material, not sure yet, but that squeal comes with the package - authentic experience

Squealing is high freq vibration in the material. Pretty Normal for rotors and pads of this size. Good video by Porsche on it on YouTube.

cool, the more you know...

Since your front rotor is bigger than original and the rear is the same, do you feel the front end dip down more than before when brake hard? Or it is the same?

These calipers are bigger than my shoes. Dush is definitely a bad influence here

Yeah but there not bigger than Shaq’s

Just completed this install. One of the easiest bolt on upgrades I've ever done, total install took about 1 hour.

All of the time was rebuilding the calipers as they needed a little tlc. Changed out the inner caliper seals and boots, there were some gouges on the exterior that I used quiksteel on and sanded down.

I haven't coded the car yet as I never like introducing multiple variables at the same time. I've driven the car for about 30 miles and it feels great, very linear and braking feels much smoother. My old pads and rotors were fairly new and oem to help give a comparison.

Total cost was
600 for both calipers
130 pads (pagid)
60 rotor shields
50 for paint (g2)
30 for seals
20 for pins and clip
20 for fluid
260 for both rotors (fremax, nothing sexy here but I didn't want excess dust or sound)

To get a full bbk upgrade on the front for under $1300 is insane to me but I'll temper my positive expectations till I can put a few hundred miles on the car.

Well done. Any picture? I have not start mine yet but will be soon. Will you front end dip more compare to before because the brake caliper and rotor are bigger?

No, the bias isn't that much different between front and rear.

How the hell did you manage to talk them into replacing them 4 times? I've had like 5 BMW's now and every time I've gone in for a brake squeal they blow it off and tell me "its normal" which it isn't normal but definitely common

[menelaos]

Looks like DuSH has vanished from the forum...... No postings in almost two weeks!
Guess he found better things to do

I have a great relationship with my dealership and I do not demand or beg for anything. I simply state the issues and concerns in return they do their best to accommodate and resolve the issue within a timely fashion. They also replaced the batteries twice, all injectors and plugs, along with many other things. The E70 X5M was the most problematic BMW product I ever owned but the support and service kept with me the brand and I owned several other vehicles afterward.

Apologies if this was already covered somewhere in this thread, but for those of us with 35i or 35d models, would the E70 X5M rear brakes bolt right in as well?

Edit: Looks like they are, so I picked up all four.

[DuSh]

I apologize for been away - I'm in med.school and just finished 2nd year, 3rd year we are going to do rotations in hospitals, each month different specialty and I know I'm not going to have time at all, but I'm trying to read forum and post from time to time.

Wow, it's good to see some of you did this mod and upgraded front brakes! We are accumulating community knowledge on different mods! Which is rare to find in X5 luxury SAV world. As most are either afraid to touch expensive SAV or just use them as a family car.

I recently drove very aggressively and I can say Brembo brakes are definitely stopping me faster than before. Couple of times I got burned smell after such spirited drives - I'm talking really aggressive driving. For just front brakes - it's as good as it gets imho (considering everything, looks etc).

Yewlock, man you will need bigger rotors again for those Brembo brakes, the ones I sent you are for 50i brakes - I'm sure you know it, I'm just stating it just because I saw your photo of Brembo calipers you bought.

Yes, they will, but you will need bigger rotors accordingly (and pads of course).

Thanks DuSh. I grabbed all four calipers and pads from an X6M and have new F85 rotors to mate them with. I'll post up once it's done.

Great!

P.S. Hopefully, you already know it, but just in case - there's a shorter installation bolt that holds rotor in place to the hub required for f85 rotors (for front if I'm not mistaken) and holes for that bolt don't line up on rear rotors - so they just go without that bolt. It's not a big deal - it's only used during installation to help keep the rotor in place before calipers are bolted. Just thought to mention it (maybe someone in future will run into this thinking it's an issue, while in reality it's not an issue at all)

P.P.S Also there are only 2 sensors: 1 per axle and it's fine to reuse them - no need to buy new - they are essentially just a piece of wire with metal clip at the end. AFAIK all sensors are same for x5 or x5m across all engine models

Hi adding F85 rotors next week at a private shop (dealer wont do it). So rear rotors from F85 are super ok, no issue at all? Will it be possible to install without too much trouble? Am afraid that im told rear wont fit... also front easy install (i know i need to buy dofferent bolts for the front). Thanks

Fitment is 100% OEM with no issues besides on rear rotors you just don't use that small bolt that holds the rotor in place. You don't really need it - it's just used to hold rotor during installation and to make it easier.

The green arrow shows that our hub and f85 rotor for rear - holes don't line up for that bolt. No big deal.

Thanks! Should i order different screws/bolts for the rear if i install f85 in the rear. Have m performance brakes rotors front and rear (non f85 rotors for now) thanks!
