Ceramic Front Brake Pads for F85 X5M ?

[dslaughter_F85]

Perhaps this is a noob question, but if I'm installing the Powerstop pads, do I need to order 4 of the sensors, one for each wheel?

Thanks.

Only two..one front & one rear,

[Yuille36]

You only have a total of two sensors on the vehicle, drivers front and passenger rear, if I'm not mistaken. It's possible that you might not need to replace the sensors, if you had a recently replaced your pads, as your sensors are probably still good. But, personally I would change them as their cheap.

I just installed my Powerstop pads. I live not hearing the squeal, but damn, the performance degradation is very noticeable. Feels like I’m braking in a Honda Passport.

You might want to wait until they fully bed in and transfer material to the rotor. The only thing I've noticed is repeated stops from very high speed where they got too hot.

How are the Powerstop pads in regards to how linear the braking is?

I think my M has stock and they are not linear, meaning that when I'm coming to a full stop, when slowing down to roughly 10mph, they start to grab like crazy. I have to really feather the peddle so that it's a nice linear comfortable stop. Otherwise, if I keep the same amount of pressure on the peddle, I'll stop too soon.

[ekological]

It's tough to talk about that. Yes, it's there, but I think it was present with the original stock pads too. That has to do with the idiotic transmission programming and maybe the brake by wire algorithm as well. Certainly not the smooth braking I can do in the '02 m5, '99 m3, '11 m3, '05 elise, etc. I have 50+ track days under the belt, drive hard, and still have the previously listed cars in addition to an exotic and am sensitive to these things, so it's not like I'm some guy who puts around, doesn't come close to the limits and then talks out of his ass.

After the last covered service where they changed out the rotors and pads, the squeal went away and did not return in almost 10k miles before I swapped out to powerstops, so the squeal wasn't bothering me. What did bother me was the dust. After washing and cleaning the wheels, you could see the dusting on them after a few trips.

My assessment is that they are good enough and it's great not to see dirty wheels a few days after washing the car! I did find the limit where repeated stops from high speed induced fade, but I'm not planning on tracking this SAV. I have confidence that mashing the brakes will haul the car down without problem for that occasional blast of speed.

So whats the option for people that dont care about the brake dust, but do care about the noise?

Priority would be:

1. Initial Bite/ sustained/ Stopping = Minimum OEM level
2. Noise = Less than OEM.
3. Brake Dust = 0 Fs given.

Yuille36 appears to have the greatest experience with pad choices, research etc, I'm still on oem for fear of loosing the feel, that's the main sacrifice from what I gather. Hate the squeal but love the feel

[ihavesoldout]

To answer your question

Stopping power = 10/10 same as oem at full pedal travel
Initial bite = 8.5/10. Similar as oem after bed in. Can’t tell the difference now between the two.
Noise = 10/10 better than oem zero noise at all
Dust = 8/10 way better than oem but not completely “dustless”

[Yuille36]

Although, I agree with your assessment, I might add that dust is about 9/10 with Power Stop Carbon Ceramic Pads. Once that pads are fully bedded in, I'd be surprised if you can tell the difference between ceramics and OEM

[ekological]

Did you change to new rotors when you swapped pads? I didn't and even though I hosed the rotor holes from the side and tons of stock pad dust came out, there was a lot more inside. Also, did you clean the calipers completely? I was lazy the first time around and didn't and I found that a lot of stuff came out on the bedding in process...that could definitely not have come from the powerstop pads for those short stopping bursts.

I did change out my rotors when I swapped out my pads. I used a toothbrush and brake cleaner to scrub all the brake dust from inside the rotors. If you want the best results, you must use a little elbow grease, and do it right the first time.

[ekological]

My question wasn't directed to you. I swapped out the pads without a deep clean because I was fearful of some people saying the bite wasn't there. If they were awful, I was going to rip them out ASAP.

Sorry….🥲

[Chilled]

Yuille36 , have you tried applying that stop squeal to OE pads?

Are there any aftermarket Rotors that stop the squealing? As in steel.

The answer is No, as I was swapping out for new rotors and ceramic pads. But, I don't know why it wouldn't work. You have to generously soak the liquid into the pad until it turns black, and let it sit for 10 minutes before reinstalling. But, my squeal only happen right at the very moment that you came to a complete stop. My issue was the excessive brake dust, and having to clean the wheels every three days. But, latter I learned that my issue was more related to cleaning with a strong wheel cleaner, that was causing more surface rust on my rotors, thereby exaggerating the squeak.

Now that, I have the carbon ceramics on, I wash the car every week instead of every few days and no squeaks.

When we removed the calipers, the pads showed rust on their surface. So I knew then where the squealing was coming from. It's been a months now, and no noise or squeals. And I have to tell you, that I love it. The liquid comes in a little white bottle, but looks white out. But applies like a big fat magic marker. When applied, it needs to setup from a 5 minutes to soak in, then reinstall. Good news a little web search, and I found it, it's BG Stop Squeal.

Has anyone attempted this product on the OEM brake pads?

[NYBulldog]

I bought Power Stop Z23-1738 and NXE-919B, what a game changer. The noise was ridiculous.

[jab23]

I've had my Powerstops for over a year now. I've obviously gotten used to them, but the most noticable thing at first is the lack of initial bite compared to OEM pads. I only notice it now when I get into a rental car and proceed to almost put everyone through the windshield on my first couple of stops! The other thing, and I didn't have my OEM pads on long enought to compare, but when I'm on the highway for a long stretch in rain or snow (especially snow) without braking, the intitial bite on the first brake attempt is a bit harrowing. Also used to this now and tap them now and again to clean off the rotors. This all sounds worse than it is. Day to day driving is perfect and the M stops hard when you need it to.

With all of that said, I wouldn't go back to OEM if you paid me. Sounded like a city bus when I got it and now haven't heard a single squeal in 16 months. Also cut brake dust by at least half, maybe more. Highly recommend.

[Slickrick2]

Hi guys, about to pull the trigger on the front and rear Z Stop Brakes. Can't deal with this damn bus squeal noise when breaking in slow traffic.

I'm a bit confused and hope someone can chime in. Some members say order two censors with the same part number PAGID 355251731

While others say use this one above and the second should be the PAGID 355251751

Can anyone please verify which one I need or do I need both and if so which one goes to the front and which one goes to the back?

I haven't purchase yet because of this.

Thanks.
