It triggers when the front, rear, or both sets of brake pads reach a certain thickness. A sensor is slotted into the brake pad, and when the pad wears down enough to expose the sensor to the rotor, that contact trips the sensor and turns the light on.Quote:

The pads are pretty much paper thin when it triggers
These are the 2 thinnest pads. Should these be replaced soon?

edit: Looked it up and it looks like it's time. Not sure if I should just replace these two or look for new brakes all around.
Just wait until you literally grind to a halt (it won't be long!), and throw new rotors, pads & sensors at it!Quote:

These were the fronts.

Also.... Be advised you're not looking at the inner pads.Quote:

Those pads look like they're at 50% or so... depending on your driving habits, they could last for quite a while
I'm thinking of going ceramic, so I would probably need to be consistent on all 4 corners. FCP has a Meyle/Akebono kit. Has anyone heard anything about Meyle rotors?
With all of the rotor choices available & the continued decrease in Meyle parts quality I would choose something else.Quote:

I had akebono ceramic pads on my e90 and was very happy with them. My main goal was to reduce or eliminate the brake dust, which they do. I don't track the car and my driving style is non-aggressive, BTW.
While I can't speak to Akebono, I can say that I do not recommend Hawk "Performance" Ceramic brake pads. I've had two sets in the time I've owned my car (once voluntary, the second time involuntarily) and for both of those time periods, I've had the same issue. The pads don't have very good bite/feel to them, and occasionally when it's raining out and you've been driving on the highway for a while without touching the brakes, there can be a very unnerving vague feeling after pushing the pedal down, giving you that "oh shit, I have no brakes" feeling until they dry off. It only takes one application of the brakes to dry them, but it also only takes one application of the brakes to realize you don't have the braking you expected and rear-end someone.
Otherwise, they're fine when it's dry, but the lack of overall feel is a bit disappointing.
That seems to be similar to some of the comments on the Akebono ceramics.
Do you have a DIY for this? To avoid intense orange peel?Quote:

I would say slotted before drilled. But if you're saying that because of what I said, I can't recommend the PFC-Z pad enough (bimmerworld only). Lot of modulation when cold, but one hard stop and it bites at the top for the rest of your life. The dust is comparable to OEM but its the pad that never gives up. I know I am in a 328 but I am running 330 brakes. Just my two cents on pads if you're in the market. I did a CCA drive and was hustling behind an 11 ZCP M3 and experienced no fade. It can start to squeal a bit after lots of aggressive stopping but it goes away when they cool back down.Quote:

My understanding, from everything I’ve seen, read, and heard, is drilled rotors are really about aesthetics, and slotted rotors are for performance (drilled discs crack). Admittedly that’s more about extreme-stress driving, but I’ve never been able to look past that fact.Quote:

Sure, they're 'better' because they improve braking power, but at the cost of increased heat. (There's also some benefit from slotted/drilled rotors because they remove any gas buildup between the rotor and pad when the pad material off-gasses at high temps.)
Best way to reduce brake fade: Bigger, thicker rotors (more mass) and cooling ducts. The performance benefit of drilled rotors is debatable, and if you buy a cheap product you're likely to experience cracking/failure. Porsche has been putting drilled rotors on their cars for decades... They serve more than one purpose, and I guarantee you the original intent was not for 'looks,' but they're a much higher quality product than all the crap that makes its way over here from China. :rolleyes
(ps: if you've ever seen F1 rotors (prior to the advent of carbon-ceramics) they have never used drilled or slotted rotors.)
I ran drilled Zimmermans on my previous car (Porsche fwiw) with no difficulty except that the holes would sometimes cause freezing/filling problems in winter. I wasn't driving the car on the track so fade wasn't something I had experience with. The biggest benefit I saw was in wet driving, and the improvement there was substantial. I never encountered cracking or warping. I think some members of the online group warned about warping, whether from direct experience or hearsay I can't recall.
Yay or Nay?

Personally I think they look good but I also think they look like are a rip off of the BBS red caps.

Yeah, I read that drilled rotors can help with the water issue.
Anyway, I ordered Zimmermann blanks and Stoptech Sport pads. Meanwhile, I'm taking it easy on my brakes.
I'm not really feeling those red ones. You want red vs the BMW std ones?Quote:

I can't seem to find any good pictures of those caps on a set of apex wheels. I'm leaning towards no, but if I actually saw a good photo of them it might change my mind.Quote:

I think I’ll stick with the bmw ones I have. Just thought il see what you guys thought...Quote:

Well, either way I will let you all know how it goes when I get the new brake setup on; hopefully this weekend. It will be zimmermann drilled, akebono ceramic and stoptech SS lines. Watch out for me on the brake thread:

I like, for example, the BBS red caps on a red car, but not if you don't have BBS wheels.
