Get SS rotor screws from ECS tuning.

Get silicone based brake grease. Silicone won't degrade the rubber boot over time. CRC makes the best. I think they call it Silaramic

If you really want to improve e pedal feel, get the Brass sleeves & SS pins from ECS tuning. You will have to re-grease the caliber pins once a year, if you go this route.

Simply to show the importance of using CORRECT procedures from a RELIABLE SOURCE (which "F30" is, because that is what HE has DONE -- XX Times ;-) I attach two links from TIS which he has referenced generally: (1) Removing & Installing Brake Pads & (2) Guideline for Applying Brake Pad Paste:

NOTE: 34 11 000 states:

Clean guide screws only; do not grease.
Check threads.
Replace all guide screws which are not in perfect condition.

While Video's and Forum DIY's MAY offer some additional insight for an inexperienced DIY endeavor, such as photos or concept explanations that were NOT offered in TIS or Bentley, I would suggest NOT relying on those for anything MORE than supplementation of TIS & Bentley (and folks with years of experience like "F30" ;-)

You will see a LOT of different statements and concepts expressed on the Web or in the Forums. It takes experience to learn which ones to follow and which ones to dismiss, so start with reliable sources, and question anyone who tries to tell you something different. Don't fall prey to "Believe ME"

Perfectly stated. The availability of newtis massively made BMW ownership easier. Back in the day (2006 LOL) when there was no Bentley service manual for the E90 and no newtis, one had to pay a $35 one-day fee to get on the real BMW TIS. I spent a day hoovering as many E90 procedures as I could since I was racking up 800+ miles a week on my car. Having 18+ years at the time wrenching on BMWs helped a lot too. Even the Bentley lacks in some areas IMO, but it's great on explaining the theory of a lot of systems in the E90. I've seen a few videos and boy are things done far differently than what you or I would do.

However, I deeply bow to you for your prowess on fault isolation and repair logic, especially on the electrical system. Your service to the Forum is immeasurable Sir.

Why BMW doesn't make the rotor screw out of 10.9 or 12.9 I'll never know.

Some engineer got a phat raise for saving them an additional 4 cents per car.

Having owned and personally maintained Jaguars since 1969, Lucas (Prince of Darkness) made it mandatory to be able to read circuit diagrams & do basic system testing. When I bought the E91 in 2017, and found TIS (newtis), I realized how essential it was to take the time to learn (1) what was in it, and (2) how to quickly find component or system info.

Although I have NOT had any issues with my E91 in 3 years of ownership (other than 2 or 3 occasions of random misfire in the first two weeks of ownership, due to .055" to .060" enlarged plug gaps, cured by a plug change), I have gotten a BimmerGeeks K+DCAN Cable, downloaded INPA/ BMW Standard Tools, and tried to learn all about proper BMW diagnostics. As you state, TIS is the KEY if you take the time to learn how to use it.

I have done that by reading posts on the Forums, reviewing the applicable TIS circuit diagrams, and trying to figure out possible causes of the issue based upon how I perceive the schematic(s) to show a particular system works. Some engineering background helps, but it's actually something that ANYONE with a logical and enquiring mind can do with the help of TIS, IF he has the time to do it.

Anyone who has NOT tried it, just enter the last 7 characters of your vehicle's VIN in the following home page (change the language from "en" (English) to your primary language, Bookmark or save URL of resulting page, and learn what's there, at least for YOUR specific vehicle.

For those who don't realize all the FREE DIY support that exists for E9x owners, attached is a pdf of "E9x References." Please suggest any helpful sites known to you which are NOT included. If you know of a REALLY good site for SIB search, please advise. I have NOT updated this in nearly a year, so some links may be outdated -- please advise. One such is VIN Decoder. Instead, use:

Nice!

Only online parts seller I’d add is www.oembimmerparts.com. As promised, they carry the best (Oe manufacturer) at the best cost.

And yikes about the old jags - I’ve seen the Shim’s they used on the bodywork. Hard to imagine their electrical systems!

[mainbearing]

I use pliers to pull them out, and again to pull new ones through. The rubber is resilient. No grease used per instructions but you can use some silicone based grease to pull new ones through.

Cleaning the pins well is probably more important, because the pins become exposed and start to pick up dust as the pads wear. The new sleeves do feel more pliable, so I change them.

I'll give it a go if I find some that aren't in good condition.
