service due light (front brakes)

I got the "service due" light message and it was about the front brakes. I looked at the pads and they still have about 3-4 mm (1/8 or a bit more) of thickness. I am wondering if this is a 'preventive' call (the car has 44500 km on it) or this is the brake pad sensor triggered. What I am saying is - do I rush and get the parts now or there is still time to do it in the next 1000 km? Or I simply reset the service due and wait for the sensor to tell me it is time?

You can not reset at this point. It will error out.
Given pad material left, itís not urgent, assuming what you gave was max thickness and you donít plan on deferring the repair too far out. 1,000km seems more than reasonable.

Did you also check the inner pad? It usually wears faster.

Sparks when breaking is another good cue.

FredoinSF and deroy are correct. The warning is not urgent. You have time. The inner pads wear faster and thatís wear the sensor is. Do your research on rotors and pads. The sensor will need replacing as well.

yes, this is why I was wondering why can't I reset the service due using the car menu.. I was about to run ISTA to find out which service it is asking for. then realized I can see this in the vehicle data menu..
of course I did not check the inner pads but so far there was no noise coming. I am planning to purchase these for all 4 wheels - the rears are not much better than fronts at the moment:

zimmerman rotors, Akebono Euro pads or EBC (RED?) and OE BMW pad sensors

The sensor does wear out at around 4mm left of material. If all the pads are evenly worn, you are in no rush to change them, but ordering them is a good idea.

I go through the front brakes much quicker than the rears. Donít forget to use loctite, brake paste in the right spots, and clean everywhere with a brush.

You probably don't need to replace the rotors if this is the first pad change. The minimum recommended thickness is 28.4mm or 34.4mm depending on which brakes you have. BMW doesn't recommend thread locker, but the caliper screws should be replaced if removed.

Yes the bolts. I believe the bolts are single use unless you use loctite. You donít need much. Canít hurt. The $1.99 blue loctite from FCPEuro gives just enough for the job.

I do not think the caliper bracket to knuckle bolts need to be replaced. Nor do they come coated with loctite. I don't see anything in newtis about replace. Also, is is not noted in Realoem. Having said that, I bought a BMW Value Line Kit for my rear wheel bearings a month ago and it came with new caliper bracket bolts. Not sure why, but these are big bolts and torqued to 110Nm. These are not TTY bolts and not aluminum bolts. I didn't use the new bolts.

For non-speciality loctitie, Blue is generally for someting you intend to remove later and
Red is generally a generally for a more permanent.

Yeah those 110nm bolts take some good strength to tighten up.

It is in newTIS. Check the tightening torque table. I replaced them, why not. Kept the old ones as spares.

Strictly, for just pads you only need to loosen the sliding guiding pins. But that requires a long 9mm (!) hex bit which most dont have.

@gsnake2000 just to make sure it was clear, the bolts that need to be replaced are #3 in this diagram. The guide screws #6 can be reused after cleaning. Bolts #3 usually don't need to be removed to change pads/rotors.

Can you paste the newtis link that says replace them? For my two cars I don't see it.

Micro-encapsulated means they have thread locker on them from the factory. This is why they want you to replace them. 110 nm is also near the limit they state for M12x1.5 10.9 screws.


P.S. Checking the specs for the X5 that OP was talking about, it actually says renew screws (clean), not replace.

English is not my first language, but renew and replace are the same to me. If they meant ďcleanĒ they would have written ďcleanĒ, wonít they?

Renew can mean both.
Quote:
1 : to make like new : restore to freshness, vigor, or perfection as we renew our strength in sleep
6 : replace, replenish renew water in a tank
I'm sure you know the German stereotypes... Why use 2 different words to mean the same thing?
Also, sometimes there's both renew and replace on the same page.

Hmmm...not sure how I missed that

Even so, I have a really hard time with this one. Never ever had to replace these bolts on any car I ever had before. The self-locking type, those I think are the Torx head ones, I sort of understand. You end up deforming the cupped washer which provide the self locking function. My 2006 E60 came with hex head bolts. On my wife's 2009 E70, it came with the Torx head bolts.

I've had the carrier bolts off a few times on each of the cars. Always used a torque wrench to reinstall. Never was loose when I went to take them off the next time.

But, given this, I'd put some loctite on the hex head bolts and reuse them and replace the Torix head with captive washer bolts.
