E90 Discs and pads
Discussion
Your idrive on the service bit will tell you how many miles more they have left in them front and rear seperatly. If you don't have idrive it will be on your trip computer.
Only need changing them when it tells you - unless your sensors are faulty
I know using a micron measurement tool and visually checking pad thickness is the best way but you wouldn't check it that often. With idrive I tend to scroll through the service items once a month or so when stuck in traffic it's a good guide and gives ball park time and distance until changing is needed.

Ignore them. Garages are always making comments like that to line up some future work from you. I've yet to put a modern BMW through a service at an Indy without them saying it. this topic shouldnt take long.

I guess that if you don't have an itemised service schedule (i.e. Most cars) the assumption is going to be that the car won't be back to a garage for up to a year, so you always have to have a years worth of pad left.
Just do it when the iDrive tells you to.
you can source OEM parts from gsf or euro car parts easily enough. pagid or textar on the pads and sensors not sure about the discs. should be able to get the parts for less that half the quoted dealer price and its one of those jobs thats easy and satisfying.
if in doubt about the need to do it call the dealer and ask what they recommend as to min depth of disc and pad and then measure yours with a gauge. chances are pads ok if no light on dash but may as well do the whole lot if your discs need replacing

Can't help regarding E90, but my E46 is £255 for front discs and pads fitted from my local BMW dealer. However I do think this is an offer they are running currently.
I noticed the local dealer has special offers on discs and pads.Big banners all over the service area.
Which always makes me suspicious.
It raises two questions.
1/ Are they going to recommend replacement when it's not strictly required, as a cash cow?
2/ If BMW disc replacement is so common, what's wrong with them?

Without a doubt!! However I have measured mine and am in need of fronts, with rears not being too far behind. I would imagine if the car was in for something else without brake replacement being on the list of jobs, they would have warned me about my dangerously low brakes or some such nonsense.Thing is it depends on how good an offer it is
i.e. say a set of discs & pads have a useful life of 60k miles (assumption) and they cost say £600. Therefore every 5k miles in effect costs £50.
So say the offer is £400 for discs so IF the usual prce is £600 per 60k then the milage at which you could change them without being any different is 40000 MILES. As in if you bought one set for £600 and then changed them early and not worn out at 40k miles for a set at £400 and then run those for the full 60k miles then it will be an indifferent cost per mile.
So thats the breakeven point - if your anything above this or much closer to 60k then its a no brainer even if there are a few more k miles left in theset on the car.

Does anyone actually work like that, how do you know how long the cheaper ones will last? You really dont so its not really worth looking at. If you want some cheaper ones buy them, if you want the dear ones, well, just buy them.i.e. say a set of discs & pads have a useful life of 60k miles (assumption) and they cost say £600. Therefore every 5k miles in effect costs £50.

Honestly I do work like this - maybe Im a little sad....
I also consider how long Im planning on owning the car and if I know I'll need 2 sets of discs & pads in my ownership Id rather do an early change so I get more of the benefit over changing them just before we sell.

Im an accountant.
I do the same for tyres, discs & pads and also car ins as in cancel it part way through a term if a better deal is available.
I do very similar for everything with the idea that I can get the best brands or best quality food/drink/holidays/kitchen/bathroom etc at the best possible cost for myself.
I also do really through the money about stupidly on gifts holidays and nice things because of being sensible on the every day items.

I throw money at my cars and have great quality holidays, food and drinks too and dont worry about too much...
Anyway sorry about the drift on this thread..
Thanks for the feedback guys. wasnt expecting such a response. Ive got a pretty good idea now so cheers. The dash computer tells me its 7000 miles until i need to change the front pads, however, the technician said that the side with the sensor(apparently only one per end of car) has more wear left than the other so i should change early. That said, he recommended my discs changing as there is a substantial lip on them. So... i think im gonna just carry on until its obviously worn, like when computers in cars didnt exist?

How can you run an E9x where you have to think about saving for discs and pads? Am I the only one thinking this ?
Its a five year old car. I bought it four years ago. I earn less then i used to (thanks Labour government), and now yes I need to save. And nobody is gonna make me give up my beemer.Gassing Station | BMW General | Top of Page | What's New | My Stuff
