...and no where did I suggest that the ABS applied the breaks. From what
the mechanic I was talking to told me the ABS wasn't letting the break
pressure release in one of the calipers after the breaks had been applied.
That's considerably different than applying pressure.
Unless someone drove it really hard (brake hard) or took it to the track, it
seems very strange that the discs would need replacing already. I have a
530i which is probably somewhat heavier than your 330ci, and I got new discs
after 44k miles (5 years). They were still usable though, but the would not
last through another set of pads, so I went ahead and got them done at that
Like others suggested, go to another shop for a second opinion or have the
disc thickness measured.
You'll see little surface rust as quickly as an hour after you wash the car.
That is not a reason to replace the discs. That's normal and will go away
as soon as you apply brakes.
It sounds like they want to replace them because they are corroded. Not
because they are worn, cracked, etc.
So, do you experience brake judder, any abnormal braking, etc? If not, I
would personally leave them on there.
Just say NO. You'd have to live on top of a mountain to wear the brakes out
in this mileage.
Perhaps they could explain further why they feel the discs need replacing.
Light surface corrosion does not accelerate disc wear.
From the gist of the posts, sound like you are located in the UK. I recall
from my tour of duty in the East Anglia area in the 80s that things corroded
quite quickly because of the salt on the roads and the wet climate. Here in
the US in the southeast where the climate is mild brakes last a very long
time -- 50-70k miles before new pads and frequently the rotors are still OK.
Unless you can hose the undercarriage of the car off frequently, or drive
more often, I am afraid you are going to be stuck with more brake problems
over the life of the car.
I'm originally from the NE coast of Scotland where besides the salt from
the sea we get vast amounts used on the roads in the winter - far more so
than the relatively mild East Anglia. And it makes little if any
difference to the life of discs. Other metal parts like brake pipes etc it
50k pad life suggests *very* gentle use. I consider 25k good - and I'm not
a hard driver, although do now live in an area with heavy traffic.
BTW the OP is unlikely to be from the UK - he mentions kilometres. ;-)
