Re: Brake rotors - life expectancy

As a general rule of thumb, rotors will last through two sets of pads. Your mileage may vary.

Hi all,

Okay, I'm relatively new to BMW ownership but over the 3 or 4 months I've been listening in on this group I have read a number of posts concerning brake discs (rotors not pads) wearing out in 50/60k miles. Is this typical, or am I picking up on something that might not really be the norm? I'm talking BMW models generally, of course.

To put this in perspective, my daily use vehicle is a 1996 LR Discovery which has 150k+ miles on the clock and which I've owned from new. The rear rotors are the originals and the fronts have been replaced once (under warranty) due to hairline cracking. This vehicle spends quite a bit of it's time off-tarmac - typically 15 miles per day, 3 or 4 days a week - because of my job and the brakes are, therefore, subjected to much more abuse than a normal road car. During an off-tarmac foray the brakes are often covered/submerged in muddy gloop but despite this even the pads last 45/50k.

I understand that compared to the Discovery (even with it's 3.9litre V8 engine) just about any BMW is a "performance" car but the LR is over 2 tonnes so stopping from almost any speed in a hurry needs considerable braking power.

I'd appreciate any comments from the members of this group on this subject.
