Red face rear brake opps!

I ran down one of my rear brake pads... I thought I had more millage left on them, I was wrong. The rotar doesn't seem to be terrible damage, only tiny dings and scraps left behind. This shouldn't cause much of a problem after a couple hundred miles. The good thing, the same day my new pads appeared in the mail.

Has anyone ran down their rear pads to the metal? Any possible problems with the rotars? BMW mechs mentioned the rotars are unturnable and need to be replaced if damaged.

I've never done that, but if the rotor isn't scored badly and it didn't warp from overheating, you can still use it. Take some fine emery cloth and sand down any rough areas on the disk, clean up with disc brake cleaner and reassemble with the new pads.

Curious, how many miles did you have on those pads? I am close to rolling 12k, and be honest I have not checked my pads yet personally. I know everyone has different styles, but wonder on the average what people are getting on pads.

On a K75, yes

I did it on the rear of my 1990 K75S. Actually the pad part separated from the base on the outside (left ) pad. It made a godawful noise, and scored the rotor in about 20 feet. I didn't turn the rotor, but did rub off some of the rougher edges of the scoring, with first a file, and then an emery stone. The new pads took care of the rest of it. I don't use the rear that much anyway (the pad went away at about 75,000 miles, and it was the one that came with the bike).

Andy,

The rear pads seem to wear MUCH faster than the front. I replaced my first set of rears at 13k and they were fully shot (not to the metal, but not far off). It's easy to check what you have left, simply remove the plastic dust cover and you can get a decent view of what's left.

To answer how many miles I had on these pads, about 12k, but I took a 7k cross country trip, which should count for much. My first couple sets ran down in about 6-8k miles. The rears wear down fast due to the integrated/servo braking system.

You might be about due, if you have the ABS III (aka EVO) on the bike. I get about 12k and the service folks say "Time for a change", plus I've heard that as a general concensus. Fronts...man, those are a different story. Still got pad left, and over 55k miles on the originals.
Then, too, I've got a Subaru Outback (easy folks...I'm one of the few renegade Subaru drivers. Don't lump me into the "They're almost Volvo drivers!" catagory) that got the rear pads changed at 80k. Manual transmission, and I'm a firm believer in engine braking. Front pads still have miles left on them...Just wish I could get the same tire mileage (93k miles) for the bike.

i bought my 98 RS with 6200 miles on it and the rear pads almost to the metal. New pads and at 17,000 miles i hit the rotor. it was scored and when I checked, it had over .060 run out. 297 bucks later I have a new rotor. and for 20 bucks more I have a clock. sheesh,, 17,000 miles and the 3rd set of pads.

jimmm - spot on! If you don't check the run out and scoring on a rotor, replacing pads is a waste of time to expect high mileage. At the mo. I reckon 8K on my '97 non ABS. For anybody else, only one rotor on the rear and very little friction material when new means lots of wear if you use the rears.

Heres' a tip I used on thicker cage pads: Drill a small hole on the edge of the pad and insert a fine ptfe insulated wire. There's your leadout for a pad wear warning device ( shorts to ground when worn). On these thin pads you might need to think about a groove sealed with a (very) high temp filler.
