roundy Posted March 29, 2011 Share Posted March 29, 2011 Can't take credit for this one, Neil "GS Shop" Harrison told me... Clean the brake debris and crap from the vent holes in your discs, it acts like a rubbing compound against the pads. Just cleaned mine out with a drill bit by hand, they were all plugged solid with nasty crap! Link to comment
CoarsegoldKid Posted March 29, 2011 Share Posted March 29, 2011 I replaced mine at 70K miles and they were still within spec. This without dusting them off. They get washed occasionally. Link to comment
JayW Posted March 29, 2011 Share Posted March 29, 2011 Hmmm. My disc holes don't have any crud in them, but why would this not apply to the front brake components as well? Jay Link to comment
CoarsegoldKid Posted March 29, 2011 Share Posted March 29, 2011 Pads....not discs... washed discs...70K miles on pads Link to comment
roundy Posted March 29, 2011 Author Share Posted March 29, 2011 The brake debris gets blown away from the discs up front... 70K miles on the same pads - OMG!!! wow... Most of my riding is commuting so a lot of rear brake action hence more crap... Link to comment
Dan5620 Posted March 29, 2011 Share Posted March 29, 2011 Pads....not discs... You said discs initially, make up your mind. As a side note, this is true about most holes. Link to comment

DaveTheAffable Posted March 30, 2011 Share Posted March 30, 2011 I must confess. I've occasionally had trouble with plugged holes. Link to comment

Post tittle - extend the life of your PADS jist of the text - keep your DISCS free of dirt Makes sense to me, no need to make my mind up?!?! Link to comment
Davey Posted March 30, 2011 Share Posted March 30, 2011 85,000 miles on original pads both front and rear; front ones will need changed in the near future but rear looks barely used since I rarely use the rear brake. Link to comment
Paul Mihalka Posted March 30, 2011 Share Posted March 30, 2011 Starting with the R1150 bikes if they have ABS they have front to rear linking. When I switched from the R1100RT to my R1150R with ABS my rear brake wear went way up. That tells me that I, and probably many others, was overusing the front brake and not using enough the rear brake. Link to comment
Peter Parts Posted March 31, 2011 Share Posted March 31, 2011 Sounds like a myth to me: the pads sweep the protruding debris out of the way and that hardly seems a source of wear. Big wear factor is that the one-sided spring-positioned caliper gets sticky and the far-side pad wears much faster. Always seemed a dumb/cheap design on BMWs part although there isn't a lot of room for a dual piston caliper. So, once in a while, give the caliper a shove to see if it is moving freely. Like clutches, some folks wear 'em faster. But unlike clutches, not a matter of good versus bad riding technique. Unlike cars, piece of cake and not expensive to replace bike pads - so I tend to use them harder than I do in a car. Ben great riding weather in Toronto, 42F degrees. Link to comment
Peter Parts Posted March 31, 2011 Share Posted March 31, 2011 .... brings me to engine braking which, for cars, is touted as smart eco driving. But on our bikes, downshifting and adding wear to clutches is a lot less sensible than using brakes hard. Ben Link to comment

Ben You've changed the subject a bit, but since you brought it up, I would argue that proper downshifting, ie matching revs as the clutch lever is released, does not appreciably wear the clutch. A discussion for another thread perhaps. Jay Link to comment

A discussion for another thread perhaps. Jay Respectfully, engine braking has a whole lot to do with rear brake pad wear. Unless you are used to wet-clutch styles, the BMW clutch can last a very long time, as you imply. But I can't say as my downshifting (for more engine braking) is anything remotely as smooth as my upshifting or the skill you must possess. And I'd sooner do 10 brake pad replacements (350,000 miles??) than one clutch replacement. Ben Link to comment
