Dodgy rear discs

I'm currently punting around on a 05' 1200 GS, which I picked up earlier this year. I'm now onto a third rear brake disc, BMW at Caterham have replaced both under warranty, but have charged for labour, loan bike etc. Chisellers.

No other faults have been found, brake pads within tolerances etc.

Does anyone have any ideas, I had a previous 05' 1200 GS for 18 months & this didn't happen. Are BMW making discs out of blotting paper?

Next time I'll source the parts myself, recommended spares suppliers?

Thanks

The standard disks seem to be made of very soft metal. OEM organic compound pads eat them for breakfast.

I fitted a Galfer wavy rear disk with EBC HH sintered pads from nippy normans and it's lasting much longer.

I believe that the Servo ABS bikes apply a fair bit of effort on the rear pads whenever the brakes are used, I tried to adapt my style to use engine braking and anticipation to avoid using the brakes as much as possible.

my original disc lasted around 30k, but got to admit should have changed it around 25k as it was in pretty poor condition. the problem i had was uneven wear, one friend described it like a ploughed field. i went through a set of bmw pads about every 10k on that disc.
i now have a replacement disc from motorworks and use ferodo platinum pads and the wear rate is much more even and the pads are lasting a lot longer. i haven't noticed much difference in the braking to be honest.
hope this helps

I never had any problem with my rear pads or discs in 18000 kms before i sold the bike; this had a servo which i found very good - but no better than the latest brakes now without servo. I did change my style , having linked brakes, and gave up using the footbrake altogether. I wonder if there is a connection,

30000+ on mine and 50% wear on the pads, commuting into London every day

I suspect yours has linked servo's which seem to eat discs.

I still have the original frint discs on my 06GSA and have had the rear on for 30k. My bike has done 50,000 mile, is non servo or ABS and I do give front brake some hammer because I rarely use the rear.

They are still well within tolerance but will be changing them over the winter.

Try aftermarket discs next time. Steptoe does a good line in discs and they are definately better than the OEM ones

Thanks for the hints, my 1200 has non servo brakes if that makes any difference.

Ride fast, take risks, I always do. Sarge

Even without servo your brakes are linked and if you use the rear brake (pedal) a lot this mght account for the abnormal wear; however as you didn't have a similar problem on your previous bike there is still a mystery; Probably the best thing is to change pads and discs at the same time - and that may cure the problem; otherwise it could be bearings or disc 'run-out;' however that is only my opinion - surely your dealer should know;
