After Market rear disk?R1200GS

[Bendy toy]

Sorry I can't answer your question..........but that's gotta be a world record thread revival!!!

Maybe, but others complain about too many new threads on the same subject. TBH, it's still a valid issue.

Replaced my rear pads a month and 1200 miles ago. Just arrived in the south of France and checked brakes because one was binding and the rears have worn out completely and the disk is badly scored. Because the original pads only lasted 8,000 miles I used EBC. When I replaced the original set they weren't completely worn out and the disk wasn't scored. Any ideas on a cause of this premature wear? Can't think BMW will want to know because I used EBC pads rather than their very costly genuine items that don't last.

Maybe the caliper is binding and just needs a set of new seals. Costs are under £20 from BMW. My rear caliper had to be rebuilt at about 6 years old and 40K miles. I personally dislike the linked brakes which seem to do very little other than wear out the back brake.

The fronts however cost £60 per caliper for seals AND pistons whether you need them or not. So its advisable to strip them early and with luck the seals should be re-usable.

I just got a 2007 1200GSA, it had just had a brand new (aftermarket) rear disc fitted prior to me buying it. It must be a common problem, I'll try and see if there's any brand markings on it.

Tapatalked from my MotoX Dev Edition.

Just had new rear pads at 12,000m, disc is ok though. It does seem odd that the rear pads wear quicker than the front, and odder still that soft pads wear the disc quicker. Though I do seem to recall that grinding wheels for use on hard materials are med softer so that new material is continually exposed.

Just to add my experiences to the mix: my mate has a 2010 twincam 1200 and mine is a 2011 twin cam. We ride together frequently and service our own bikes. We use the bikes for long trips abroad and neither use the bikes in winter. We get broadly the same mileage from our tyres and have similar riding styles. Last summer we serviced our bikes and found that at 13000 miles his rear brake disc was worn beyond the 4 mm wear limit: mine at 17000 miles was still in spec. The calipers on both bikes are clean and free moving and the brake pads show similar levels of wear - about 45 - 50% worn. We have no explanation for this anomaly. The only difference in the bikes is that I fitted Wilber's suspension to mine when the bike had covered just 60 miles. I'm probably 3 stone heavier than him and he's a short arse. As the yanks would say - go figure?

Motorworks, from £72 to £100 for a rear disc EBC or Brembo

Bits and bobs to service the rear calliper.

Just in case it is rider error, check the brake pedal flip up thingy. If it is down there is a possibility that the the rider can apply a little bit of pressure to the pedal without him knowing. However this is more likely to happen to someone new to the bike. Ignore this if it definitely is a sticky calliper. In which case the get out of trouble option is to thoroughly clean the thing and apply a little bit of lubricant and work the calliper in and out , feel for any binding in the slide. If the binding doesn't disappear then a field strip and repair or last option is a new sacrificial set of brake pads to get you home before you change the whole lot.

I don't know if the brake hose is flexible or braided on the early 1200's. If it is a rubber one then the hose may be past its best. This can cause it to trap the fluid preventing if from returning to the reservoir and keeping the brake pads in contact with the disk. There is just enough flex in the hose to do this. This, in my case, caused the disk to warp on the R1100S.

Doesn't list them for 07 or 09 bikes, Brembo or EBC. Anyone know how they are different? Guess they must be different if not listed.

06, 07 is the first R1200GS Adventure. 08, 09 is the MU model where a few bits and bobs where added and some things changed. 10 and onwards is the TU which is the twin cam motor.
