Rear Disk Rotor

G`Day all. Am new to community and finding it a wealth of information-thanks. Have just purchased a K1200LT having owned previously 3 x K1100LT`s.Would have brought another but could not find good low mileage ship. Purchased "Evangeline" from bikepoint-one of Barrys unsellables I think. 2002,black & chrome, G.P.S.,6 stack,cruise,two helmets with intercom,4,667Km on the clock for $16,500. There are some bargains out there! One problem. Have metal on metal noise coming from rear(the bikes!). Have been informed this is rear disc rotor and was subject to a recall. Does anyone know anything about this? Sorry for sparcity of info but I am not mechanically minded, in fact my wife developes chest pain if I as much as pick up a hammer!! Would appreciate feedback, Regards, Swampy.

Re: Rear Disk Rotor

Hi Swampy, welcome to the mad-house

Metal on metal sounds like it might be brake pads about gone? Is there any scoring on the rotor? Check for that.
The rotor also has some "play" in it, which can sound a bit like a "cow-bell" sometimes. That's not unusual.
I have had a rotor replaced (under warranty) for excessive play after my rear brakes wore very quickly (down to metal) and damaged the rotor.

Checking the rear pads is pretty easy (I've managed to do it )....
check on the FAQ the instructions might have been posted there. If not I've got a Clymers manual, I could scan a couple of relevant pages and email to you.

Cootamundra eh... you'll be a prime candidate for our next Snowy Ride meet!
Welcome and enjoy the site and the group.
cheers

ps.. check the "Similar threads" at the bottom of the page... sometimes you'll find answers there easily.

Re: Rear Disk Rotor

a lot of folks complaining about the rear brakes squealing. Some tried new pads, Some used brake quiet sealant, A couple even used carboard from a cereal box between the pads and the brake pistons. I came across some very thin phonolic sheet and used it instead of carboard. The only cure that worked 100% of the time was to turn up the stereo. You shouldn't have metal against metal unless your pads are worn out. Good luck and welcome to our community.

Re: Rear Disk Rotor

at 4600k wouldnt think they are worn out unless the pistons are siezed and holding the pads on, its more like rust from lack of use,
at 30k I had to put on a new rotor to stop the cow bell clanging, I used an ebc rotor it uses a slightly different floating system and hopefully wont fail again looking good sofar 70k now and not a hint of trouble.
yes there was a recall I had my 2002 done, in 2002 you would need to contact BMW to confirm if it has been done on your LT and if your lt qualified for the recall..

Re: Rear Disk Rotor

Thank you for the info. Bike has missed the recall and with so few kilometers on it will be interesting to see if BMW will fix it under warranty. Off to Rolfe Classic for a service and we will see what transpires. Am impressed with the bikes handling. Was initially put off by the size and weight in comparison to my old K1100LT but have found this a non-issue. I do 330 Km travelling to work from Cootamundra to Moruya taking in the Clyde on a weekly basis and very much enjoy the trip. I reckon I am one of the few people who enjoy going to work as much as going home! (Roos and wombats excepted!).

Re: Rear Disk Rotor

Re: Rear Disk Rotor

Yes just another poor design feature of the LT: next to the clutch slave cylinder which will piss oil all over your clutch plates soon (in view of the non use the bike has had all your seals will be hard) probably the engine will also leak rear main and others, gear box too. ) get the mod for the slave done soon and you will avoid a couple of thousand unnessasary expence) the rear bevel drive may get you to 20-30 thousand Ks. The rear brake disc has 10 rivets only 7 of which are able to carry the disc load as the cut outs for the other three are too big and don't even touch the rivets ( hell knows why. BMW dont!) . But I love the bike in spite of these things. but some things are piss poor!

Re: Rear Disk Rotor

Hi swamppy,

I had a similar problem at about the same k's, it was found to be loose rivets on the rear disc and was swapped out under warranty. I now have over 40,000 k's and haven't had any noise since. With such low k's BMW should come to the party, but may also claim it is from underuse.
