Title: R1250RT brake fault
Post by: PeteM on 2019-04-22 12:10:22
Took my three week old 1250 in for it's first service last week. Front brake caliper is leaking, dealer not happy with me riding it. BMW have no stock of replacement calipers* and don't know when they will have stock. Dealer is doing everything it can to sort out the issue, I've got a courtesy bike from them on long term loan until mine is back but it is F750GS which is no good to carry a pillion with mobility problems, as my wife has.


Complained direct to BMW during the week, apparently there are a number of people with the same issue but they have no idea when it will be resolved, one of the senior customer service managers is dealing with it but he will not speak to me. They are going to try and get a more suitable load bike to the dealer for me next week but no guarantee and I have in the meant time not had a bike for a sunny long weekend.



You would have thought after the muck up when they introduced the 1200 LC that they would make sure everything was perfect this time round.


I am not a happy bunny. >:(


* I actually don't believe this, they will not have stopped the production line, they are just choosing to feed their stock to the line rather than disgruntled customers.

There have been a number of GS with the same issue. I was told that it was an issue with the calliper assembly and BMW have now sorted the problem on new build bikes, but not sure how true that is. Was yours a stock bike or was it built in the last couple of months? I knew about this and have been keeping an eye on my front callipers. Although its not as bad as the suspension mess up when the LC was launched.

It was built in early March I believe

Ok, when they started to have some issues with the GS early March and there was a bloke on the RT facebook group that had a leak as well they apparently changed some process in the calliper build. My bike was due to be built the 27th of March, but they delayed the build for a week. Not sure if the delay was due to the callipers issue though. But somebody on another forum said that Hayes shipped new callipers to the factory for the production line so that is probably why there is no dealer stock at the moment. But its not all bikes that have had issues, so its not a recall as yet. But as I said, I'm keeping a close eye on mine. Others have also said it only seems to be the right front that has a leak, but I'm not sure if that is correct. Hope you get sorted soon.

Hi, I am new to this forum and just got my RT 1250 3 wks ago. Took it for a long ride a couple of days ago and when I got back I noticed that the front right rim was full of black splatterings. The left side of the front rim also had black specks but not as many. I inspected the splatterings with my finger and it looked like damp brake dust. I then passed my finger beneath the caliper voids and my finger came back completely black. The dirt did not appear to smell of anything. I suspect that the splatterings are created by some sort of brake fluid leak, although I have not seen any physical leak.
Has anyone out there had this problem with their RT1250 and is it brake fluid leakage?? I'd hate it to be a leak but the bike is due for it's first service in 400km so if it is brake fluid leakage I can have the dealers to have a look.

My rear rim gets splattered with black gunge more than the front.  I'd assumed it was stuff coming off the brakes, as with the alloys on my car, as I can't see any sign of a leak (and rear is Brembo so presumably couldn't be same assembly problem?).

Haven't used my bike for 3 weeks as I've had some lower back issues. This morning I saw a few droplets of brake fluid on the front right rim of my bike. I also stuffed some cleaning paper into the calliper and there were brake fluid patches when it came out. Definitely brake fluid leak. Anybody else out there with this issue??

Thanks David, I have seen that thread and it seems that I am not the only one. Interestingly I mentioned the problem to my dealer some time ago and he told me that it was the first time he'd heard of it. I wonder what he'll say now. Don't know if it's safe to ride the bike or not.

Think your dealer is telling porkies. Most seem to have got the issue before the bike left the show room or it is found at 600 mile service. I have done 3k now and fingers crossed still have a dry calliper. My mates calliper was changed at the 600 mile service.

I wonder how many R1250RT's your dealer has sold on the Rock.

I've only done 585km on mine so I still have to do the 1000km 1st service but I emailed the stealer this morning and am waiting for a reply. No BMW Motorrad dealers on the Rock, I had to import it from Spain

Errrr...... No.  BMW have form for releasing less than fully-developed and tested products and letting the punter be the test mule to find any remaining issues.

I was in a BMW showroom 2weeks ago and noticed a spot of fluid on the floor by the front wheel of a brand new 1250 RT, felt under the L/H calliper and it was wet with brake fluid. And that’s before it has even seen tarmac.
Doesn’t look like anything has been resolved yet.

Not all bikes have the issue, apparently its an assembly issue, so maybe at the pdf stage. So easiest to just fix the ones that have an issue, if they did a recall for all bikes, people would winge that they had to take their bike for inspection for no reason. There is only a small number that are impacted, RT and GS/GSAs so I guess their approach makes sense.


Bad to have one sitting in a showroom with a leaking calliper, would have thought the dealership would have sorted that pronto.

Went to my dealer yesterday and they have placed an order for a new brake calliper. They didn't argue much when they saw the state of the wheel, although the calliper in itself was all dry. Seems I am in luck. The part should be available on September 7th so I will see how it goes.

I wouldn't say you are 'in luck'. It shouldn't have leaked and the BMW dealer is just doing their job.

Just had the faulty calliper replaced by my dealer. Guess what, the calliper is not leaking any brake fluid but the puffs of brake dust over my front right rim are happening all over again. Has anybody out there got the same problem or knows what the problem could be due to ?? Starting to get on my nerves this thing is.


I have had my fair share of bikes but I have never had this occur to me before. I would appreciate some feedback before going back to the dealers.

Thanks Casbar, I have also checked other RT 1250's and the wheel rims do not show the puffs of brake dust that my wheel shows.

Hi Bandytales,


I haven't got a smart phone to be able to take a picture and post it. It's a bit difficult to explain but if you can visualise loads of small elongated puffs of black dust, interspersed all along the circumference of the wheel rim, you have it spot on. To be fair, the replacement calliper does not leak brake fluid, like the original did, but the puffs of brake dust are there all the same. If I manage to get my hands on a smart phone I will try and post a picture.

Yep, I get the brake dust on mine, but there's no sign of fluid leak. I didn't perceive it as a problem apart from cleaning :D

I have about 7500 kms on mine and have noticed more black brake dust than I ever experienced on my previous ride, a 2012 R1200GS with Brembos on the front. I haven't noticed any fluid leakage.
Title: Re: R1250RT brake fault
Post by: Douglas on 2019-10-08 16:36:12
Did about 300km last weekend. Got to cleaning the brake dust off the front wheel and also dabbed the insides of the "new" front calliper with a small piece of toilet paper. To my surprise I could see small brown stains of brake fluid mixed with the black of the brake dust. I am back to square one as I suspect that the "new" brake calliper is also leaking brake fluid. I will use it a bit more to see if this carries on and if it does, it's back to the dealers.

Well he doesn't seem to concerned about it. I wouldn't say its a common fault, think on UKGSER there have been about 8 people with issues and on here possibly the same, so not sure what proportion have the issue. Mine has been fine and my local dealer hasn't seen any or hadn't a month ago.

My dealer had two or three other bikes in at the same time as mine.

Maybe so, but out of the total of GS, GSA and RTs sold wonder how many had issues. I know at least 10 people with new bikes that haven't had any issues at all.

!Why would you even consider dismantling your calipers when the bike is brand new and under warranty! Surely if this concerns you, you should be beating your way to your dealer's door?

Hi Bandytales,


The reason being that my dealer has already changed the calliper and the problem persists. I would like to know if the calliper pistons are leaking brake fluid, which means that BMW is not only installing faulty brake callipers from factory but is also supplying faulty brake callipers as replacements.

So why not take the bike back to them with the dirty marks?

That is a bit of a leap thinking they are fitting faulty replacement callipers, nobody else who have had the callipers replaced have had the same problem again. What does brake dust have to do with leaking callipers. If the callipers are leaking, you will see the fluid, its wet. Brake dust doesn't come from leaking callipers.

That's the thing, I checked the interior of the replacement calliper with tissue paper (which is very absorbant) and it came out with brown brake fluid stains mixed with black brake dust. Seems to me that there must be some sort of leakage inside the calliper.

I would take it back to your dealers then, but if you do take the calliper off, take some pics if there is a leak. Like I said, I have seen no reports on any other forum or facebook of a replacement calliper leaking on any GS GSA or RTs, so this is potentially very worrying for those that have had replacements.

Took bike to dealer on Monday as both front callipers are leaking fluid. Called them up today and their reply was that they are waiting for a reply from the technical department :eek: . I am putting pressure on them to release the bike back to me, as the bike is rideable (it's just a matter of cleaning the rims after use) but they want to keep it until they receive an answer. They claim safety issues are at stake. Let's hope this saga gets sorted soon, we are having really good biking weather round here.

[size=0px]No, I haven't asked them for a courtesy bike yet.  They say they are waiting for the technical department to give them a reply. Will go to the dealers on Monday and have a nice civilised chat with them. Don't see why I cannot have my bike back if they have done all the tests on the bike and they are just waiting for a reply from the technical department. Will update on Monday.[/size]

Maybe they're concerned that the technical report could come back saying this is a safety issue as the brakes may catastrophically fail.  They then wouldn't look very clever if they had allowed you to carry on riding.
Unlikely, I know, but ......
I would always ask for a courtesy bike as a matter of principle (and I like riding other bikes  ;D )

Hi Gogs01. Got my bike back from the dealer yesterday. Nothings been done to it except that they accept they have to change both front callipers. Apparently there are only left hand (Modified) callipers in stock and the right hand ones will not be available until the end of December or early January 2020 :not: . No point in having the bike at the dealers. In the meantime I will carry on using my bike and keep an eye on the brake fluid leakage, making sure that it doesn't get any worse. To be honest the leakage is so small that it is hardly noticeable. The brakes work perfectly and it is just a matter of having to clean the wheel rims with water, every time I go on a ride.

Post by: gogs01 on 2019-11-13 23:57:28
OK, thanks for the update.   :)
It does still feel odd, that you could potentially set off on a multi-thousand mile trip with a bike sufficiently "faulty" that both front brake calipers are going to be replaced as soon as replacements are available.
I'm guessing that you won't be doing many miles and it isn't therefore going to be a serious issue, but my default position in cases such as this would be to ask for a replacement bike. This keeps you "safe" and would tend to speed up the replacement process.
However, it is of course your call and you will be able to spend time polishing and admiring your beautiful machine.   :thumbs:
