5000km and they need replacement........WTF?

I drive from PTA to Centurion 80% of the Km on Highway.

How many k's did you get on rear brake pads

BikerJan · « **Reply #1 on:** January 20, 2014, 10:32:29 am »

I had 6 500 K's on mine when I traded it, was not a problem yet

HermanH · « **Reply #2 on:** January 20, 2014, 10:33:48 am »

I've got 12,500km and they still don't need replacement

@6300km (~3900miles) mine are "gone"
just a fraction and it will be metal to metal
I never use the rear brake... (the bike does itself so why should I...)

Contacted my dealer and they are unaware about brakepads being replaced under waranty (Belgium)

Can some of you please provide me details regarding the waranty replacement? (could help me to discuss the issue with my dealer)
(I don't think brakepads "should" be gone after that distance...)

Anyway, i'll have my pads replaced today!
(waranty discussions are to be taken care off later)
I have no exact details, but my dealer made me sign a paper for it and they sent it to BMW.

There was an issue with some rear pads from the earlier K50 batches but that changed from mid year 2013 already. If your bike was manufactured July onwards by my estimates it should be OK on rear brakes but I may be wrong.

The thread from advrider stopped talking about the wear on rear brakes last year already, I have been tracking it out of interest.

Problem on some early bikes
3 bikes on our tour of Germany with LC's had to have their rear pads replaced at around 4K
And at the time a discussion with the workshop doing the replacement confirmed that they had done quite a few bikes at very low kms

BennNevis, how much did you get on your LC locally?

around 7K

Its not only the earlier batches, SGBs went on 5000 km.

I have a theory on this, hear me out pls-:

The throttle mode adjusts the Abs and traction control function aswell.

Given that and the fact that you use the rear brake more aggresively on gravel, I would assume the germans made Enduro and Enduro pro mode brake harder at the rear, compared to rain, road and dynamic.

This will mean by riding in Enduro, will wear the rear pads quicker.

Will this be possible, or am I overthinking this?

I am waiting for my LC and will test it.

The brakes are not linked in Enduro Pro, if the rear woks harder it would be because you press harder.

Most brake issues reported was in Europe and the bikes were riding tar. BennNevis actually experienced this first hand during a tour on K50's in Europe.

The other challenge is to explain how some of us have done 10000km or more without need for replacement. My bike is only used for DS riding, no commuting and off tar is always in enduro pro.

BMW said that it was caused by my driving style, the colour of the disc was used to come to this conclusion.

Put your bike in EnduroPro, disable ABS and TRACTION control.

You will be able to slide the rear wheel on gravel by only pulling the front brake lever.

ABS is disabled, but combined braking distribution is not disabled.

My theory is that the combined braking is adjusted when you you select different modes.

My bike is still relatively new, but I will test this in months to come.

Combined braking is always enabled, Enduro Pro disables ABS on the rear brake if the rear brake pedal is used.

I've got a late 2013 model, with steering damper,etc. It had 3000 km on the odo when I got it from the dealer-is on 6000 km today. I've done about 1000 km in Enduro mode. Rear brake pads on the metal- disc scored. I anticipate an interesting discussion with the dealer tomorrow if the term "riding style" is used.

My brake pads and disc were replaced by Continental P.E. free of charge and they gave me a loan bike for the few days they were waiting for a disc. Good service from them. They could not find any technical reason for the premature wear. Disc was also blue from over heating, but to be expected seeing one pad was on the metal and the other had a few micron of friction material left.

I contacted BMW SA to determine the root cause of the problem as I do not want a re-occurance of the problem in 6 000 km. BMW SA they are not aware of the problem and have not been informed by BMW AG. Besides the WD posts I sent them extracts from US & UK forums where the problem is also experienced.
Anybody else experience the problem?

Trudie's 2014 LC is always in ROAD mode and she seldom if ever apply rear brake.

How will one know if there is a problem on wear (without looking obviously) while riding? Will there be a sound or smoke or any indication at all?
None of us are really thinking of the rear brakes when using the front.

All my boxers (Oilies) have never required rear pads before at least 30k km and this "less than 10k" talk worries me.

The only way to visually inspect without removing the calliper is from behind the bike while stationary. Mine seems OK so far at nearly 10000km.

My 2013 also had no issues up to 10000km when it was traded.

I have very little mechanical sympathy and find it surprising that I have not needed new pads yet.

Remember that the rear brake works even if not applied due to the duel braking system.

I have not checked my LC close enough yet, but the previous model had marks on the retaining pin showing wear on the pads. Sort of a 90%, 60% and 30% wear marker.
