Uneven wear on rear brake pads

[Tusky]

Just done 10k on the (2009) R1200GS and checked the rear brake pads as I saw a small score in the disc...

One pad has 4mm left on it and the other was under 1mm and there is a hole in the pad where I presume that the fixing adhesive has fallen out and this is where the slight scoring of the disc had been caused.

The front pads have 4-5mm left on them and I am a bit surprised that the defective pad was not spotted at its last service (6k)

Phoned up Coopers in Tunbridge Wells and paid £55.00 for new rear pads which I thought was a bit pricey then looked on ebay and saw Gold at £16.00 for rears and full sets front and rear for £36.00

Still sticking with the OEM ones as I am unsure of pads for pre 2008 GS's which have identical looking pads but I think that the disc is not fully swept by the pad and I would rather be safe than sorry.

Any thoughts or peals of wisdom?

Backs tend to wear fast - can't recall changing the fronts.

After last but one MOT, fitted an EBC disc and pads .....which I must check...

?

The hole is designed to appear when the pads have reached their limit. If you can see the disc through the hole in the pad material it's time for a change of pads.
Beware of buying the generic pad that fits the rear of BMW bikes, they have the same thickness of friction material on both sides, the pad for the bmw has to have a thicker frictionj material on one side so they reach the end of their life at the same time.

PS - The [URL="http://gsshop.co.uk/"]GS Shop[/URL] does pads and discs for the 1200 models

The original BMW pads have the BMW part number and BMW logo embossed onto the back plate, whereas the identical fit Brembo part (and any other brand of aftermarket pad does not.)

Your bike is a 2009 model and is therefore under the remainder of the two-year manufacturers warranty. I hope you are aware that using non-BMW parts will invalidate this. Personally whilst it is still under warranty I would buy a genuine set of BMW pads from my dealer and fit them myself, being sure to check the rear brake caliper for a clean piston and free sliding caliper action.

Sorry but theres no way in the world that I'm paying out £55 for BMW to have their logo on the brake pads.

When mine get to 3/4 worn I shall try out the EBCs that I've always used in teh past.

I may swap back to the part worn BMW ones every 6000 miles though, just to see how they compare

Like your thinking !!!

Yes hurts like hell but I will stick with new OEM ones on this occasion and need to research the post 2008 difference..... all the ebay ones are pre-2008 buy the look of it.

Thanks for all the input so far guys... all useful stuff

Brings up the interesting question of extended warranties, does anyone know if the BMW OEM rule applies to these ?

And watch your discs wear out twice as fast

And watch your discs wear out twice as fast

that's why i don't supply or fit ebc pads

 

[ducatiparts.110mb]

How many miles do you get out of a set of discs?

Over the past 20 years & 250k miles I regularly get 8-10k out of a set of pads and 22k out of a set of front discs. I don't regard this as particularly heavy wear.

 

[JohnnyBoxer]

22k out of a set of front discs

I don't regard this as particularly heavy wear

Rather you than me....................

20-24k for a set of rear pads

36-40k for a set of front pads

Never replaced a disc yet

All on a 1150 Boxer GS


As for EBC pads................never in a million years on a bike of mine................I've even taken new EBC pads out of RT's/GS's I've bought secondhand and
thrown them in the workshop bin

 

[ducatiparts.110mb]

36-40k for a set of front pads???

Blimey. Do you not use them then?

I've even taken new EBC pads out of RT's/GS's I've bought secondhand and
thrown them in the workshop bin - mind if I send you a reply paid jiffy bag?

Sorry already chucked out

Using brakes.......................not unless necessary...........with the engine braking of a 1150/1100 Boxer engine, they're a bit surplus

 

[Kremmen]

+1....exactly the same on the 1200.
If the road ahead is being read & correct spacing between vehicles is maintained, the engine braking alone easily takes care for a lot of the braking.

Agreed in principle but it doesn't work that way 2 up, fully luggaged and needing to get a shift on, when coming down the Alpine Passes........

17 days and over 1000 hairpins take its toll

 

[ducatiparts.110mb]

I think it depends on the roads and your level of urgency.

The motorway at 80 isn't going to tax the brakes. Averaging 50 on my road to work will.

I use the engine braking when its appropriate, but I enjoy the bike too and I don't see a problem in using up the brakes if I'm enjoying the bike.

Not on consumables like pads.

I'd be buying a set of Steptoe's finest which are really good and check the piston and caliper are nice and clean and the caliper slides easily.

I'm on my 3rd set of rear pads (second disc and pads fitted in May) and 3rd set of front pads on 61,000 miles and I'm heavy on teh front brakes. Don't have ABS or those horrible linked things!!!

The last set of pads still had a good amount of life in them but I changed them for a big trip as a precaution.

 

[Tusky]

Got the OEM pads..... Brembo TTH38GF (Complete with a slip of paper warning in BIG WRITTING, that only sinter pads should be used with BMW integral ABS)

Must admit I never new about viewing the hole to know when the pads needed changing, so big thanks to Steptoe for telling me that....

So.... next time I want to replace them do Mr Steptoe's finest match these as I am unsure when looking at the website?

 

[BlueBird]

the 55quid bmw pads are the sintered pads for the adventure, the ordinary bmw pads are bout 25 quid.

The sintered ones can take more abuse and last twice as long.

 

[Sgt Bilco]

.............and feck up your discs so I'm told. I use Steptoe's and get a minumum of 25k on the front which is brilliant considering the abuse I give the old girl

I only use sintered on the rear,I got 35k out of the origanal rear disc with sintered pads,on an EBC one now for the last 20k and its ok.

I run Steptoe front replacement discs and pads and they are great, because my origanal fronts were warped for so long I was favouring the rear brake and eating pads,now I use the front properly and my front tyre wear has increased
