Any suggestions for upgrading my brakes please?

[ProdigalGS]

I'm just back from a long trip round Europe on my 2017 R1200GS. The bike ran perfectly but the brakes require a big squeeze when you want to stop in a hurry. It's done 20,000 miles on the original discs and pads, so they are due a change soon anyway. I'd love to fit more responsive brakes and was wondering who has tried what.

The simple option would be aftermarket pads, like EBC or Brembo, and new BMW discs. EBC seem to get the best reviews, does anyone have any relevant experience to share?

Option 2 is to fit some floating discs like these from Sunstar in Japan as well. I have bought Sunstar floaters before for a Kawasaki special and I thought they were excellent. Bit more expensive than OE discs but not too excessive. I think they look great too, but maybe not with the orange pins!

Option 3 is to fit Brembo Stylema calipers too. They are simple bolt-on replacement, although I would have to remove the locating dowels that BMW uses. You can get new ones on ebay for about £400 a pair.

Any constructive suggestions would be appreciated. Thanks!

R1200/1250RT front discs , set of 7.5mm spacers for the calipers and uprated pads (did it on my 2015 GSA and it worked ) , or alternatively Galfer or Braking do a kit which includes larger discs, spacers and upgraded pads

I'd start by bleeding the system and servicing the calipers and replacing the pads.
Take a look at the way it is yt channel. He has a good video on pads and servicing calipers.

The bike was serviced with new brake fluid a few months ago, but the calipers weren't touched as far as I know.

Thanks Neil, what pads did you use with the RT discs? I saw the Braking 320mm disc conversion, which looked like a possible option. Honda did something similar on the Fireblade many years ago, bigger discs with caliper spacers.

I use the original discs and EBC EPFA pads, much better

EBC HH were more than enough for two up in the Alps , no brake fade and it did make a difference with the bigger discs

The OE braking system should be perfectly adequate so, before you go raiding your credit card for an upgrade, surely it's best to have a detailed overhaul your existing system.

The usual issue is the rear brake not sliding smoothly on the pins, leading to the disc overheating, which shows up as long pedal travel &/or brake fade. If you were experiencing this issue in the mountain switchbacks, but not so much elsewhere, it points to brake fade & the need to overhaul all 3 calipers & the master, whilst checking the discs for discoloration, high spots & run-out & the pads for glazing. There are plenty of pad options, so just check using 'search' - EBC HH seem popular.

A fluid change & ABS bleed is due every 2 years IIRC, but the dealer won't be looking deeper unless an issue is reported or something is obviously amiss.

strip and reseal the calipers , clean everything to within an inch of its life .
pistons if it needs them . bleed them properly , for pads i would choose Ferodo ST pads ( if still available. )
lube your pivot pin at the lever.

ask for Paul. he is a most helpful chap .
if your discs are worn out at 20k , i would be surprised .
the thickness marked on the disc is NOT the wear limit , that is for guidance if you are refinishing them.
( bmw owners are suckers for letting shops tell them it is the wear limit ) if in doubt , measure a new disc.

i changed my discs at 80k miles on my 1150 , cos the MOT tester thought they were thin. ( i did it 11 months later )
