Unfortunate they’ll likely label your rotors as a wear item, which given many last 50k+ miles isn’t entirely true. Maybe BMW may cover them?

 

The only times I've had Hill Hold not hold is when i don't get it a firm quick squeeze. A more gradual or less full squeeze seems to not trigger it quite right.

I noticed the same pulsing on mine, and on my car too. The rotors are either warped or have some contaminates on the surface. My car got that way after some aggressive driving in the mountains...got them too hot I suppose and the result was warping.

 

Dealer says both frt rotors have “heat marks”, and replacements not warranty item. Wondering if other owners have had the pulsing issue and replaced OEM’s with EBC or other aftermarket components? Which one(s) would be a good quality replacement?

 

Had the pulsing problem on a 2000 Triumph Sprint ST the solution was changing the from stock to EBC sintered HH, Ferodo is also good and of course aftermarket Brembo pads. As you apply the brakes the pads deposit material on the rotors and then wipe that material off as the wheel rotates, sometimes this does happen as intended and you get pulsing when you apply the brakes.
As for the the hill assist not staying applied, I noticed on my '19 1250GS that the rear brake pedal was getting spongy and my hill assist did not hold. Bled the rear brake and everything worked as expected. Just anecdotal evidence from my side.

Had a 2015 Triumph Trophy also with pulsing frt brakes, but much worse than the GS. The solution then was to replace with OEM, but dealer did it under warranty. I forget the mileage, but the issue started up again before the bike got totaled at 42,000 miles. At the time, according to the Trophy forum, the pulsing problem was fairly common on that bike.

 

Update: Dealer replaced frt rotors/pads. Have only ridden 9 miles since. Will provide more feedback after a healthy ride.

 

Update: Dealer installed new OEM rotors and pads. I’ve put approx 500 miles on them and so far so good. Dealer actually stepped up and absorbed most of the cost. All is well in BMWland again.

 

Barab42 did putting the discs on fix the hill hold also?

 

I don’t think changing the rotors would affect the HH. i’ve since had the brake system flushed, and presently the HH works well.

 

I did wonder to be honest the wife has just had a 1250 and her Hill start doesn't work at all unless in neutral soo bizarre I have flushed the system even took to dealer for software update but still no joy, literally she pulls up in gear and tryies to squeeze the brake to apply the hill start it initially comes on then no more than 1 second it turns back off. Bmw say the onky way it can turn itself back off is if the bike sees wheels speed or recognises engine load unless of course ur manually turn it back off. Really frustrating as I can not get to the bottom of it. Any recommendations greatly appreciated lol
Thanks

 

Re HH: Dealer sd should work in N or in 1st. Originally it worked only in N, but now it works in either case.
