NHTSA Complaint #11464599 — 2020 BMW R 1250 GS

Rear brake becomes soft and non operational after a period of 9 months. Once the brake has become "soft" the rear brake fails to apply caliper pressure and will not slow or stop the rear wheel. Additionally, at this point the automatic or manual hill hold also become non operational. Note... wide spread problem on the majority of BMW GS 2009-2021 as seen on the fourms such as "Adventure Rider" and "R1200GS info" search for "bmw gs soft rear brakes." Brake bleeds are a temporary fix. Replacing the rear brake master cylinder is a temporary fix. Computer bleeding the Bosch ABS module is also a temporary fix. Problem always returns. I am a federal Airframe and Powerplant technician and avionics installer i know brake systems. I already know BMW motorrad will bleed, bleed, then replace the master cylinder then will send a ticket to BMW Germany and not come up with an answer just like all the poor owners on the fourms. I personally service "bleed" my brakes every 6,000 miles to ensure "acceptable" operation.
