Hello guys, I've just happen to encounter this weird behavior on my 2018 r1. The braking power indicator on the dash starts at max value while no brake are applied. I can move the bike freely, I cannot feel any braking from the front/rear wheel. I tried to ride it around the block to test if everything works fine, the abs is working on both wheels. The indicator seems to get back slowly to min value after a while. Once I remove the key and put it back on the problem seems to happen again. Any idea on what's going on ? I recently changed the brake fluid could it be the cause? Thank you!
The brake pressure sensor is failing in the ABS unit under the seat. Two pressures are measured by the Bosch ABS unit. One is from the brake lever to the ABS unit and the other is pressure applied to the brake pistons by the ABS unit.
Options to fix:
1. Remove your ABS completely and use an ABS delete plug to prevent error codes,
2. Get it replaced under warranty, or
3. Buy a new ABS at ~1000 USD.
