Repair steps
1
Check both levers
Pull and release each lever while watching for slow or incomplete return.
Do not loosen hydraulic hose fittings.
2
Clean the pivot
Wipe dirt from around the lever pivot and operate it several times.
Keep lubricants away from rotors and pads.
3
Check sensor alignment
Inspect the small sensor and magnet near the lever. If obviously displaced, align them without straining the wire.
Stop if wiring is pinched or damaged.
4
Restart and test
Power-cycle the bike, then test the brake icon and motor cut-off with the drive wheel raised.

All checks passed. You’re ready to ride.
