Regenerative and friction braking may be blended by control software, so pedal feel and deceleration can change with battery state, temperature, traction events, and faults.
Why this matters
Understanding the system principle makes the test result more useful and reduces unnecessary disassembly or parts replacement.
Evidence to capture first
- Warning lamps and messages
- Battery state and temperature
- Wheel-speed and stability events
- Friction-brake condition
A disciplined path
- Confirm whether the feel is normal or new
- Scan all relevant modules
- Inspect friction brakes and tires
- Use model-specific calibration and bleeding procedures
Decision point
Brake-by-wire and accumulator systems can pressurize unexpectedly. Follow disabling procedures before service.
