## Two braking systems work together
A hybrid vehicle may recover energy during deceleration while also using conventional friction brakes. The balance can change with speed, battery condition, temperature and driving conditions.
## Symptoms that deserve attention
Noise, unusual pedal feel, warning messages, vibration or a change in braking response should be inspected. The cause may be mechanical, electrical or related to system control.
## Service with system awareness
A suitable inspection looks at brake hardware and available hybrid diagnostic information together, while following the vehicle's safety procedure.
