If your vehicle experiences a total hydraulic brake failure while traveling on a highway, in what correct sequential order should you perform the following emergency recovery actions?
- 1Downshift the transmission into a lower gear to utilize engine braking.
- 2Pump the brake pedal rapidly several times to attempt building up residual hydraulic pressure.
- 3Gently apply the emergency or parking brake while holding the lever or button release.
- 4Steer safely toward the road shoulder or an open escape area, bring the car to a stop, and turn on hazard lights.
Cevap
The correct emergency sequence for managing total brake failure is: first downshift into a lower gear to use engine braking, second pump the brake pedal rapidly to build pressure, third gently apply the parking brake while holding the release mechanism, and finally steer safely onto the shoulder and activate hazard lights.
When total brake failure occurs, the driver must first engine brake by downshifting to slow momentum safely. Next, pumping the brake pedal may build residual hydraulic pressure. If pressure fails, using the emergency brake gently while holding the release control provides manual friction without locking the rear wheels. Finally, steering off the road to a safe area and turning on hazard lights completes the stopping procedure safely.
