The hydraulic service brakes fail in a car with a conventional hand-operated parking brake. Which sequence can help slow the vehicle?
Correct answer: Pump the pedal, ease on the parking brake, downshift.
Why
Try pumping the service-brake pedal to restore pressure. If that fails, apply the hand-operated parking brake gradually, ready to ease it if the wheels lock. Shift to lower gears and steer toward a safe stopping place. Keep steering control; never turn the ignition to LOCK while moving. This is a brake-failure procedure, not the technique for a working ABS emergency stop.
