Toyota Corolla Cross: Brake Actuator Operation Sound is Loud during Initial Check
PROCEDURE
|
1. |
PERFORM ROAD TEST |
(a) After turning the ignition switch to ON, compare the operating sound of the brake actuator the first time the vehicle speed reaches 45 km/h (28 mph) with a known good vehicle of the same model.
OK:
The operating sound is the same or quieter than that of a known good vehicle of the same model.
HINT:
When the vehicle speed reaches approximately 40 km/h (25 mph), the initial check of the brake actuator assembly is performed and pump motor operation sounds are generated.
