PROCEDURE
1. |
PERFORM ROAD TEST |
(a) After turning the ignition switch ON, compare the operating sound of the brake actuator the first time the vehicle speed reaches approximately 25 km/h (16 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 20 km/h (12 mph), the initial check of the brake actuator assembly is performed and pump motor operation sounds are generated.
OK |

2. |
CHECK BRAKE ACTUATOR BOLT CUSHION |
(a) Check that the cushion of the brake actuator bracket assembly is not worn, damaged or deformed.
OK:
The brake actuator bracket assembly is not worn, damaged or deformed.

3. |
ADJUST INSTALLATION OF BRAKE ACTUATOR ASSEMBLY |
(a) Drain the brake fluid.
(b) Disconnect all brake lines from the brake actuator assembly.

NOTICE:
After connecting all the brake lines, add brake fluid and bleed the brake system.

HINT:
By reducing the tension on the brake lines and cushion, the operating sound of the brake actuator assembly may be reduced.
(d) Check that no brake lines interfere the vehicle body or other components.

4. |
RECHECK SYMPTOM |
(a) Perform a road test and check the magnitude of the operating sound again.
OK:
The operating sound is the same or quieter than that of a known good vehicle of the same model.
OK |
USE SIMULATION METHOD TO CHECK |
