ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT BRAKE BOOSTER ASSEMBLY
(a) Airtightness check
| (1) Start the engine and stop it after 1 or 2 minutes. Slowly depress the brake pedal several times. If the brake pedal can be depressed nearly to the floor the first time, but on the 2nd and 3rd time cannot be depressed as far, the brake booster assembly is airtight. |
|
(2) Depress the brake pedal with the engine running, and stop the engine with the brake pedal depressed.
If there is no change in the brake pedal reserve distance while holding the brake pedal depressed for 30 seconds, the brake booster assembly is airtight.
(b) Operation check
| (1) Depress the brake pedal several times with the ignition switch off and check that there is no change in the brake pedal reserve distance when the brake pedal is depressed. |
|
| (2) Depress and hold the brake pedal, then start the engine. If the brake pedal goes down slightly, operation is normal. |
