Step 1 (airtanks) |
Chock and block wheels Engine on Spring brake applied Transmission neutral Psi is 105, within NOR |
|
|
Step 2 (airtanks) |
Engine off psi is still NOR, at 100 psi |
|
|
Step 3 (air tanks) |
Locate primary airtank It passes because -it's securely mounted -valve is working -discharge is clear when tank is empty It fails if : -not mounted securely -valve not working -discharge is not clear when tank is empty |
|
|
Step 4( air tanks) |
Locate remaining air tanks They pass if - all mounted securely - all valves working -discharge is clear when tanks are empty Fail if: -any tank is not mounted securely -any valve is not working -discharge from any tank is not clear |
|
|
Step 5(air tanks) |
In conclusion, this vehicles passes the draining air tanks test because -all tanks are securely mounted -all valves are working -discharge in all tanks is clear when tank is empty Thus we can put the bus in revenue service However, it would fail if -any tank was not mounted securely -any valve was not working - discharge in any tank was not clear when tank empty I would put the bus out of service and report the defect |

Step 1 (applied pushrod stroke) |
Chock and block the vehicle Engine is on Spring brake applied Transmission neutral (1st)PSI above 90, currently at 105 psi |
|
|
Step 2 (applied pushrod stroke test) |
Release spring brake Turn off engine PSI is between 90 and 100psi, currently at 95 psi |
|
|
Step 3 (applied pushrod stroke) |
Ensure it's clamp style Mark push rod where it meets the brake chamber for each brake Ensure psi is between 90 and 100, currently at 95 |
|
|
Step 4 (applied pushrod stroke) |
Assistant please make and hold a full service brake application Measure mark Secure the bus Write measurement in mm |
|
|
Step 5 (applied pushrod stroke) |
Find brake size Write size and adjustment limit Compare |
|
|
Step 6 (applied pushrod stroke) |
The brake is type, size,etc. It passes because the measurement I took is equal too or less than the adjustment limit. I can take this bus for revenue service However it would have failed if the measurement was greater than the adjustment limit |
