INSPECT THE ELECTRIC
PARKING BRAKE
Motor Brake
Test equipment required: A variable power supply
capable of supplying 0-volts to 24-volts DC at 2-Amps.
The brake does not have to be removed from the
transmission for this test.
6. Disconnect the electric brake connector from the
vehicles harness.
7. Adjust the power supply to zero volts.
8. Connect the power supply to the electric brake.
9. Slowly increase the voltage until you hear a ‘click’
from the brake. The ‘click’ is the brake releasing.
The motor should now be free to rotate (limited by
the gear train and parking brake).
a) If the brake does not release until the voltage
exceeds 18-volts, then the friction plate has worn
beyond its service limits and must be replaced.
b) If the brake does not release at all, then the
brake electromagnet has failed and must be
replaced.
10. Reconnect the electric brake.
11. Reconnect the main positive and negative cables
at the batteries.
12. Remove blocks from behind the wheels.
13. Test drive the vehicle.
ADJUST THE SERVICE
BRAKES
The hydraulic disc brake system is automatically
adjusted. A low brake pedal or lack of braking power
could be caused by:
•
Brake fluid level low in the master cylinder. See
Check the Master Cylinder Fluid
section.
•
Air in the brake lines. See
Bleed the Brakes
section.
•
Worn brake pads. See
Inspect the Service Brake
section.
•
Worn brake rotor. See
Inspect the Service Brake
section.
•
Binding brake pedal linkage.
If you are experiencing a low brake pedal or lack of
braking power, the entire brake system should be
inspected.
1. Make sure the key-switch is in the “OFF”
position, then remove the key.
2. Place the forward-reverse switch in the
center “OFF” position.
3. Confirm the electric park brake is applied.
4. Place blocks under the front wheels to
prevent vehicle movement.
5. Disconnect the main positive and negative
cables at the batteries.
