PARKING BRAKE LEVER STROKE CHECK AND ADJUSTMENT

Attach the spring scale to the center of the parking brake lever grip. Then, check that the stroke is within the standard value when the parking brake lever is pulled to the vertical direction of the lever with a force of approximately 200 N (45 pounds).

Standard value: 3 to 5 notches

STROKE ADJUSTMENT < VEHICLES WITH REAR DRUM BRAKE >

If the parking brake lever stroke is out of the standard range, adjust as described below

Scheme 2

Scheme 3

1. Remove the floor console box cup holder (Refer to «FLOOR CONSOLE ASSEMBLY»(/mitsubishi/lancer-evolution/x-2007-2016/remont/gauges-instrument-panels/#interior-except-lancer-evolution) ).
2. Loosen the adjusting nut to the end of the cable rod in order to allow slack in the cables.
3. Depress the brake pedal repeatedly until the stroke no longer changes. NOTE: If the pedal stroke stops changing, the automatic-adjustment mechanism is functioning normally, and the clearance between the shoe and drum is correct. CAUTION: Be careful that the parking brake lever notch number should be within the standard range. If the notch number is too low, rear brake dragging can be caused.
4. Adjust the parking brake lever stroke to the standard value by turning the adjusting nut. After adjustment, check that there is no free play between the adjusting nut and the parking brake lever.
5. After the parking brake lever stroke is adjusted, raise the rear of the vehicle. Release the parking brake, and turn the rear wheels to confirm that the rear brakes are not dragging.

STROKE ADJUSTMENT < VEHICLES WITH REAR DISK BRAKE >

If the parking brake lever stroke is out of the standard range, adjust as described below

Scheme 4

1. Remove the floor console box cup holder (Refer to «FLOOR CONSOLE ASSEMBLY»(/mitsubishi/lancer-evolution/x-2007-2016/remont/gauges-instrument-panels/#interior-except-lancer-evolution) ).
2. Loosen the adjusting nut to the end of the cable rod in order to allow slack in the cables.
3. Remove the rear brake disk adjusting hole plug. Then insert a flat-tipped screwdriver to turn the adjuster to the arrow direction shown in illustration (to expand the shoe) until the parking brake shoe makes contact and the disk can no longer be turned. Back off the adjuster to the opposite direction by five notches. CAUTION: Be careful that the parking brake lever notch number should be within the standard range. If the notch number is too low, rear brake dragging can be caused.
4. Adjust the parking brake lever stroke to the standard value by turning the adjusting nut. After adjustment, check that there is no free play between the adjusting nut and the parking brake lever.
5. After the parking brake lever stroke is adjusted, raise the rear of the vehicle. Release the parking brake, and turn the rear wheels to confirm that the rear brakes are not dragging.

PARKING BRAKE SWITCH CHECK

Scheme 5

1. Remove the floor console assembly (Refer to «FLOOR CONSOLE»(/mitsubishi/lancer-evolution/x-2007-2016/remont/gauges-instrument-panels/#interior-except-lancer-evolution) ).
2. Check for continuity between the parking brake switch terminal and the switch mounting bolt. PARKING BRAKE SWITCH CONTINUITY CHART Check condition Normal condition When parking brake lever is pulled. Continuity exists (2 ohms or less) When parking brake lever is released. No continuity

PARKING BRAKE LINING SEATING PROCEDURE

Perform lining seating by the following procedure when replacing the parking brake shoe assemblies or the rear brake disks, or when brake performance is insufficient.

1. Adjust the parking brake lever stroke to the standard value (Refer to «PARKING BRAKE LEVER STROKE CHECK AND ADJUSTMENT»(/mitsubishi/lancer-evolution/x-2007-2016/remont/parking-brake-system/#parking-brakes-except-lancer-evolution__parking-brake-lever-stroke-check-and) ).
2. Hook a spring scale onto the center of the parking brake lever grip and pull it with a force of 98 - 147 N (22 - 33 pounds) in a direction perpendicular to the handle.
3. Drive the vehicle at a constant speed of 35 - 50 km/h (22 - 31 mph) for 100 meters (328 feet).
4. Release the parking brake and let the brakes cool for five to ten minutes.
5. Repeat the procedure in steps 2 to 4 four or five times.
