Chrysler 300/300 Touring/300C, Dodge Magnum. Manual - part 142

FRONT BRAKES

1. If installed, remove rubber dust cap from bleeder

screw on each front brake caliper.

2. Starting at the first wheel circuit that needs to be

bled (See list in above note), attach a clear hose
(1) to the bleeder screw at that wheels brake cali-
per and feed the other end of hose into a clear jar
(2) containing enough fresh brake fluid to sub-
merge the end of the hose.

CAUTION: Open the bleeder screw at least one full
turn when instructed. Some air may be trapped in
the brake lines or valves far upstream, as far as
ten feet or more from the bleeder screw. If the
bleeder screw is not opened sufficiently, fluid flow
is restricted causing a slow, weak fluid discharge.
This will NOT get all the air out. Therefore, it is
essential to open the bleeder screw at least one
full turn to allow a fast, large volume discharge of brake fluid.

3. Open bleeder screw at least one full turn or more to obtain an adequate flow of brake fluid.

4. After 4 to 8 ounces of brake fluid has been bled through the brake hydraulic circuit, and an air-free flow (no

bubbles) is maintained in the clear plastic hose (1) and jar (2), close the bleeder screw.

5. Install bleeder screw dust cap.

6. Bleed opposite front brake wheel circuit as necessary in the same manner until all air is removed from the brake

hydraulic system.

5. If equipped with antilock brakes, the hydraulic control unit may need to be bled, then rebleed base brakes. (Refer

to 5 - BRAKES - STANDARD PROCEDURE)

6. Once all brakes are bled, check brake pedal travel. If pedal travel is excessive or has not improved, some air

may still be trapped in the hydraulic system. Rebleed the brake system as necessary.

7. Test drive vehicle to ensure brakes are operating properly and pedal feel is correct.

MANUAL BLEEDING METHOD

NOTE: To bleed the base brake system manually, an assistants help is required.

NOTE: To ensure all air is bled from the ICU or
junction block in a timely manner, it is recom-
mended to raise the rear of the vehicle approxi-
mately 5° higher than the front or approximately
10–12 inches as measured at the rear bumper (1).

1. Raise and support vehicle placing rear of vehicle

approximately 5° higher than the front or if mea-
sured at the rear bumper (1), approximately 10–12
inches above level. It will be necessary to add
extra support stands under vehicle to support this
angle.

ensure adequate removal of all trapped air from the brake hydraulic system.

REAR BRAKES

1. If installed, remove rubber dust caps from both

bleeder screws on each caliper.

2. Starting at the first wheel circuit that needs to be

bled (See list in above note), attach a clear hose
(3) to the inboard bleeder screw (2) at that wheels
brake caliper and feed the other end of hose into a
clear jar (4) containing enough fresh brake fluid to
submerge the end of the hose.

3. Have an assistant pump the brake pedal three or

four times, then hold it down before the bleeder
screw is opened.

CAUTION: Open the bleeder screw at least one full
turn when instructed. Some air may be trapped in
the brake lines or valves far upstream, as far as
ten feet or more from the bleeder screw. If the
bleeder screw is not opened sufficiently, fluid flow
is restricted causing a slow, weak fluid discharge.
This will NOT get all the air out. Therefore, it is
essential to open the bleeder screw at least one full turn to allow a fast, large volume discharge of brake
fluid.

4. While the pedal is being held down, open the inboard bleeder screw (2) at least one full turn. When the bleeder

screw opens the brake pedal will drop all the way to the floor. Continue to hold the pedal all the way down.

5. Once the brake pedal has dropped, close the bleeder screw. The pedal can then be released.

6. Repeat the above three steps until all trapped air is removed from that wheel circuit (usually four or five times).

This should pass a sufficient amount of fluid to expel all the trapped air from the brakes hydraulic system. Be
sure to monitor brake fluid level in master cylinder fluid reservoir making sure it stays at a proper level.
This will ensure air does not reenter brake hydraulic system through master cylinder.

NOTE: Monitor the brake fluid level in the fluid reservoir periodically to make sure it does not go too low.
This will ensure that air does not reenter the brake hydraulic system.

7. Remove clear hose and install bleeder screw dust cap.

8. Attach a clear hose (5) to the outboard bleeder

screw (1) at that same wheels brake caliper and
feed the other end of hose into a clear jar (4) con-
taining enough fresh brake fluid to submerge the
end of the hose.

9. Have an assistant pump the brake pedal three or

four times, then hold it down before the bleeder
screw is opened.

10. While the pedal is being held down, open the outboard bleeder screw (2) at least one full turn. When the

bleeder screw opens the brake pedal will drop all the way to the floor. Continue to hold the pedal all the way
down.

11. Once the brake pedal has dropped, close the bleeder screw. The pedal can then be released.

12. Repeat the above three steps until all trapped air is removed from that wheel circuit (usually four or five times).

NOTE: Monitor the brake fluid level in the fluid reservoir periodically to make sure it does not go too low.
This will ensure that air does not reenter the brake hydraulic system.

13. Remove clear hose and install bleeder screw dust cap.

14. Bleed opposite rear brake wheel circuits as necessary in the same manner until all air is removed from the

brake hydraulic system, then proceed to the front brakes.

FRONT BRAKES

1. If installed, remove rubber dust cap from bleeder

screw on each front brake caliper.

2. Starting at the first wheel circuit that needs to be

bled (See list in above note), attach a clear hose
(1) to the bleeder screw at one wheel and feed the
other end of the hose into a clear jar (2) containing
fresh brake fluid.

3. Have an assistant pump the brake pedal three or

four times and hold it down before the bleeder
screw is opened.

CAUTION: Open the bleeder screw at least one full
turn when instructed. Some air may be trapped in
the brake lines or valves far upstream, as far as
ten feet or more from the bleeder screw. If the
bleeder screw is not opened sufficiently, fluid flow
is restricted causing a slow, weak fluid discharge. This will NOT get all the air out. Therefore, it is essential
to open the bleeder screw at least one full turn to allow a fast, large volume discharge of brake fluid.

4. While the pedal is being held down, open the bleeder screw at least one full turn. When the bleeder screw opens

the brake pedal will drop all the way to the floor. Continue to hold the pedal all the way down.

5. Once the brake pedal has dropped, close the bleeder screw. The pedal can then be released.

6. Repeat steps One through Five until all trapped air is removed from that wheel circuit (usually four or five times).

sure to monitor brake fluid level in master cylinder fluid reservoir making sure it stays at a proper level. This will
