Bleed Service Brakes (S.N. 880908- )

The service brakes can be bled using one of two methods. Method One does not involve loosening the bleed screws, but requires a considerable amount of pumping the brake pedals. Method Two requires less pumping of the brake pedals, but involves loosening the bleed screws and attaching clear tubing. Use the method that is best for your situation.

All fittings must be inspected for leaks and tightened if leaks occur.

CAUTION: Prevent possible injury from reduced brake capacity. Do not operate machine if pedal travel exceeds 114 mm (4.5 in.) while applying 267 N (60 lb-force). Operating machine with excessive brake travel could cause brakes not to stop machine on first application.

NOTE: Air will "gravity bleed" from brake system through brake valve without use of bleed screws. Brake lines must be inclined toward brake valve.

Low ambient temperature or aeration of oil will slow bleed process.

2. While operating engine at fast idle, turn steering wheel from lock to lock and cycle a hydraulic function, such as the loader bucket, five times.

3. Operate engine at slow idle.

4. Pump left brake pedal five times, allowing 2 seconds between each pump for air to escape.

5. Repeat steps 2-4 until the left pedal is solid.

6. Pump right pedal until pedal is solid, then pump both pedals at the same time until pedals are solid.

8. If unable to obtain firm brake pedal, inspect lines and connections for leakage. If no external leaks, see your authorized dealer.

2. Acquire two pieces of 6.4 mm (1/4 in.) ID clear tubing that are approximately 2438 mm (8 ft) long.

3. Loosen the two service brake bleed screws located on rear axle. Remove the fill cap from the hydraulic reservoir.

4. Attach an end of one of the tubes to one of the bleed screws. Insert the other end into fill neck of the hydraulic reservoir. Do the same for the other tube, but attach it to the remaining bleed screw.

5. Lock the brake pedals together.

6. Start and operate engine at slow idle.

7. Pump brake pedals while turning the steering wheel back and forth to force hydraulic oil into the brake valve reservoir.

8. With brake pedals locked together, pump the pedals until a continuous stream of fluid with no bubbles is seen flowing through the clear tubes.

9. Tighten bleed screws.

10. Check pedal travel.

11. Disconnect the clear tubes from the bleed screws and drain remaining oil inside the tubes into the reservoir.

12. Install reservoir fill cap.

13. If unable to obtain firm brake pedal, inspect lines and connections for leakage. If no external leaks, see your authorized dealer.
