Bleeding Service Brakes (S.N. -880907)
CAUTION:
Prevent possible injury from reduced brake capacity. Do not operate machine if pedal travel exceeds 133 mm (5.25 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.
1.
Engage park brake. Lock brake pedals so to bleed both brakes at the same time.
2.
Operate engine at high speed and cycle a hydraulic function such as the loader bucket to fill brake reservoir.

3.
Release brake pedals completely and wait a minimum of 10 seconds.
4.
Repeat steps 2 and 3 until a firm pedal is obtained with pedal travel within specified distance of 133 mm (5.25 in.) or less. Brakes will continue to self-bleed as you operate machine and pedal firmness should improve.
