BRAKES

1981 Toyota Pickup • 4 cylinder 2WD Manual • 125,000 miles

The fluid in the master cylinder seems to disappear while the truck is setting, not running. What is the problem?

Check all rubber hoses, steel brake lines, calipers, and wheel cylinders for leaks. If nothing is found, check the master cylinder. It could be leaking out the back.
