inspected for pedal travel, which is the distance the pedal
moves toward the floor from a fully-released position.
Inspection should be made with the brake pedal firmly
depressed (approximately 50 lbs. on manual brakes or 100 lbs.
on power brakes while the brakes are cold.

BLEEDING BRAKE HYDRAULIC
SYSTEM
A bleeding operation is necessary to remove air
whenever it is introduced into the hydraulic brake system.
It may be necessary to bleed the hydraulic system at all
four wheel cylinders if air has been introduced through low
fluid level or by disconnecting brake pipes at master cylinder.
If brake pipe is disconnected at any wheel cylinder, then that
wheel cylinder only need be bled. If pipes are disconnected
at any fitting located between master cylinder and wheel
cylinders, then all wheel cylinders serviced by the
disconnected pipe must be bled.
