12-8 BRAKES Brake Fluid
Brake Line Air Bleeding
The brake fluid has very low compression coefficient so that almost all the movement of the brake pedal is transmitted directly to the caliper for braking actionAir, however, is easily compressedWhen air enters the brake lines, brake pedal movement will be partially used in compressing the airThis will make the lever or pedal feel spongy, and there will be loss in braking power
WARNING
Be sure to bleed the air from the brake line whenever brake pedal action feels soft or spongy after the brake fluid is changed, or whenever brake line fitting has been loosened for any reason
