BRAKES 10-7
Brake Line Air Bleeding
The brake fluid has very low compression coefficient so that almost all the movement of the brake lever or pedal is transmitted directly to the caliper for braking actionAir, however, is easily compressedWhen air enters the brake lines, brake lever or 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 powerBleed the air from the brake whenever brake lever or pedal action feels soft or spongy, after the brake fluid is changed, or whenever brake line fitting has been loosened for any reason Remove the reservoir cap, and check that there is plenty of fluid in the reservoirThe fluid level must be checked several times during the bleeding operation and replenished as necessaryIf the fluid in the reservoir runs completely out any time during bleeding, the bleeding operation must be done over again from the beginning since air will have entered the line With the reservoir cap off, slowly pump the brake lever or pedal several times until no air bubbles can be seen rising up through the fluid from the holes at the bottom of the reservoirThis bleeds the air from the master cylinder end of the line
