Unlike the Half Cross Tent Stitch, the Continental Stitch can be used on any type of needlepoint canvas and provides excellent coverage that makes the finished needlework sturdy enough to last a lifetime. Take a look at the image above. It shows the front...MORE and back sides of the Continental Tent Stitch.
A brake booster is an enhanced master cylinder setup used to reduce the amount of pedal pressure needed for braking. It employs a booster set up to act with the master cylinder to give higher hydraulic pressure to the brakes and/or lower force applied on the brake pedal through a brake booster push-rod.
The Vacuum Booster. Â­ Â­The vacuum booster is a metal canister that contains a clever valve and a diaphragm. A rod going through the center of the canister connects to the master cylinder's piston on one side and to the pedal linkage on the other. Another key part of the power brakes is the check valve. The photo above shows the check valve, which is a one-way valve that only allows air to be sucked out of the vacuum booster. If the engine is turned off, or if a leak forms in a vacuum hose, the check valve makes sure that air does not enter the vacuum booster.
