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.
A Vacuum Servo also known as a power booster or power brake unit uses a vacuum to multiply the drivers pedal effort and apply that effort to the master cylinder. The vacuum can be generated in two distinct methods, dependent on the type of internal combustion engine, or other motive force (as in electric vehicles).
