A hydraulic brake uses liquid pressure to transfer force from the brake pedal to the brake drum to stop a vehicle. In this working model, you will show how pressing a “brake pedal” moves hydraulic fluid (water or oil) through a tube to push a “brake shoe” against a “drum” (wheel). Working Principle Demonstrated: Pascal’s … Read more
