How the Vacuum Booster Adds Force
On a petrol vehicle the booster draws its vacuum from the engine’s inlet manifold; on this bench unit the motorised vacuum pump takes that role. In a vacuum booster, vacuum acts on both sides of a diaphragm while the brake is off. Applying the brake lets atmospheric air into the rear side, and the pressure difference across the diaphragm pushes on the master cylinder, adding to the effort at the lever.
From Master Cylinder to Brake Shoes
The master cylinder turns the boosted push into pressure in the brake fluid. That pressure reaches the wheel cylinder, whose pistons move outwards and press the brake shoes against the drum. With the parts sectioned, students can follow each stage from lever to booster, master cylinder, wheel cylinder and shoes.
Mechanical, Air and Hydraulic Brake Units
- Internally Expanding Mechanical Drum Brake System — pin-pivoted shoes spread by a cam-lever instead of a wheel cylinder.
- Air Brake Actual Working — a sectioned full-size unit with air tank, air booster, shoes and drums.
- Model of Hydraulic Brake Unit Four Wheel Type — two front disc brakes and two rear drum brakes from original parts.
This unit is one of the brake trainers in the I.C. Engine Lab section; the wider group is Fluid Mechanics and Hydraulics Lab Equipment.
