A tandem booster is a type of vacuum power booster used in brake systems to increase the force applied during braking. Here’s how it works:
- Vacuum Power Booster: Like other vacuum power boosters, a tandem booster utilizes vacuum pressure from the engine to assist with brake application. When the driver presses the brake pedal, the booster amplifies the force exerted on the master cylinder, allowing for more effective braking with less pedal effort.
- Dual Diaphragms: What sets a tandem booster apart is its use of two diaphragms instead of one. These diaphragms work in tandem (hence the name) to multiply the force generated by the vacuum, resulting in greater brake application force.
- Increased Force: By employing two diaphragms, a tandem booster can generate higher brake application forces compared to single-diaphragm boosters. This increased force is beneficial for larger vehicles or those requiring greater braking power.
- Compact Design: Despite having two diaphragms, tandem boosters are typically designed to be smaller in diameter than their single-diaphragm counterparts. This compact design allows them to fit into tight spaces within the vehicle’s engine compartment while still providing enhanced braking performance.
Overall, tandem boosters offer improved braking force and efficiency, making them suitable for various vehicle applications where enhanced braking performance is required.
