Aeroflow Performance AF59-1051 Brake Vacuum Switch and Tee

Radical camshaft profiles, forced induction setups, and large-displacement engine builds often suffer from low idle manifold vacuum, compromising your brake booster’s performance and leaving you with a hard pedal. The Aeroflow AF59-1051 Brake Vacuum Switch and Tee provides the critical control component needed to operate an auxiliary electric vacuum pump, ensuring your power brakes always have consistent, reliable vacuum assist.

This kit includes a precision-calibrated vacuum switch paired with a matching tee fitting, allowing you to plumb the switch seamlessly into your vehicle’s vacuum line. The switch automatically triggers your electric vacuum pump when manifold pressure drops below the safety threshold, keeping your braking system fully primed and responsive under all driving conditions.

Key Features:

• Automated System Control: Accurately monitors vacuum levels and switches on an auxiliary electric pump when boost or low vacuum occurs.

• Complete Installation Kit: Supplied with both the pressure/vacuum switch and a dedicated tee fitting for straightforward plumbing.

• Enhanced Safety: Restores firm, consistent pedal feel and dependable power brake assist on modified or forced-induction vehicles.
