Rein OE Manufactured Brake Vacuum Pumps are produced in an OE factory to the specifications of the auto maker’s engineers! These brake vacuum pumps come complete with a mounting gasket or seal, depending on the application. Vacuum pumps are used in vehicles with engines that do not produce sufficient vacuum to provide power to the braking system, EGR valves, intake manifold switches, as well as turbocharger actuators and others. A failed or improperly working brake vacuum pump can lead to a reduction in braking power, a reduction in part and/or full load performance, a triggering of check engine light or limp mode, or engine misfires. All Rein brake vacuum pumps are manufactured by an OE manufacturer and are the exact same units that originally came on the vehicle!

Product Features:

• Ensures the proper operation of vehicle’s braking as well as all other vacuum dependent systems
• Engineered and manufactured by an OE manufacturer
• Plug and play replacement for original vacuum pump
• Applicable gasket included

Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.
