Crown Automotive 4581586AB Brake Booster Vacuum Pump for 12-18 Jeep Wrangler JK with 3.6L Engine

If you have noticed that your Jeeps brakes are starting to feel a little spongy, you may need a Crown Automotive Brake Booster Vacuum Pump or new booster or vacuum pump. Wrangler JK started using vacuum boosters for brake assist in 2012 as the market cried out for safer and more aggressive braking power. This pump helps to provide the brake booster with the vacuum needed to power the stronger brakes and stop the Jeep. The only drawback is that a pump has a definite. lifespan, so the more you love your Jeep the more your drive and the longer the pump runs. This is not an increase over the factory vacuum but a replacement that attaches to the original electrical harness and booster without splicing or adapters.
