Product Details

The ACDelco 1791322 Power Brake Booster Check Valve is a GM Original Equipment replacement part engineered to maintain safe, consistent braking performance. Functioning as a one-way valve, it prevents air from entering the vacuum booster when the engine is off or in the event of a vacuum hose leak, preserving the vacuum needed for power-assisted braking.

Key Features:

  • Acts as a one-way valve to keep air out of the vacuum brake booster
  • Maintains vacuum reserve inside the booster even when the engine is not running
  • Protects braking assist in the event of engine failure or vacuum hose leak
  • Manufactured to GM Original Equipment specifications for precise fit, form, and function
  • Backed by General Motors quality, reliability, and durability standards
  • GM-recommended replacement for your vehicle's original factory component

This ACDelco check valve is built to the same standards as the component originally installed at the factory, ensuring a seamless, direct-fit replacement. Restoring a worn or failed brake booster check valve is a straightforward repair that helps ensure your power braking system functions correctly — even in emergency situations when the engine is off.

Had the absolute best price for a bike carrier. Quick shipping, lots of email feedback so you know what's happening to your order. Highly recommended! AAAAA++++++++++++

I am not happy with my back rack, it arrived all scratched up and I would like a replacement one, I will ship this one back but I am not going to pay for shipping. Please contact me on how u want to handle this. Tim Sullivan

Very quick and easy. And the price is the lowest I've found. Juse wish it would have stated somewhere that you still have to have the keys reprogrammed.

Lets see how it goes

I ordered an AEM intake from Autoplicity because they had the best prices but it was on backorder from AEM. Autoplicity emailed me to let me know right away and sent me a confirmation when it was back in stock. I'll be shopping here again!

Great place to shop online. The best price on the internet and super fast delivery. Shop with Autoplicity, highly recommended.

Good price, quick shipping, no instant refund though!
