Product Details

The Genuine BMW 34-33-7-577-336 Brake Booster Vacuum Hose is an OEM replacement vacuum line engineered to restore proper brake booster function on BMW E82, E9X, and related chassis models. This hose connects to the brake booster and forms one section of a multi-section vacuum hose assembly that supplies the negative pressure required for power-assisted braking.

When the brake booster vacuum hose cracks, hardens, or develops leaks, the booster loses the vacuum signal it needs to amplify pedal effort — resulting in a hard brake pedal and reduced stopping performance. Replacing it with a Genuine BMW part ensures an exact OEM fit and restores the vacuum system to factory specification.

Key Features:

  • Genuine BMW OEM part — manufactured to original factory specifications
  • Direct replacement for the brake booster vacuum supply line
  • One section of a three-section vacuum hose assembly
  • Designed for exact fit with no modification required
  • Restores proper brake booster vacuum and pedal feel
  • Cross-reference part numbers: 34-33-7-577-336, 34337577336, 34336768042, 34336766079

This is a Genuine BMW component, ensuring the precise engineering tolerances and material quality needed for reliable, long-term brake system performance.

Good parts good prices

Good experience!

I ordered the products, the products were delivered, and I was satisfied. A good transaction.

Great

I received exactly what I ordered and received the fed/exactly ground in 3 days. A job well done.

Ordered replacement seats for my fishing boat. I was shocked and impressed with the quality of the seats. They look as good as the originals from Tracker. Shipping was great, arrived sooner than I expected.

Great prices and a surprisingly fast delivery, which despite choosing the most economic choice (2-14 days), I received the items in 5 days - saved more than half in shipping. Great all around experience and great product extremely well packaged. Thank you, folks!
