Quality-Built B1049 Dual Diaphragm Vacuum Power Brake Booster

The Quality-Built B1049 is a dual diaphragm vacuum power brake booster, also called a brake booster. It uses engine vacuum to multiply the force you apply at the brake pedal, so the brakes respond with less effort.

Key Features:

• Every unit is pressure tested to confirm leak-free performance
• Every unit goes through end-of-line testing
• Rust-preventive finish helps protect the booster from the elements
• Polished power chambers and calibrated push rods
• Mounting nuts and washers are included, built to OE specifications
• Threaded ports are checked to help prevent cross-threading during installation

The B1049 is built to meet OE performance specifications for durability and pressure transfer. That makes it a straightforward replacement for a worn or leaking power brake booster.
