Quality Standards for a Reliable Brake Booster

When you buy used brake parts online, absolute reliability and pressure retention are critical. Here are the quality standards for every Falcon brake booster:

  • 1. Vacuum Leak Test: We apply vacuum pressure to ensure the internal rubber diaphragm holds a seal without bleeding off.
  • 2. Master Cylinder Check: The front opening is inspected to ensure brake fluid from a bad master cylinder hasn't ruined the inside.
  • 3. Pushrod Inspection: The pedal input rod and master cylinder output rod are verified perfectly straight.
  • 4. Check Valve Verification: We test the plastic vacuum check valve (if equipped) to ensure air only flows one way out of the booster.
  • 5. Housing Integrity: The metal or plastic outer casing is checked for dents, rust, or cracks that could cause a loss of vacuum.
  • 6. Direct VIN Matching: We verify your VIN to ensure the exact booster diameter and pushrod length for your specific brake package.

Common Questions About Buying Used Brake Boosters

The cost of a used brake booster typically ranges from $50 to $150 for standard vacuum boosters. Heavy-duty hydroboost units for diesel trucks or advanced electronic boosters for modern luxury vehicles can range from $150 to $300+.

A brake booster multiplies the force you apply to the brake pedal. It uses engine vacuum or hydraulic pressure from the power steering pump to help push fluid through the master cylinder, allowing you to stop a heavy vehicle with minimal physical effort.

Common symptoms include a very stiff or "hard" brake pedal, a hissing noise coming from under the dashboard when you press the pedal, increased stopping distances, or your engine stalling/idling poorly when braking.

A vacuum booster uses engine vacuum pressure to assist braking and is found on most standard cars. A hydroboost uses hydraulic fluid pressure from the power steering pump and is typically found on heavy-duty trucks or diesel engines where engine vacuum is low.

For vacuum boosters, we use a vacuum pump gauge to ensure the internal rubber diaphragm holds pressure without bleeding off. We also inspect the pushrod for straightness and check the interior for brake fluid contamination.

Usually, the brake booster is sold as a standalone unit. The master cylinder, which bolts to the front of the booster, is typically sold separately, though we sometimes have complete booster/master cylinder assemblies available.

Yes. If the internal diaphragm of a vacuum brake booster tears, it creates a massive vacuum leak. This allows unmetered air into the engine intake, which can cause a rough idle, misfires, or stalling when you press the brakes.

No, it is highly dangerous. While the brakes will technically still work, it requires an immense amount of leg force to stop the vehicle, significantly increasing your stopping distance and the risk of an accident.

Replacing a brake booster involves unbolting it from the brake pedal assembly under the dashboard, unbolting the master cylinder in the engine bay, and maneuvering the unit out. It requires some mechanical skill and tight access under the dash.

Used OEM brake boosters are manufactured to the exact factory specifications, ensuring the pushrod length is perfectly calibrated. Cheap aftermarket boosters often have incorrect pushrod lengths, causing brakes to drag or requiring excessive pedal travel.
