Trusted Source for High-Quality Used Brake Valves

When you hit the brakes hard and your rear tires immediately lock up and skid, your brake proportioning valve has failed. Don't risk your safety with mismatched aftermarket parts that mess up your vehicle's factory brake bias. Falcon Car Parts is your premier source for exactly matched, genuine used brake proportioning valves for sale.

Every used brake bias valve in our inventory is carefully removed and put through a physical integrity check. We ensure the valve body is not leaking, the internal plunger isn't seized, and the threaded flare nut ports are in perfect condition.

  • Thread Inspection: Every fluid port is checked to ensure your brake lines will seal tightly.
  • Leak-Free Guarantee: We reject valves showing signs of internal seal blowout or external weeping.
  • OEM Calibration: Factory valves provide the exact fluid restriction your specific braking system requires.

Quality Standards for a Reliable Brake Valve

When you buy used hydraulic brake parts online, the internal condition and thread integrity are everything. Here are the quality standards for every Falcon brake valve:

  • 1. Port Thread Inspection: The inlet and outlet ports are checked to ensure the threads aren't cross-threaded or stripped by careless removal.
  • 2. Leak Assessment: The valve body is thoroughly inspected for brake fluid residue, indicating a blown internal O-ring.
  • 3. Body Integrity: Cast iron or aluminum housings are checked for external rust rot and stress fractures.
  • 4. Bleeder Check: If the valve features an integrated bleeder screw, we ensure it is not snapped off or seized.
  • 5. Load-Sense Linkage: For truck valves, the mechanical spring arm mechanism is checked to ensure it moves freely.
  • 6. Direct VIN Matching: We use your VIN to ensure exact calibration for your vehicle's specific weight distribution and brake rotor size.

Common Questions About Buying Used Brake Proportioning Valves

The cost of a used brake proportioning valve typically ranges from $40 to $120. Load-sensing proportioning valves for heavy-duty trucks or specialized ABS-integrated valves may fall on the higher end of the spectrum.

It restricts brake fluid pressure sent to the rear brakes during heavy braking. Because weight shifts to the front of the car when stopping, the rear wheels have less traction. The valve prevents the rear wheels from locking up and causing a spin-out.

Common symptoms include the rear wheels locking up easily on wet or slick roads, the car nosediving severely when braking, a spongy brake pedal, or visible brake fluid leaking from the valve body itself.

No, bypassing the proportioning valve is extremely dangerous. Sending full, unregulated hydraulic pressure to the rear brakes will cause them to lock up almost instantly during a panic stop, leading to a dangerous loss of vehicle control.

Yes. Drum brakes require a residual pressure valve to keep slight tension on the drum springs, while disc brakes do not. You must replace your valve with an exact OEM match designed for your specific brake setup (e.g., front disc/rear drum vs. 4-wheel disc).

Commonly found on pickup trucks, a load-sensing valve connects to the rear suspension. It automatically increases brake fluid pressure to the rear brakes when there is heavy weight in the truck bed, and decreases it when the bed is empty.

We visually inspect the valve body for stress cracks and fluid leaks. We also inspect the threaded brake line ports to ensure they are not stripped or cross-threaded, and verify the internal plunger is not seized from rust.

Yes. Because you are disconnecting hard brake lines and opening the hydraulic system to the atmosphere, you must perform a complete brake fluid bleed to remove all air pockets before driving the vehicle.

For street driving, an OEM valve is much safer and more reliable. It is factory-engineered for your exact vehicle weight and brake size. Adjustable aftermarket valves are primarily designed for custom racing applications and require manual calibration.

If the factory proportioning valve was originally attached to a specific metal mounting bracket near the master cylinder or frame rail, we typically leave the bracket attached to make your installation easier.
