PBUJ7486D 8″ Dual Power Brake Booster Conversion Kit

Product Description

What is a brake booster?

A brake booster increases the force applied to the brake pedal, amplifying the hydraulic pressure delivered to the master cylinder. This allows for more effective braking, making it an essential safety feature for any vehicle.This technology, also known as “power brakes,” utilizes vacuum pressure to reduce the force required to stop the car. However, like any other technology, brake boosters may experience a malfunction. Although infrequent, knowing the signs indicating a faulty power brake booster is essential. It is pertinent to note that brake boosters are present in almost all cars equipped with hydraulic brakes, while vehicles using pressurized air systems as their primary brake circuits do not require them.

What is the role of a Brake Booster?

An automobile equipped with disc brakes relies heavily on the brake booster to stop. Brake boosters, which are located under the hood, provide additional braking force and aid in stopping your vehicle. Without it, stopping distances would increase substantially, increasing the likelihood of a collision between the driver and passengers during an emergency stop.The diaphragm (the vertical piece) pulls on the rod as it transfers the force exerted to the brake pedal, increasing the force against the master cylinder piston. The combined force simply and swiftly slows the automobile. The valve closes when the brake pedal is released, and the system restores to equilibrium.By adding force to the master cylinders, which dispenses the pressurized fluid that triggers the brakes, brake boosters lessen the effort required to apply the brakes. Aside from the damage to your car, it is extremely dangerous for you and others on the road to drive with a faulty brake booster.

What are the signs that your brake booster needs replacement?

Brake Pedal Resistance

A faulty brake booster makes pressing the brake pedal much more difficult. The booster’s ability to apply additional force against the master cylinder piston diminishes as it fails. The vehicle’s driver is now responsible for all braking power, which is challenging.The brake pedal will feel like it has lost its resistance and become much harder to push. The vehicle may also shudder when braking, especially when going downhill.

Braking Distance Increased

When a brake booster fails gradually, the performance loss is more difficult to detect. If the brake pads and rotors appear to be in decent condition, the brake booster could be to blame.Over time, the brake booster will lose its ability to generate enough vacuum to apply the brakes effectively. This causes an increase in the distance needed to stop your vehicle. The problem may become apparent when slowing down during high-speed driving or while braking on inclines.

Position of the Brake Pedal

You may notice that the brake pedal “travels” less than typical when the brakes are engaged, in addition to the harsher resistance of the brake pedal under pressure. The pedal return may be slower than usual if the booster chambers are out of balance.

Engine Malfunction

The brake booster can suck air into the induction system through a hole in the diaphragm which can affect the fuel mix in the engine since the booster is connected to the primary air intake. In newer, fuel-injected vehicles, the computer compensates for the discrepancy. However, brake booster failure in older cars can cause the engine to run lean due to inadequate gasoline in the cylinder.
