Toyota 4Runner Power Brake Boosters

If you think of a vehicle's weight for a moment, you may wonder how it is possible that just a relatively small pressure applied on the brake pedal can slow down or stop tons of mass. The answer is a small metal box known as a brake booster, which contains a smart device that multiplies that pressure, transforming it into a strong and efficient force that can handle even the heaviest cars, trucks, or SUVs like your Toyota 4Runner. Depending on the car type and design, the brake booster can be hydraulic or vacuum-operated. The former utilizes the fluid pressure to boost the braking action, while the latter uses the pressure differential between the atmosphere and the partial vacuum created by the engine.

If greater effort is required to engage the brakes or there's a spongy pedal feel, there are chances that the brake booster requires a thorough check and, perhaps, a replacement. At our online store, we have a large selection of top-notch Toyota 4Runner brake boosters, carefully designed by top-ranked companies and solidly built to assist you in your braking action, whatever the situation.
