Chevrolet P30 Van Brake Booster

Finding the Causes behind Common Chevrolet P30 Van Brake Booster Problems

Majority of modern cars and trucks use the brake booster technology. The Chevrolet P30 Van brake booster works with the brake pads and the brake discs to increase the force needed to put your vehicle to a stop. With its vacuum diaphragms, the brake booster is able to increase the amount of pressure that you apply when you step on the pedal. But when you abuse your brakes, you put a lot of stress on the boosters, which makes them weak. Brake problems may begin to manifest. In troubleshooting such issues, you have to be keen enough to know what is actually going on. Here are some tips that you can follow to find the culprits behind booster troubles.

Brake booster fluid contamination

Contamination occurs when the rear part of the master cylinder cracks or breaks. If you look closely, the master cylinder has a tiny pin shaft and a seal that contains the brake fluid. You'll know that the seal is broken when you see leaks at the bottom of the brake booster housing. You will also notice that the rubber diaphragms in the inner housing begin to melt and warp. Most of these symptoms are hard to find. That's why you have to look closer to the boosters to identify the problem.

Hard brake pedal

If your brake pedal requires you to step on it a bit harder, you might be having problems with the brake boosters. To verify that this problem exists, try pumping the brake for a few times while the engine is off. Observe the pedal if it will move down a bit further. A well-functioning booster will pull the pedal down. If it doesn't move at all, it means that the booster is severely damaged.

Hose leaks

When the brake pedal feels hard to step on, it's possible that there's not enough pressure in the vacuum. This happens when the brake hoses are leaking. To check the hose for cracks, you have to disconnect them from the brake booster. Do this while the engine is off. Remove the plastic valve from the hose, and then try to blow into the valve. The air should flow in one direction only. You have to replace it if you notice that the air passes on both sides.

  • How to Make Your Chevrolet P30 Van Brake Booster Last

    The sure-fire way to lower your automotive expenses is to maintain the key components of your vehicle. Through this, you'll be able to save up a handful of cash from unnecessary car repairs and replacements. The Chevrolet P30 Van brake booster is considered as one of the most expensive parts in your vehicle. It needs utmost care and attention, so it won't get damaged easily. Here are some money-saving maintenance tips that you should follow if you want your brake booster to last:

    • Regular inspection is a must.
    • Don't neglect your brake boosters. Don't wait for the signs of booster failure to manifest, before you start paying attention to it. Periodic maintenance inspection is important to detect early symptoms of a broken booster. What you need to do is to get a calendar and mark the specific dates of your inspection. This way, you won't miss your schedule.
    • Vacuum filter replacement is necessary.
    • Some boosters include a small vacuum filter built inside the hose. This filter is responsible for removing harmful debris that can clog the brake lines and the booster. Over time, this filter gets congested with contaminants. Make sure to replace this component when it's been used for a while. This will keep your booster protected from pollutants.
    • Extra caution is important during the installation.
    • The brake booster consists of sensitive components, so you have to be very careful during the installation process. You should handle the booster, as well as the other relevant components such as the brake master cylinder, with care. The brake line is also prone to damage, that's why you should not put any pressure on it while trying to detach the booster from the master cylinder during the installation.
    • Inspection of the other brake-related parts is vital.
    • Installing a new brake booster will become useless if the other brake components are defective as well. A leak in the master cylinder, for instance, can cause premature failure to the newly-installed brake booster. It is necessary to ensure the proper functioning of the brake lines and the brake hoses too to prevent costly repairs in the future.
