Porsche 944 Turbo Brake Booster

Problems of Porsche 944 Turbo Brake Booster and How to Fix Them

If you feel your Porsche 944 Turbo brake booster isn't working the way they should, then there's a reason to be concerned. Driving a Porsche 944 Turbo with a brake pedal that is hard to depress is dangerous for you and for the vehicles around you on the road regardless of the speed you are driving. While a brake going berserk because of a faulty brake booster isn't an everyday occurrence, it is important that you know how to diagnose and troubleshoot your brake booster in case it happens to your car.

The brake booster is leaking.

A problem most common to brake booster is vacuum leaks due to damaged or worn-out pistons or diaphragm, valve, seals, and rubber hose. When this happens, you still have your brake working, but with little or no assist from the power brakes, forcing you to apply more pressure to the brakes just to make the vehicle stop. To check for vacuum leaks, depress the brake pedal five times or until the brake is hard to depress. Start the engine with your foot still on the brake pedal. If the pedal goes down slightly after you start the engine, your brake booster is no longer working. Fix the problem by replacing the entire unit with a new or rebuilt brake booster.

The brake booster is producing whining noises.

When the vacuum line attached to the brake booster is punctured, it lets the air out and produces a whining noise every time you step on the brake pedal while driving. Replace the vacuum line to solve the problem and avoid damaging the brake booster.

The brake pedal is hard to depress and doesn't return.

This is the sign that your brake booster is out. Your brakes will still work, but you have to apply greater pressure to the pedal just to make your vehicle slow down or stop. Vehicle owners often say that they literally have to stand on the brake pedal or use two feet just to make the brakes bite. If you experience this, you should replace the brake booster right away.

  • Porsche 944 Turbo Brake Booster Maintenance Tips 04 March 2014

    A Porsche 944 Turbo brake booster, just like the brake boosters of other vehicles, is pretty reliable. It rarely fails and can sometimes outlive your car. It requires no maintenance, which makes it the most unnoticeable part of your brake system. Sometimes though, a brake booster leaks. When it does, you will feel it, literally. Without a brake booster, you have to depress the brake pedal harder than usual just to slow the vehicle down. If you're running at highway speed and have to stop, you have to stand on the pedal or use two feet just to get the bite you want. Unfortunately, no matter how hard to step on the brake pedal, sometimes it is not enough, which makes driving a Porsche 944 Turbo without a properly working brake booster a safety risk. To help keep the Porsche 944 Turbo brake booster working without a hitch, you can follow the following tips:

    • Watch out for signs of failure.
    • The brake booster is the heart of your Porsche's 'power brake' system and must be working all the time. If you feel that your brake starts to slip and your brake pedal becomes hard to depress, look for vacuum leak or fluid leak. Observe if there's a change in the resistance of the brake pedal. If you notice any irregularity, repair it immediately, change the brake booster with either new or rebuilt part, or go to an expert mechanic. The idea is to make sure that the issue is recognized and addressed right away before driving becomes dangerous.
    • Routinely check your brake booster when you wash your engine.
    • Fluid leaking between the booster and the brake master cylinder is a clear sign of a troubled brake booster. Other obvious signs are a puddle of oil directly below the brake booster and a low-level of brake fluid in the reservoir.
    • Always check if the vacuum is sealed.
    • Brake booster malfunction is often the result of vacuum leak. Listen if there's any whining or hissing noises when you release the brake pedal. If there is, the vacuum line is likely damaged.
