Spongy brakes after bleeding – what to do

When you brake your car, you expect the pedal to feel firm and solid. If it feels spongy or soft, it could be a sign that there is a problem with the brakes. In this blog post, we’ll describe what it’s like to drive a car with spongy brakes and discuss some possible causes. We’ll also provide information on how to fix this issue and explain why it’s important to do so.

Let’s take a look!

What is brake bleeding?

Bleeding a car’s brakes is an essential maintenance task that must be performed regularly. It involves removing air from the brake lines and refilling with new, clean brake fluid. This helps ensure that the brakes work correctly and effectively, giving you greater control over the vehicle.

The reason it’s important to bleed a car’s brakes is because air can become trapped in the brake lines over time, leading to reduced braking power or even complete failure of the brakes. Bleeding removes this air and ensures that your brake system works as intended.

How are brakes bled?

There are several methods used to bleed the brakes depending on the make, model and year of manufacture of your vehicle. The most common method is to use a brake bleed kit that includes a vacuum pump and a container to collect any old fluid. This allows you to easily bleed the brakes by pumping the pump and allowing fresh brake fluid to exit the system.

Another method is to use an assistant who will press the brake pedal as you open and close the valves in sequence, allowing air and old fluid to escape. This can be done with two people or with a single person doing both jobs simultaneously, making it a little more difficult but still possible.

Some newer cars may have electronic systems that require special bleeding tools, including individual vacuum pumps that can do all the work on their own without assistance. With these types of systems, it is important to carefully follow the instructions provided by the manufacturer to ensure that everything is done correctly.

How often do brakes need to be bled?

It is recommended to bleed your car’s brakes every two years or whenever there is a problem with braking performance. This can be done by yourself or by taking it to a professional mechanic. If you decide to do it yourself, make sure you have all the necessary tools and safety equipment before attempting any work.

How are the spongy/soft brakes?

When you have soft or spongy brakes on your car, it can be a very unsettling experience. Driving becomes an unpredictable endeavor as the brakes may not respond as quickly or efficiently as expected. It may even seem like there is no brake at all.

When braking, the pedal will likely go down further than normal and will require greater pressure to stop the vehicle. You may also feel a little sag or bounce when you press the brake pedal, which indicates that something is wrong with your brakes. In some cases, you may hear a hissing sound coming from close to the pedal as air escapes from somewhere in the system.

This type of problem can make it difficult to predict how long the car will take to stop, especially in dangerous situations.

Why can brakes still feel spongy after bleeding?

Brakes that feel spongy after being bled can be very frustrating. There are several possible causes for this problem, including air bubbles still in the system, a leak in the brake system, or problems with the master cylinder.

bad bleeding techniques

Spongy bridles can sometimes be the result of poor bleeding techniques. If you use improper technique or tool when bleeding the brakes, it can cause air to be trapped in the system, which will reduce braking efficiency and cause a spongy feeling.

Stagnant air in the lines

Air bubbles trapped in the brake lines can make your brakes feel spongy when pressed. If you’ve recently bled your brakes and you still have a spongy feeling, it’s possible that there’s still air trapped in the lines. To correct this problem, you will need to rebleed the brakes until all the air has been removed from the system. This can lead to multiple bleeds depending on how much air was originally present in the lines.

Leaks in the System

Another potential cause of spongy brakes is a leak in the brake system. This could be due to worn rubber seals and other components that become brittle over time. If you suspect this to be the case, it would be wise to check for visible leaks, as well as inspect all seals and gaskets for signs of wear or deterioration.

Master cylinder

Finally, if your brakes are still spongy after bleeding them, it could be due to a problem with your vehicle’s master cylinder. The master cylinder supplies hydraulic pressure to the brake system, so if it is not working properly there will not be enough pressure to fully engage the brakes when pressed. In that case, you will need to replace or rebuild the master cylinder to restore normal brake pressure.

Is it safe to continue driving a car with spongy brakes?

No, it is not recommended to drive a car with spongy brakes. The problem can get worse over time, making it increasingly difficult to stop the vehicle as expected. This can be especially dangerous in emergency situations where quick response and precise braking are essential to keep you safe.

Therefore, if your brakes feel spongy after being bled, you should investigate the problem immediately and resolve any underlying issues as soon as possible. This will help ensure your vehicle remains safe while on the road.

Should You Try Fixing Spongy Brakes Or See A Professional?

It’s possible to fix spongy bridles on your own, but it may be wise to consult a professional if you’re not sure what the underlying problem might be. A professional mechanic will have the knowledge and experience necessary to properly diagnose and repair any brake problems.

They will also have access to specialized tools and equipment that can make the job easier.

In conclusion, soft or spongy brakes can pose a major safety risk due to reduced braking power due to air bubbles in the lines or faulty system components. Therefore, it is important to resolve this issue as soon as possible by bleeding or replacing parts depending on the cause. Consult a professional for accurate diagnosis and repair if necessary.
