Don’t worry if you just checked your car and now you feel spongy brake pedal after bleeding. This has happened to other people too. People often have this problem, which can many reasons.
If you feel spongy brake pedal after bleeding and it feels soft, it usually means that the job wasn’t done right; either there’s a leak of brake fluid or more air is stuck in the brake system. Make sure there is enough fluid in the master cylinder. If there isn’t enough fluid, the cylinder will pull air into the system.
What to do with Spongy Brake pedal after bleeding?
A car’s brakes are there to stop or slow it down. Friction brakes and regenerative brakes are the two types of brakes.
In order for friction brakes to work, pads or shoes must press against the wheels or drums. The wheels stop or slow down because of the friction.
The kinetic energy of the vehicle capture by regenerative brakes and turn into electrical energy that can power the electric motor of the vehicle. Most of the time, hybrid and electric cars use regenerative brakes.
The Way Friction Brakes Work
In order for friction brakes to work, pads or shoes must press against the wheels or drums. The wheels stop or slow down because of the friction.
Many people use disc brakes, which are a type of friction stop. A rotor connected to the wheel of a disc brake. A caliper connected to the frame, holds the brake pads in place.
The caliper presses the pads against the rotor. When the stop pedal is pressed down. This makes the pad and the rotor rub against each other, which slows down or stops the wheel.
Because they let heat escape better and shorten stopping distances, disc brakes work better than drum brakes. On the other hand, they cost more and need more upkeep than drum brakes.
Why do brakes need to be bled?
Bleeding the brakes is an important part of keeping a car’s brakes in good shape. Bodies of air can get into brake fluid over time. There are air bubbles in the brake button that can make spongy brake pedal after bleeding, when you press it, which can make the brakes less effective.
By bleeding the brakes, these air bubbles remove from the system, and the brakes will work properly again.
How often should your brakes be bled? How much it costs relies on how often you drive and how hard you work on your car. Bleeding the brakes every two to three years is enough for most drivers.
If you live in a hilly area or often drive in stop-and-go traffic, you may need to bleed the brakes more often.
How Brakes That Preserve Power Work
The regenerative brakes capture kinetic energy of the vehicle and turn it into electrical energy that can power the electric motor of the vehicle. Most of the time, hybrid and electric cars use regenerative brakes.
When you step on the stop pedal, the regenerative brakes start to slow the wheels down by turning their motion into electricity.
The electricity is then saved in a capacitor or battery. When the driver speeds up, the electric motor of the car gets power by the saved electrical energy.
When you put on the brakes, regenerative brakes are better than friction brakes. Because they recover some of the energy that would waste as heat. But they cost more and are harder to use than friction brakes.
They still have brake discs and pads, but they also have sensors, controllers, and other computer parts that need to be taken care of. Because of this, it is important to keep up with the maintenance plan your car’s maker gives you.
Do Regenerative Brakes Need to Bleed?
It is true that regenerative brakes need to be cleaned. Simple brake parts like pads, discs, and pistons are still made. But they also have other electrical parts that can make the system fill with air bubbles.
Because of this, it is important to keep up with the maintenance plan your car’s maker gives you. This will make sure that your regenerative stopping system works well and that your brakes are in good shape and you wont feel spongy brake pedal after bleeding.
What cause spongy brake pedal after bleeding?
If their is a spongy brake pedal after bleeding, there are a few things that could be wrong. An air bubble in the brake fluid is the most usual reason. By bleeding the brakes, these air bubbles are removed from the system, and the brakes work properly again.
A leak in the brake system is another reason that could be happening. If there is a break, air can get into the system and make a spongy brake pedal after bleeding. A skilled mechanic can look for leaks and fix them if they find any.
Last but not least, the master cylinder might not be set up correctly. The brake fluid flows to the brakes through the master cylinder.
It can make the pedal feel soft or squishy if it is not set up correctly. The master cylinder can be checked by a trained mechanic and fixed if needed.
How do I get rid of air bubbles responsible for spongy brake pedal after bleeding?
Bleeding the brakes is the best way to get rid of air bubbles in the brake fluid. This process cleans the system and adds new fluid. It also gets rid of any air bubble that causes spongy brake pedal after bleeding.
Someone will have to help you bleed the brakes. There needs to be someone in the car to press the brake pedal while the other person pulls the brakes on each wheel. You should have a lot of old rags or paper towels on hand because the process can get messy.
After bleeding the brakes, you should check the master cylinder fluid level and add more fluid if needed.
How can I tell if I need to bleed my brakes?
There are a few clues that your brakes might need to be cleaned. Most of the time, the stop pedal is soft or spongy. Blobs of air in the brake fluid can make this happen.
If your brakes feel like they’re not working as well as they should, that’s another sign that they might need to be cleaned. This might happen if brake dust or other dust gets stuck in the system.
Finally, if you press down on the brake pedal and hear a hissing sound, this could mean that there is a leak in the system. A skilled mechanic can look for leaks and fix them if they find any.
How to Find Leaks in Brake Fluid?
There are a few ways to find brake fluid leaks. One thing to do is to check the master cylinder’s oil level. The fact that it is low could mean that there is a leak.
Look for signs of fluid on the ground where your car is stopped as another way to find leaks. If you see a pool of fluid or marks on the ground, it could mean that there is a leak.
Finally, if you press down on the brake pedal and hear a hissing sound, this could also be a sign of a leak. A skilled mechanic can look for leaks and fix them if they find any.
How to Do Your Own Check of the Master Cylinder?
It’s not hard to check the master cylinder on your own. A clean rag, a small mirror, and a flashlight are some of the things you will need. Open the hood and look for the brake fluid tank while the engine is off.
The tank is usually on the driver’s side of the car, close to the firewall. Take off the reservoir’s lid and use the clean rag to wipe off any dirt or other things that might be inside.
Next, look inside the tank with the small mirror. It’s possible that your master cylinder is broken and needs to be replaced if you see any brake fluid leaks.

FAQs
For how long does a Master Cylinder last?
An important part of your car’s stopping system is the master cylinder, which is what gives the brakes their hydraulic pressure.
When you step on the brake pedal, fluid pushes into the brakes from the master cylinder. The brakes then use the pressure to stop the wheels.
How long does a master cylinder really last? It really depends on a lot of things, like the type and make of car, how you drive, and how often you service.
Most master cylinders will last between 60,000 and 200,000 miles, though. There are, of course, always exceptions to this rule. Some may last a lot longer, while others may need to be changed more quickly.
How Often Should You Bleed Your Brakes?
Regularly bleeding your brakes will help your master cylinder last as long as possible. If air got into the system, this helps get rid of it. Air can be bad for the system. Generally, you should bleed your brakes about once a year.
