How To Fix A Squeaky Brake Pedal

When your brake pedal goes soft or even disappears, it can be tricky to know what to do. Fortunately, you have us! Here are some tips to fix a squealing brake pedal. If needed, you can also replace the parts that make up your braking system.

Fortunately, most cars these days come with built-in sensors that warn you when it’s time to take action. For example, if there is a warning light for wheel slip, then your car will automatically apply pressure onto the brakes to prevent a skid.

This automatic braking helps in two ways. First, it adds safety because the vehicle is protecting itself by slowing down before something bad happens. Second, it gives you more time to react and avoid an accident.

However, due to friction between the wheels and the surface of the road, some of this energy gets lost as heat. This results in your car heating up and the fluid in the components changing state (for example, boiling).

When this occurs, hydraulic fluids become thicker and heavier which makes the pedals harder to push down. Because of this, the pedal may feel very mushy or even spongy and cannot generate much force.

Removing any kind of lubricant from inside the brake system can cause problems at the very least, but probably replacing the pistons and/or cylinders is out of the question. Therefore, trying to reduce the amount of drag caused by rolling resistance is crucial.

Check the brake fluid

A lot of people begin to feel their brakes are not working effectively when they notice a squeaking or grinding sound coming from them. This is usually caused by dry braking surfaces due to lack of fluid in the system.

Most cars these days have dual-circuit braking systems. There is an antilock braking (ABS) circuit that applies pressure to the wheels, and then there is a regular braking circuit that uses hydraulic pressure to apply friction to the wheel surface.

If you hear any kind of noise while using your ABS system, it may be because it has run out of fluid. When this happens, the system can’ll go into overdrive to compensate for the lack of hydraulic pressure, which will make the car more stable, but it will also mean that it takes longer to stop!

You should check your brake fluid level every once and a while to see if anything is low. Also, make sure that your pedal is depressed all the way down before checking so you do not mistake moisture for fluid.

Check the brake lines

One of the first things you should do if your vehicle is experiencing squealing brakes is check the brake lines. This can be done by using a multimeter or hand test tools.

If there are cracks, kinks, or pops in the line then it’s time to replace them. If the line looks slimy or dirty, they need to be replaced as well!

The hose that connects the master cylinder to the caliper may also look loose or stiff. You can have someone push down hard on the pedal while you inspect to see if this makes a difference.

A dry, tight friction fit between the brake fluid and the line will make the noise disappear. A wet, sloppy connection will produce more sound.

Check the brake shoes

The first thing we will do is check your brake shoe for wear. If they are worn down beyond the elastic limit, then they will no longer grip the wheel or drum very well.

This could be due to excessive pedal travel which stresses the shoe more, or poor quality brakes that lose friction as they heat up.

If you notice any kind of noise coming from under the car when braking, try pulling out the wheels and looking at the brake discs or drums with a torch to see if there’s anything stuck to them.

You may also want to clean the brakes as this can help restore lost friction, otherwise known as drag. Use some brake cleaner or ether (a fluid used in cars) and warm water to wash the parts.

Finally, make sure your foot is tight enough! We cannot stress this enough. A loose or too-loose sock or pant leg area can cause excess movement inside the pedal box.

Change the brake fluid

If your car is experiencing very squeaky brakes, it could be due to low braking friction caused by dry brake fluids. As drivers, we usually do not think about how our cars’ hydraulic systems work, but they are an integral part of how well your vehicle will stop.

When you apply pressure to the brakes, there is a fluid that comes out which helps create friction with the surface being braked. This fluid can become limited when your vehicle does not feel or perform like it should.

If you notice that your car is having more than normal amount of squeal when applying the brakes, it may be time for some changes. Changing the fluid in your brakes will fix this problem!

Tip: Make sure to never change the fluid yourself as doing so can cause serious injury or death. Have a professional do it for you.

What kind of brake fluid should you use?

A few brands of fluid that have been proven effective are DOT 9 (Avia-brand), Silica-based fluid such as Duralon or Calcium Sulphur Ester (CASE) fluid, and silicon fluid. These are all safe to use and will bring the same results.

The best fluid depends on what type of surfaces you will be stopping on and whether or not moisture is present.

Replace the brake pads

One of the most common causes for a squeaking or grinding braking pedal is bad brake pad material. If you are experiencing this, it is important to understand what kind of brakes your car has and which type of brake pad goes with it.

If you are looking to stop quickly, then average street level brake pads will usually suffice. However, if you want better performance, then upgrade!

It is very expensive to buy new brake pads every time there is noise, so try to determine when a replacement is needed first.

By replacing just the old brake pad, you can save money by buying new ones later.

Replace the brake lines

One of the first things that can cause your vehicle to have a squeaking or squealing pedal is dry brake lines. As we mentioned before, when air pressure in your brakes decreases, the fluid within the line becomes thinner.

As you apply foot pressure on the pedal, there are now less fluids between your feet and the metal parts of the brake system. This creates an uncomfortable feeling for the driver as well as corrosion of these components due to the loss of protective lubrication.

Since it takes several miles per hour for the vehicle to stop, this repeated stress can eventually lead to failure. If you notice any noises coming from under the car, make sure to check out the brake lines!

Properly replacing the brake lines will ensure that your vehicle does not suffer from premature malfunctioning of its braking systems. There are many places online where you can find instructions on how to do so.

Replace the brake shoes

One of the first things you will notice if your car makes a squealing noise when you apply pressure to the brakes is that the pedal is very hard to push down. This can be due to either defective brake pads or, more likely, faulty brake shoes!

If you are looking to fix this problem yourself, then it’s best to do so at night time as there won’t be too many people around. Also, make sure everything else is done for your vehicle before replacing the brake shoes, such as checking out the fluid level and cleaning the wheels and rotors.

To test whether or not the pistons are moving properly, use a piece of thin wire and pull up on the piston.

Run the brakes to see if they work properly

A vague “brakes feel rough” could be due to something many different things. Make sure your vehicle is at least slightly warm before checking the brake fluid, as it can cause the skin of the pedal to dry out which makes it feel tighter.

If you check the brake fluid and it looks normal, make sure that none of it has escaped through any holes in the reservoir or lines. If it seems like there isn’t enough fluid in the master cylinder, then try moving the lever up or down with your thumb to see if this adds more pressure.

If all these checks come back clear, then turn off the car, pull over somewhere safe, and apply pressure to the brake for several seconds. When you remove your foot, the pedal should return to its original position.
