The construction of brake system
Master Cylinder

Master Cylinder The master cylinder is located in the engine compartment on the firewall, directly in front of the driver’s seat. A typical master cylinder is actually two completely separate master cylinders in one housing, each handling two wheels. This way if one side fails, you will still be able to stop the car. The brake warning light on the dash will light if either side fails, alerting you to the problem. Master cylinders have become very reliable and rarely malfunction; however, the most common problem that they experience is an internal leak. This will cause the brake pedal to slowly sink to the floor when your foot applies steady pressure. Letting go of the pedal and immediately stepping on it again brings the pedal back to normal height.

Brake Fluid

Brake fluid is a special oil that has specific properties. It is designed to withstand cold temperatures without thickening as well as very high temperatures without boiling. (If the brake fluid should boil, it will cause you to have a spongy pedal and the car will be hard to stop.) Brake fluid must meet standards that are set by the Department of Transportation (DOT). The current standard is DOT-3, which has a boiling point of 460 F. But check your owners manual to see what your vehicle manufacturer recommends.

The brake fluid reservoir is on top of the master cylinder. Most cars today have a transparent reservoir so that you can see the level without opening the cover. The brake fluid level will drop slightly as the brake pads wear. This is a normal condition and no cause for concern. If the level drops noticeably over a short period of time or goes down to about two thirds full, have your brakes checked as soon as possible. Keep the reservoir covered except for the amount of time you need to fill it and never leave a can of brake fluid uncovered. Brake fluid must maintain a high boiling point. Exposure to air will cause the fluid to absorb moisture, which will lower that boiling point.
NEVER PUT ANYTHING BUT APPROVED BRAKE FLUID IN YOUR BRAKES. ANYTHING ELSE CAN CAUSE SUDDEN BRAKE FAILURE! Any other type of oil or other fluid will react with the brake fluid and very quickly destroy the rubber seals in the brake system causing brake failure.

Brake Lines

The brake fluid travels from the master cylinder to the wheels through a series of steel tubes and reinforced rubber hoses. Rubber hoses are used only in places that require flexibility, such as at the front wheels, which move up and down as well as steer. The rest of the system uses non-corrosive seamless steel tubing with special fittings at all attachment points. If a steel line requires a repair, the best procedure is to replace the complete line. If this is not practical, a line can be repaired using special splice fittings that are made for brake system repair. You must never use brass “compression” fittings or copper tubing to repair a brake system. They are dangerous and illegal.

Other Components in the Hydraulic System

Proportioning valve or Equalizer Valve
These valves are mounted between the master cylinder and the rear wheels. They are designed to adjust the pressure between the front and rear brakes depending on how hard you are stopping. The shorter you stop, the more of the vehicle’s weight is transferred to the front wheels, in some cases, causing the rear to lift and the front to dive. These valves are designed to direct more pressure to the front and less pressure to the rear the harder you stop. This minimizes the chance of premature lockup at the rear wheels.

Pressure Differential Valve
This valve is usually mounted just below the master cylinder and is responsible for turning the brake warning light on when it detects a malfunction. It measures the pressure from the two sections of the master cylinder and compares them. Since it is mounted ahead of the proportioning or equalizer valve, the two pressures it detects should be equal. If it detects a difference, it means that there is probably a brake fluid leak somewhere in the system.
Combination Valve Combination Valve
The Combination valve is simply a proportioning valve and a pressure differential valve that is combined into one unit.

Electronic Brake Force Distribution
Newer cars use the anti-lock brake hardware and the on board computer to replace these proportioning valve systems with a system called Electronic Brake force Distribution (EBD) in order to distribute the exact amount of pressure at each wheel to insure a balanced brake system.

Why is my Brake Disk Rotor Squeaking?

Unpleasant noises make us uncomfortable. Squeaky brakes are not an exception. There are ways in which you can avoid these dreadful noises that occur when driving. However, basic knowledge of brakes and how they function. This article will give you the answer to this disturbing question.

Is Brake Disk Rotor Squeaking Dangerous?

There are many causes of brake squeaking. Each cause determines how dangerous the squeaking can be.

Below are the reasons why brake disk rotor squeaks;

  • When brake parts are loose, squeaking noise is inevitable.

When loose, brakes components vibrate, rubbing against each other, consequently producing loud uncomfortable squeaking noise.

  • Brake pads are always rubbing against the rotor.

When they wear out, it exposes a metal indicator that scratches the rotor or the disk. Therefore, the squeaking noise serves as an indication of worn down brake pads.

This noise helps you avoid complete wear down of your car’s brake pads, hence you have them changed in time.

This noise is only heard when your limb is off the brake pedal.

In other cases, the rotor, drums, or other brake parts wear out, hence, they need to be checked by a professional mechanic.

  • Wet weather.

When you are driving during the extremely cold days, the rotor collects moisture. However, noises caused by atmospheric conditions don’t last long.

When the car heats up, the moisture evaporates, hence the squeaking disappears. Leaving your car outside during a snowy or rainy night will cause a buildup of snow or moisture around the brake parts.

The braking system will be permanently damaged if the car is left over a long period of time without being driven.

This will produce very loud and disturbing squeaking. Such a brake need to be changed.

  • Tiny foreign objects such as sand and sand will affect the normal functioning of the brake.

Excess friction will cause the brakes to produce the awful noise. This noise can be eliminated by having the brake cleaned and lubricated. This noise can be avoided by constant repairs and lubrication.

  • Having a heavy load on your trunk exerts pressure on the braking system.  The weight causes heating and swelling of brake parts. This causes extra friction which causes squeaking.
  • Hard brake pads are gaining popularity. However, their downside is that they tend to produce loud noise as compared to their softer counterparts.

Squeaking caused by the type of a brake pad is completely harmless.

  • Driving downhill requires constant breaking. This strain causes overheating, hence squeaking.
  • For the smooth functioning of brake parts, they need to be well lubricated once in a while. Do not leave them to dry so much, as it causes squeaking. This is common in cars without anti-rattle hardware between the brake pad and the brake caliper.
  • Metal flakes in cheap brake pads are usually large. They scratch the rotor causing squeaking. They also cause speedy damage to the rotor. Avoid cheap brake pads in order to save money.

Are squeaking Brake dangerous?

Brake disc rotor squeaking is an indication that something is wrong with the brake. Every kind of squeaking should be taken with seriousness.

Some squeakings are totally harmless, especially if they only happen in the mornings, and for a short while.

However, if squeaking is disturbingly loud, and does not disappear with time, you should take your car to a mechanic for servicing.

Solutions the Squeaking Brake Rotors

There are plenty of “solutions” in the market. You will find all sorts of “products” in the supermarket shelves promising to “kill” the noise.

Most of these “solutions” are not solutions as they promise. Be cautious whenever you opt for those “solutions”. They may cause long-term harm to your brake.

The only way to safely stop brake squeaking is by fixing the problem causing the noise.

The list below shows ways in which you can stop the squeaking.

  • Change the low quality brake pad with a better quality brake pad.

Most, if not all, cheap brake pads contain large metal flakes. This flake lowers the quality of the brake pad.

The flakes damage the rotor and cause the brake pad to wear out quickly.

Replacing such a brake pad with a high quality brake pad will help deal with unnecessary squeaking caused by low quality brake pads.



  • Use lubricant: Friction causes brake parts to dry up.

This consequently causes squeaking. Use a lubricant to do away with this noise. The process is easy and does not require a mechanic’s attention.

  • Constant servicing ensures that all your car parts are in good condition.

The brake is not an exception. This will help diagnose any braking problem early enough before the squeaking starts.

A brake specialist (mechanic) will identify any loose parts and fix it.

Loose brakes are dangerous, they will not serve their purpose when you need them most. The outcome may be fatal.

The Cost of Squeaky Brakes

There is no fixed rate of fixing squeaky brakes.

The cost will be dependent on various factors.

When limited labor and equipment are required, the cost will be relatively cheap.

The complexity of labor raises the cost.

In America, the range of brake job starts from $150 to $650. The price is higher when parts such as rotor and brake pads need to be changed. However, you can save a lot of you decide on having them resurfaced.

Brake job takes a relatively short time. A maximum of 2 hours is needed to have your brake fixed.

However, resurfacing will take longer, and you may require to look for an alternative means of transport.


It is obvious you want noise-free driving. You want to concentrate on the wheels and the road as you drive.

Brake disc rotor squeaking makes your journey stressful and uncomfortable.

That discomfort can make you have an unnecessary accident due to panic. But with the above knowledge, you will be able to diagnose the problem and take the necessary measures.

Now you are aware of your brake and what causes squeaking. Keep it lubricated and in good condition for a smooth ride.
