Signs of a Failing Brake Master Cylinder

The brake master cylinder is the heart of your vehicle’s braking system.brake master cylinder It turns the force exerted on the brake pedal into hydraulic pressure, which then presses the brake calipers against the rotors to slow down and stop your car. It’s an essential part of the system, so when it starts to fail you need to know what to look out for so that you can get it fixed promptly. At Dennis Road Automotive in Dallas, TX, we’re here to help you learn the signs of a failing master cylinder so that you can be aware and safe on the road.

How a Brake Master Cylinder Works

Your master cylinder has a bore inside of it which houses the pistons, with each of these two circuits representing one side of the vehicle’s braking system. When you depress the brake pedal, it pushes against the piston in the first circuit, and this creates hydraulic pressure to press the calipers against the rotors. The second piston in the master cylinder also experiences pressure as the force is applied, and this forces the brake fluid back through the lines to the reservoir.

When a master cylinder has a leak in either of these circuits, it will lose pressure and you’ll experience a loss of braking power. You may even notice a small puddle of brake fluid under your car. Some vehicles will also have a warning light that comes on when the hydraulic pressure in the brake system drops below normal levels.

A spongy or stuck brake pedal is another common sign of a failing master cylinder. This occurs when the seals in the cylinder are worn down, which leads to a lack of hydraulic pressure. This can also lead to the brakes becoming more difficult to control.

You might also notice that it takes longer than usual for the pedal to return to its original position after pressing it. Again, this is due to the weakened seals in the cylinder and it’s an indication that you should have the master cylinder replaced as soon as possible.

It’s important to check the brake fluid level regularly and replace it when needed to ensure your master cylinder is working properly. When this component begins to wear out, it can begin leaking and creating problems throughout the entire braking system.
