What does a brake master cylinder do?

The master cylinder converts the mechanical force from your brake pedal into hydraulic pressure. This pressure is then sent through the brake lines to actuate the brakes and slow down your vehicle.

What are the signs of a failing brake master cylinder?

Common signs include a spongy or soft brake pedal, the brake pedal sinking to the floor, or a noticeable drop in brake fluid level. You might also experience reduced braking performance.

Does this master cylinder come with brake fluid?

This DFC brake master cylinder does not include brake fluid. You will need to purchase compatible brake fluid separately and ensure the system is properly bled after installation.

Product Details

DFC is known for making reliable replacement parts, and this brake master cylinder is no different. If you're working on a 2013 to 2015 Kia Optima and need to replace your master cylinder, this part is built to get your braking system back in working order.

A master cylinder is a key component in your car's braking system. It takes the force from your foot on the brake pedal and turns it into hydraulic pressure that forces the brake pads against the rotors, slowing your vehicle down. When it starts to fail, you might notice a spongy brake pedal, or your brake fluid level might drop. This DFC master cylinder is designed to be a direct fit for your Optima, making the replacement process straightforward.

This part is a direct replacement, meaning it's made to install just like the original equipment. Ensure you properly bleed your brake system after installation to remove any air and ensure optimal braking performance.
