How does the brake system work on a Kia Optima?
At the most basic level, the brake system works by using the force that you apply to the brake pedal and converting it to hydraulic pressure (magnified by the engines vacuum at the master cylinder). This pressure is applied to the brake pads (or shoes if it’s drum brakes) and your Optima slows down.
Why are my brake pads squeaking on my Kia Optima?
Glazing hardens the contact surface of your pads, and diminishes their overall braking performance. Squeaking brakes are just a side effect of this condition. If you Kia Optima has glazed brake pads, they need to be replaced. There is supposed to be a small backing shim that goes between the brake pad and the caliper.
Why are the brakes squeaking on my EcoSport?
The most typical cause of squeaky brakes are the brake pads themselves, but there are other issues that can cause the noise as well. The good news is that brake pads are cheap.

What happens when your brake pedal goes to the floor?
This failure can create an intermittent brake pedal fade. Pumping the brakes can cause these seals to expand and may help the brake master start working again. When this failure occurs, the brake master cylinder must be replaced with a new unit.
What to do when your brake pads go to the floor?
If the reservoir is empty then either the front or rear brake pads need to be replaced or their is a leak somewhere in the brake system. Inspect for Brake System Leaks: Using a flashlight check the rear of the master cylinder where it bolts to the brake booster.
