The Pontiac Sunfire utilizes a standard braking system consisting of disc brakes at the front and either disc or drum brakes at the rear. The system relies on friction between brake pads and rotors (or drums) to slow and stop the vehicle, with brake fluid transferring pressure from the brake pedal to the braking mechanism.

The Pontiac Sunfire typically features disc brakes on the front wheels. These consist of a brake rotor (a metal disc) that rotates with the wheel, and brake pads that are pressed against the rotor to create friction.
The caliper houses the brake pads and applies pressure to them when the brake pedal is depressed.
When you press the brake pedal, the master cylinder sends pressurized brake fluid to the calipers, forcing the brake pads against the rotors.
Depending on the specific model year and configuration, the Pontiac Sunfire may have either disc or drum brakes on the rear wheels.
If drum brakes are present, they utilize brake shoes that press against the inner surface of a rotating drum.
In drum brakes, the wheel cylinder pushes the brake shoes outward against the drum.
These are the friction material that wears down over time and needs to be replaced.
These can also wear down and may need to be resurfaced or replaced.
Brake lines carry brake fluid to the calipers and wheel cylinders. They can corrode and leak over time and may need replacement.
The master cylinder is a critical component that can fail and require replacement.
Some Pontiac Sunfires may be equipped with an Anti-lock Braking System (ABS) which can affect brake bleeding procedures.
