Brake Wheel Cylinders on the 2018 Ford Fiesta: What You Need to Know

The 2018 Ford Fiesta does not use brake wheel cylinders as part of its braking system. This might surprise some, especially those familiar with older vehicles or certain brake setups where wheel cylinders play a key role. So, why is it that the 2018 Ford Fiesta doesn't have brake wheel cylinders and what does that mean for its braking system?

Brake wheel cylinders are typically found in drum brake systems. They are hydraulic components located inside each wheel's drum, responsible for pushing the brake shoes outward against the drum to create friction and slow the vehicle down. The design is straightforward and effective, especially for rear brakes on many cars produced before the widespread adoption of disc brakes.

However, the 2018 Ford Fiesta uses disc brakes on all four wheels, or at least disc brakes on the front wheels and drum brakes on the rear that use a self-energising mechanism with different components such as a brake caliper or shoes activated by a different method. Modern vehicles, like the 2018 Fiesta, often use disc brakes with calipers for the front wheels, and if drum brakes are present at the rear, they use more advanced mechanisms, sometimes incorporating electronic parking brakes or different servo processes rather than simple hydraulic wheel cylinders.

In the Fiesta's case, the rear drum brakes are operated by a different kind of hydraulic mechanism, often called a brake shoe actuator or a brake caliper piston in disc brake systems. As such, the traditional brake wheel cylinder, as seen in older classics or basic drum braking systems, is not part of the 2018 Fiesta's braking setup.

This shift away from brake wheel cylinders largely boils down to advancements in braking technology. Disc brakes provide better heat dissipation, more consistent braking performance, and generally require less maintenance than drum brakes with wheel cylinders. For safety, performance, and ease of service, carmakers like Ford have focused their designs accordingly, opting for disc brakes at the front and more sophisticated systems at the rear.

Because there are no brake wheel cylinders in the 2018 Fiesta, there is no need to check or maintain these components during servicing. Instead, brake system maintenance will focus on other parts such as brake pads, discs, calipers, brake fluid, and potentially the brake shoes and drum if the rear brakes are drum-type. It's a more straightforward and reliable setup overall.

For owners of the 2018 Ford Fiesta, understanding this distinction helps avoid confusion when reading vehicle manuals or trying to identify brake components. If a mechanic or parts website mentions brake wheel cylinders for a 2018 Fiesta, it's either referring to a similar part by mistake or discussing older models that did use these components.

Regular brake checks for the 2018 Fiesta should still include inspecting the brake pads and discs for wear, ensuring the brake fluid is clean and topped up, and checking the overall operation and responsiveness of the brake system. Any squealing, grinding, or reduced stopping power should prompt an immediate inspection. Since there are no brake wheel cylinders, those potential issues won't be related to leaking or faulty wheel cylinders but could rather be a sign of worn pads, damaged discs or caliper issues.

So, if someone needs parts or is considering servicing their 2018 Ford Fiesta's brakes, they should look for disc brake components at the front and corresponding rear brake parts depending on the exact model variant. Replacement of brake parts will hinge generally on the wear indicators on pads and discs rather than calls for new wheel cylinders.

All up, the 2018 Ford Fiesta benefits from modern brake engineering that does away with traditional brake wheel cylinders to provide safer, more reliable, and easier-to-maintain braking. Drivers can expect solid performance from their braking system as long as they keep up with the usual checks and maintenance like fluid changes, pad replacements, and disc inspections.
