Brake Wheel Cylinders on the 2019 Ford Focus: What You Need to Know

If you're looking into the brake system of a 2019 Ford Focus, it's important to understand whether brake wheel cylinders play a role in this particular model. Brake wheel cylinders are traditionally found in drum brake setups, where they serve a crucial function. However, the 2019 Ford Focus generally does not use brake wheel cylinders as part of its braking system. Here's why.

The 2019 Ford Focus primarily comes equipped with disc brakes on the front wheels and disc or sometimes drum brakes on the rear wheels, depending on the specific trim or market. But here's the catch: Ford Focus models from this era typically use disc brakes on all wheels in many markets, especially in higher trim levels or sportier variants. When drum brakes are fitted to the rear, they do indeed rely on brake wheel cylinders. However, newer vehicles like the 2019 Focus are increasingly moving towards all-disc brake systems due to their superior performance and easier maintenance.

So, if the 2019 Ford Focus you're checking out has disc brakes all around, it won't use brake wheel cylinders at all. Disc brakes operate with calipers and brake pads instead of the drum brake's shoes and hydraulic wheel cylinders. On the other hand, if your particular model or market spec includes rear drum brakes, then brake wheel cylinders will be inside those drums, and they're crucial to making the brakes work.

Why are brake wheel cylinders not always used on newer cars like the 2019 Focus? Drum brakes have been slowly phased out because disc brakes offer better stopping power, less fading under heavy use, and simpler maintenance when it comes to pads and rotors. Disc brakes also dissipate heat more efficiently, which helps prevent brake fade and extends the life of the brake components. As a result, many modern compact cars, the Focus included, favour disc brakes on all four wheels where possible, eliminating the need for brake wheel cylinders completely.

However, if you find a variant of the 2019 Ford Focus equipped with rear drum brakes, knowing about brake wheel cylinders is still useful. Here's a casual take on what these parts do and how to look after them as part of your vehicle's brake system maintenance.

Brake wheel cylinders are small hydraulic pistons tucked inside the rear drum brakes. When you press the brake pedal, brake fluid is forced into these cylinders, which pushes the pistons outward. This action forces the brake shoes against the drum's inner surface, creating friction that slows the wheel down. Essentially, brake wheel cylinders convert hydraulic pressure into mechanical force to engage the brakes.

Over time, brake wheel cylinders can wear out or start leaking brake fluid, which obviously isn't ideal. This can cause a drop in brake fluid level, a spongy brake pedal, or uneven braking. Given how important brakes are for safety, keeping these parts in good nick is super important.

Brake wheel cylinders are pressure-sealed with rubber boots and contain pistons that slide to apply the brake shoes smoothly. With repeated use, these rubber seals can dry out, crack or perish, causing leaks or sticking of the pistons. Corrosion on the cylinder bore or pistons can cause the cylinder to fail as well.

So, if your 2019 Ford Focus has rear drum brakes, it is worth including brake wheel cylinder inspection and maintenance as part of your routine servicing. Here are some handy tips for that:

• During brake servicing, remove the brake drum to visually inspect the wheel cylinder for any signs of brake fluid leaks or damage.
• Check the rubber boots and seals on the cylinders for cracks, brittleness or other degradation.
• If the wheel cylinder is leaking or the pistons bind, replace it rather than attempt a repair. Replacement parts for Ford Focus wheel cylinders are readily available and not too pricey.
• Brake fluid should be replaced regularly as per Ford's recommended service intervals. Fresh brake fluid helps protect the wheel cylinders and other brake components from corrosion and moisture build-up.
• When replacing brake shoes or drums, it's good practice to also service or replace the wheel cylinders to avoid trouble down the track.

Taking care of the brake wheel cylinders means your rear drum brakes will function reliably, providing balanced braking performance and keeping you safe on the road.

In short, if you're working on a 2019 Ford Focus that features drum brakes in the rear, brake wheel cylinders are an essential part of the brake system. Although many modern Focus models have all-disc brakes and do not use wheel cylinders, those with drum brakes need regular check-ups to avoid brake issues. Proper servicing and replacement when necessary will help maintain smooth, effective braking every time you hit the pedal.
