Brake Wheel Cylinders on the 2018 Subaru Forester: What You Need to Know

When it comes to the 2018 Subaru Forester and its braking system, understanding whether the vehicle uses brake wheel cylinders is key to keeping it in top shape. In this case, the 2018 Forester does not feature traditional brake wheel cylinders. This might come as a surprise to some, especially those familiar with older vehicles or certain brake system designs, so let's break down why that is and what that means for Forester owners.

Brake wheel cylinders are components typically found in drum brake setups. They serve an important role by pushing the brake shoes out against the drum when the brake pedal is applied. This pressure creates the friction needed to slow down or stop the vehicle. Essentially, brake wheel cylinders convert hydraulic pressure from the master cylinder into mechanical force, helping to engage the brakes at each wheel.

Now the 2018 Subaru Forester is equipped with disc brakes on all four wheels, which means it uses brake calipers instead of brake wheel cylinders. Disc brakes are the more modern braking system and work slightly differently to drum brakes. Instead of brake shoes and wheel cylinders, disc brakes have brake pads and calipers. When the brake pedal is pressed, hydraulic fluid pushes pistons within the caliper, which in turn squeeze the brake pads against the metal rotor attached to the wheel. This action slows the vehicle down with excellent stopping power and improved heat dissipation compared to drum brakes.

The reason drum brakes with wheel cylinders are less common on modern vehicles like the Forester is because disc brakes deliver better performance, especially under heavy or high-speed braking conditions. Disc brakes tend to be more reliable in wet conditions, less prone to brake fade, and easier to inspect and maintain. For these reasons, Subaru and many other manufacturers have transitioned to all-wheel disc brakes on their latest models.

So what does this mean for Forester drivers in practical terms? Since there are no brake wheel cylinders to worry about, maintenance and servicing focus on the disc brake system components, mainly the brake pads, discs (rotors), and the calipers themselves. During routine brake servicing, it's vital to regularly inspect these parts for wear and tear. Brake pads wear down over time and need replacing when they reach their minimum thickness. The brake discs should be checked for signs of scoring, warping, or cracking, which can affect braking performance.

While brake wheel cylinders don't come into play on the Forester, it doesn't mean the brake system is maintenance free. Brake calipers, which effectively perform a similar function to the wheel cylinders, should be checked and serviced when needed. Caliper pistons can become sticky or seized, preventing proper brake pad movement. Brake fluid quality and level are also crucial, as degraded or contaminated fluid can lead to reduced braking efficiency and corrosion in the hydraulic system.

Regular brake fluid changes every two years or so (depending on driving conditions) help maintain the reliability and safety of the entire brake system. Always make sure to follow Subaru's recommended service intervals for brake inspections and fluid changes, as ignoring these can lead to bigger, costlier repairs down the track.

In short, although the 2018 Subaru Forester does not use brake wheel cylinders, the vehicle's braking system is built with modern disc brakes that require their own type of routine maintenance. Knowing what parts to monitor and replace will keep the Forester stopping safely and smoothly for many years.
