Brake Wheel Cylinders on the 2012 Ford Ranger: What You Need to Know

The 2012 Ford Ranger is a popular ute in Australia, well-known for its reliability and rugged build. When it comes to the braking system of this model, it's important to understand the components involved, especially the role of brake wheel cylinders. However, the brake system on the 2012 Ford Ranger doesn't actually use traditional brake wheel cylinders, and here's why.

Brake wheel cylinders are a key component in drum brake systems. They sit inside the brake drum and push the brake shoes outwards to create the friction needed to slow the vehicle down. But the 2012 Ford Ranger is equipped with disc brakes on the front wheels and drum brakes at the rear. Even though it has rear drum brakes, this model employs a design where brake wheel cylinders are not the primary component operated in the braking mechanism.

Instead, the 2012 Ford Ranger uses a self-adjusting rear drum brake assembly that relies more on a central mechanism like a mechanical adjuster rather than traditional brake wheel cylinders. In modern drum brake setups, the role of pushing the brake shoes is typically managed by a single piston system integrated within the brake backing plate or the use of a different hydraulic actuator. This means that classic brake wheel cylinders, which are two small pistons pushing on the shoes from either side, are less relevant here.

So why have brake wheel cylinders fallen out of use on vehicles like the 2012 Ford Ranger? The answer lies in improved brake designs that offer better reliability, easier maintenance, and enhanced performance. Modern drum brakes benefit from fewer moving parts and more integrated solutions, reducing the likelihood of leaks and failures associated with traditional wheel cylinders.

For the 2012 Ford Ranger owner, servicing the rear drum brakes involves inspecting the brake shoes, springs, and the self-adjusting mechanism but does not require dealing with individual brake wheel cylinders. Instead, brake servicing focuses on:

• Checking the condition of brake shoes and replacing if worn
• Ensuring the brake drum surface is smooth and free of scoring
• Inspecting and lubricating the brake adjuster mechanism
• Checking the integrity of the hydraulic brake lines and wheel cylinders if fitted (on other drum brake designs)

Since the 2012 Ford Ranger's rear brakes do not rely on traditional brake wheel cylinders, maintenance is generally simpler. It mainly involves regular inspections as part of routine servicing and replacement of brake shoes and drums when they show signs of wear rather than rebuilding or replacing wheel cylinders.

It is worth noting that if the Ranger had used brake wheel cylinders, there would be a few key things to keep in mind for maintenance and replacement. Brake wheel cylinders are prone to corrosion and seal wear over time, which can cause brake fluid leaks and lead to a loss of braking efficiency. Typically, when a brake wheel cylinder starts to leak or feels spongy, replacement is necessary rather than attempting a repair because the internal components are difficult to service effectively.

Proper maintenance of brake wheel cylinders would include periodically checking for brake fluid leaks at the wheels, ensuring the brake shoes have good contact with the cylinders, and flushing the brake fluid system every couple of years to prevent moisture build-up which accelerates corrosion.

Overall, while brake wheel cylinders play an important role in some drum brake systems, the 2012 Ford Ranger's rear drum brakes utilise a more modern system that does not rely on traditional brake wheel cylinders. For owners, this means less fuss with wheel cylinder replacement and a focus on maintaining brake shoes, drums, and the self-adjusting mechanisms to keep the brakes working smoothly.

Stick to the recommended service intervals, keep an ear out for any unusual noises like squealing or grinding from the rear brakes, and have your brakes inspected regularly to ensure everything is in tip-top shape. It's all about making sure the Ranger stops as well as it goes whenever you're out on Aussie roads or tackling off-road adventures.
