If any of these issues are detected, immediate action should be taken to prevent further damage.
What to Check During an Inspection:
To prevent rust and corrosion, regularly clean the wheel cylinders and lubricate moving components. Use high-quality brake cleaner to remove any dirt, grease, or grime that may have accumulated. After cleaning, apply a small amount of lubrication to prevent friction and protect the internal parts of the cylinder.
3. Replacing Worn Seals
If the seals in the wheel cylinders are worn or damaged, they should be replaced as soon as possible. Seals are relatively inexpensive parts and can be easily replaced by a qualified mechanic.
How to Replace Seals:
In cases of severe damage, such as when the cylinder is rusted or cracked, it may need to be replaced entirely. Depending on the severity of the issue, repairing the cylinder could involve honing or replacing the cylinder bore. This requires specialized tools, so it’s often best to consult a mechanic or specialist if the damage is extensive.
When to Replace the Wheel Cylinder:
To keep your Fermac 650B in top condition and avoid problems with the rear wheel cylinders, consider the following preventative measures:
Maintaining the rear wheel cylinders on your Fermac 650B is an essential aspect of ensuring the machine’s performance, safety, and longevity. Regular inspections, proper cleaning, and timely seal replacements can significantly extend the life of the braking system and reduce the likelihood of unexpected repairs. By staying on top of these maintenance tasks, you can avoid the frustration and cost of major brake system failures and keep your equipment running smoothly for years to come.

One of the most common issues with wheel cylinders is leakage of brake fluid. This can occur if the seals inside the cylinder degrade or become damaged. Leaking brake fluid can lead to a drop in hydraulic pressure, causing poor braking performance and posing serious safety risks.
Symptoms of Leaking Wheel Cylinders:
- Reduced braking power: You might notice that the machine takes longer to stop or requires more effort on the brake pedal.
- Brake fluid loss: There will be visible fluid spots around the wheels, or you might notice a low brake fluid level in the reservoir.
- Soft or spongy brake pedal: This happens when air enters the brake lines due to the fluid leak.
Since the rear wheel cylinders are exposed to moisture, dirt, and grime from the environment, rust and corrosion can form over time. This not only weakens the cylinder but also makes it difficult for the components to move smoothly, leading to inefficient braking.
How Rust Affects the Wheel Cylinder:
- Seized components: Corrosion can cause the piston inside the cylinder to seize up, preventing it from moving properly.
- Inefficient braking: Rusted surfaces create friction, which can reduce the effectiveness of the brake system and cause uneven brake application.
The seals inside the rear wheel cylinders are designed to prevent fluid leaks and keep contaminants out. However, over time, these seals can become brittle and wear out. When this happens, the fluid pressure in the system decreases, leading to reduced braking effectiveness.
Signs of Worn Seals:
- Brake fluid leakage: This is the most direct indication that the seals are damaged or worn.
- Uneven braking: Worn seals can cause one side of the brake to apply more pressure than the other, leading to uneven braking and pulling to one side.
