Merkur XR4TI Master Cylinder

Signs of a Problematic Merkur Xr4ti Master Cylinder and Tips on How to Verify Them

Driving safely is one of the major concerns of every driver on the road. To promote safety, most modern vehicles have a hydraulic pressure-operated brake master cylinder. Your Merkur Xr4ti master cylinder, for example, converts the mechanical force received by the brake pedal into hydraulic pressure. This pressure aids in stopping or slowing down the vehicle. Like any other car parts, the master cylinder may wear and get damaged over time. So here are a few tips on identifying if your master cylinder needs repair or replacement:

Brake pedal fade

When you have a bad master cylinder, the first thing you'll notice is that the pedal goes all the way down to the floor upon braking. Step on the brake and observe if the pedal continues to sink after you have released the brake. If it does, then there might be a hydraulic fluid leak in your master cylinder.

Non-returning pedal

This is the most noticeable sign of brake master cylinder damage. Test drive your car and try to step on the brake until it almost touches the floor. If the brake pedal doesn't return to its normal position, then this may indicate the need for a master cylinder replacement.

Decreased braking performance

A broken master cylinder leads to a reduced stopping power. This is because the pressure between the two cylinders is decreased, leading to an immense decrease in the pressure needed to stop the car. Moreover, you may find it unusual that your brakes take longer distance before they stop your vehicle completely. Once these symptoms start showing up, check your master cylinder immediately.

Brake fluid leaks

Crawl under your car. Check for signs of leaks directly underneath the master cylinder. A puddle or drops of brake fluid under your car can indicate a leaking master cylinder. To verify if the brake fluid puddle came from your master cylinder, inspect your master cylinder for any cracks or holes. You can also try removing the whole master cylinder from the brake system and checking for wear and damage. If you have confirmed that your master cylinder has gone bad, it's highly recommended that you repair or replace it immediately to prevent damaging the whole braking system.

  • Tricks and Tips to Keep Your Merkur Xr4ti Master Cylinder in Top Condition

    Roadtrips can only be enjoyable when you're confident with your vehicle's safety. One of the most significant components that determine car safety is its brake system, specifically the brake master cylinder. To ensure that your Merkur Xr4ti master cylinder is kept in good, working condition, here are some tips you can try:

    • Clean the master cylinder periodically.
    • Although the master cylinder is built tough, it may still get worn or damaged over time. That is why it's recommended that the master cylinder be cleaned regularly. One way to do this is to use a parts cleaner followed by a brake cleaner. Keeping the master cylinder clean gives the cylinder a longer service life.
    • Choose and use only the right cleaning materials.
    • There are a lot of chemicals used for cleaning available in auto parts stores. However, not all types of cleaning agents can be used to clean the brake master cylinder. One safe-to-use cleaning agent is the degreaser. It's effective for removing oil residue that has accumulated in the cylinder over time. Other essential cleaning materials include the wire brush and a brake cleaner. Because the master cylinder and the brake booster both have contact with the brake fluid, using a brake cleaner is highly recommended. Moreover, the wire brush is tough enough to be remove grime and grease built-up after a chemical agent has been applied onto the cylinder.
    • Regularly check the brake fluid levels.
    • It's ideal to check the brake master cylinder at least every couple of months. You need to take note of the fluid levels, especially if the cylinder was low in fluid upon your last check. Pop up your hood and inspect the master cylinder visually. If both the cylinder are filled with enough brake fluid, then there's no problem. Aside from the brake fluid, it's important that you check the cylinder's bottom for stain marks, wetness, or gunk. This could indicate that the master cylinder is leaking fluid.
    • Avoid leaving the brake fluid reservoir open.
    • When checking the brake master cylinder for fluid levels or for other maintenance tasks, make sure that you replace the reservoir cap as soon as possible. While the reservoir is open, oxygen or water vapor in the atmosphere may enter and contaminate the brake fluid.
