If your car has a brake system, it’s important to power flush it every 6-12 months or as needed. Brake fluid can accumulate over time and cause your brakes to become less effective, so it’s important to flush out the system and make sure everything is working properly. Here’s how to do it in your Lincoln MKZ:
1. Park your car in a safe place so you don’t have to worry about it moving.
2. Open the hood of your car and locate the brake lines running from the front of the car to the rear.
3. Carefully disconnect the hoses from each wheel cylinder (see photo below) and discard them.
4. Next, remove the two bolts that hold the brake caliper on each side (see photo below).
5. Remove the caliper by pulling straight up on it until it comes free from the wheel hub (see photo below). Discard it.
6. Slide off the brake pad cover (see photo below), and then remove the four bolts that hold it on (two per side).
7. Replace these parts with new ones after flushing out your system: a new brake pad cover, two new bolts per side,
Background of the Power Flush Brake System
The power flush brake system is a feature that was first introduced on the Lincoln MKZ. The system is designed to help improve braking performance by flushing brake fluid through the system. Brake fluid can become contaminated over time, which can lead to decreased braking performance and increased wear on the brakes. By flushing the system, Lincoln believes that it can improve braking performance by removing these contaminants.
How the Power Flush Brake System Works
The power flush brake system works by connecting to the brake lines leading from the master cylinder. Once connected, the system can begin to flush the brake fluid through the lines. This process is repeated until all of the brake fluid has been flushed through the system. The master cylinder contains a sensor that monitors how much brake fluid is remaining in the system. Once all of the brake fluid has been flushed, the system will disconnect from the master cylinder.
Benefits of Using a Power Flush Brake System
There are several benefits to using a power flush brake system. First, by flushing the brake fluid through the system, Lincoln believes that it can remove any contaminants that may be present. This could lead to improved braking performance and reduced wear on the brakes
Procedure to Power Flush a Brake System
If you find that your brake system is not working as efficiently as it should, or if you just want to ensure that all of the brake system’s components are functioning at their best, it may be beneficial to power flush the system. This procedure can be done by following these steps:
1. Park the car in a safe location with the engine off.
2. Disconnect the negative battery cable.
3. Remove the front wheels.
4. Remove the rear wheel assemblies.
5. Loosen and remove the brake hose clamp on each side of the master cylinder reservoir.
6. Open the bleed screw on each side of the reservoir and allow fluid to flow into each line until there is no more fluid coming out (about 2 minutes).
7. Close bleed screws and reconnect all hoses, tightening hose clamps as needed.
8. Reconnect negative battery cable and restore wheel assemblies.
9. Start car and check for leaks.
What to do if the Brake System Doesn’t Respond When Squeezed
If your brake system doesn’t respond when you squeeze the pedal, there are a few things you can do to try and fix the problem. One possibility is that the brake fluid level is low. Make sure to add brake fluid whenever it drops below the “full” line on the dipstick. Another possibility is that one or more of the brake calipers may be leaky. If one or more of the calipers are leaking, they will need to be replaced in order to fix the problem.
Summary
There are a few things you can do in order to power flush your brake system on your Lincoln MKZ. The first step is to locate the bleed screw for the master cylinder. This is usually located near the rear of the vehicle on the driver’s side. Next, remove the screws that hold the reservoir cap in place. Once these have been removed, use a standard wrench to unscrew the bleed screw. Make sure to keep a close eye on the brake fluid level while doing this, as overfilling can lead to a mess later on. Finally, pour enough brake fluid into the reservoir until it reaches the top of the bleeder screw hole and screw it back in place. Be sure to replace all of the screws that were removed earlier in order to ensure a tight seal.
