Brake fluid is an essential part of any car’s brake system. But what happens when it starts to age?
What is brake fluid and why do we need to flush it?
Brake fluid is the fluid that helps to stop your car. When brake pads wear down, the brake fluid can become contaminated with dust and debris. This can cause the brakes to work less effectively and lead to a dangerous stopping distance.
To keep your braking system in good condition, it’s important to flush and refill your brake fluid every 3-6 months or as needed. Here’s how you do it:
1) Park your car on a level surface.
2) Fully apply the brakes by pushing down on the pedal until you feel a strong resistance.
3) Release the brakes and let them cool for about 30 seconds.
4) Remove the master cylinder cover by unscrewing it from the front of the car (see photo below).
5) Remove the brake lines by pulling them out of their holders (see photo below).
6) Remove the brake reservoir cap by turning it counterclockwise. The brake fluid level should be visible inside the reservoir. If it’s not, use a syringe or funnel to fill it up to the level shown in the photo below. Make sure to replace the cap once you’re done Flushing!\
How to flush brake fluid with an abs and hydroboost system
There are a few different ways to flush brake fluid with an abs and hydroboost system. The most common way is to use a standard 3/8 inch male ABS drain plug and attach a hose to the abs module. Turn on the abs and allow the brake fluid to flow into the drain until it reaches the reserve tank. Once the reserve tank is full, turn off the abs and disconnect the hose. Pour the brake fluid into a container and discard it.
Another method is to use a standard 3/8 inch female ABS drain plug and attach a hose to the hydroboost module. Turn on the hydroboost and allow the brake fluid to flow into the drain until it reaches the reserve tank. Once the reserve tank is full, turn off the hydroboost and disconnect the hose. Pour the brake fluid into a container and discard it.
What to do if you don’t have an abs or hydroboost system
If you don’t have an abs or hydroboost system, you can flush your brake fluid with a standard fluid drain and fill method. To flush the brake fluid:
1) Shut off the engine.
2) Remove the front wheel and axle.
3) Remove the brake caliper by unscrewing it from the rotor.
4) Remove the rear wheel and axle.
5) Disconnect the ABS line from the ABS reservoir.
6) Remove the cap from the brake fluid reservoir.
7) Fill a container about one-third full of fresh brake fluid and place it over the ABS line hole on the reservoir.
8) Insert a plunger or stick into the brake fluid and push and pull until all of the fluid is drained into the container. Replace all of the parts according to instructions in Step 5.
How often should you flush brake fluid?
There is no one definitive answer to this question as it depends on a variety of factors, including the make and model of your vehicle, the condition of your brakes, and how often you drive your vehicle. However, generally speaking, you should flush your brake fluid every 3 to 6 months or when the fluid looks dirty or icky.
Conclusion
Brake fluid is an essential part of any car, and it’s important to flush the system regularly to ensure that your brakes are working properly. Unfortunately, many drivers overlook this step and end up bleeding their brakes dry. If you have a hydroboost or ABS system, flushing the brake fluid can help prevent this from happening.
