Brake fluid is one of the most important parts of your car, and it’s important to make sure it’s always fresh and topped off. But is it really necessary to flush the brake fluid every time you change the oil?
What is brake fluid and why is it important?
Brake fluid is a type of fluid that is used to help stop a car or truck. Brake fluid is important because it helps to prevent the brake pedal from getting too hot and from sticking.
What are the symptoms of a brake fluid leak?
When you brake, the hydraulic fluid that is used to stop your car’s motion moves through the brake lines and calipers. This fluid is heated up by the friction of the pistons against the discs and can boil. If boiling occurs, it can cause metal particles to form in the fluid which can lead to a leak.
There are a few different symptoms of a brake fluid leak, but all of them indicate that there is something wrong with your brakes. One common sign is a decrease in braking performance. If you notice this happening, it’s likely that your brake pads are worn out and need to be replaced. Another sign is a strange noise when you brake; this could be indicative of metal on metal contact, which can lead to a brake fluid leak.
If you think that you might have a brake fluid leak, it’s important to take action and have your brakes inspected by a mechanic. If there is Definitely a leak, then the mechanic may be able to fix it without having to replace any parts. However, if there is any question as to whether or not there is a leak, then replacement of parts may be necessary.
How to flush your brake fluid
If you have an older car with drum brakes, it’s a good idea to flush your brake fluid every 5,000 miles or so. Brake fluid contains mineral oil, which can corrode your brake pads and discs if not flushed regularly.
To flush your brake fluid:
1. Park your car on a level surface.
2. Disconnect the negative battery cable.
3. Open the hood and remove the brake calipers by pushing down on the pistons and pulling them off of the hub. Discs should also be removed at this time if they’re in use.
4. Pour about 3 quarts of fluid into a container and add enough water to make a slurry.
5. Add the brake pads and discs, making sure they are submerged in the fluid mixture. Close the container lid and shake well to distribute the mixture evenly throughout the parts.
6. Reattach the calipers and hub, replacing any screws that were removed in step 3. Reconnect the battery cable and drive your car until it stops working (to ensure that all of the fluid has been absorbed).
When should you have your brake fluid flushed?
When your car has over 100,000 miles on it, you should have the brake fluid flushed. Brake fluid is a type of hydraulic fluid that helps the brakes work. Over time, brake fluid will break down and will not work as well.
Conclusion
There is no one-size-fits-all answer to this question, as the needs of every driver will be different. However, generally speaking, brake fluid should be flushed regularly if you experience any of the following symptoms: a grinding or squeaking noise when you apply your brakes; poor braking performance; or a strange smell coming from your car’s brakes.
