How to Replace Brake Fluid for Peugeot 307?
3 Answers
Peugeot 307 brake fluid replacement method is as follows: 1. First, replace the brake caliper. 2. Then loosen the bleeder valve, slowly press the brake pedal all the way down, and repeat the operation every 2-3 seconds until new brake fluid is expelled. 3. Finally, repeat the operation for each wheel to complete the brake fluid replacement. The reasons for replacing car brake fluid are as follows: 1. Moisture or impurities in the air can enter through the vent hole of the oil reservoir, which will lower the boiling point of the brake fluid. 2. During prolonged braking, the brake lines are prone to vapor lock, resulting in reduced braking force or brake failure.
Last time I changed the brake fluid for my Peugeot 307, I followed these steps. First, open the hood and locate the brake fluid reservoir, cleaning it thoroughly to prevent debris from falling in. Keep the reservoir cap clean after unscrewing it. Prepare a new bottle of DOT4 or DOT5.1 brake fluid, along with a clear hose and an empty bottle. It's best to have two people cooperate—one to press the brake pedal and the other to work under the car. Start with the wheel farthest from the reservoir, the right rear wheel, followed by the left rear, right front, and left front wheels. Loosen the bleeder screw with a wrench, attach the hose, and place it into the empty bottle. The person in the driver's seat should slowly press the brake pedal all the way down and hold it—this will allow the old fluid to flow out through the hose. Tighten the screw before releasing the brake. Repeat this several times until the new fluid runs clear. During the process, always monitor the fluid level in the reservoir to ensure it doesn't drop below the minimum line, and top it up with new fluid as needed. After changing all wheels, bleed the system by pressing the brake pedal a few times to check the braking force. Remember that old brake fluid is toxic and must be disposed of properly. The whole process can be done in about an hour, but safety is the top priority.
I just learned how to change brake fluid not long ago, and tried it in my own garage last time. You need to prepare new brake fluid, a hose, a wrench, and a collection bottle beforehand. The brake fluid reservoir of the Peugeot 307 is located on the left side of the engine, and the plastic tank is quite obvious. Changing the brake fluid requires two people to cooperate: a friend sits in the driver's seat and presses the brake pedal as I instruct, while I operate near the wheel. I removed the wheel to expose the caliper's bleeder valve, starting with the right rear wheel. After loosening the bleeder screw and connecting the hose, my friend pressed the brake pedal until the old fluid turned clear before stopping. The key is to coordinate the commands well—when the brake pedal is pressed, it must not be moved, otherwise air will enter. After changing the fluid in each wheel, new fluid must be added up to the MAX mark. After changing all four wheels, my arms were sore. Finally, during the test drive, I repeatedly checked the brake pedal feel to ensure everything was fine. After doing it once, I realized it's not that difficult—just a bit time-consuming.
