How to Replace Brake Fluid for Peugeot 307?

Peugeot 307 The method for replacing brake fluid in a Peugeot 307 is as follows: 1. First, perform the brake caliper replacement. 2. Then, loosen the bleeder valve and slowly press the brake pedal all the way down, repeating 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 fluid reservoir, lowering the boiling point of the brake fluid. 2. During prolonged braking, the brake lines are prone to vapor lock, leading to reduced braking force or brake failure.
Replacing the brake fluid for a Peugeot 307 isn't overly complicated, but it's best done with two people. First, buy a new bottle of brake fluid—check the manual for the recommended type, usually DOT4. Gather your tools: a transparent oil container, a hose, a wrench, and an assistant. Start by cleaning any dirt around the brake fluid reservoir to prevent contaminants from entering the system. Then, have the car owner sit in the driver's seat while you handle the fluid drainage, starting with the right rear wheel (farthest from the driver). Loosen the bleed screw, attach the hose to the oil container, and let the old fluid drain in an orderly manner. Have the owner gently press the brake pedal a few times until old fluid flows out, continuing until the pedal feels soft, then tighten the screw. Repeat the process in order for the left rear, right front, and left front wheels, topping up the brake fluid reservoir each time to ensure the level doesn't drop below the minimum mark. After all wheels are done, add new fluid to the proper level and pump the brake pedal several times to remove air bubbles—only when the pedal feels firm is the job complete. Doing it yourself can save you around a hundred bucks, but if done incorrectly, trapped air could cause brake failure, so beginners should consider visiting a repair shop for safety.
Brake fluid absorbs moisture and deteriorates over time, leading to a lower boiling point which can cause brake failure during emergency stops, posing a significant safety risk. Before changing the fluid, ensure the vehicle is turned off and parked securely with the handbrake engaged. Prepare new fluid, tools, and an assistant. The process involves one person pressing the brake pedal while the other bleeds the fluid. Start with the rear wheels, connecting a hose to the bleed valve at each wheel to drain the old fluid. Continue pressing and bleeding until clear new fluid flows out. Be careful not to let the fluid reservoir run dry, and top it up with new fluid as needed. After completion, thoroughly check for leaks and test the brakes at low speeds on the road. Tools like fluid reservoirs are available at hardware stores and are quite affordable. I recommend changing the brake fluid every 20,000 kilometers or every two years to maintain optimal braking performance and ensure peace of mind while driving. The Peugeot 307 is a standard model, and doing it yourself isn’t difficult, but if you’re unfamiliar, it’s best to hire a professional for a small labor fee to avoid hassle.
