What is the method for replacing automotive brake fluid?
2 Answers
Steps for replacing automotive brake fluid: 1. Park the vehicle on level ground, turn off the engine, open the hood, and drain the fluid from the reservoir. 2. Use a funnel to fill the reservoir with new brake fluid. 3. Use a jack to lift the vehicle and start by removing the rear tires. 4. Remove the rubber dust cap from the brake caliper. 5. Loosen the bleeder screw with a wrench and attach a rubber tube to it, connecting it to a drain bottle. 6. Inside the vehicle, press the brake pedal while observing the fluid drainage until the fluid level in the reservoir under the hood reaches the lower limit. 7. Start the vehicle and test the brakes in a relatively safe area.
I've done this myself, and it's quite particular. You need someone to help press the brake pedal. First, drain the old brake fluid from the reservoir. Then, fill the reservoir with new fluid. Next, locate the bleeder screws on the brake calipers of all four wheels, starting with the right rear wheel, which is farthest from the driver's seat. Have your friend slowly press the brake pedal while you watch the old fluid and air bubbles being expelled. Once the fluid runs clear without bubbles, tighten the screw. Remember to keep adding new fluid to the reservoir while bleeding the air—never let it run dry, or you'll have to start over. After finishing all wheels, pump the brake pedal firmly several times until it feels firm, indicating success. Finally, check the fluid level again after driving for a few days to be safe.
