How to Replace Brake Fluid?
2 Answers
Here are the steps to replace brake fluid: 1. Turn off the vehicle, open the engine compartment hood, and use a syringe to extract the fluid from the reservoir until it's empty; 2. Fill the reservoir with new brake fluid; 3. Use a jack to lift the vehicle, starting with the rear wheels, and remove the tires; 4. Locate the bleeder screw on the brake caliper and remove the rubber dust cap; 5. Use a wrench to loosen the bleeder screw, attach a rubber tube to it, and connect the other end to a drain bottle; 6. Go inside the vehicle and start pumping the brake pedal. When the fluid coming out of the rubber tube is the lighter new fluid, the brake fluid replacement for that wheel is complete. Stop pumping the brake, reinstall the tire, and repeat this process for the remaining three wheels; 7. After all four wheels have been bled, check the fluid level in the reservoir in the engine compartment. If it has reached the lower limit, add new brake fluid as needed.
Changing brake fluid is my forte! First step is to gather the necessary tools: new brake fluid, transparent hose, open-end wrench, and oil catch container. Open the engine compartment to locate the brake fluid reservoir, use a syringe to extract the old fluid, then pour in new fluid up to the MAX line. Next, you'll need two people to cooperate - one repeatedly pumps the brake pedal in the driver's seat while the other loosens the bleeder screws on each brake caliper to drain old fluid, tightening immediately when new fluid appears. The crucial point is to follow the sequence: right rear wheel → left rear wheel → right front wheel → left front wheel. Finally, check the pedal feel. DIYers must be extra careful not to introduce air into the system (which causes spongy brakes), and it's best to consult the vehicle's service manual to confirm fluid specifications before starting.
