The steps for bleeding the brake fluid are as follows: 1. Press the brake pedal continuously 5 to 6 times; 2. Keep the brake pedal pressed, then immediately loosen the air screw on the right rear wheel brake caliper and quickly tighten it again; 3. Repeat this action until the brake fluid shoots out in a straight line from the air screw. Brake fluid is the liquid medium that transmits braking pressure in hydraulic braking systems, used in vehicles with hydraulic braking systems. Its characteristics are: 1. Low freezing point: It maintains good fluidity at low temperatures; 2. Extremely high boiling point: It does not create vapor lock at high temperatures; 3. Minimal quality changes: It does not corrode or soften metals and rubber.

I've bled the brake system several times, so here's my step-by-step process. First, find a level ground, use a jack to stabilize the car securely, and remove the wheel—safety first. Get a friend to help; this job requires teamwork: one person sits in the driver's seat to press the brake pedal, while the other handles the wrench and a clear bottle for bleeding. Start with the wheel farthest from the master cylinder, usually the right rear. Keep the brake fluid reservoir full to prevent air from sneaking in. Press the brake pedal slowly, open the bleeder screw on the wheel hub, and watch the fluid flow into the bottle carefully until no bubbles appear, then tighten the screw and release the pedal. Repeat a few times to ensure it's clean, then proceed in order: left rear, right front, and left front wheels. Finally, check the fluid level and test the brakes lightly on the road. Don’t rush the process—air in the system makes the brakes spongy and dangerous. This method works best after changing brake fluid—it saves money but requires patience.

I bled my brakes myself last year, and it was quite practical. The key is teamwork: one person pumps the brakes while the other operates the bleeder screw. All you need are a wrench and an empty bottle for the old fluid. First, jack up the car and remove the wheel for safety. Keep the master cylinder topped up with brake fluid to prevent dry pumping. Start with the wheel farthest from the master cylinder, like the right rear—pump the pedal, open the bleeder screw to release fluid, close it once bubbles stop, then release the pedal. Repeat for other wheels in the correct sequence. Top up fluid if it gets low mid-process. I recommend wearing gloves—fluid can splash. After finishing, test brake firmness by pressing hard before driving. If still spongy, air might remain. DIY saves money, but beginners should visit a pro—brakes are life-critical. Tool kits are available online, and the job usually takes just over ten minutes.

Briefly share the method of bleeding brakes: work in pairs. One person presses the brake pedal while the other uses a wrench to open the wheel screw, releasing fluid until no bubbles appear. Start from the farthest wheel, such as the rear wheel. Keep the fluid reservoir full. Repeat the sequence for each wheel. Don't forget to securely support the car and remove the wheel. Ensure the fluid flows cleanly during the operation. DIY can be convenient, but it's recommended to fully understand the process before attempting. The brake pedal should feel firm when done.

Exhaust brake air is critical for safety. I emphasize: a weak system intake brake is prone to accidents. Steps: lift the car and remove the wheels with two people cooperating. Prepare tools and a bottle for waste oil. Start with the farthest wheel, such as the right rear. Keep the master cylinder oil always full. Press the pedal, open the screw, let clean oil flow, then close the valve. Release the pedal. Repeat the process for each wheel in order. Proceed gently and slowly; top up with new oil if lacking. Improper operation risks drawing in more air. If inexperienced, seek professional repair—mistakes in brake repair have serious consequences. Wear protective gear throughout to prevent oil splashes. Before test driving, ensure there is no spongy feeling.

Remembering My First Brake Bleeding Experience: Called a friend to help. Jacked up the car and removed the wheels. I held the drain bottle and wrench, he pumped the brakes. Started with the right rear wheel, slowly releasing fluid until bubbles stopped. Tightened the screw and released the pedal. Moved to the left rear and repeated. Topped up with new fluid as needed. The whole process was gentle, requiring patience—no rushing. Finally tested for firm brake feel. Key was monitoring fluid level to avoid air ingress. DIY learning was fun and saved shop fees, though now I stick to regular to prevent issues.
