How to Bleed Brakes?
2 Answers
The method for bleeding brakes is: 1. Locate the bleeder screw on the brake caliper and remove the dust cap from the bleeder valve; 2. Connect the bleeder port to a drain bottle using a rubber hose; 3. Depress the brake pedal and loosen the bleeder screw on the brake caliper, repeating this operation as needed. The brake is positioned below the driver's seat and the control console. Braking, also known as stopping, refers to the action of halting or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The working principle of brakes is: a wheel or disc is fixed on the high-speed shaft of the machine, and a corresponding brake shoe, band, or disc is installed on the machine base, which generates braking torque under external force.
When I tried bleeding the brakes myself, it felt easier than expected, just a simple DIY job. You'll need to prepare new brake fluid, a clear plastic tube, a small empty bottle, and a wrench. Park the car on level ground and engage the handbrake, then find a friend to help pump the pedal. Start with the wheel farthest from the master cylinder, usually the right rear wheel. Loosen the bleeder screw with the wrench, attach one end of the tube to the screw and the other end into the bottle, which should contain some old fluid to prevent air from being drawn back in. Have your friend pump the brake pedal continuously, and when it reaches the bottom, quickly tighten the screw. Repeat this several times until there are no air bubbles in the tube, then move to the next wheel in the sequence: right rear, left rear, right front, left front. Keep an eye on the brake fluid reservoir to ensure it doesn't get too low, and top it up with new fluid to prevent air from entering. The first time I did this, the tube wasn't secured properly, and brake fluid sprayed everywhere—luckily, it didn't damage the paint. After finishing, test drive the car; the pedal felt much firmer and safer. Performing this maintenance every two to three years can help avoid major repairs.
