Jiaozuo brake

What is a disc hydraulic brake? The disc hydraulic brake is controlled by hydraulic pressure, and its main components include brake discs, wheel cylinders, brake calipers, oil pipes, etc. The disc brake is characterized by simple structure, convenient adjustment, good high temperature resistance, fast heat dissipation, light weight but stable braking effect. After the cylinder oil pipe joint of the disc hydraulic brake is removed, air will enter the oil pipe and wheel cylinder. After reinstallation, there will be air in the braking system, causing the braking effect to fail. Therefore, after the joint is removed, the air must be discharged before it can be used normally. So how to bleed the disc hydraulic brake? What are the methods? The editor is here to answer everyone's questions one by one:

The method for bleeding the disc hydraulic brake is:

1. Add sufficient hydraulic oil to the main cylinder, grip the brake grip tightly, allow the air to exhaust, and then immediately connect the connector to the wheel cylinder.

2. Firmly grip the handle of the disc electric hydraulic brake to generate oil pressure in the master cylinder, then loosen the bleed screw to release the air.

3. When no more bubbles are generated at the bleed screw, immediately tighten the bleed screw, loosen the brake grip, and allow the master cylinder to return oil.

4. Repeat the second and third steps multiple times until the air is completely discharged. The action during bleeding must be coordinated to avoid operational errors that may cause air to enter the hydraulic system, causing the work to start over. It is also important to note that during the bleeding process, the hydraulic oil should be adjusted to the master cylinder at any time. The brake caliper is fixed together with the front fork guide column and is a fixed part of the braking device. The hydraulic brake disc is fixed to the wheel and rotates with the wheel. When holding the handlebar tightly, push the piston to move. Because of the non Compressibility of the brake fluid, the piston pushes the oil in the master cylinder to flow into the cylinder of the slave cylinder along the hose, and pushes the piston and friction plate to clamp the brake disc from both sides, producing great friction resistance, forcing the wheels to stop rotating, so as to achieve the purpose of deceleration or parking. Release the brake handle, and the return spring inside the master cylinder pushes the plunger back to its original position. The pressure in the oil circuit rapidly decreases, and the oil cylinder drives the friction plate to return to its original position, thereby releasing the brake.
