How to correct maintenance department 70cc motorcycle disc brakes proper brake system maintenance

Disc brake effect is good, but the structure is more complex, the use of maintenance is more important, the following describes the knowledge and maintenance aspects of system maintenance.

First, check before riding

1, the operation of the brake handle, braking force as "sponge", as Ruanmian, would not achieve the braking action, indicating that within the brake system into the air, go to the repair shop exhaust.
2. Check the brake fluid leaks, if the leak, please wipe leaking brake fluid, timely repair shop to find out the cause and repair.
3, check whether the brake calipers at the sediment, if there should be cleaned to prevent sediment causing friction disc brake cylinders and not return, affect the braking effect and brake system life.

Second, on a regular basis to check the repair station

1, with the main support teams from the  900cc two wheel racing motorcycle , put the handlebars straight. Check the brake fluid level is below the minimum engraved lines. When the brake fluid level is below the minimum line, to add the right amount of the same specifications brake fluid supreme engraved lines. Brake fluid level drops explanation friction plate, brake disc wear or brake fluid leaks, needs further examination friction plate, brake disc wear condition or leaks.
2, observe the color of the brake fluid, such as a change, indicating the need to replace the brake fluid has been aging.

3. Check the friction plate and brake disc wear. As shown on the right
Check the friction plate and the brake disc. When the friction pads wear to the line and must be replaced in pairs friction plate; brake disc thickness wear limit, different models are slightly different, Haojue Suzuki motorcycle brake disc wear limit is generally thickness of 3mm or 3.5mm, GW250 motorcycle front brake disc is 4.5mm, rear brake disc is 4.0mm.
4, if the brake handle Ruanmian, please follow the following method exhaust brake system:

⑴, the brake fluid in the master cylinder plus supreme engraved line position, close the lid, to prevent stolen goods enter.
⑵, with a hose, one end of the oil drain screw with the brake caliper is connected to the other end connected to the container.
⑶, fast clenched - release the brake lever a few times, then do not release the brake handle grip.
⑷, loose screws 1/4 turn open air, so that the brake fluid flows into the foam container, tighten the bleed screw.
⑸, release - Hold the brake handle, loosen the screws again open air bleed. So repeatedly, until no foam brake fluid flows into the container until and brake lever or pedal is no longer as "sponge" like soft.
⑹, tighten the bleed screw, disconnect the drain tube. Adding to the master cylinder brake fluid inside the supremacy engraved lines.
Note: If the brake fluid spills, immediately wipe clean the exhaust. Brake fluid may corrode painted surfaces, plastic and rubber parts. In the exhaust process, we should feel free to add to the brake fluid in the master cylinder, always make sure that you can see in the viewing window brake fluid.
