Traveling elderly scooter want safe, then we must pay attention to safety braking system, so check the focus is the amount of brake fluid, confirm whether the storage tank baseline. When the brake fluid significant reduction than the previous inspection, the possibility of failure is very high. Electric car brake line leak also need to pay close attention, hand row of cars fitted with a clutch, it also should be noted that the amount of fluid two four-wheel electric vehicles, if the fluid volume reduction and into the air, you can not brake. Therefore, maintenance of the brake system most in need of attention is the brake fluid, if the fluid levels are low, the air entering the brake will become insensitive. Also, check the electric automobile clutch, try to pedal, check intermittent points, bad or accurate point deviation is in need of repair. 1, the brake fluid storage tank is translucent resin, cans, if dirty, just wipe with a cloth-wheel electric vehicles older, you can make a simple visual inspection. 2, the amount of brake fluid and brake wear plate is closely related to slowly decrease when there is no problem, if the rapid decline, for the time being to make up after the observation. 3, through the card box display window to check the remaining amount of brake fluid, can also take note of the brake pipe scars. 4, the card box, disc brakes with roller spray cleaner to remove dust grease, so that the brake sensitivity. 5, the clutch, first check the amount of fluid storage tank engine room, can not be separated from the clutch insufficient. 6, fluid clutch and brake fluid using the same, there is a pot you can spare. If there is sufficient brake brake fluid, the braking force can be conductive, the amount of liquid to reduce the wear of the brake plate closely. The possibility of a little slowly wear normal four-wheel electric car future, if the rapid wear and tear, failure is very high. About the electric car brake failure, if that is wrong, you should immediately check to the repair shop. Maintenance is easy to forget the most important content - periodic replacement of brake fluid elderly scooter three regular maintenance in addition to changing the filter, oil change, check the various level, check the brake system and check the lights, etc., tend to forget an important maintenance --- periodic replacement of brake fluid content. According to automotive repair manual introduction, two or traveling more than 50,000 kilometers every brake fluid must be replaced.
