BYD DOLPHIN: Brake fluid below MIN; check for leaks and pad wear

BYD DOLPHIN: Brake fluid below MIN; check for leaks and pad wear

Symptoms

• The brake fluid reservoir level is below MIN. ^[1]

Possible causes

• The official manual requires checking for brake system leaks and brake pad wear; the fluid level alone does not establish damage to a caliper or the master cylinder. ^[1]

Checks

• Check the fluid level according to the manual and have a qualified technician inspect for leaks and check the brake pads; if braking is abnormal, stop driving and contact a service provider. ^[1]

What to do

• Identify and address the cause of fluid leakage or wear; the fluid specification must match the original vehicle requirement, and different specifications must not be mixed. Do not substitute repeated topping up for inspection and repair. ^[1]
