The brake fluid reservoir level is low.
BYD ATTO 3: Low brake fluid; check for leaks and brake pad wear
Symptoms
- The brake fluid reservoir level is low. [1]
Possible causes
- The manual links a low fluid level to checks for braking system leaks and friction lining wear. [1]
Checks
- Check against MIN/MAX; have a qualified technician check for leaks and brake pad wear. Do not conclude that the master cylinder has failed from the fluid level alone. [1]
What to do
- Identify the cause before repairs; use brake fluid of the original specification. Do not mix fluids or mask the problem by repeatedly topping up. [1]
Applicability and limits
- Only applies to the corresponding ATTO 3 configuration in the New Zealand English-language owner's manual; the manual date is not treated as an applicable model year. No actual vehicle model has been linked. Do not extend to vehicles with the same model name, other powertrains or other markets. Scope: unknown [1]
- Only applies to the specific configuration in the cited manual; do not assume applicability to all vehicles with the same model name.
