MG HS: Red brake malfunction warning light on; check the brake fluid
Symptoms
- The red brake malfunction warning light is on. [1]
Possible causes
- The manual requires stopping safely, checking the brake fluid and contacting a repair provider immediately; the light alone cannot confirm damage to the master cylinder or a caliper. [1]
Checks
- Stop safely, switch off the engine, check the fluid level as instructed in the manual and have the system inspected and repaired. [1]
What to do
- Have a qualified technician identify the cause; the warning must still not be ignored if the fluid level is normal. [1]
Applicability and limits
- Only applies to the English manual from the official European website and to the corresponding HS configuration among the combustion-engine configurations described; the manual date is not treated as an applicable model year. No actual vehicle model has been linked. Do not extend to models with the same 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
