Q: My Toyota brake warning light is always on but the fluid level is fine — is it the connector?
A: A brake warning light that stays on with a full reservoir indicates an open circuit at the level sensor — most commonly caused by a corroded 2-pin connector. Inspect the connector before replacing the level sensor or reservoir cap assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
