(c) If the department determines that a distributor, wholesaler, or retailer of replacement brake friction materials has been offering noncompliant brake friction materials for sale in the state, it shall allow the distributor, wholesaler, or retailer of replacement brake friction materials to establish that it obtained the noncompliant brake friction materials in good faith and after exercising due diligence in verifying that the material complied with this article prior to assessing fines and penalties pursuant to subdivision (a).

(d) In determining the amount of the civil fine to be assessed for a violation of this article, the department shall consider the particular circumstances of the violation, including, but not limited to, the amount of noncompliant brake friction material offered for sale in California and whether previous violations have occurred.

(e) The department may waive the imposition of a fine and issue a letter of warning if it determines, based on criteria, including, but not limited to, the amount of brake friction material offered for sale, the presence or absence of prior violations, and whether due diligence was exercised in determining that the brake friction materials offered for sale complied with this article, and that the violation of this article does not merit the imposition of a fine.

(f) A distributor, wholesaler, or retailer found by the department to have offered for sale noncompliant replacement brake materials shall cooperate with the department in the removal of the noncompliant brake friction materials from sale, inform the department of measures being implemented to avoid repeat violations, and provide the department with information that will assist in the identification and location of the source or sources of the noncompliant brake friction materials.
