This report to to document a safety concern about the performance of the brakes in the 1999 miata. Although the miata has excellent braking in dry conditions, it has been noted that when driving in moderate rain in freeway traffic the brakes are ineffective for 2 to 3 seconds until they begin to dry out and function. This occurs with out the presence of standing water, just normal spray from traffic. This condition was also documented in the miata.net web site and it was reported that Mazda has been aware of this condition in europe and has issued replacement front disc sheilds as identified here: Right side P/N nc8533260A left side P/N nc8533270A nut P/N D06Y33042. Local Mazda dealership claim to have no notice of this issue or replacement parts. This condition is being experienced by more 1999 owners as documented on the miata.net forum under the topic "brakes in the wet" where this problem was first identified.
