Please also check out the statistics and reliability analysis of the 2000 Chevrolet Cavalier based on all problems reported for the 2000 Cavalier.
The 2000 Chevrolet Cavalier was purchased in July 2003 with approximately 32,000 mileage. On December 25, 2003 with 34,016 mileage the brake dash light came on, indicating a problem. The fluid was barely visible when checked. The mechanic later determined the proportioning value was losing a drop of brake fluid with the application of the brake pedal. The part was ordered and received from the local dealer. The repaired car was completed on January 2, 2004. He difference was remarkable. It wasn't until it was repaired that I realize how much it had lost it braking ability. Today I was told it was not a safety issue, since I didn't have it repaired by their authorized dealer only the dealer could make the determination of defective parts.
