Problem overview

Some Cadillac Seville owners report experiencing brake failure due to contact between the brake lines and the engine block, which can cause leaks in the hydraulic system. This contact may lead to abrasion and damage to the brake lines, resulting in brake fluid loss and a significant reduction or complete loss of pedal pressure. Additionally, some owners have noted that hydraulic system leaks can often go unnoticed until braking performance is severely compromised, making it difficult to stop the vehicle. It is essential for owners to address any brake fluid leaks immediately to prevent complete brake failure and ensure the safety of the vehicle and its occupants.
