Problem overview

Some Cadillac Escalade EXT owners report experiencing brake line leak issues that can significantly impair stopping ability. These leaks may stem from various sources, including seal failures, problems with brake lines, or issues with the master cylinder reservoir. As brake fluid escapes, air can enter the braking system, leading to reduced stopping power and potentially resulting in a situation where the brakes fail to function properly. Owners have noted problems related to brake fluid leaks, hoses, lines, and fittings, emphasizing the urgency of addressing these concerns to ensure safe driving. In certain model years, manufacturers have issued recalls to rectify known brake fluid leak issues. Remedies may involve updating the electronic brake control module (EBCM) software, which can often be done at no cost to the owner. It is essential for owners to have their vehicles inspected and repaired by qualified technicians if a brake line leak is suspected to maintain safe braking performance.
