Review on 🔧 GM Genuine Parts 25780186 Parking Brake Control Module: Reliable Assembly for Efficient Brake Control by Richard Gross

This was an exact replacement for my 99 Sierra. However, it is not easy to change. There is a video on YouTube about the Tahoe replacement that is exactly the same. Don't rush and don't get frustrated. Just in case, don't forget to take an intermediate brake line with you. This is Dorman C660214. Good luck and patience. Only remove the pin in the middle after you have installed it and, if necessary, also adjusted the brake lines under the axle!
