Class C just locked up front wheels

Ohh the old never ending Ford front brake seizure issue. Most of the time this is caused by the steel brake fluid pins rusting inside the line due to sitting too long. Rust falls into the caliper piston resulting in seizure. Stainless steel pins would eliminate the issue. I've had two fords with same exact issue: a 72 Galaxie and a 93 Class C. Regular fluid changes will remove the moisture causing the rust, but the rust inside the piston chambers will need to be cleaned by removing the pistons and cleaning by hand. The calipers and Pistons should be fine once the rust, old pins and old fluid are completely removed. Also have to be weary of cooking the grease inside the wheel bearings. They will become hot enough to boil water and cook off the grease if overheated too long.
