This morning it was 8° when I started the truck. It's a 98 S10 Ext 4x4. I have lubricated everything that I can see moving on the parking brake pedal with WD-40. This morning I had to get out of the truck, pull the release handle with one hand and use a lot of force with my other hand to pull up the emergency brake pedal. The shop manual says to lubricate it with lubriplate(sp) grease. Anyone ever have this problem? It seems like the grease gets very stiff when cold and the pedal won't move under the spring power of the brake. It will not release even when the temp outside is 40°, but is fine after the cab gets warm. Looks like I may have to pull the brake pedal out, soak it in solvent and re-lube it.
