I just recently got my Clark C-500-45 forklift running and have been working on other odds and ends. I went to move it and it doesn't want to move forward or reverse. I don't think the trans is slipping but almost like the brakes are holding it back. I did notice the e-brake cable was frozen and seemed to be holding up the lever on the small brake drum underneath so I removed the cable but it didn't seem to help. Are there common problems with the brakes that cause this issue? This forklift had been sitting for about 5 years. Thanks
