Any competent big truck shop should be able to send your brake shoes out for relining. Trying to fix brake fluid or grease-soaked linings is a total waste of time and effort, no matter what Mr. Bad Wrench on some website claims. Betting one's life on Mickey Mouse brake work puts everyone in danger- - -yourself and everyone who has the misfortune of sharing the road with you. Try NAPA for hydraulic repair parts such as wheel cylinders and a rebuilt hydrovac, and restore the brakes to perfect original equipment shape, unless you have a degree in automotive engineering and the research and development facilitles to totally redesign the brakes. The guys who designed that system weren't dummies who just fell off a turnip truck! Do you intend to do real truck stuff when you're done, or just cruise around to tailgate parties and car shows with an iced-down Yeti cooler full of Bud Light as the only cargo?
