Newer domestic cars and trucks brakes are not all that complicated, nothing much has changed, only the introduction of abs (anti locking braking system) Pretty sure your truck will have abs system, so it is extremely unwise to push the piston back into the cylinder as it may damage the abs controller pump (if you want to play Russian roulette) so open up the bleeder valve and depress the piston slowly and close it as soon as you stop pressing the piston. Make sure there is no air in the system after you do the brake job, heard horror stories of people working on their cars and forgetting to bleed the brakes properly and smash into the most convenient thing. But otherwise its not very difficult and can be done with basic tools.
