Brake line flush by dealer

Has anyone ever done this to their truck?? Sounds like a $130.00 flushed down the drain. Sounds like an expensive "bleeding of the brake lines". Is this worth the money?? Is this something I can do myself?? Never heard of this before. I have 1997 Tacoma 4x4. Thanks for looking.

 

get a full flush done elsewhere or do it urself........its good practice because brake fluid pulls moisture from the air.

 

Thanks Brother!!
