Hi guys, so I bought an International Navistar 2001 school bus with hydraulic brakes. I am in OR the bus is in AZ, the owner is working with me on payments and giving me some time to pay it off and make arrangements to pick it up. what I am wondering is how I can ask him to check the hydraulic brakes to make sure they are good adequate and not leaking, without bringing it to a mechanic. Can you tell me the best ways to check on your own, I found some stuff on Youtube about pumping the brakes, I just wanted to see if there was anything else? Thanks
