I am having an issue with the hydraulic breaks on a 2005

Customer Question

I am having an issue with the hydraulic breaks on a 2005 international 4300 box truck. The truck builds pressure for the breaks, but if you are sitting at a stop light and keep your foot on the pedal, it looses pressure slowly until it disappears
JA: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts. Is there anything else important you think the Heavy Equipment Mechanic should know?
Customer: so it builds pressure fine, but you lose it if you hold down consistently. You have good enough breaks to stop, but you can't sit at a red light without losing all your pressure
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Heavy Equipment Mechanic about your situation and then connect you two.
