I have a awful sound when I step on the break pedal, sounds like its hissing or something just had a break job on the truck and it didnt change anything.. Please help!!!!!

 

Does it happen at high speeds, low speeds, both? My guess would be that your pads are in need of replacement. A few more details will probably help you get more of a response.

 

It happens both high and low speeds. and it sounds like its coming from inside the truck were the brake pedal comes through, my little girl was with me last night and ask me what that frog sound was. sounds like a hydrolic noise, but I dont have any leaks.

 

Oh, OK. At first I thought it was an outside noise. My original advice is completely wrong then, so please ignore that. I'd get that looked at by a qualified mechanic ASAP. You don't want to be driving around with brakes that don't work. I really don't know what that would be. If you can't figure it out on your own, just take it to a good mechanic or the dealer.

Good luck!
