Customer Question

yesterday we changed a hydro boost brake booster. we asked you where the ball bearing went and you said the back hole towards the firewall. we did what you explained but after bleeding the brake system and cranking the truck, the brake pedal was so hard we couldnt push it down, and the electric motor wasnt making a noise like usual, and then hydraulic fluid started dripping on the inside floorboard of the truck..... what could be wrong with the truck???
