I did that first off, hoses, fluid and new pads. It was lot better fade wise due to the fluid, but then that showed up the heat-vibration on the OE discs, so they needed doing next...
The car wasn't modded power wise when the lines/fluid/pads went on, but they are such heavy cars the OE brakes will always struggle, as soon as the JB3 went on that really showed them up.
