hi i would like to know if anyone has changed the abs on dodge caravan to non abs brake? what parts would i need to get? do i need to change the hole brake system or just the booster and master cylinder? i believe the pump is out,[ brake pedal hard and hard to stop,but at times will be fine] but with all my research i have learned this is a ongoing problem so b4 i spend 300 to replace pump,i would like to replace with standard brake system if i can. thanks
