I am sure you could start with the forward most axle and work your way back to the rearward most axle and be just fine but I recommend starting with the rearward most axle and working your way forward to the master cylinder when bleeding brakes on either a trailer or vehicle. This method will ensure that all of the trapped air gets pushed out of the lines and does not work it's way further back. If you need a manual brake bleeder then you can use the Hand Vacuum Pump Brake Bleeder part # PTW87030.
