I had a 2sets of LED series circuits which runs with 12V DC, 1A as shown below . Each set will be of 3 series of four LEDs. My problem is that when i connected to 12VDC,1A source, the set1 brightness is higher than set2. how to overcome this problem ?

Wire each set individually to the power supply.
There will be some voltage drop in the wiring, depending on both the current and on the length of the wire. In your circuit, set 2 will receive a lower voltage than set 1 due to the additional wire between the sets.
Increasing the wire gauge (diameter) will also reduce the voltage drop in the wiring.
