Problems!

Now i have cosworth 4x4 front calibers, 2wd cossie discs and ferodo premier pads installed.
Problem is that right front brake has too much power compared to left and locks first. Other problem is that rear brakes are still too powerful. I visited in the MOT station they checked brake powers in rollers and told me that rear brakes are superb but front brakes powerless.. I today bought new front brake flexi pipes but that wasnt any help.
