I have a 98 zj 5.9 and my brakes suck. I have put on stainless steel brake lines performance friction z rated pads and I still cant lock up my brakes. I have 265/70/16 tires on but it should still lock up the brakes. If it is wet out I can barley get the abs to activate. I have also changed the fluid and bled the brakes. Any suggestions would be great.
