I just got my kart seller was telling me re built the brakes also new rotors I have not gotten a chance to drive kart yet just in stand going this weekend. Reason I am asking the front brakes on my sons Praga are floating so they make contact but wheels spin free this is a older intrepid 2011 so not sure if they will break in and spin free once driven or if I need to do something before driving kart. thanks for any info!
