Welcome to the forum, trials bikes do have forks, just no suspension forks, (unless you want to have them of course) We tend not to use suspension as it can make the front end feel abit too soft, wheras rigid forks maintain stiffness throught the bike (if you're doing anything on or around the front wheel, it makes it far easier). With your problem refferring to the brake, iwould reccomend moving the TPA (turbo pad adjuster) on the brake lever, to move the pads closer to the rim, or adjust where they are on the frame, muve them in towards the rim by loosening the mounts, moving the caliper then tightening them back up. if you are using standard magura pads, i would strongly recommend buying some new ones, zoo pads or green rock pads for smooth rims, heatsink reds or plazmatic crm's for a gring, search on here and you'll find many topics relating to pads. Nice to meet you, have a good stay. Matt
