My personal experience: had the wheel bearings serviced at CW. They misrouted the break line as they finished. The wheel/tire rubbed brake line and all the fluid went away as I braked. NO more brakes. Had to order the special brake line so I rigged a bolt in a Tee fitting to seal the system. Worked good with three brakes until I was able to replace the damaged line. Still and all, I have had both, electrical-magnetic brakes and electrical over hydraulic disks. I will not go back to magnetic brakes. YMMV
