Brother FB100 Repair Kit with instructions - Most FB100 diskette drives fail because the drive belt gets gummed up or breaks. Making the FB100 repair is something that you can do yourself with the repair kit and instruction sheet if you have some mechanical ability and patience. The instruction sheet has step by step instructions to disassemble the FB100 diskette drive, replace the belt and reassemble the diskette drive. The repair kit has a new drive belt and the instruction sheet. The instructions are written for a Tandy disk drive which is the same disk drive that Brother used in the FB100. Something the kit can't help with is if the FB100 has an electronic problem. In other words, if the circuit boards are damaged or faulty either from age or electrical surge or any other related problems.
