Just finished installing TSM's rear disc brake conversion on my 14bolt FF axle. Quality product and easy to install although their instructions are a little vague. Took about 4-5 hours to complete and about an hour to finally get all the air out of the system. Was able to use both e-brake cables and must say, the K5 can really stop now. Great brakes and I can come off those hills now with plenty of reserve braking. Build it Bulletproof and take it fishing!
