ltwt1981 Posted January 19, 2006 Share Posted January 19, 2006 First many thanks to Tonk and Jon White for advice and their threads on this. Really just a brief description of how mine went. You will need a lathe, grinder, taps and dies, pillar drill (better still a mill) and some patience. I started with a stub axle and hub in the workshop together with disco/RR rear callipers and discs (not LR). You have to make the calliper bracket, I used 12mm steel but I think 10mm would be better, I just happened to have some 12mm. I formed the bracket shape using the hub to mark a circle and a drum brake back plate for the inner circle hole. This means it will fit on the stub axle correctly. I then looked at the caliper and drew up where I thought it should go. Made it all in card first including a mock disc of exact diameter. The disc I used has the centre machined out and the hub requires some machining as well to fit. Mine is like the TIC brakes, see their web site for pics. The disc is fitted to the back of the hub with five bolts tapped into the hub. I used the centre of abrake drum machined to fit into the rear recess of the disc to centre the holes exactly. This disc can be fitted on the front of the hub and one hole central between the studs drilled through both. Move it round one drill the next hole through the first in the disc and so on. With five holes drilled turn over and drill all five back through the hub and disc. You now have a template to drill the brake disc, place it in the rear recess and drill with a pillar drill all five holes. If you machined right in the first place you have them in the right place tap the hub, drill out the disc holes and bolt up with loktite or similar. Mock it up on the bench and offer up the caliper and mark the holes. I made the caliper bracket in aluminium first so I now have a template for this as well. After this its all bolt together and mod brake lines to suit. You need a 6mm spacer on the front of the hub for the wheel to clear the caloper, I machined out a brake drum centre as its complete with all the holes you need. With my 12mm calliper plate I found I needed lnger bolts to the axle and to mill sme recesses as the bolts fouled on the hub, I think 10mm may clear or at least not require th milling. I thought about countersunk bolts but I'm not sure, any comments. Or anyone got any in imperial to fit, needs 12. I cut the caliper bracket roughly with a jig saw first, ground and filed to shape. Stich drilled and filed the centre hole. All seems to work well other than comments on my other thread re pedal a bit firmer. Will post pics when I do some any questions please ask.
