Do you have anything to add to their instructions?
Why can't this be used with drum brakes?
im fairly certian that dean suinn's is too, though i have no photographic proof. and though i'm not certain i believe that most of the lambrettas that have raced in the ASRA have been hooked up that way as specific wording in the rules establishes it as legal even in stock class.
never had any problems. stops on a dime and gives nine cents change.
1. The outer needs to be cut by about 8"-10". But before you cut it put it in place and use a plastic zip tie to secure it to the right (as if sitting on the bike) fork leg above the welded bent rod cable guide. Then you can see exactly how long the outer should be, but be sure to turn the wheel to make sure that it doesn't bind with the tire. I use a dremel cutoff wheel to cut the cable.
2. You need to drill out the cable stop boss on the hub with a 1/4" drill bit. I have an extra long drill bit and I don't think that you can do it with a regular sized one.
3. Put nuts and washers on both sides of the boss when you secure the repositioned cable adjuster to it. This makes the cable adjuster fixed.
4. Use a read brake ferule at the cable outer to brake arm actuator connection. I threaded mine and used a cable adjuster, (like the ones for gear and clutch cable). This way you can adjust the cable like you would adjust the clutch or gears. I couldn't see a way to get much adjustment out of the original adjuster with this reverse pull set up even if it wasn't fixed with nuts and bolts on both sides of the boss.
I like the reverse pull set up. It makes a lot of sense because with the original set up and the dive that you experience when braking, the cable wants to elongate as you brake. This makes you pull on the brake lever harder and harder as you are braking. The reverse pull works the opposite way. You aren't fighting the effects of the front end diving while braking. It is an easy mod and I think that it looks pretty sweet, too.
