Just put these on. A little tip, make sure you get the pin plunger into the little hole in the brass insert. I `thought` the pin was seated but it wasnt. That puts a little bit of pressure on the brakes, not much, but gradually enough to lock. Make sure you check the brake a `few`times. I could imagine being in a rush and the brake locking up down the road..... Got them off ebay, bout 35 pound. They look great and have a very good finish.
Ive had a few sets of these Chinese/Hong Kong brake levers on various different bikes & find them great value for money to be honest. Identical to the Pazzo levers i had on one of my Fireblades & a fraction of the cost. Build quality, finish & functionality was great. I tend to smear all bolts & pivots with a bit of copper grease before installation & make sure you make the necessary adjustments so that you have a little freeplay in the levers to eliminate any binding.
