Re: Front Brake Failure. Near Accident. Help?
Any change in levers can cause a hazard, not just "Chinese" levers. If the levers are well designed, and have the right bolt and bushing in place, they should not be sensitive to over tightening. But you can't take it for granted either.
The brake lever pivot bolt often has a shape that makes it stay the same effective length, no matter how much you tighten the bolt. You'd strip the bolt, wreck the nut, and still not bind the lever. If you have a situation where you can make the brake lever bind by tightening the bolt a certain amount, there is something wrong with the assembly. That might be the case if someone has put in a regular bolt in place of the proper one. Or it might be that the aftermarket lever is too thick for the application that they sold it for, and didn't fit properly in the slot. Or there used to be a washer directly over or under the brake lever, but that part was discarded.
You do have to check things over carefully when changing out parts to make sure that nothing funny is going on, especially with brakes.
