Grandson's bike has a rather fierce front brake which tends to throw
him over the handlebars when he uses it. How can I tame it?

Somewhere at the back of my mind, I seem to recall that you used to be
able to get brake blocks in different hardnesses of rubber. [So far, no
one has mentioned this, so I could be imagining things.] However, if I'm
right, the harder rubber will give less effective (softer) braking, and
vice versa.
