Brake boosters

[Slimtim]

I have just bought one through this forum - many thanks to the seller for a good description and despatch.

My question is, having never used one before, how will it actually work to improve the braking performance?

I am assuming that they are designed to prevent the forks or seat stays from flexing when operating the V brakes.

However, the mounting holes are elongated which means that it is possible for the brake bosses to move laterally when the brakes are operated - seemingly this defeats the purpose of the booster?

Am I missing the point?

When the bolts are tightened up it won't move, not in my experience and I've never heard of any other moving either.

Have a look at your stays before fitting with the brakes full on and after when fitted. You should notice that there's little to no flex.

Hi,

Result is better defined braking point and additional power.
