So I have some Avid Elixir 1s which came with my 29er at the moment, which are a bit pants. The rear brake is acceptable -if I can lock the wheel easily why do I need a stronger brake right? The front brake is particularly bad though - likely needs bleeding... But instead of spending £25 on an avid bleeding kit, I thought I might be better putting the money towards some new brakes. I'm fairly set on some shimano brakes, given their rep for being reliable, and I had some Deore brakes on my old bike - for reference on a flat road I could pretty easily go over the bars if I grabbed a lot of front brake.
So with a budget of around £100, I can either afford to just replace the front brake with something like SLX or XT, and replace the back brake at a later date, or buy both a front and rear Deore brake.
So the question is, aside from the obvious weight difference, how much better are the XT(M785) (£85) brakes going to be than the Deore brakes? Also, if I go for just the front brake I could get the Deore brakes with a 203mm rotor - presumably that would get me more power too.
As you can see I'm pretty confused... Help me decide!
