MTB Brakes Mechanical Vs Hydraulic

For the past few years, I have struggled with the pro's / con's of using Mechanical Disc brakes versus Hydraulic Disc brakes.

I have always leaned towards the mechanical set-up and the more research uncovered that it was a better choice for me.  As with many things, it is a personal preference and arguments can be made either way as to what makes the most sense.

Below are some of the pro's/con's to the mechanical setup:

  • Mechanical Bennies:
    • Weight - lighter than Hydro's
    • Easy installation and adjustment
    • Easy Maintenance
    • Easier to fix on the trail if something goes wrong
    • No issues with pads touching and locking
    • Less $
    • Easy pad adjustment and modulation
    • no 'air bubbles' in lines, etc
  • Mechanical Con's:
    • less 'linear' progression vs Hydros
    • less finger power needed
Hydro Brakes:
  • Hydro Bennies
    • Less pressure needed to engage brakes (less white knuckling action)
    • More of a linear progression on brake engagement
    • Better 'stopping power'
  • Hydro Con's
    • Heavier
    • More $
    • Higher maint - bleeding of cables
    • More 'finicky' - brakes pads touching creates all sorts of problems (inadvertently grabbing the brake levers without the disc will cause some pain)!
    • Difficult trailside maintenance if something breaks
    • Less straight-forward pad adjustment (if needed)
I have ridden the mechanicals for about 10 yrs now and have seen the wife tinker with hydraulic setups for a while.  Having seen the higher maintenance required for hydro's has made my mind up for my preference.  I give up a little on the stopping power (still have plenty for being able to stop very quickly). That could be easily offset by moving to a bigger rotor (185) size as I am currently running the 160 (especially with 29'r wheel setups).

All in all, I have been super psyched with the Avid BB7 mechanical setup.  Big Thumbs up!
