Reach Adjust on Shimano hydraulic brake levers for MTB flat bar I am thinking to install Shimano BL-MT200 (or the BL-M315 depending on availability) on my son's bike (my son is 7 years old).  The bike currently has short reach brake levers for the current mechanical brake set.
I want to make sure the lever reach is going to be OK.  Shimano lists these brake levers as having &quot;Reach Adjust&quot;, however neither the manual nor the dealer manual have any mention on how this is done.  (which is unexpected because the Shimano dealer manuals are usually quite good)
How is the reach adjusted on these levers and is it likely the reach can be adjusted sufficiently for a child's hand?
Reach adjust is though a small (2.5mm?) hex key on the 'inside' of the lever. The MT400's definitely have it.
The amount of reach adjustment is quite wide, On my MT400's, from memory you can adjust it down until the lever very nearly hits the bars before the brakes are fully applied, so will be as good as can be for a child. Higher end brakes have better performance and adjustments like free stroke, that might help those small hands, but the price/performance/reliability of the MT400's or 315's is impossible to beat.
