Trimmed my brake hoses. It was pretty easy.
-Remove grips.
-Unhook lever and mark hose length you want.
-Clamp lever on end of handlebars straight upwards, so the hose is in the air.
-Pull off rubber cover at the hose/lever connection and slide it down to the cable stop.
-Unscrew 8mm compression nut, and move it down the hose to the cable stop.
-Pull the hose straight out of the lever body. Takes some effort.
-Over a paper towel or something, cut the hose to the desired length. I used a razor knife. Make sure its a clean square cut.
-Turn hose straight up so not much fluid leaks out, and clamp it in the yellow holders that come with the brake kit. I clamped it in lock jaw pliers.
-Place new brass olive on the hose end. Olive should be up against the yellow blocks, and about 4mm from edge of hydraulic hose you just cut.
-Install new barb. Fit it by hand, then tap it in with a hammer or something. Should be flush.
-Unhook yellow plastic hose holders. Take end of hose and plunge it into the lever body. Screw in the compression nut. Don't go he-man tight on it, its not needed.
-Reinstall rubber cover, place brake lever where you want it, reinstall grips.
The whole process took maybe 10 minutes per side. Brakes feel great, no need to bleed them. Also, WAY more stopping power than my stupid Avid Juicys. Can lock up either wheel if I want it. Excellent modulation. Totally happy with the purchase.
