Great set but could be better. Includes instructions in multiple languages including English. You guys have to read. Works great except for leaking metal fittings. I tried dressing them with a blow dryer to warm them up which helped a lot. (I work with hydraulics all the time, so I'm an expert on these things.) When degassing the fluid while pumping, I noticed that it was sucking air out of the burr area of the hose. The fittings just won't seal the lines until I get into my tricks. So I took the mechanic's wire and pliers and moderately clamped the hardware. I can no longer separate hoses from fittings. I knew this was going to be a problem when I bled the brakes on my son's GT Karakoram. A few days later it's 3:30 am and I'm struggling with insomnia so I got my tools out and started investigating the problem and finding the above and the solution. FYI, a good strong zipper fits snugly in the pipe above the fittings. that will probably work too. This is probably much easier for most people who do not have an exceptionally well-equipped workshop. The GT had some issues with the rear brake bleed (it uses ProMax Decipher brakes), but the problem appears to be a leak. Arm cylinder inlet seal. This is not the fault of this kit, it is a malfunction of the brakes themselves. So we are upgrading the bike to Shimano hydraulics and I expect this kit will give me many years to come on his bike as well as on my KHS XC204 and Fuji Nevada 5 will serve. I'm not sure if this kit will work with the Magura HS33. Rim brakes (yes, hydraulic rim brakes) that I have fitted to my Caloi Andes Pro Hardtail or Caloi Supra Rigid Bike - I expect they will, will try to remember to update this after installation - I'm waiting currently on assembly to complete the installation.
