Shimano Lever + Hope Calliper - 6 Months on

I wanted to give this brake mod a try because I found that Hope Trial Zone brakes have too much bite on the front, even with 180mm rotors and the standard red pads. The idea first came when I looked at the brake spares on TartyBikes and found that the Echo Tr and Trial Zone pistons were compatible; so, I thought that the seals would surely be the same size, which they are, give or take a tiny amount. The next stage was getting a mineral oil lever, and I wanted a Shimano one because their Servowave system in my mind would give more modulation compared to a linear leverage ratio lever. @onzatpro09 very kindly lent me a Saint m820 lever to test this mod. After 6 months my observations have been: 

  • The power on full squeeze is as good as the Trials Zones and MT7s that I have used but this has more modulation than either of those brakes in my opinion.
  • The lever throw is short and can be made incredibly short if the lever is overfilled.
  • I have not noticed any degradation in brake performance, which was common with the Trial Zones and required constant maintenance to work at their peak. I have not had to touch this brake for the 6 months that I have tested it.
  • I haven’t had to bleed it and it hasn’t leaked.
  • The visible confusion when explaining using a Shimano lever with a Hope calliper is always a bonus.

Should anyone wish to do this mod themselves, these are the steps that I took, and it is as easy as changing a pair of worn or perished calliper seals.

How things started

The first step was to completely dissemble the calliper and clean any DOT fluid that was inside. I used Loctite SF 7063, and this stuff is amazing at cleaning any contaminants. I also used this to flush out any DOT that was in the brake hose.

Next, was to pop the Echo seals in. I gave the pistons and where they sit a good coat of Hunters silicon grease. After that, it was just a case of popping the pistons back in and this is where I noticed that the Echo seals have a slightly smaller internal diameter than the Hope seals, but I have not noticed the lever feeling hard to pull.

One finished calliper.

Then it was time to assemble everything into a working brake using the Shimano barb and olive. I didn’t have a bleed funnel for Shimano brakes, so a zip tie had to do. Thanks to Ali C for this hack.
