    One of the most over rated brakes out there. When WMB tested them on the dyno against old Deore, Deore offered more braking power, didn't overheat as quickly and weighed just 12g more.

    However they may need bleeding, new pads and certainly sounds like the caliper needs centralising.

    adjusted the lever reach?

    let them bed in?

    reset the pistons?

    cleaned the pistons on such an old brake?

    can i bleed these without a hope bleed kit?i used to be car mechanic we would un do the resvoir un do the bleed nipple and as long as resvior was kept constantly topped up no air would get in the system would this work on hope minis?

    The Mono Minis were lightweight brakes for lightweight use. They don't have much stopping power, but they do have lots of 'feel'. Some like this and some don't.

    Bleeding is easy: put a ring spanner over the bleed nipple and push a length of plastic tube onto the nipple long enough to reach a container standing on the floor. Turn the handle round on the handlebars so that the reservoir top is level. Take the top off the reservoir. Fill it with fresh brake fluid. Turn the spanner on the bleed nipple to open it and squeeze the lever. Close the nipple. Refill the reservoir, open the nipple, squeeze the lever, close the nipple. Repeat this until no air bubbles come out of the nipple or all the fluid has been replaced.

    Take care not to spill any brake fluid as it is not very nice stuff.

    yeah that was another way we did it when i was car mechanic,prop is that method needs two people. it also uses same brake fluid dot 5.1 as my feista , which is a tip for anyone actually cos the car stuff is alot cheaper!!so basically i dont need the flash 30 quid hope brake kit.

    Nope, i've not needed it on my Mini X2 Pro's or my Tech M4's and both have been bled. I use Tank-Slappers method.

    As for the power, if anything I find with my X2 Pro's that they teach your to be smoother and look ahead more, and they do allow you to be more controlled. This makes them an ideal race brake where you dont really stop as such. However, in an emergency I feel like they still have enough power. Now whether this is because the X2 version does have the claimed increase in power, or because your's need a bit of TLC and setting up i'm not sure.

    I have been wondering......when bleeding, how many lever pumps does it take on average until all the initial fluid should have passed through the system? My brakes are doing the same and im sure they need bleeding, although I didnt do the old diaphram trick so im sure thats not helping either.

    as many as needed until all the air has been removed.

    if there is air still in there then they are not bled.

    well how do you know when enough is enough! also, can you re-use the brake fluid?
  • nicklousenicklouse Posts: 50,675 Lives Here
    enough is when no more air comes out.

    No.

    Just like Tank Slapper said, you can do it without a hope bleed kit (I have one and have never used it) 8mm closed spanner, hose from bleed nipple to container and Dot 5.1 brake fluid.

    I've used Hope Mini's for years and have always found that after a good bleed, a good wash and sintered pads they have enough stopping power for me :)

    But then again I'm not doing the Alps or anything crazy :D
