Hi,
Hopefully I get my new frame tomorrow and I want to get it build up tomorrow night for a peaks days Saturday.
I have a new set of hope tech 3 E4’s ready to instal so just wondering if it’s possible to do so without needing a bleed afterwards.
Cheers

They will need a bleed.

Nope, I’ve shortened Hope brakes before, reused the olive and insert and not had to bleed. YMMV of course! But if you’re careful not to lose any fluid when you detach the hose from the lever you should be ok.

I would say have what you need to bleed them. I did some Deores a while back. Got away with it on one other needed a good bleed. No real reason hope would be different (ie it’s possible but not guaranteed).

Edit I am aware they are not hopes but mechanically it’s pretty much the same process.

Yes, it can be done if you’re careful and follow these steps (with brake left mounted on bike, so that lever is higher than caliper):

1) start by removing the pads and wheel and carefully pulling the brake lever so that the pistons move outwards, but not too much (leave at least 5mm between them)

2) unscrew the hose from the lever. The fluid shouldn’t leak out from either end.

3) cut hose to desired length, making sure you hold it upright so fluid can’t drip out. fit nut, olive and insert

4) screw hose back into brake lever

5) remove lever reservoir top cap (change angle of lever so that reservoir is horizontal to ground, as per bleeding)

6) carefully push the pistons back in all the way. when you refitted the hose to the lever, some air will have become trapped, and this will have resulted in a small air bubble sitting inside the hose. by pushing the pistons back in, this will push the air bubble up into the lever and you should see it appear in the fluid reservoir, and float to the top.

7) refit reservoir top cap. refit pads and wheels and pump lever to reset pistons. make sure the brakes are not spongy – hopefully you’ll know what they should feel like.

good luck 🙂

I would give them a bleed just to be sure. They have to be some of the easiest out there to bleed too
