The new slx brakes from rose are set up eurpo style, how easy is it to change hoses? How do you bleed these - can't find anything on the shimano site ๐Ÿ™ do i need the funnel?

Very easy to change hoses over without bleeding. Bleeding is much easier with the funnel, I certainy wouldn't like to do it without.

Piece of piss Rob.

Take the wheel out, pump the lever until the pads meet, snip the hose, install new olive and insert and refit to lever then push pistons back in. Works pretty much every time and leaves no need to bleed.

If you don't manage to get it to work then pop by the shop and I'll show you how to bleed them.

I did my Deore 596 without even pumping the pads out. Took less than 20 minutes to fit the levers, callipers and cut both hoses. Not even enough time to drink a beer.

If you bought front and reat brakes just swap the hoses over without cutting them, other than that as above.

That is fine if you have a very large frame but if you have anything else it will leave big tree catcher loops of hose waggling about.

matt - sounds like when i did my old slx and xt ๐Ÿ™‚

is there a bleed nipple on the lever to open when i push the pistons back in case any air needs to escape?

Nope, just leave everything shut, it'll be fine

Here's a guide that I used:

And here's a great video on bleeding them:

If you use the former, you won't need the latter. Just keep the end of the hose above the caliper at all times,

The link is for bleeding 'old' style Shimano brakes. The new ones have a bleed port on top of the reservoir cover.

Anyone know if I can bleed new ones like the old ones by completely removing the reservoir cover?

easier and less panicky with 2 people, one to push the pistons back in whilst you re-insert hose with lever/resevoir need new olive & insert

Yes, but do I need that Shimano funnel for bleeding the new style or can I get away without it somehow?

Well I managed to completely f this up last night. One lever the olive crushed at a funny angle so it leaked from the lever, the other I can,t retract the pads now. Need to buy a olive and bleed kit now. With a thread of people saying how easy it is doesn,t help my mood!.
