Anyone know anything about disc brakes?

  • Cup is not essential.

  • In fact I've never used one.

  • Yes, you can do it without the cup if you rather have a piece of cloth to catch the overflow.

    Or a sock like what +snottyotter uses to contain his other flows... ;)

  • Do you just take the cover right off?

  • Yellow cup is optional, you can dribble the fluid into the screwhole at the top of the reservoir, wiggling the lever every so often to encourage bubbles out.

  • Or just do it the right way and save time and reduce the risk of a messy clean up? :D

  • Yes for the older versions but just a single bolt for the new ones.

  • Assuming you have the yellow cup (wasn't included in the last few boxed brakesets I bought) and can find it.

    Cupless is only messy if you hurry and drop too much fluid so the rising bubble makes it overflow.

  • Can't recall now but the yellow cup I believe has to be purchase separately and doesnt come with brakesets.

    My preference is for a speedy bleed and to avoid the mess hence I will consider the cup essential.

  • It comes with their bleed kit.

  • You don't need to bleed it, it take five minutes to do.

    Put levers level, pull off hose carefully (after undoing the bolt), keep it upright, cut it to desirable length, make sure the bolt is at the bottom, put olive in, use yellow block and molle grip to hold hose, tap in the insert, once done, push it back into the levers, then tighten it up with the bolt.

    Once done, re-insert it back into levers.

  • ^Usually works and if not drop a couple of bits of fluid into the lever and squeeze a bunch of times with little top ups, throw the little yellow cup in the little yellow bin.

  • Indeed, even if you drip a bit, the reservoir take up a bit and still work great.

    Aboustely love Shimano, make fitting new brakes on customer's bicycle so much easier, and swapping them round from euro to english.

  • Do you not find the lever throw to be too much? When my pads are worn down the levers are getting damn close to the bars and it means I can't have my fingers under the levers like I would normally. Especially annoying with gloves on. Brakes are full, like, feckin' full of fluid too.

  • Air in there somewhere. Or they are just a bit shit.

    FWIW the pair of Magura MT6s I have - which seemed to suffer from excess leaver throw regardless of the bleed - almost thwarted the mighty Mario The Destroyer of Soho Bikes.

  • There is no air in there. There may be bear hair in there though.

  • I do actually also find the lever throw a bit too much, and although the performance of the brakes are very good - they still aren't quite as powerful as mtb ones (slx etc) on same size rotors.

    and yes my brakes are bled etc etc

  • Want.

    In hot pink, obviously.

  • does that mean you can now buy the massively reduced SRAM HydoR rim brake levers and use them with Hope disc calipers?

  • Hmmmm, not a bad point. The piston diameter on the hydro rim calipers must be a lot smaller than those in the disc calipers, but that could be reflected in the different in stroke length and the in-built leverage in the caliper arms. Hmmm...

  • Looks as though it'd still be a more expensive option than just buying some Shimano hydro shifters and calipers, and you'd still have the shit SRAM shifting. Out...

  • Other than pretty colours - what are Hope calipers like? Since I have such niggles with the Shimano ones maybe worth considering? Any lighter? Are the pads any better?
