Anyone know anything about disc brakes?

Should my RS785 calipers be biting more of the disc than in the image?

@branwen
A while back you mentioned switching around your RS785 disc adapters to better align the calipers. Was your issue similar?

On EV-BR-M985, the banjo end of the hose isn't specified. I bought a BH90 with banjo already attached, but chose the "for Saint" listing as it was cheaper and I didn't need a new banjo bolt.

Do BR-M820 and BR-M985 use the same size banjo fitting?

It'll be fine.

That sit way too high, is that a Shimano mount?

And ditch that quick release for a proper closed cam one.

Have you tried fitting the caliper without the adapter? Most PostMount forks ate natively 160mm.

Thought so!
They're not Shimano adapters, couldn't even get a matching pair - 1x Tektro + 1x ?. A Shimano 140 to 160mm was impossible to come by at the time. Will take another look but quick Google wasn't too promising though.

QRs were thieved from the MTB as a quick fix. Ashamed how long I've spent procrastinating between Shimano Ultegra/DA or DT Swiss RWS!

@Emyr I'm pretty sure they're natively 140mm on the CAAD10 Disc.

Thanks for taking a look. Going to resolve this and the new creaking sound... QR interface, chainring bolts, cassette, seatpost clamp/cradle... BB

Go for RWS, it was such an improvement on my TCX.

The hose fitting will be the same, but the bolt may be a different length. You can re-use the old bolt if it's not damaged though.

I got two BR-M985 calipers off ebay for about £15 each, one was missing the pad retaining pin and the other was missing the banjo bolt and the pad retaining pin's R-clip.

The Saint banjo bolt is a stubby M6ish, about 12mm long and fits parallel to the caliper mounting bolt. The M985 banjo bolt is the longest banjo bolt I've ever seen and runs parallel to the axle.

Don't have a 7mm spanner, but managed to get a decent amount of fluid syringed in and didn't lose much before closing it up again. Finished it of dripping into the lever reservoir, then spent 15 mins trying to dry the mineral oil off the caliper, lever and my hands. I should get some gloves.

Fitted some part-worn finned resin pads that were on my fatbike (gave that a brake and drivetrain refurb before a week in the Pyrenees). Should have a few hours to test it and bed in a new rotor before first game in this weekend's polo tourney in Lyon.

There are 2 kinds of 140->160 (/160->180) or +20mm post-post adapters:

and

Did you find your adapter in the parts pile, because it could be a 185mm (avid) one (that would explain it)

Yeah exactly the same issue on the same bike. Didn't have a problem with the Spyres that were on there before. Think I have the problem F&R. Got it better but still not perfect

I am planning to get this set: https://www.bike24.com/1.php?content=8;product=132835;menu=1000,2,15,117;pgc%5B15600%5D=15603;orderby=2

What olive/pin do I need? BH-90 or BH-59?

They look like the same ones I've got on my Orlo, which would be BH-59. But it should come with the correct spares if its a complete kit. There is also some reasoning that the difference between them is so minimal that it doesnt matter which one you use. I had two side by side and aside from one being a little longer, theyre pretty much the same

Ah thanks!

I think the set comes pre-bled but the frame I am putting it on has internal routing so will need a re-bleed.

pre-bled

This is a myth unless youre 6 foot 4. Cables are always too long so new barbs and bleed is necessary

are these the ones? you dont need DT swiss hubs for them to work perfectly?

yep I agree, although my road set didn't come pre-bled. Doesent make sense why Shimano would do it with MTB sets.

@svendhöek
Thanks for feedback. Think I can pick up a suitable Shimano adaptor on the way home, the first style with only two bolts.

@branwen
F & R on mine too.

Shall fit report back.

I think they figure that as so many road bikes that will have them have internal routing and need the lengths to be pretty precise with hose going under bartape and whatever that'll most will need trimming and bleeding. Whereas loads of various MTBs have discs and it's a pretty common upgrade and if it's vaguely close people will live with a bit too long hoses.

and what about the radvist road frame flat bar front rack builds?!!

Cantis.

you guise xxx

now I just hope diverge can take WTB horizons.

Yep. I'm pretty sure the only difference between mtb and road is the shape of the lever. I went for road. Just make sure to get the right length! Only disadvantage is it takes a bit longer to make a wheel change. Still quicker than bolt-thru though!
