Anyone know anything about disc brakes?

Bb5s and bb7s I've had are fine with sram leavers.

Allegedly

Or your fine is less than my fine.

You are welcome to try them? I still have them hooked up on my airnimal.

Try mine and it'll feel like those fancy Shimano hydraulic.

Are Shimano pad axles generic? The head of the screw version on my CX75 is made of cheese and the allen bolt ones seem preferable.

Road BB7 and Sram work fine for me, as do MTB BB7 with Tektro drop bar v-brake levers. Set up was a little fiddly for the first time, but once dialled in, it's been fine.

I have used road discs for 5 years, many of them... Shimano, Avid, TRP, Hayes... I find many comments on this thread completely surreal.

IMO 90+% of problems people experience are down to bad installation. When properly installed and maintained, they are all above average, as brakes go

We can only go on our own experiences. I invested far more time and money in trying to get BB7s set up than was healthy. New pads. Compressionless cable outers, squaring off the ends with a dremel, everything that's been recommended on here.

They'd work beautifully then. For about 45 minutes and then it was back to rubbing pads or no power or something else. Far too much hassle to persist with basically.

The Spyres I have now, on the other hand, do work well and, most importantly, don't need constant adjustment.

And how are your Shimano hydraulics compared to both of the above?

I am amazed this debate continues, there is a clear hierarchy of performance and ease of maintenance.

do you have hams for fists andy ?

For everyday riding I'm inclined to agree. For racing off-road, it's a case of whatever is light, works and easily repaired, and in my own experience mechanical discs are more resilient to my maintenance regime than hydraulics.

A class apart, obviously.

Trekking I might consider mechanicals but 3 sets of XT hyrdaulics have worked near flawlessly, one needed bleeding after 3 years of use.

How much lever throw is expected from bb7 road brakes?
I am using sora shifters with shimano cables.
It is quite a bit but they is a lovely bite in the end

Change housing to compressionless then it'll feel much more positive.

Have you set up the pad adjustment properly? Excess lever movement usually means too much pad / disk gap.

Also the rotors need to be straight. move the fixed pad in so it just clears and thenadjust cable tension to get the moving pad to just clear. Tektro spyres are easier to set up.

Pads are set up as close as possible with out rubbing.
It is my first experience with disk brake and I am too use to the throw from road brakes

Looking at disc brakes for a new build(kaffenback 2 by the looks of it). Disc brakes seem to be more hydraulic than mechanical when I'm looking at shops unless I search road specific disc brakes and then it brings up some calipers that have different cable pull to work with sti levers.

Any reason not to just fit usual cable mtb ones? I'm going flatbar and fitting mtb gears already by the looks of it.

If I do fit mtb ones any reason to then not go hydraulic?

If I do go hydraulic what brands are best for bleeding and stuff? Are any just better to avoid at all costs? I'm thinking sram elixir 1 kit as it's cheap?

Go hydraulic for def , and Shimano get a lot of good reviews for mtb. Reliable, powerful and easy to maintain.

Shimano mtb brakes are so good and so cheap.

For a fiver more get the SLX though.

I've got issues with my hope minis, would I be able to run SLX with the same rotors? For 180mm rotors would I need a bracket/adapter or anything to mount the calipers?

I was looking at this as an option.

I'm just not sure about hydraulics, seems like a sure way to get chucked over the bars...

I've never owned avids, but based on what I've read on the internets, I would say they're probably cheap for a reason.

The shimanos get rave reviews.

Hydro brakes make a lot of sense, mtb cable are plenty powerful though , difference is you've got cables to maintain and pads to adjust, hydro you fit and forget until the pads wear out.
