If you've got a set of XTs, take the contact point adjustment screw right out and tell us what you see in there.
 
I've had Avid, Formula and Shimano in the last few years. I've had no reason to change my Shimano XTRs since I bought them. Light, powerful, great modulation, super easy to get pads for.
 
I've had Avid juicey, elixir, and code brakes. I've had hope v4 and x2. I've had shimano XT, depression, and slx...

Shimano is by far the easiest bleed. And that "far" is a very big far.


Hope feel the nicest out of all and look the sexist. Their adjustments also work better.

Original Avid codes were a lovely brake.
 
Avids just aren't for the home mechanic and take a bit longer to set up. I rode a few demo bikes with XT and XTR, all of them had a sticky piston and the lever feel was horrible. I don't call a sponge lever modulation. If I had the money to blow, it would be Hopes and then top of the line Formula :behindsofa:

I've had Elixir 3s that were at the end of their life, they had all the standard (and some not so standard) Avid issues, I also have a pair of Elixir Rs that've been strangely flawless. Currently I've got XT M785s and SLX M675s that feel great and Saint M820s on the downhill bike that don't. M820s with inconsistent lever feel appears to be an extremely common issue, as schmity said, there's probably air buried deep in the caliper.

I've also shuttle road tested a friend's formulas and hated them.
 
If you've got a set of XTs, take the contact point adjustment screw right out and tell us what you see in there.

I've disassembled M785s to see how it works. IIRC The screw sits against a hinged plastic part that pushes on the back of the master cylinder.

It does work (as in it does what it's designed to do). It's just naff at how effectively it works.
 
I've got Formula RO's that I absolutely love and have had zero issues. Plenty of power and excellent modulation.

Guide RS on the Povo Rune have been problem free as well and also have good power and feel. Used to have Zee's but they were not so good. Lever pump issues and pad contamination through leaking seals I suspect.

Have run Elixir 5 without issue also.
 
You seem to have way too much time on your hands dude ;-)
Are you bed-ridden or something......

XT & SLX are pretty much the same.......google it.
I've read so much negative about Avid & so much positive about Shimano.
I have Shimano & love it. Would highly recommend.
Cheers, Daisy

The reason I tend to go with XTs is that they come with fined metallic pads which the SLX don't tend to.

And the bolt that holds the pads in place is nicer than the split pin.

I like shimano, they work well for the price, I bleed mine once a year, they have handled 1500m vert descents with out fading.

Rode a new set of guides the other day, demoed a nomad on a trail I know well. They lacked the power of my XTs and the lever feel didn't do it for me. But a few of the guys I ride with love them and hate shimano. So it's very horse for courses
 
Has anyone ever used a Paul Components Klamper? I'd be interested to hear how they go. Boutique component for sure; $200 an end for a mechanical disc caliper ain't cheap.

Interesting. With mine the screw position was making absolutely no difference to the contact point and when I took it out there appeared to be nothing behind it - meaning that it was a scam. Eventually the frustration with this lack of adjustment and always having the levers with wildly different amounts of throw (no matter how I bled them) is what me go back to Sram brakes.

It's a black plastic part. Unless you pull the lever off you want be able to see much.
 
The XT is excellent value for money. For ~$100/end you can't find a better brake. You can save a few bucks and get similar rest from the slx, but the XT reservoir cap is significantly series. *snip*
So if you can find them...buy them. Otherwise save some coin and buy the slx brakes.

They have been replaced by the M8000, yea? So I'm assuming, its a matter of only finding a secondhand set of M785s now.
Haven't had much luck finding a complete set online anywhere.

*snip*

Haha, yes at the moment I do actually!
I think I'm also a little bit of a research junkie and love hearing peoples first hand experiences with parts.

Just did a survey of my garage (way too much effort, seriously you must have too much time on your hands):

Shimano Saint

Shimano SLX (was running Formula but bike is for sale so back to SLX)

Hope Mono Mini Pro

Hope V4

Formula Oro Bianco

Formula R1

Avid V-brakes

And how would you rank them? Quite a collection of different brakes there, are there any standouts/duds amongst them in your experience?

I use Shimano because they just work and they're easy to work on, on the rare times that you have to change hoses or levers. I've only had to bleed a set once out of the 4 sets I've had in the last 10ish years. Much less fuss than dot fluid.

At the moment I'm running old Saint M800 (didn't even make the list!) with Straitline levers on the dually and XT M8000 on the hardtail.

The difference between the 2 sets is pretty significant! The Saints just won't die so I've had no need to replace them.... Also running 8 inch rotors front and rear on both bikes.

How do the M8000 compare? From what I've been reading they're not quite as trouble free as their predecesser (M785).


Currently got guide rsc's and they were awesome but now they are slowly shitting themselfs and are just getting me by. The guide ultimates have apparently fixed the issues with the other models.

How long have you had them before they began shitting themselves?

Nice link, cheers!

I've borrowed a mates bike with Formulas (cannot remember model) and I didn't think they were that much better than my current Hayes and its sort of put me off them unfortunately, as I guess it could of been the pads he is using or they may need bleeding.


I'm interested to hear from anyone who has upgraded from M785s to M8000? As the more recent the ride threads became it also became apparent the more that M8000s were being used.

Also off to search what the difference is between Dot and Mineral oil, seems like quite a decisive factor as well.

I can't compare the difference between the 785 & 8000, I've never used the 785s.

The difference between the 800 and 8000 is vast in pretty much every way. I'm using sintered pads in both and the 8000 have more power and more modulation. You'd hope so too with about 10 years give or take between the releases...
 
Running both at the same time (2 of each). I think the 8000's have slightly more power than the 785's....but I still prefer the feel of the 785's.

You mean like this?

You don't mind a black/silver combo? If so:

Seems they are out there, but getting scarce.

Those ones from merlin still work out to be a black silver combo.
I was recently trying to find a pair of same colour ones and couldn't.
Ended up getting the SLX 675 ones from Evans cycles for $128 for the set. Bargin, and I am very happy with them.
Previously had Elixer 5s and sick of the cost of getting them bled by LBS. Shimano I can do myself so they will basically pay for themselves in 12 months.

You're gonna have to start putting a trigger warning on these posts so the Shimano haters stop "sour grapes'ing" about your superior brake choices.

They've already paid for themselves because you only need to bleed Shimano brakes once.
