Good day. Can anyone share personal experience regarding brakes? I’m building a Cotic Rocket and I plan to use it for a bit of everything, so want powerful brakes to make dh runs less fatiguing. At Cwm Carn I get exhausted quite quickly, largely due to arm pump from pulling on the brakes so much.
My current brakes are 2007 LX m585, changing to a 203mm rotor up front made a big difference but I still want better. And the new build is a lot heavier than my old bike.
So I’m thinking maybe Hope M4 Evo front and rear or perhaps M4 front X2 rear. Unless you can recommend something else? Winstanleys is the cheapest place I can see them so far.
Anything Shimano make. Saint for ultimate power probably.
The [url= http://www.bikeradar.com/mtb/fitness/article/how-we-test-hydraulic-disc-brakes-24345/ ]Bikeradar dyno tests[/url] (to which I was referred on another thread a few days ago) suggest that Hope Evo M4 and V2 have the edge over almost everything bar a couple of Formula brakes, though at a slight weight penalty over Shimano.
If you're going for Hopes, what about a vented 203mm V2 up front for complete overkill? 😛

I had assumed the V2 was less powerful due to it being a single piston, they look cheaper on first glance too. Might give the vented disc a miss though, I like the complete overkill, would look good cycling down the canal, just a bit pricey!
I saw a post on here last week, linked to a review, that suggested the new saint brakes aren't very good if you need to adjust the levers for short fingers. I have short fingers, so that put me off.

fit new pads, clean your discs, stop using spray lube.
i know my advice is not very exciting, but it's what i'd be trying before i spent £300 on some new shiny brakes.

more pistons = more power = a myth (but they do look cool 🙂 ).
The Race Evo M4 are really great but if you're running 183+ rotors then I'd be tempted by the V2s.
V2 are the f'me i need to stop the wheel turning brake, the vented discs are more for alpine/serial brake draggers
The Tech M4's are great (one before the evo) plenty of stop, plenty of feel and adjustment.
Fitted for 18 months no issues. Last set of M4's (original) are still going at 6+ years old.
cheers, the brakes are in top working order, just not up to the job of dh
Yes it will be effective piston diameter, the V2 has a huge piston it seems.

This is good to read.

Why is that chief?
looking at the bikeradar test the Shimano SLX M666 is only slightly under the Hope and only £60 from bikediscount de.
Anyone used the Shimano SLX M666?
You can't run the V2s with smaller rotors - if you're running big rotors already there's practically no weight penalty for the V2s vs the M4s and if you're downhilling why not enjoy the extra power?
why not indeed
I've had V2s (the old Moto)fitted to my Five for the last 4 or so years, and they have been faultless. I dont do DH but ive used them in the Alps and they have plenty of power, good feel and have never overheated.
I built up a BFe last year and thought about fitting M4s, but in the end opted for the Tech V2s, as i have found that two pot brakes have less issues with "sticky pistons" than four pot brakes. No regrets. More than enough power for one finger braking. Great feel. And lots of bite point and lever adjustability.
