Brake thread

[BolD_FacE]

Today my 1 month old Magura 2005 HS 33 Koxx Edition broke totally. The first day when I put it on my bike my TPA broke. I made it so that I could ride my bike normally, but today my cylinder (this part of the cylinder that is situated the pad - a small ball) broke off ... Well after all magura s*cks ... If someone asks me about this magura , I think - :umno: ... I was wondering what about putting Vee adapters ... and is there someone riding Vees with Echo pads + grind ... Please tell your opinions

[trialsn]

just do a search...there's tonnes of threads about using vee adapters and using different pads with vee brakes

[stinkybastard]

Funny how all these years only one company still produces hydraulic rim brakes for trials(correct me if Im wrong)

Just a brain fart, why cant they make a rim brake using 4bolt mag mounts but a mechanical system(not v-brakes duh), like removing the inner half off an avid caliper and mounting them on the frame w/ v pads

Youd have the benefits of a mechanical disc brake applied to rim brakes.

Drawing is crude, i know.
Hope you see what Im seeing

[Acolyte]

You mean, like Cantilever brakes? Center pull ftw?

It sounds like your brake had AIDS, I'd give it(or another HS33) another chance. I give every brake I use two chances. If it fails me twice, it's gone.

i see what you are saying, i have no idea how you could get it to work though

[muddyfox]

There was a company that produced hydraulic vees. Anyone remember those?

[Giant1118]

ya they sucked

[stinkybastard]

i see what you are saying, i have no idea how you could get it to work though

really it would be 2 halves of a mechanical db caliper, one rotated so cable pull would be forward.
cables could both meet under the toptube and merge together such as bmx.
instead of using small 3/16 bearings one would use larger bearings to give more throw w/ the pads.
-piston could even accept a magura pad:dunno:
heres a better picture, first one kinda blew.

[free_rideman]

Very good idea. That would be a very nice brake.

Just two things though. First you would lose a lot of power at the point where the two cables go into one, unless you figure out a better way of doing it than bmx. Two, would this be that much better than normal vees that are setup correctly? Just playing the devils advocate.

Anyways, still good that you are thinking, would be nice to see how well this design works.

great picture too.

Well I cant exactly think of a way to merge two braking systems w/out avoiding a "bmx" setup. If you compare the force exerted on say an avid bb7
caliper to a v-brake...I dunnno, this is merely an idea since i fucken hate maguras and like my avid bb7s. I too would like to know how theyd work

yeah they were called starbike brakes i think. santos had them on the front a looooooong time ago on his brisa.

heres a picture i found

I took some pictures of my broken cylinder today. Here they are :

I should have clean it ...

[MikeTheBike]

Call Magura. They will likely sell you just the one new slave cylinder. Also, be more careful taking the pads off in the future.

It`s not bacause I have taken off my pads uncarefully, it broke off while I was making a kick ... :dunno:

[tamu]

the reason disk breaks work so well is that the distance the pads travel compared to the distance the lever travels multiplies its power..

in or der to get the same kind of "squeeze" you would need to have a rim as true as your rotor (it rums if its like 1mm off...)

if you reduced the mechanical advantage of the avid disk break, and you could.. because the diameter of the rim is much greater than the diameter of the disk.. it might work..

but your best bet would be some kind of mechanical improvement onto V brakes instead of making something new..

basically all you need to do to V brakes to make them really good is make them have the same resistance and the same distance from the frame.. the thing is, you can already do this! just takes some work..

as far as your dual pull idea, that isnt bad at all, if you encased it in steel tubes.. there wouldnt be any more loss than there is in your brake cable..

speaking of that.. if you ran your cable through a metal tube most of the way, used a good quality cable.. it should eliminate most of the flex.. all you need in like 2 in of housing at the rear and maybe 1ft of housing at the front..

duno, but lets not reinvent the wheel here.. things have become a way because its tried and true.. not because nobody could come up with a better idea!

[rocpyro]

if you did the 2 avid thing, i think the best way to devide up the forces between calipers is to devide up the cables; have two coming from a special lever made for two cables. i still think that a high quality current system, properly set up, is more than enough power than one would need.

[stinkybastard]

I love this site, so many smart people to criticize a new idea JK
lots of people like maguras lots hate em...what about a system using the monoplized 4 bolt mount thats not magura, and cable actuated:dunno: ....not v's, I think it would be fun to use

[BolD_FacE]

hey what about this set up : Avid sd7 callipers, sd7 lever, Jagwire housing and echo vee pads + grind ?

[felix]

ok, except for the pads.

[ChrisB]

use heatsink pads instead of echo pads and that would work pretty good.

[BolD_FacE]

ok, 10x a lot

It seem impossible to buy heatsink vee pads in my country. I`ve herd a lot of good things about Plazmatic pads - would V-flys work good or I should buy some CRVs ?

[BolD_FacE]

I`ve read tones of threads since my last post and there was nothing special about this pads...Anyone who can help ?

[Sondre]

I was wondering what about putting Vee adapters ... and is there someone riding Vees with Echo pads + grind ... Please tell your opinions

I've used to run that setup for like a week ago on a grind...

I used:
Heatsink Adapters MK1,
Shimano STX lever,
Shimano LX brake-arms,
Cheap housing and wires
and the Echo red's : )

The setup worked brilliant! Decent lock and bite.. : )

Good luck!

Heres a quick thought.

Has anyone ever tried using a BMX brake lever on a V brake setup? Due to the pivot point being closer to the bar (or something like that), you get ridiculous power, but the system is mushy as fuck. The lever has so much power that it flexes everything in the system; arms, cables, frame, everything.

So what if the entire system was strengthened? Oversized CNC'd arms, a thicker cable, with metal housing (a la Nokon, or Avid FMJ), and metal backed pads, combined with a big mofo of a booster. If the mushyness was taken out of the system, you'd be left with the raw power that the BMX lever provides you, no? Someone tell me if I've gone totally bonkers.

[lucky13]

Has anyone tried setting up a magura properly? I bet your slave cylinder was too far away from the rim with a worn out pad resulting in a post snap.

Too bad you won't even try Magura's excellent customer service.

no you haven't you've got it right. With Avid speed dial levers you can reduce the lever pull almost to the level of centrepull/BMX levers. This makes the system, as you've observed, really mushy! To take out that flex would require a hell of a booster, and some serious outer cable. All more than the market provides.

However, I run a nokon housing and Shimano carbon booster and can have the leverage knob most of the way to the mushy/powerful end and still have a super-stiff rear brake by most standards. Needless to say, it's got a fair bit of power.

I serviced and therefore test-rode a bike the other day which had 1996/1997? shimano LX V-brakes on it - very butch brakes of which I am lucky enough to have a pair...somewhere... anyway, the bike still had the original long-levered shimano tourney cantilever levers. Super powerful. The pads had to be set up less than a millimetre from the rim to get decent lever pull. I was afraid to pull the rear brake on fully, in case I broke the welds on the seatstays!

10x all. I just want to ask a last question. Since my last post I`ve been thinking about that my adapters will make me lose some a lot of my braking power. Is that true ?
