customrider-Rhys Posted October 12, 2012 Report Share Posted October 12, 2012 Right basically i was thinking the other day about weather it would be possible to run both a disc brake and a maggie of the same lever on the rear, would be an awesome idea getting the best of both world, surely you would get minamal slip! then i thought that the echo discs use mineral oil aswell so would it be possible to use an echo lever run a feed pipe to a splitter then one pipe of to a maggie that has a joined crossover pipe (standard way) and the other pipe from the splitter down to the disc caliper? could it work or is it just the most ridiclous stupid idea ever?! if it could think how good it could be, the bite and hold of a maggie mixed with the hold of a disc, if one started slipping the other would be trying to prevent it allowing the other to bite again Quote Link to comment Share on other sites More sharing options...
Jake. Posted October 12, 2012 Report Share Posted October 12, 2012 Imagine how much the power would be spread? So no. Quote Link to comment Share on other sites More sharing options...
Ali C Posted October 12, 2012 Report Share Posted October 12, 2012 discs normally operate on a different mechanical advantage than rim brakes Quote Link to comment Share on other sites More sharing options...

Revolver Posted October 12, 2012 Report Share Posted October 12, 2012 If you have the money and other resources, try it just to see. I think it's be cool to see what the result is even if it isn't totally great. Quote Link to comment Share on other sites More sharing options...
chris13 Posted October 12, 2012 Report Share Posted October 12, 2012 it will work, But there will also be a LOT of travel in the lever before anything happens. Quote Link to comment Share on other sites More sharing options...
Maxx Posted October 12, 2012 Report Share Posted October 12, 2012 it will work, But there will also be a LOT of travel in the lever before anything happens. I agree. Pressure will be the same in all the hydraulic system so power in both cylinder / caliper will be the same as if they were alone, but you will get a spongier lever with a long travel.

Laurence--Trials Posted October 12, 2012 Report Share Posted October 12, 2012 you would need a big master piston. thinking about it i think the disc would lock up before the magura though. Quote Link to comment Share on other sites More sharing options...
Maxx Posted October 12, 2012 Report Share Posted October 12, 2012 Slave pistons (2 of magura and 2 of disc caliper) need to be in contact with rim/disc to brake : more travel for the slave piston = more travel for the master piston (at the lever) = more travel for the lever. A bigger piston at the lever would be ok for a good lever's travel, but you will have less power ... Maybe disc pads would touch the disc before hs33 pads touch the rim, but it doesn't matter, when you brake you just pull the lever to the bite contact (and so all pads touch rim/disc at this point) But this is only theory.

customrider-Rhys Posted October 12, 2012 Author Report Share Posted October 12, 2012 it would matter what locked up first, ideal the maggie which surely being closer to the lever would be first unless your pads are days away from the rim, but it wouldnt matter, if you were to pull the lever it would all just lock on together Quote Link to comment Share on other sites More sharing options...
Tomy P Posted October 12, 2012 Report Share Posted October 12, 2012 Change the piston in the lever. However, extra weight / more things to go wrong. Probably best to stick with one or the other properly set up. Quote Link to comment Share on other sites More sharing options...
Jake. Posted October 12, 2012 Report Share Posted October 12, 2012 Could easily try it with a trialtech hose splitter and route the fluid down to the disc too, the best way to do it is to get strong biting maguras with a disc that offers a lot of hold.

hypermobilty Posted October 13, 2012 Report Share Posted October 13, 2012 You could get them too both engage at the same time but you would have to change one of the internal diameter tubing for this We have lots of engineers on here if you know the leverage ratio and piston sizes in comparison to each other im sure some one can work out the sizes A problem I can see is the tpa as it would not work the same for each brake Quote Link to comment Share on other sites More sharing options...

Rockman Posted October 13, 2012 Report Share Posted October 13, 2012 Or set up a disc or magura so it's amazing and not worry? None of my brakes slip at all.. Quote Link to comment Share on other sites More sharing options...
rocky111 Posted October 13, 2012 Report Share Posted October 13, 2012 (edited) I don't know off any frames that have both maggi and disc mounts, so unless you got one made or welded on then not gunna happen for rear. you could try with front though as the others have said I doubt it would work very well at all, cant beat a good brake that's set up correctly. Even if two was as good, they would be heavier and more expensive plus more to set up/go wrong. Edited October 13, 2012 by rocky111 Quote Link to comment Share on other sites More sharing options...

FamilyBiker Posted October 13, 2012 Report Share Posted October 13, 2012 as maxx said,both pairs of pistons had to be contacting the braking surface(at the same time),before any!!! braking force is gonna be there. in a system wich lives from hydraulic pressure,think that over.where would that rising pressure come from,when either maggie OR disc pads touch ground? you´d have a brake that shifts the first pair of pistons out,they touch the braking surface,then the hydr.pressure would first shift the second pair out,THEN brake force would be applied on both pairs with rising hand force. nope,doesnt work with a normal brake lever,but: check this out: http://go.mtb-news.de/redir/clickGate.php?u=RN1hJwP9&m=1&p=2YPGEU221K&t=z245JY2e&st=&s=&splash=2&url=http%3A%2F%2Fwww.pinkbike.com%2Fnews%2FReality-Redesigned-The-GAUNTLET-Ep1-HM-12.html&r=http%3A%2F%2Fwww.mtb-news.de%2Fforum%2Fshowthread.php%3Ft%3D519145%26page%3D7 Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted October 13, 2012 Report Share Posted October 13, 2012 It probably wouldn't make a huge difference on a trials bike (and considering it'd feel shit anyway) but don't forget that most discs run open systems where as an hs33 is closed too.

FamilyBiker Posted October 13, 2012 Report Share Posted October 13, 2012 julie 05 is closed system compatible,running one myself on a hs 33 lever.works good. but thats the only low pressure disc i know Quote Link to comment Share on other sites More sharing options...

FamilyBiker Posted October 14, 2012 Report Share Posted October 14, 2012 yeah,it applies pressure to the first pair of pistons until a defined(dont know if its adjustable?)amount is achieved,then opens a second port wich brings pressure to the second pair of pistons,while keeping the pressure at the first pair. thats the idea, i didnt try it though,dunno if it actually works Quote Link to comment Share on other sites More sharing options...
SamKidney Posted October 14, 2012 Report Share Posted October 14, 2012 Meh. Just set up a rim brake or disc properly and they will both work fine. Less weight, less hassle, looks nicer, feels nicer. Quote Link to comment Share on other sites More sharing options...
