makinshaw Posted September 28, 2015 Posted September 28, 2015 Just bought myself a new SC Tallboy but the brakes are the wrong way round - I'm used to the UK system with the back brake on the left, front on the right. The bike shop have installed them the other way round. If I want to swap them around can I simply remove the hoses and swap them over, or do I need to do a full bleed? The brakes are Deore XT - latest version. Any advice would be much appreciated. I'm a roadie who's just started with a MTB so hydraulics are new to me.
Popit Posted September 28, 2015 Posted September 28, 2015 Can you not just swop the complete lever and hose ??That is what I did .
rouxtjie Posted September 28, 2015 Posted September 28, 2015 Well if you want to swop them you would need to extend one line and cut the other...both cases will need a bleed.
rouxtjie Posted September 28, 2015 Posted September 28, 2015 Can you not just swop the complete lever and hose ??That is what I did .yes this is what I meant...but again, would need a new olive and a bleed...both sides
makinshaw Posted September 28, 2015 Author Posted September 28, 2015 Thanks for the advice - much appreciated. Now to find out how to bleed brakes properly!
Wannabe Posted September 28, 2015 Posted September 28, 2015 Can you not just swop the complete lever and hose ??That is what I did .With Avids it is as easy as that.Do not know if Shimano allows it.
rouxtjie Posted September 28, 2015 Posted September 28, 2015 Thanks for the advice - much appreciated. Now to find out how to bleed brakes properly!XT's are quite easy..it might be worth it to just take it to a lbs and let them do it for you...they will have the olives and shimano mineral oil as well as the equipment.
patches Posted September 28, 2015 Posted September 28, 2015 Naught Boets! They're Shimano XT. They're the best brakes in the world and never need bleeding! But really, they can be swopped without bleeding. I've seen Jason at The Trail Head do this on test bikes when a customer rides with brakes the WRONG way around. He simply disconnects the hoses from the levers (while everything is still on the bike), making sure the open end stays as high as possible, then reconnects. Obviously over time, if one keeps doing this, the air introduced into the system will require a bleed. But for a once off, it works.
NotSoBigBen Posted September 28, 2015 Posted September 28, 2015 Why not just unscrew the hose at the lever and swap them around? I have been led to believe that in 90% (you know what they say about statistics though) of cases if you're careful it will be fine but in the worst case a bleed would be needed. No salad ingredients and cut hoses and stuff surely?

No salad ingredients and cut hoses and stuff surely?I wanted to add that...should work if you are very carefull. No cutting needed indeed

Paul Ruinaard Posted September 28, 2015 Posted September 28, 2015 If you just swap sides the master cylinder with current generation XT brakes (M785 i think) will be upside down. Not a good thing. Fluid flows downhill, so eventually you will run in to issues. You have to swap hoses around and keep the levers in place, and as Brakes are hydraulic - there needs to be no air in the system as it is compressible where fluid isn't. If you open them up then air gets in - you have to bleed them. Take it to your bike shop if you haven't done it before - its easier and less messy.Shimano uses mineral oil not brake fluid BTW and you can't interchange it with normal brake fluid cause the seals will get destroyed. If you want to bleed them yourself then you will have the bets results when you take them off the bike and simply gravity bleed them. Just google 'Bleeding Shimano XT brakes"
dirtypot Posted September 28, 2015 Posted September 28, 2015 8mm spanner is all that you need.It's not complicated if you're careful.
