Hydrolic Brakes; question....

So I just bought a Trek 4600 off craiglist.It has hydraulic disc brakes. So awesome.


...but for whatever reason they're on the wrong sides. The rear brake is on the left and vice versa.

My question; in order to switch em' around am I going to have to disconnect and bleed these bad boys? I'm assuming the answer is yes.

They're sr suntours. They stop on a dime but I've almost killed myself twice with them swapped around like this.


*At least I spelled " hydraulic" correctly IN the post.

I'll bet the previous owner was either european or rides motorcycles. Front on the right is quite european and as a motor cycle rider I like to have all my front brakes on the same side. And since swapping on the motorcycle is not an option I swap all my bicycle brakes around.

Some levers can be flipped but others require you to swap the lines. I've done this a few times now because I prefer the front to be on the right just like my motorcycles. What I do for this is to take the levers off the bars. I loosen the fittings while holding the lever so the line comes straight up. As the line comes free flip it up right away so you don't lose any or only a drop of the fluid. Now balance the lever in something that'll hold it open end up and tape the line to the bars or use something to hold it open end up as well. Do the other lever the same way. Now using a syringe or pointy fluid bottle make sure the ends of the lines are full right to the top with a little meniscus bubble of fluid on the opening. On the levers fill the ends up the same way. Now take the lever and the "other" line and holding them close to each other smoothly but quickly upend the line into the excess fluid of the lever. Once the end of the line is into the fluid you're safe. Just don't fumble it so the line pops out. Screw the flare nut down semi tight so it won't leak but that you can still twist the line in the lever, wipe off the excess fluid that ran out and hold the lever as it would be on the bar and twist the line if needed to make for a smooth run. Now finish pinching the flare nut tight.

If you did that right you don't need to bleed the systems if they didn't have an air bubble in it before.

Your brakes are on the right sides, if you swap them around they'll be on the wrong sides.

Only if you think like me or live in Europe. In North America the front normally goes on the left side.

Front right let's you use your stronger hand on the more important of the two brakes. Leave it alone.

I'm used to riding my mongoose cruiser. http://bmxmuseum.com/bikes/mongoose/35533

Don't know if it's the "right way" but it'd be more comfortable for me if the rear brake was on the right.

Youse guys who are saying 'rite' or 'rong' is all JERKS!!! Let the poore guy setup hiz braeks like he want's em.

FWIW, some hydraulic levers are completely symmetrical and reversible... you can just flip 'em side to side and not worry about anything. Most will require switching the lines, tho. Try BCRider's suggestion and if it doesn't work out you hav to have them bled, which would have been the case anyway so you lose nothing.

Good luck!
