Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

what is the real difference between front and rear brakes?

they look the same to me.
is there any mechanical difference?
would running a rear brake in front be bad for any reason?

as i understand it, it is not about the brake itself, but that they are attached. thick fork in front vs thin brake bridge in the back.

i've run a rear on the front by getting a reeeeeallly long recessed bolt. running a front on the rear would involve a little more work.

edit: this is for calipers. for cantis and v brakes there isn't any difference.

yeah, i've swapped the bolts out before depending on what i wanted to run. i just wondered if the bolt was the only real difference.

dirtyphotons, where did you find a recessed bolt that fit?

i had it laying around, most new brakesets come with several different length recessed bolts.

this is a perfect job for a lbs or bike co-op.

looks like you can order a titanium one online here but i'm not sure if it's long enough, and with shipping it's probably half the price of a nashbar long reach caliper.

Extra-long recessed nuts are made by Problem Solvers and may be found in the QBP catalog (that any LBS can order from):

I'm currently running a recessed rear brake in the front using one of these nuts.

For a vast majority of brakes there's no difference between front and rear. However, current high-end Campy road brakes feature a dual-pivot front brake, single-pivot rear brake. They call this a 'differential' system.

in the interest of weight campagnolo and shimano both now offer differential brake setups with their top gruppos..
they figure that the front brake does most of the stopping and therefore is the more important caliper..
makes sense i guess

i guess my point is that i'm glad there's SOMEBODY out there helping make parts work together, rather than manufacturing parts that only work with their stuff.

that they're just a brand name and owned by a big conglomerate is less of a concern.

The rear brake is your legs and the front brake...well, the front brake is both dangerous and not fashionable...I would advise against it.

Come to Bike Church on Sunday and I'll set you straight. Making frankenbrakes out of multiple sets is good times.

Damn, I wish I knew this a couple months ago - I just bought another set of calipers just for the front one, leaving me now with 4 rear brakes. But now I just need four of these bolts and I can set up four more bikes!

ha, i was thinking about the same thing yesterday. I got a set of brakes for my wifes bike but only needed the front. So I semi-took them apart to check the diff, and all the part numbers were exactly the same. The centerbolt was the only difference.

This is so blatantly false that it can only be a TROLL.
