Cane Creek SCR-3 dual pivot brake question....maybe most brakes. ..

I bought 2 of these for 10 bucks; both front brakes. Is my thinking right? If I reverse the pads and shorten the pivot bolt I create a rear brake.......right?

have a thread cutting die? may help in your goal, thread the center bolt further *
*machine shop tools..

you may also use a plain nut and spacers to pull the
longer bolt tight enough for the rear fitting..


there are kludges.. and work-arounds..

The thread almost certainly doesn't go far enough.

Looks like a brake upgrade for two bikes to me. A dual-pivot on the rear is almost always overkill; any nice single-pivot is more than enough.

Depending on your toolset, it may be cheaper to replace the mounting bolt as opposed to cutting it.

If you're cutting the bolt, thread a cutting die on BEFORE you cut. Then when you back the die off it will repair the threads damaged by cutting. If you don't have a die, use a STEEL nut and cut with a dremel, then grind the end to round to taper slightly.

The brake can be fully disassembled in about 5 min, so if you can find a rear mounting bolt, I'd recommend just doing a swap.

Yes. Be sure to dress the cut bolt to prevent cross threading.

Recessed mount rear brakes need to be threaded almost all the way to the shoulder. Most front brakes aren't and so you'll run out of thread when using the recessed nut.

An easy fix is to drill out the recessed nut to 6mm so it slides on over the bolt, and use a regular normal 6mm nut behind to mount the brake.

Threading the bolt is also an option, as is buying a rear bolt, but threading can be problematic since most bolts are too hard to get good resuls with normal dies, and a new rear bolt will cost more than the brakes.

I just put a regular nut and a flat-washer under that Nut to fit brakes on a recessed bolt frame .

if the nut bottoms out before the brake is tight on the frame, add a thicker or More Washers.

star lock washer between the brake and the Back of the frame will keep it from rotating
coming off center , as you apply the Brakes .

Can you rob the shorter bolt off the brake you are replacing with the new brake?

Only if these brakes aren't an upgrade, ie the other brake is a dual-pivot.

I did pinch a mounting bolt from a Tektro and successfully used it in a Shimano brake; I remember being happily surprised they were virtually identical.
