Need some help from the homebuilders here. I have built a TE clone and am running 20" front and 26"
(559)rear tires. Got some Odyessy brake calipers , that run on many older freestylebikes,and and set
up the frame / forks for them. Front brake works like a charm. Super braking with it.

But the rear is a sad story. It would only slow the bike. And not slow it a great deal. Will not
slide the rear wheel even in the dirt. Dragging your feet is much betterthan using rear brake.

So, I put a "Bulldog" caliper on the rear. I these are Dia-Compe.

Like these. http://www.cyclepath.ca/products/itm00034.htm

Readjust everthing and same story. Both of these calpers are well made, beefy construction, that do
not apear to flex ect. And as I said, the front one works great.

Dug around in my parts boxes and found a no name steel caliper that came off an old Murray comfort
bike. Installed on the rear , adjust ect. Now decent brakes , but not great .

I used cable stops on the frame to cut housing length to a minimum. So , I do not think housing is
compressing . Good Dia-compe pads that have been successifully used on other projects. Pivot bolts
lubed, brake pads properly toed in . The pads are in the center of the adjusting slots on the
caliper, not out at the ends. I have put the same Odyssey calipers on a custom cruiser of mine with
good results.

My question, what gives? Any help would be appreciated.

Thanks

Yes, sidepull single pivot caliper brakes. Like I said , the front works like a champ, but the rear
is doggy. With the steel sidepull caliper, it is reasonable, but nothing like the front.

Question, does the nylon/plastic lined cable housing compress more than the old coiled type cable
housing. This is the first time i have used it.

I am going to try a lever change . But has anyone had this problem or am I just lucky today??? I
hope I'm not real special in this regard. Again, any help would be appreciated.

Thanks

I think you are on the right track. That looong stretch of cable housing going to the rear brake can
be problematic. Braze ons that allow a big part of the cable to run without the housing can help.
There are also"dual pivot" brakes that mount just as a regular caliper brake, and there is some
improvement. Tektro and Shimano both make them. I have seen them on sale for less than U$20 before.
I need one right now, and haven't found as good a deal as usual, but here is a link

hopefully somebody will post a better one. rorschandt
