Does anyone have a picture of how they have the finned set up on some sidepull calipers?

I scored a set of brake shoes (thanks Skip!) but the way I have them mounted on some Superbe sidepulls- it doesn't look quite right to me.


Thanks!

Cool!

so to speak.

The Golden Boy 

Thanks @KonAaron Snake - so you have the domed washers facing outward away from the shoe to the caliper arm, and then the domes facing inward from the caliper arm to the nut?

Si señor.

Have you seen what Drillium Dude does with these? It's spectacular.

The Golden Boy 

Thank you Aaron and Tom!

I know the fins were ostensibly to assist in cooling- but I think if you were in need of cooling to the point that fins on the back of your brake shoes would be necessary- I think you'd be kind of up the creek- as it were.

I think the fins just look cool as all get out!



Edit-

Just out of curiosity- can the pads on these shoes be replaced?

The Golden Boy 

No- what's going on there?

KonAaron Snake 

Mine are glued...no replacement

This is the dd treatment:

The Golden Boy 

ANOTHER question...

Are there 2 or 3 different kinds of washers?

There's the regular thin washer under the screw- and the domed washer, is there another washer that is like the domed washer, but not domed?







That's beautiful- the enamel paint treatment looks like it's supposed to be there and it "classes" up those shoes even more than they are to begin with!!!

Neo Finned ones are coming thru Merry Sales Imports .. replaceable inserts ..

Will they be available for the post type? These binders have worked extra hard but thanks to an additional rear brake (Arai finned drum) its helped in their longevity. Lots of choices these days but like the others here, prefer the 'cool' look

The hardware that came on these shoes varied over time.

As @The Golden Boy says, the cooling fins were a joke. The heat goes in towards the rim, not out through the pads.

No, you can't replace the pads. On the other hand, mine have been on my bike since 1983, and they're still working spectacularly well. Normally, single pivot sidepulls require a heck of a lot of squeezing to stop well. Not here.

The Golden Boy 

I've seen the black ones through Yokozuna USA.

I'm going to set up my Trek 720 with those and probably the champagne colored XC Pro Cantilevers. I haven't quite decided yet.

Thanx fietsbob and GoldenB- found them. Black anodized only, salmon pad. Threaded post part with washers/nuts part num. 70679 / non-threaded post num. 70676.


Gimmick they may be but win in the looks. Not fond of the black look but maybe if the top of the fins were sanded it would highlight the candy.

The Golden Boy 

Thanks Tom

The cooling fins at least look really cool. I guess you could say they offer structural tension to oppose the counter torque load that's brought laterally across the shoe's plane- resulting in a torsional advantage that allows for proper equalization.

Thats a drag about the pads, but from what I've read and accounts like yours- the pads are long lived and fantastically stoppy.

What I ended up doing is going shoe> domed washer facing out> undomed washer> caliper arm> undomed washer> domed washer facing in> small washer> nut.

One of the nuts was cracked and broke, so I replaced the front two with the nuts from the Superbe pads. Pictures shall be forthcoming.

fietsbob

Yea thats the Merry sales trade name 'Yokozuna' & Soma.. the company is in So SF

as name suggests another TW made products thru a USA importing distributor . .

The Golden Boy 

If you do that- post your results- the plain, flat aluminum look is the cat's pyjamas.

crank_addict

I just noticed the replacement pads for the 'Superbrake'. Could this be? Also noted is USA made.

dddd

Bonding a urethane pad to aluminum sounds like a job for a urethane adhesive, but one would be on their own as far as considerations of process, testing and quality-control.

Then there is also the matter of where the replacement pad material would come from.

I agree with The Golden Boy and think the fins are great from a structural point of view, adding the essential stiffness in the preferred direction without adding much weight. It can't hurt though that they also control the temperature where the pad is bonded to the "holder", and of course these look awesome!

As noglider posted, there are at least two versions of the mounting hardware, early ones had steel nuts, while later ones had large, alloy, convex-faced hex nuts.
There only needs to be a "ball and socket" on each side of the brake arm for the tilt adjustment feature to be effective.

The only bad thing about these pads, other than the bonding and pad-replacement issues, is that these (because they are good, urethane) pads don't really work right on steel rims. There will be melting and squeeling, and the braking modulation will therefore be abrupt and unpredictable.
I later put my nicest pair of steel wheels on this bike, and then had to change the pads back to the old originals:

The Golden Boy 

Hey D-

That looks awesome- what's with those shifters? They look really cool.

phoebeisis

Oh those older style Matthauser
ALWAYS look slightly WRONG
Because they are much longer than OEM
and they are STRAIGHT
But are on a curved rim
So "in the day" they always had a slightly "wrong but cool" look.
Oh the washers-gotta get them right-so they face the rim "just right"-
trailing edge touching first etc I think -
they need to be able to freely pivot so you can adjust them "just right" get good full contact
but someone else will tell you the HOW of that

But looking "funny" but cool is about right.They always looked that way-because they are/were long and straight.

The Golden Boy 

If you notice, the shoe is different- on the old aluminum looking ones, it seems the pad is bonded to a flat surface. With these, the pad seems to fit into a box holder on the shoe.


This brings up something- how many different variations of the finned shoe are there?

I see the "crude" non-finned aluminum shoe, I see the finned shoe with the pad bonded and then I see these black shoes that the pad seems to slide in.

I guess I'm wondering if the Yokozuna shoes are their own thing or reproductions of the last variant of the Scott/Mathauser Superbrake shoe. Or if the "Superbrake" name was for the black finned shoe with the replaceable pad.


The aluminum, threadless canti finned type




Aluminum threaded caliper type





The "crude" non-finned threadless aluminum type






The "crude" non-finned threaded aluminum type







Then the black threaded and threadless finned pads- listed as "Superbrake" on the BikePro page

These date from the early to mid-80's, I believe. IIRC (not having looked at them for a few weeks), they are curved. You can't see it from this perspective though. I could be wrong about that.

The Golden Boy 

You're correct, they're slightly curved to match the rim.

What bike are these on, Jim?
