Tektro Volans brake pad pins?

[LittleWheelsandBig]

A friend in Oz has Tektro Volans disc brakes on his ICE Vortex. Apparently he is missing a brake pad pin, totalling about 28mm long including the head, and wants me to chase up replacement pins. Perhaps his local shops are useless or perhaps such a thing doesn't get out to the Antipodes.

The pin looks a lot like the disc brake pad pins on HK's Shimano hydraulics but I've not put a tape measure against them. I've been able to find plenty of sources for replacement pads but none for replacement pins.

Please point me in the right direction.

Are the pins on the tektro structural or similar to shimano there to prevent the pads lifting out (had that happen when I lost the pin midride)
If the later, the shimano cheap way is a suitably beefy split pin. (It's even in the lower spec brakes tech docs)

[LittleWheelsandBig]

The pins look identical to Shimano's, with a short thread near the Allen head and a circlip groove at the other end.

That sounds almost identical to the pin on my ultegra discs. I do not have a part number to hand

[Deano]

Wouldn't the pin come with the pads?

[LittleWheelsandBig]

Not in the photos I've seen but the springs do.

Might be worth getting in touch with ICE. They’re pretty helpful

Y2EN98010 Pad Axle & Snap Retainer is the beastie, provided they are the same thread (likely) and length (perhaps not).

I'll chase up with ICE but may just buy a Shimano set in the hope that they may fit.

note that in some models of shimano brake it is possible to use either

a) a fancy threaded pin with a retaining clip at the end or
b) a split pin

in exactly the same brake.  This option is shown on the EV techdoc for several different shimano brakes.


Thus I'd suggest that if the tektro brake is made in the same way, a split pin ought to be an effective substitute.

Split pins are of course readily available.

Split pins are, of course, a bit shit though.

Is this what you are looking for ?

Description notes Tektro as well.

28mm long sounds like the thing needed. Thanks for that.

Split pins are, of course, a bit shit though.

they are arguably a lot less trouble than the fancy threaded pins in bicycle brakes; they don't seize into the caliper body, they never need to be drilled out, they don't lose the retaining clip for no good reason, they don't fall out of the caliper spontaneously, you can buy them very easily, and you don't need any special tools to fit them.

The split pins that are used on bicycle brakes are arguably overkill for the application.  I note with interest that the pad retaining split pins on a well-respected vehicle - which can have when towing an all-up weight of about six tonnes- are 3/16" on the front brakes and just  5/32" (about 4mm) on the rear brakes. These split pins are also a lot longer and easier to bend, when compared with the diameter.  By comparison pins of ~2mm diameter seem more than strong enough on a bicycle brake.

As well as generic parts eg from a motor factors, Shimano use two different split pins in their brakes, and you can buy them (any shimano dealer) separately.

Split pins are still shit though.
