Shimano Deore disc brake pin
I have a Boardman Hybrid Pro which has Shimano Deore hydraulic disc brakes (M615 calipers).
I've not had disc brakes on a bicycle before so some things are new to me. I noticed that the pin that holds the pads in place is bent at the end to stop it moving out of place. This means I have to straighten it to remove the pads and then re-bend it when placing it back into position. This seems to be a poor solution to me as I anticipate the pin eventually breaking through metal fatigue.
On motorcycles I've owned this pin is usually a rounded bolt with a hole drilled through the end that takes an R-clip.
Is the Shimano pin supposed to be replaced at every pad change? Can you buy it separately?
Here's a photo to help clarify what I am talking about.
Cheers for any help!

i wouldn't worry about metal fatigue in the pin, it should manage many straighten-bend cycles, if it gets tired you can just replace it
shimano part Y8DB06100, or measure the old one and buy genericmy bike - faster than god's and twice as shiny0 -
Many of the replacement pads come with a new split pin or, as above, you can use a generic one.
Other manufactures use a threaded pin0 -
Looks like a regular split pin, you can re-use them, you are right that they do fatigue eventually with repeated opening and closing, for peace of mind replace when you feel it is necessary and/or when you replace the pads. Some will say replace with a new one every time you remove the pads.
Go to an engineers merchant or fastener specialist and buy them in bulk, should be cheaper than buying in packs of 2/4.0 -
it is a rubbish solution though, I think shimano do it just to make more people buy XT brakes, I'd be happy with my deores if not for that split pin0
-
It's a series-specific thing. Deore XT and XTR have a threaded bolt with a retaining clip.
I've never bought new genuine Shimano pads for my Deore XT-equipped MTB and not got split pins too, so replacing the pin when you buy new pads shouldn't be a problem. Can't speak for other brands such as Clarks though.0 -
i used a tap to thread the first part of where the pin goes so it accepts the normal shimano threaded brake pin with clip. Easier to service then0

Is it? It's a very simple solution which isn't going to sieze up and the replacement will be readily available in local shops for the next five centuries! Just because it isn't pretty doesn't mean it doesn't work for me.
If the bending bothers you, you don't need to put anywhere near the kind of angle as shown in the picture. It just needs enough of a bend to not be able to drop out - and that isn't much at all.Faster than a tent.......0 -
These pins are used on thousand and thousands of bikes all over the world without a problem. They can be re-used and re-used no problem. Once pulled out just straighten them out in a vice - easy peasy. As someone said above a simple practical solution0

no one takes pliers with them on a ride, everyone takes a set of allen keys, I know which is more practical
plus on a new set of brakes I had the factory fitted pin was so short I couldn't even grip the end with pliers, it wasn't very practial getting that out either0 -
^^^ yup, prefer the allen key fitting for this reason when out and about0

I can pull my pins out without pliers - they barely need any rebending at all and certainly nothing that can't be done with a multitool flat blade screwdriver. Like I said, a 90 degree bend isn't necessary.Faster than a tent.......0 -
doesn't sound very secure to meI can pull my pins out without pliers0 -
Doesn't need to be as there is no force pulling on it in use. It just needs enough so that it doesn't fall out with vibration.

I've never seen a customer round off a split pin...0

I've never seen a sundial run out of batteries, but I'd still rather have a watch0
