Hello all,
Had a bit of a search but no luck...
Thought I'd do the brakes today, lovely day for it.
Front, no hassle, new pads, cleaned it all up, bit'a copper grease here and there, flying along.
Quickly do the back one and away to the shops...
First the little cap hiding the retaining pin would barely budge, lot of penetrant and eventually the little f'er came out. Pin, next, well, after a lot of penetrant again and being very carefull not to round the allen head with a good quality allen key, guess what, I rounded it , and it won't budge...
What to do next...how to get the bugger out? Ideas? :oops:
with the caliper off you should be able to get a grip on the pin with some vice grip pliers , in between the pads
and if that doesn't work how good are ya with one of these

the only Idea I can think of, is remove calliper and try and fit a long nose vice grip pliers and try turning the retaining pin from pad side, the pin is already knackered. or possible try using a torx head slightly bigger than the allen head, you will need to hammer it into the pin, and try turning, or a screw extractor, you might need to use an impact driver.
but I would soak it again and again with plusgas

Tried that one, man it's welded in solid, everything gives but the pin...
Drill and extractor next grrrrrrrrr, might try the vicegrip method but can't see it giving in that way...thanks for the input lads...
have you tried tightening slightly this might dislodge the pin. it sound strange, but sometimes this work and breaks the seal.

Yeah, did that, even the little tap with the "persuader" to "scare" it as we used to say had no result. Tried a 0.5mm bigger hex as well "forced" in there but everything just spins round in the end, don't want to damage the caliper so off with the whole thing and in the vice.
I was even surprised at how tight the little cap was in there, I literally had to use a screwdriver and a hammer to coax it out. It has that white oxide dry look in there as if the two metals are chemically welded together. Not a great day for giving up the smokes... :D
Hi BL, this is a common problem, I had mine do it too, and tried all the stuff already suggested here. But Mustang's right (as usual).
Get the whole thing off the bike and held solidly in a vice. measure the diameter of the pin (I can't remember it offf hand) and put a drill that size through first. The rounded out allen head will guide you well enough, just take your time and keep it in line with the pin, don't wander off. That'll shear off the pin and let you get the pads out of the way. Next you need to go through with a drill just smaller than the threads (measure the size of the root of the thread on one of the front pins and go next size smaller). that'll clean out most of the seized thread and often loosens it enough to spin the rest out. If it doesn't, lastly put a tap through it to clean out the threads. If you're unsure, a machine shop wouldn't charge much to do this for you, it'll only take five minutes.
I'd be happy to do it for you if you were near enough :wink:
Cheers BB, I'll be over in a wee minute lol, if only. I've got a buddy with a far better tool collection than I will ever have and he has one of those column drill yokes. If we could manage to get the caliper on there it should make light work of the wee pin...
I'll let you all know how I progress...
Ps. I'm about to fit the female metal fittings to the tank, does this mean the tank needs to be completely empty or would it work with the tank on it's side if there was half a gallon of petrol still in there? Read the whole write up but no mention of tipping the fuel...
Those little "grub screw" caps - My big screw driver always slips out of the slot when I try it, which reminds me to use the impact driver. One little tap and they're free. I always use Copperslip on the caps and pins when assembling too.
When you've got the pins free, don't even think about about doing them up tight when assembling; just an ever so eeny-teeny nip will do it, but lighter.

I think i'm starting to get introduced to the "over engineerd" part of my Triumph ha ha. My previous bikes has these pins as well but after removing a clip or something they could be removed by hand. Never needed an impact screwdriver before to change brake pads lol.
There's going to be plenty copper slip used putting this baby back together. I've been carefull tightning the pins as you suggest, they're not going to fall out I don't think.

Well, to be fair to Triumph, the brake calipers are Nissins. The hidden head of the pad-retention pin is slightly better than that in the Tokico calipers some lesser Suzukis use - not hidden and split pin to retain them.

Touche mon ami...I'll forgive them and redirect my frustration to Nissin ha ha
I'm sure I'll find something else along the way :lol:

By the way, when I said "tap" I meant the thread-cutting sort, not the "with a hammer" sort... :roll: You don't seem the type to choose the wrong one but just being clear... :D

Thought that alright, bit of kit I never owned but might purchase next for my collection.
sometimes a torx bit hammered in there will grip where an allen head one wont.. :wink:
Just curious Neil, cos I can't recall of hand, how do you support the pin so you're not beating the s**t out of the caliper while doing this?
Result; I'm an impatient fecker I am...
Cordless did the job (better than I thought Mustang lol), thank god pin is as butter, maybe bit was nice and sharp. Securing it was a bit tricky as I don't have a vice. Drilled straight down through the pin till I could snap it and remove bottom half, that got the old pads out of the way. All I have left now is a "barrel" with a wall thickness of about 1mm that needs to be removed, tidy the threads and order a pin and cap combo, nice one. Think i need a 7mm drill bit to remove most of the remaining "barrel" but I'm so close to the threads now I'll leave that last bit for the experts...
I am delighted to say that the above case is now closed. Drilled out the last bit of the retaining pin, ran the tap through it, used a pin from the front to check and everything is hunky dory. Just need to get a retaining pin and cap.
Delighted as I was I thought I'd fit the female metal fuel connections as well. Bottom plastic one came out without a fight...the top one wasn't for leaving without a struggle. Gently, gently, snap...top came off and threads solid inside the tank, not again. Managed to poke most of the plastic thread out and ran a tap through here as well. Metal fittings are in but were very stiff getting in, especially the top one. Think it's OK though with each a run of PTFE.
Question: some of the bits of plastic thread fell in to the abys, no way I could prevent that from happening. Does this mean I will have bits of plastic circulating in my fuel system? Any thing I could/should do about this?
there is a gauze screen on the pump pickup so no big bits can get in and after the pump is the filter. I would wait until its filter change time and clean the tank out then.
Don't you get a real sense of achievement when you get a result yourself? And it gives you the confidence to push a bit further next time. It's called experience, and owning a Tiger means you get a lot of that :D
Cheers NKL, I'm taking a little confidence out of the fact that the little bits went in to the return line which I hope means they do not end up in the feed and eventually the rack...
@BB, man I could cry yesterday evening when the bloody fuel connection snapped lol, think I have it sussed though. It's encouraging and scary at the same time, but I'll soldier on with the help of you guys and Mr. Haynes...

If everything goes ok, you think, "Cool, this spannering stuff is easy""
If you have setbacks, like the snapped fuel fitting and the seized brake pin, you think, "I'm rubbish, I shouldn't have started this, God hates me" etc etc. Then you stop mithering, take a deep breath, put on the thinking cap, look at the resources you have (and that includes TT.com), get stuck in and eventually you Triumph (pun intended). Then you think "Cool, I am indeed a spannering God"!
Well done mate! :D
Well, have the whole thing back together, fired her up and all, so far so good. There is the tiniest little bubble showing at the top fuel connection if you look really carefully but after the bike ran for 10 mins there wasn't actually any petrol showing, not even a drop. I might just try to sweeten that connector by a mill or two.
I hope that these tiny little plastic bits don't come back to haunt me at some stage...
I've packed the tank with bits of rubber in three places to slightly raise the rhs, that seemed to have worked, all panels matched up and all screws could be put back in to place.
Suppose a coolant change would have been in order as well but that might have to wait till the 24K job. I will change the oil and filter and wait for the retaining pin to arrive (just ordered) for the rear brake. After that I want to put a few miles on her...
For future reference, most Nissin pins will do, I borrowed one from my Balckbird when it happened to me......

Good to know that BB!!
I know its a bit late now but Aldi have selling screw extractors for £5.00 dont know if they would work on cap head bolts? might be worth a look.

They go on sale tomorrow, the 27th, it seems.... :)
:D I keep an eye on the upcoming specials for both LIDL and ALDI as some nice little bits show up from time to time, spotted these as well, might piuck up a wee set just to have...
