View Full Version : A noobie at my age!
Just like to start by saying thanks to all, I've been reading a lot of different posts for advice and tips. Unfortunately my bike failed its MOT due to a fork oil seal, too loud exhaust ( says its legal on the paperwork as long as the baffle is installed but what do I know? ) , rear bearings and something about the front brake not springing back ?? Anyway the thing I am now having such a problem with is the front brake pads, I decided to change them cos they looked very very low to me but they got through the MOT ( years ago I used to be a t**t and crashed very badly and totally shattered my skull and actually died briefly so I figure I'm here for a reason but this has left me a wee bitty nervous about being back on the road ) sorry I'm prattling on but the pin thing on the front brake is driving me beserk. I've removed the clip and tried wd40 and heat but never done this before so I'm not sure about what exactly to heat. Is there anything else to try or just percevere as I am? Thanks for reading this and any responses.

Grind the nipple off the caliper and knock it through that way.
Your MOT man seems like a c##t.

Aye, if it's a free retest sort stuff and take it back (bike it do universal baffles for like a tenner). If they're going to charge you take it to a better tester, but sort the brakes and wheel bearing.
Oh and shattered skull...wtf! :smt104 Sounds horrific.

Been a while since i heard of anyone failing on the exhaust noise....
Welcome to the org btw :smt039

+1 on that score.
welcome in, once your here, you never leave:-D
Hi all and thanks for the welcome. I've managed to put the original exhaust back on and renew the fork seals and rear bearing but I am now left with the seized on pins, just considering putting it back together as is because she didn't fail on the brakes but my girlfriend wants to go for a bit of a road trip during the summer and I wouldn't be happy knowing how low the pads were, just a bit fed up trying to get them off and failing miserably. :(

Easiest way is to grind the little nipple off. Put a blob of black silicon over it when you're done and you can't tell. It makes no difference to the integrity of the caliper either.
Again thanks for the reply, err just to clarify as I'm a wee bitty daft and usually end up hitting things with a hammer, grind the nipple off - I take it you mean the bumpy out bit in the other end of the bit that your supposed to grip and pull the pin out with? then knock out the pin and cover it over with silicone? If I've got it wrong, humble apologies as the last bike I worked on was a yamaha rd oh sooooooooooo many moons ago.

Yes, the aim is to be able to get to the enclosed end of the pin with a punch to knock it out.
You don't need the silicone at all unless you want to hide the fact that it's drilled. Coppaslip does the trick better.
Don't grind the nipple off because the pin can slide through that way, drill a 3mm hole in that bump central to the pin and tap the pin out from the bump side in the direction it ought to come out, after soaking in penetrating fluid. A 3mm hole gives enough of a shoulder to stop the pin coming out of the caliper the wrong way, but it's big enough to get a parellel pin punch in.
Aahhh that sounds good, mind you - with me - I'll probly be looking for front calipers soon, he he he :rolleyes:
Wow, you guys know your stuff! A small hole, a sharp punch and bingo! out it comes - WAYHAY!, now where did I put that Rclip? :)

I'd seriously advise against drilling out the brake cliper, I had exactly the same problem and after screwing around with hot/cold penetrating stuff overnight soaking etc etc i just cut through the pin and wiggled out each half with pair of pliers, 5 minute job..
I think that people should stop recommending drilling out the caliper unless it's a last resort. I was all ready to do it until I just used a cheap hacksaw to cut through the pin. Even if you have to do it next time you replace the pin it's still better than potentially weakening the caliper or making a mess of the drilling plus it can be done quickly and easily without draining the brake fluid.

I used penetrating oil, heat, a punch, a hammer and some molegrips.

I use stainless pins and copper slip. I too believe drilling out the back as a last resort and agree with Lozzo. Grinding the whole of the back off is complete over kill and unnecessary.

Aye now I've found my copper grease I'm going back greaseing everything!

The stainless pins are the key.

The stainless pins are the key.
Are they just normal split pins? or are they awkward caliper pins so you have to buy them from suzuki. I might have some long stainless split pins actually.

As far as I can figure it makes no difference at all to the integrity of the brake caliper, and is free. Compared to buying a new pin after chopping it in half or otherwise ragging it to bits with mole grips.
+1 about the stainless pins though.
They aren't split pins, they are a straight pin with a cross drilled hole for an R clip.

welcome the org sookie....im guessing you not been using this mot guy long? failing on the exhaust seems a bit harsh as its down to his/her? descretion......my bike mot'd not too long ago, knew the exhaust was loud, tester bloke just put it down as an advisory.....anywhoo...welcome welcome

No it can't, the other (inside) side of the pin has a shoulder on it bigger than the inside hole. The pin is constrained from sliding outward by this shoulder, and from sliding inwards (normal route of removal) by the R clip.
I can see why a 3mm hole would look neater though, provided you centre pop the middle of the nipple.
I seem to have semi comprimised because one side went well with a small hole and a sharp punch doing the job but the other side was more difficult and ended up being, rather stupidly, re drilled ending up with thumb fingered me taking the majority of the nipple off but hey ho its done now. The fun I'm now having is putiing her all back together. The light works, I attach the front fairing and "oh no they don't". EXCELLENT.
The exhaust is/was a Motad Venom? and the paperwork clearly says it conforms to EC noise standards and the MOT peeps said something about it being louder that a standerd bike, I thought it was a bit of a contradiction on someones part but not wanting to argue with the ref I just accepted this. Was I being dumb?

Yes the motad system is a little louder but still perfectly legal as far as I know. MOT man sounds like a c##t.

You heard my exhaust chris, mot man passed it at that and said sound bang on.
That's a proper tester.

Welcome to teh .org, fella.
Yeah sounds like the MOT guy was maybe a bit of a flump but I'm a wee bitty surprised because of the place I took it...Quite well known and established, well, in Edinburgh where I am anyway. Mind you its probly something else I am unaware of, jeez. A noobie! me! I'm too old for this, learning new stuff n that, lol.
