Caliper Pin

Anyone know where I can get some caliper brake pad pins quick? I stripped both on the front right caliper, was on way too tight. This is stopping me from changing my brake pads and tire which I need to get done right away for an up coming trip next weekend. I have a 2007 ZX6R with nissin caliper. Are these pins somewhat universal meaning can I use pins from other bikes or caliper?

Thanks in advance.
 
try left hand drill bits and easyouts, i guess you started with an impact driver first?
 
Ok I really F-ed up on the caliper now, I was able to get one of the pins out and the other one was so tight that I couldn't break it loose, even with the extractors at various sizes. There's basically nothing left on the "pin head" for anything to bite into anymore. I did try drilling it out but I might have made it worst. So what's my next option?????? Replace the whole caliper? Also since the pin is somewhat permanently in there, will this affect braking when riding at all??

All help is appreciated.
 
I might try the following if you think its a write off.
Take it off
Strip all the rubber out of the caliper (remove the pistons and seals)
Then gently warm the area around the pin . The aluminum will expand faster then the pin and it might help loosen it.l

Also if you get the caliper on the bench you may be able to drill it out on a drill press.

Can u get inside the caliper to cut the pin with a zip disc, then you can work at one end at
time ?

If you in a rush , gret a used one and fix the old one in yr spare time .
Do have pics ?

Nothing wrong with riding it like that, the only reason the pin needs to come out is to change the pads. A friend of mine has the same problem in Jamaica, and because they dont really have money to fix little things like that he just leaves it. And when he has to change his pads, he splits the whole caliper and has to re bleed it every time, because the pin is stuck...

I have had luck in the past, splitting the caliper and using vise grips or a bench vise to turn the other end of the pin that is inside the caliper. If that doesnt work my last resort would be a machine shop, $20-40 and you can have it milled out and the treads cleaned up...If you have a friend or a friend of a friend you can probably even get it done for free or a coffee or something
 
I'm having this exact problem right now - was't too worried because of the weather, but now I want it fixed!

I tried removing the caliper and using vise grips to turn it from the the stem of the pin, but have just chewed the metal to the point that I'm afraid to put it back on to ride to the shop.

I'm thinking that an easy-out will just break if the vise grips can't even move it.

Looks like I'll have to remove it from the hydraulics and take it to the shop.

Grr!
 
Midwest Caliper on Midwest off Midland Ave.

Great bunch of guys and have pins, seals, boots, etc in stock for most bikes. Good prices as well
 
Here is a pictures. I'm pretty sure the caliper is done, at least it looks that way to me, I think I've drilled into the actual caliper. I did take it out for a long ride and everything seems to be fine, no different than before.

Yeah, you might have caught just a bit of the caliper there with the drill LOL!

As far as I can figure out, and someone will correct me if I'm wrong, you only need one pin. The second one really just serves as a back-up. Having said that, now you have no back-up pin so if the other one falls out you will have zero front brakes with no warning. This is what that looks like;

Of course the only correct fix is to replace he caliper.

By the way, you didn't strip the bolt you rounded the head.

OMG I need a new caliper ASAP! These calipers are actually 4 individual pads so 2 little ones on each side of the caliper rather than a long pad on each side.

Wrong! Because his calipers are pad per piston...Meaning there is 4 seperate pads, 1 pin hold 2 each....Without that bottom pin there is nothing to hold to 2 bottom pads in the caliper
 
So I broke an easy-out, and then snapped the pin end off with vise grips.
Obviously, I'm going to have to take it in to a machine shop.

Can any automotive shop remove a pin (bolt, etc), without killing the thread?
Should I be looking for a specialized machine shop?
Anyone have any recommendations in the Burlington area?
 
2 bad your so far away i would fix it. Im in Concord area. I would cut the pin and split the caliper heat the pin to crack it free of any lock tight or oxidization (if the last person used it, dumb ***) let it cool again and grab hold of the pin once the pads were removed turning it in. make sure that u leave room to grab hold with a wrench or vise grips. You can grind a flat on it to try and use a wrench as well. If all else fails drill it out with the apropreate tap drill and retap the hole.
 
Buy a set of Torx bits from Princess Auto ($5). http://www.princessauto.com/workshop/hand-tools/driving-tools/torx/8001049-11-pc-torx-bit-set

Find the largest Torx bit that fits inside the stripped Allen head. Take the next size up and hammer it into the bolt head like so:

Hammer straight down making sure to keep the bit inline with the bolt. When you think you've gone far enough, give it 10 more hard smacks. Then, when you can lift the calliper assembly holding only the bolt and shake it and it doesn't come loose, give it another 5 smacks with the hammer and THEN drive it out with your ratchet/t-handle/flexhead/breakerbar.

Not my idea. Read it somewhere and it worked. :D
