Title: caliper issue
Post by: weaselnoze on July 29, 2005, 04:00:27 PM
ok so why is point A hitting the rotor before the actual brake pad?!  it can slip past the pad.  these are brand new pads with 0 miles. the pad's inner edge is lined in green.

Hey, how about posting this at the end of your other thread on the topic (http://gstwins.com/forum/viewtopic.php?t=19448)?  :roll:

Too much flashlight talk, I guess.  Sorry about that.

It looks like a squeal tab, to me. I know they used to have them in the 80's on cars. Is it part of the pad or the shim behind the pad? I never reinstalled them on my cars. 8)

its part of the whole bracket that moves back and forth.  it keeps the pad in place but gets to the rotor before the pad does.  the design makes no sense to me.

well i should have said before that the reason i put new pads on was because i thought that was my problem.

Any feedback on the pictures I took (http://gstwins.com/forum/viewtopic.php?p=177750#177750) for your other thread?

Are we talking about the same thing?  The lines you drew above kinda obscure the item you're trying to show us. :dunno:

ok kerry.  your first picture shows the metal clip ie pad guide.  when mine hit the rotor it got all bent up and when i tried bending it back it broke.  but really i dont see its purpose at all.  it still allows the bracket thing to slip past the pad and contact the rotor first however this time its the metal clip that touches and scores my rotor.  
so now i dont have a rotor.  btw i noticed that the bracket reaches the rotor first in two places as marked in the new picture below.

its a 2000. there is nothing visibly wrong.  thats what stumps me..
Title: caliper issue
Post by: weaselnoze on July 30, 2005, 10:09:07 PM
just thought of something.. are there supposed to be rubber things inside the pistons? i remember there were on my friends kawi but these are empty... didnt see them on the fiche but its just a thought..

gotta bump this. i know u guys are getting sick of this thread but seriously  someone has got to have an answer...
Title: caliper issue
Post by: scratch on August 01, 2005, 03:30:10 PM
YES! That's it! There are supposed to be a couple of plastic (mine are hard plastic) inserts, one in each piston!
Title: caliper issue
Post by: weaselnoze on August 01, 2005, 04:00:32 PM
are they flush with the rim of the piston?? how come i dont see them in the parts fiches?
Title: caliper issue
Post by: coll0412 on August 01, 2005, 05:29:55 PM
Yeah mine dont have the inserts...and they shouldn't matter since the piston would jujst have to go out a little farther
(http://www.tc.umn.edu/~coll0412/bike/weez/1.jpg)



What is interesting is that if I push the mounting bracket out farther I have the same problem as you...(sorry for the fuzzy pic my roomate helped)

(http://www.tc.umn.edu/~coll0412/bike/weez/2.jpg)

Here is what my caliper looks like when it first came off....
(http://www.tc.umn.edu/~coll0412/bike/weez/3.jpg)

You can see that the slide can move back and forth, the metal clip and the end has no effect.
(http://www.tc.umn.edu/~coll0412/bike/weez/4.jpg)


Do you have the metal clip thing on top of the caliper( or in the pics under the pads)??

So check the slides and make sure that the mounting bracket can go as far back as possible and make sure that the it can move freely.

Also compare your old pads to the new ones....

I'll keep thinking about this....

Cool//

thank you for the pics coll.  no i dont have the small metal clip. i removed it after i determined it had no effect to my problem.  i have the same problem with the old and the new pads.  the slide moves freely as you describe.  everything you posted is exactly the way mine is.  WTF!
Title: caliper issue
Post by: coll0412 on August 01, 2005, 06:55:34 PM
actually I was wondering if you have the other large clip that goes on the top of the caliper( it is hidding in my pics cuz its covered in brake dust)


Can you move the mouting bracket all the way in, and give it a shot again.
I think if you push the bracket all the way in, then mount the caliper and give the brake lever a good squeeze it should work, cuz it did for me.

I wonder if maybe you should splurge the $.99 for the clip... 8)

Post by: weaselnoze on August 01, 2005, 07:56:35 PM
yes i have the larger clip. i was refering to the smaller one.  #7 in the fiche and is name pad guide or something... i'll give it another shot tomorrow! thanks for taking the time to help me out

Well the only other thing that comes to mind is that if the clreance holes on the fork tube got twisted towards the rotor.

The only conclusion I can come up with is the the distince from the mouting bracket to the rotor is too close, and the only thing that controls that is mount on the fork.

Quote from: coll0412Yeah mine dont have the inserts...and they shouldn't matter since the piston would just have to go out a little farther

I went and looked and you're right. I can't even see them. Plus you would want the piston to act directly on the pad for better brake response and feedback anyway.
Title: caliper issue
Post by: weaselnoze on August 02, 2005, 01:41:12 PM
so i shouldnt worry about the inserts then?
Title: caliper issue
Post by: coll0412 on August 02, 2005, 03:53:16 PM
No, you should still get the inserts.

What side did you crash your bike on? What I am thinking is that is twisted your caliper and is basically pushing it into your roter

the main blow was to the tank/frame on the left side.  the wheel was bent up too.  forks appear to be fine but maybe are skewed some.  i'm gonna tackle it again in a few minutes.  i wonder where the inserts went?!  first time i had the front caliper apart and they arent there? weird.
Title: caliper issue
Post by: weaselnoze on August 02, 2005, 04:40:00 PM
ok just thought of something and 2000's dont have the inserts.  95's do.  so it changed with the caliper i guess

Post by: Eklipse on August 02, 2005, 05:03:13 PM
You know what? Mine did the same thing after I had a little accident with my disc lock. It ground the metal tab off, it was sparking and stuff. I straightened that $@!& out, and filed the tab down.

Problem fixed.

sounds like it would work but idk if its really safe.  how much did u file down?
