General Sticky Brake Question

[stevewfl]

So I replaced my front brake lines and pads as I have every new and used sportbike I've bought (steel braided lines, double H pads).  I've done it quite often.  I did  bike tonight and my calipers are sticking.  Where did I go wrong?

Brakes work great but after a few pulls they don't QUIT working....    what did I fug up?

1) Remove calipers and put the new pads on
2) removed old fluid, removed old lines. Installed new lines
3) extensive bleeding of lines, air removed.



I even thought the EBC pads weren't the right ones, popped them out and put the stockers back in...same thing.

I was thinking caliper rebuild, but they were working great before I messed with them?

Possibly dirt in the master cylinder bleed hole not allowing fluid to return.

Thanks~

Man that sounds like the deal with the fluid not returning.  How do I clean such a thing to see, or is there a simple/ cheat way of going about it hehe

Have you tried it with your Connie fob in the pocket?

Take a toothpick and push it through the two little holes in the bottom of the master cylinder.

Thank you very much, I'll take the banjo bolt out and try and clear them.

Maybe this clog is why the brakes were easier to bleed than any when I've started from scratch with new lines

Are they all sticking or is it just one piston?  And what bike is this on, Steve?

Never mind....ZX-9 eh?

Tell us about the ZX-9, Steve.  We loves a good story, we does.  Does it have two front calipers or just one?  If two, are both seizing?  If one, apply the brakes until it seizes and then open the affected caliper bleeder and if the fluid shoots out (put a rag over the bleeder just in case), then it's an issue with the line on back to the master.  If not, it's caliper related.

By the way, is that the only thing you did (replace lines and bleed) or did you muck about with the calipers and did you change the banjo washers?

hmmm wonder how how i tell one or all, pull the calipers off and see if one hesitates to go back in?

Never mind....ZX-9 eh?  Yes, Connie has linked rubber brakes, 1st bike I ever owned I left the  I left OEM lines and pads

Of course it has two, its not a Hardly-Ableson. If I recall both calipers are hard to pull of after a very short ride, but i may need to confirm if one is really harder than the other.....   good question for me

By the way, is that the only thing you did (replace lines and bleed) or did you muck about with the calipers and did you change the banjo washers? Changed lines, banjo bolts and crush washers (all Spiegler)

Jim, Thanks for this help!  I haven't ever had issues with pads/lines swap, this will be a learning experience indeed.

Front/rear Brake calipoers on the ZX9 rebuilt, brakes work GREAT 

C14 is next, its 30,000 miles overdue for it according to the book, so I wanna' be "proactive hehe
