I noticed my front caliper is leaking brake fluid on my 06 k9. I ordered a rebuild kit for it but couldn't find a post on how to rebuild it. Was just wondering if there's anything speacial I should know before I tear into it. I know bigdogtech stated not too long ago that he's done a few. Any advise would be appreciated. Thnks

Hey Travis, waiting on parts for mine.... took it apart and it seems real simple to rebuild..just take out the o-rings and seals, clean and replace the tension spring....just need to make sure you get the right kit.....mine had a large and small piston so make sure before you order..o yea make sure you use the right brake fluid..

May want to do some checking. I know there was an issue with brake calipers in 06. I know a few guys including myself that had the same problem (leaking) and ended up with new calipers from BDM.

I had to do the front & back calipers on mine, fairly easy to do, the hardest job was to get all the pistons out, I used a air compressor to pop them out. Hardest thing is to cover all the holes so the air does not escape. I had to get the full kit with new piston because my bike had been standing for years:up:
 
You might want to try to determine exactly where it's leaking from, first.

I've seen the banjo fitting leak. You snug them up just a bit and the leak stops.

I've seen the caliper fitting start leaking. You can try snugging it as well or just re-Teflon tape the fitting and reinstall and bleed.

and here's a strange one, chopper brakes "sometimes" are hard to bleed and completely remove all of the air out of the system due to their long brake lines.

"IF" the brakes are bled "improperly", and air remains within the system. I've seen them leak around the piston seals & boots in spot about the size of a quarter, during the overnight period.
If this is the case re-bleed, taking the following necessary measures that will allow the fluid & "air" to escape, but "NOT" allowing any air to re-enter the system during the return stroke of the bleeding process. This is easy to accomplish by attaching one end of piece of rubber tubing to the bleeder valve nipple. Place the other end of the rubber tube into the bottom of the can, in the fluid itself, of brake fluid "after" you've filled the brake reservoir. Then bleed system like normal, and slowly taking your time, until no more air bubbles are returning into the brake fluid reservoir. :2thumbs: Then button everything up, clean thoroughly and continue to watch for any signs of a leak.

Just a little info, hope it helps. :2thumbs:

dead :cheers:

another bleeding method i use is simple,take the bleeding hose connect it to the caliper bleeder,the other end to a oil squirt can,squeeze slowly,i have used this on bikes i had trouble bleeding,it pushes oil back up to master instead,someone else on here had bleed issues,reccomended this and trouble over,just another method,what ever works for you,mobsta:cheers:

This was an issue with 06 Dogs. My front brakes were replaced under warranty but the issue was well known by BDM. BDM may help you with exactly what the necessary fix will be.

Thanks guys, I'll see where the leak is exactly. I doubt BD will warranty an 06 now and the rebuild kit is only $13 anyway. Thanks for the bleeding tips too.
