Brake fluid leak

[vista461]

Well just when I think its smooth sailing I noticed a few drips under the left side of the front tire. Appears to be brake fluid. Brake lever doesn't feel bad, hope its just a copper washer, will dive more into it tomorrow. Also if it is , I hope its a common enough part that the local dealer has them in stock

Most likely the piston is leaking in the caliper.

Booo!!!
That would be my luck
Is that usually just the seal, assuming the bore and piston are not pitted

It doesn't matter if the bore has corrosion as long as it's not pitted in the seal groove, but the pistons can't have any pitting in the seal sweep area or the caliper will leak.

Whats the easiest/least messy way to get the piston out of the caliper? I want to pop it out tomorrow morning so I can figure out if I just need the seals or the piston too.

Thanks

Air pressure works well. Keep fingers away from piston when it comes shooting out. Wrap your air chuck with duct tape so it will seal in the banjo hole opening.

Thanks! Hopefully get that done right away and ride the wife bike to the dealer. It like a sickness I love riding everywhere, even I can't do it on mine.LOL

Came out easy with the duct tape method
there are some pits about 1/4" from the grove in the piston. So I guess I'll be ordering the piston and seal kit at the dealer. Hopefully this will be the last thing I have to order this year. lol

Just out of curiousity, it there a way to clean the brake fluid out of the pad or are they shot?
