Sudden fluid leak from brakes??

Sudden fluid leak from brakes??
Ok, i decided to change my front brake pads on my 2015 dyna wide glide. I replaced the rear about a month ago. Everything was going as planned and looking normal until i unbolted the front brake caliper. As soon as i removed the caliper from the front rotor, brake fluid started running out of the caliper all over my floor. I removed the front caliper master cylinder cap and as soon as i did that, it really started pouring out the front caliper.
Did i do something wrong unbolting the caliper? I did this just as the manual explains it. The banjo fitting did not come loose. I just finished riding all day yesterday with no issues. Pads are first time replacement, 22,000 miles on bike.
Any help would be appreciated.

When I do the first and second replacement, I take some fluid out of master. I pull caliper and remove pads. I put a shim of plywood in and push pistons out a little farther then they have been (but not too far!) and shoe polish them clean before pushing them back. The third set of pads need a total rebuild of everything. Depending on time, maybe even the second.

Can the pistons in the caliper get pushed out too far? Because i left the master cylinder cap ON when i pulled the caliper off.
Also since this is a 4 piston caliper, if pads were very thin, pushing caliper over pushed fluid out behind them. Since master was capped and fluid was not dipped out, it pushed on the other side piston and pushed them out.
Caliper needs rebuilt or replaced and properly bleed. Do not attempt to do this out of a service manual without doing a lot of other home work or with someone experienced .
You are truly asking questions or not telling what is going on . Sounds to me like you lack the mechanical experience to safely do what you are trying to do. Not trying to be a jerk here and we all need to learn. I started at 16 with a year of shop in automechanics.

Ripsaw, i agree with you completely. I have done many disk brake jobs over the years on cars. So, i know the concept on how the system works. But not exactly on a motorcycle. Like i said in the beginning. I did the back brake with no issues at all.
As soon as i took the front caliper off the rotor (without first taking the cap off the master cylinder) all hell broke loose before i could do anything. Brake fluid went everywhere. I just got back from autozone with some brake kleen. Im going to go spray it down and try and find out where the leak is coming from. Ill be back soon with my findings.
