How to clean breaks on Casitas?

[Skeeloco]

My Shimano began to lose distance and seems to be making a bit of a whirring sound when casting. I pulled it apart, cleaned, oiled up, and even replaced spool bearing with a ceramic bearing. Still the same, no difference. I imagine it's related to the brakes but don't know how I can clean and oil them up. Don't know what kind of brake system they use but it's sure not centrifugal.

That sure looks like centrifugal brakes to me.  The way I clean them is take a clean dry Qtip and wipe the drum.  Then put a little Shimane oil on a Qtip and wipe the drum.  How many of the brakes do you have set to engage the drum?  You may want to experiment with that.

Is it possible that the brake dial and the brake ring gear have become disconnected?  Here is the schematic.  https://dassets.shimano.com/content/dam/global/cg1SHIFSEH/EV/15CAS150HG.pdf

If by drum you're referring to a metal ring around the side plate, there is none. Pure plastic. I have 2 brakes on, 2 off.

Nope, taking off side plate they're both engaging eachother fine.

Use some alcohol on the metal then light coat of oil. I would get rid of that orange seal hybrid bearing, or at least flush an re lube it.

If you have those orange seal bearings on the spool get rid of that one too. Shimano stock bearings are some of the best ones available, check your schematic and replace with original bearings.

The inside one around the bearing is the centrifugal race.  The white tabs are the centrifugal brakes and bottom of them is pushed onto the "brake pipe" centrifugal race in the center as they fly out on the cast.  The top part of the brakes swing out and this makes the bottom part contact the race since they are hindged in the middle.  How many brakes are on or allowed to swing?  Two on and two off with zero spool tension is about right for those reels.  You also have am external dial that moved the tapered brake pipe or drum in and out.  In = higher number ans larger diameter centrifugal race for more braking.  Out = smaller number and a smaller diameter centrifugal race.  When I had one I used braid and ran two brakes on, zero spool tension and around 5 on the brakes. Below 3 would blow up on me.

Did you change "spool bearing" or "spool bearings?" Singular or plural? Because the other spool bearing could be damaged as well.  

 

Also, make sure the spool shaft is clean without any oil or grease on it. Clean the spool rim and the reel frame, so there's no dirt or debris between them two.

 

Then, I'd clean the brake drum with alcohol, and change the brake shoes (turn off the two you used before, and turn on the other unused two).

Shimano uses some of the best stock bearings. I highly doubt they were bad and ceramics are louder by nature. As for the brakes alcohol on a swab followed by a swab of light oil is all you need. Those are indeed centrifugal brakes.  They swing out to make contact with the cone as opposed to sliding out to contact a ring. The notion that a reel should or will be totally silent, especially after some use isn’t realistic in most cases.
