To Bleed Or Not To Bleed?

Hi guys just a quick question as I've done a search.
Do I need to bleed the front passenger side brake?
This was my first time having a go at changing the rotors and pads and I undid the bolts that held the caliper in place (starting from bottom to top). I realised that when I undid the last top one slightly some fluid came out so I redid it. Now I'm wondering do I need to bleed just that side? Thanks, I'm new to brakes so be gentle.

There shouldn't be any fluid coming out when you're removing caliper bolts. You had best show us a photo of what you mean.....because if you were splitting the caliper accidentally, you might be in some trouble.

And here's a pro tip. ALWAYS bleed brakes. Every opportunity.

Yes the caliper split slightly, but I still had the top one done up. It was only till I loosened it slightly that fluid came out. It's all together and well, I just need to know if I need to bleed that brake specifically.
I will bleed them all when I get the chance, but would I be able to drive it as it sits now?

Off the record, your not supposed to split the calipers, the bolts are torque to yield items and should be replaced, as should the oring that seals the 2 halves.

Having said that, i know heaps of people who have split them and reused the old bolts.....but with a new oring.

Yep, you have to bleed now, no ifs or buts about it.....dont even think about driving it, you don't know how much air got in.

I know I wasn't supposed to split it, but I didn't know those bolts held the caliper together.
So now I've got to get the caliper pulled apart to replace the o ring?
OK bleeding it isn't such a problem now considering I don't know the problems I have made, by slightly loosening the caliper.

Edit: I'd also like to add that it is not leaking at all since I did up those bolts.

So you tested it while hot under full pressure braking with the master full of vacuum while the caliper flexes under high speed load?

You 100% sure it wont leak? :)

Hence why the oring should always be replaced......

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?

      You can probably scrub the rust with a toothbrush or something. After you get the rust off flush well with water to neutralize and you will probably want to also use a fuel tank sealer to keep it from rusting again.

      The sodium citrate solution is designed to buffer the citric acid to keep it from attacking metal quite so much, the guy that came up with that recipe did a ton of testing on how much metal loss occurs over time and it's nothing crazy unless you forget about it for months:
