What is this part ????
What is this reservoir??
There are 2 pipes with some sort of connectors on both side near rear tire and shocks,,, but those are not connetced to any thing on my ride.
So please help me with this issue and let me know what is the purpose of this part.

It looks similar to an LSPV (load sensing proportioning valve) which increased the braking affect of the rear wheels when you were loaded down with weight to prevent jack-knifing. Your picture is too close to rule out if a previous owner or mechanic was bypassing it.

I think the previous owner had it disconnected or changed the part which required this system,, but i dont know what it is and where dose it go in terms of fitting..
i have taken some more detailed pictures of this part and its pipe systems, so you guys can help me in order to know what does this system do.
These are the (connector or plug ) I don’t know what to call them ,,, on left and right side near the rear spring.

It looks original based on the plastic retainers and brackets that are holding everything in place. But along the rear of your axle, the brake line and ABS wire also look stock. Is this a California CARB truck? I'm just guessing here at this point, could it be some vapor recovery something or other from the fuel tank? From your one picture, one of the lines coming out goes to a dead end open banjo fitting. Banjo fittings are usually used for fuel line or brake lines (although not OE Toyota brake lines). Where does the other hose go? I can see it connected to the cylinder canister, but where is the otherside?

Certainly 'looks' original/OEM. What year is your 4Runner? Also - what's that shield/cover around the spare tire? That's also something I've never seen underneath a 4Runner.

My car is a 2001 Toyota Surf SSR G 2.7lt (RZN-185), the system looks like a original part from factory because there are proper holding brackets and there are two lines coming out from it.
One from the down is going to left hand side and the other is going to right hand side with proper pipe(sort of metal), both of them are then connected with a sort of connectors from which these soft rubber pice with banjo fittings are hanging near the rear springs....
I am thinking could it be related to rear shocks or suspension,,,, because its too far from brake lines.

This is the flexible pipe which is from the passenger side.
This pipe which is in the black casing is going towards the drivers side.
This is the flexible pipe which is on the drive side.
Hope this will help you guys in pin pointing this part,,,

It doesn't appear to have any lever or other connection to the suspension, so I don't think it's a load compensator for the brakes.
I've owned some 70's Volvo's before that had a 'pressure spike' reducer on the rear brakes that looked something like this. No connections to anything other than the brake line coming in from the master cylinder, and coming out to the rear calipers.
It momentarily reduced pressure to the rear brakes. mostly in a complete panic - if you SLAMMED on the brakes, it would delay the rears by a split second or so, so they didn't lock up and skid.
But I wouldn't think that would be necessary on a vehicle equipped with ABS, which it appears yours is.
Is there only one of these things, or are they on both sides?

Hmmm, might be something to do with the original shocks?
Something called 'X-REAS'?

Only thing is I can't really find any mention of XREAS being on 3rd gen 4Runners. But an Australian market thing maybe?
The frame mounted absorber/cross-link thing is in a different spot on a 4th gen, but the unit itself sure looks like what's on yours:
Most mentions of this system are where people are removing the stuff, or at least just replacing the XREAS shocks of 'normal' shocks.
