If you have a stick it's your master and slave cylinder, if not, then you have a brake fluid reservoir and a power steering reservoir

Stick would have PS also, so it'd have 3, just so I'm clear on that, but if you only have 2, chances are you're lookin at the PS res. Since we're on that topic, doing a Power Steering fluid change is a great thing to do if you have some miles on your car, my shit was burnt and nasty

its a 2.2 5 spd.. and there is 2 brake fluid resevoirs, steering fluid resevoir is not shown in pic.. so do these 2 resevoirs take different fluids? i dont feel safe pouring watery liquid fluid with thick fluid, it doesnt seem right.. i need to fill the bigger reservoir with i geuss brake fluid but what kind is thick??

also what the heck is this? its from underneith the rear hubs/rotors or whatever it is

Dont you have the owner's manual?

As far as i know, one is the clutch fluid (the smaller one) and the other one the brake fluid. Both use Dot3 brake liquid

My best friend who's a mechanic did it, he used a machine that sucks old fluid out, and exchanges it with new fluid, I know NTB, sears, and grease monkey all do this service, you can't just drain and fill unfortunately, plus you have to work the rack back and forth while the fluid is being cycled, requiring 2 people

I did the steerring fluid exchange by myself, if you look athe resivour for the steering fluid it has 2 hose connected to it. One at the top and one at the bottom. with the car off suck all the fluid out of the resivour then unhook the bottom hose and connect it to a plastic bottle or some thing now pour in fresh fluid and start the car and start turning the steering left to right and keep pouring more fluid into the resivour when you see that the color of the fluid has changed to the color of the new oil stop and top off the resivour making sure that you have worked the steering a couple of times such that there is fluid up to the max mark in the resivour....

I did the above and it worked for me juts check the level after a couple of days...

my 2%

The bigger cap is your brake Fluid, the smaller one is your clutch master cylinder, the slave is on the transmission. Both use DOT 3 or DOT 4.
