You can die. Do Not Drive the car until the brake system is flushed thoroughly and refilled with the correct brake fluid!

if the clutch works it should be okay but I would not do it because brake/clutch fluid is designed with specific properties for this purpose. If you hydraulic fluid is already in the reservoir only and not throughout the system then you could suck out the reservoir with a turkey baster and replace with correct fluid. The CORRECT solution if hydraulic fluid has been introduced to the system id to bleed the entire system from the clutch slave cylinder back to the master cylinder.

I put 5 quarts of 10w40 motor oil in my ttr 225 and it was smoking really bad. The motor started clicing after awhile and then shut off and won't even turn over. Could anyone tell me whata wrong

Could have left the drain plug out. Seen experienced mechanics do that. Or maybe didn't tighten it and it fell out. Forgot the oil filter? Put the oil in the wrong spot? Sorry for the questions, but some people just don't know. Not that they are less than bright. I've seen oil in the coolant reservoir, coolant in the wiper reservoir, engine oil in the power steering and brake reservoir. Engine is probably dead though.

I want to know what the black cap by the oil dipstick is on a 2010 Pontiac G6?

On a 2002 mustang it is the reservoir for brake fluid. The fluid level should not be high enough to leak. One way to get too much is if someone adds fluid to the reservoir because the level is low. Its normal for the level to go down as the brake pads wear. The piston pushing on the brake pad requires more fluid to force the brake pad into the brake rotor as the pad wears. If you put more fluid in and later replace your brake pads, the pistons must be pushed back to their original position to install the new pads. Pushing back on the pistons causes a backflow of fluid to the reservoir. Since you added more fluid earlier there is now too much and it can overflow. If this is your problem you can bleed out excess fluid. The valve to bleed the fluid is down behind the wheel near the brake pad calipers.

Motor oil in power steering reservoir?? How or what causes this to occur? PLEASE HELP!

I can not see how engine oil can get into the power steering system. Even if the pump is gear driven from the cam or crank and leak would allow steering oil into the sump and not the other way around. I think that he oil you are seeing is the power steering oil badly burnt from a failed pump. It is possible for some one to put engine oil in or an additive that was incompatible with the steering oil .Pull a hose and drain the fluid out of the reservoir. Do this 2 or3 times . I imagine there will be pump damage already so if you are prepared to drive to the garage for repairs do it in anticipation of complete steering failure and keep the speed down Personally I would put it on a tilt tray and have it delivered to the garage. It may be cheaper in the long run

AmberjugsCan I put brake oil in my VW Golf or does a specialists have to do this?

You can easily put in brake fluid yourself. Just make sure you use DOT4 brake fluid (Castrol, etc..) To top up your fluid locate master cylinder (drivers side, white plastic reservoir just in front of driver) remove cap and top up to "full" level (marked on side of reservoir)
