i own a 01 maxima. when i did the oil change i poured 5qt of mobile 1 instead of 4 and half quart which was factory recommendation. in the morning i checked the dip-stick and the oil level was not in the middle of hot and cold sign it was little over the hot level. is this anything to worry about?
ok now regarding the brakes whenever i drive downhill in the mountains the front brakes on my car start making squeeking sound while pressing and releasing the brake pedal i could hear it while driving. but it doesnt make that sound on flat roads or freeways only in mountains...why is that? do i need new rotors becuz i just had the new akebono pads installed like 17,000k ago and had the rotors turned on machine, but. this time i am looking to get HAWK pads i heard some good reviews on them. so should i buy a new rotors or just get them machined once again..? and what type of rotors are better those slotted onces etc? please help. thanks!

The Extra 1/2 quart will NOT hurt anything. Don't worry about it.
On The brakes, It sounds as if perhaps the anti squeel compound was not placed on the back of the pads during installation which will let the pads squeel, especially when they start to get hot such as being used a lot on a mountain road. Have the Rotors checked. If they still have enough material, have them turned. If Not, replace them.

I wouldn't worry too much about the oil as long as its not too far over the fill line. If you really wanted to you could let a little out through the drain plug, but it probably wouldn't be worth it. You would have to guess when a half-quart had come out. Then again if is really high over the full line it can cause soime problems over a long period of time. The oil pressure will be higher which can wear out gaskets and seals quicker.
The brakes pads are probably worn out, especially if you do a lot of mountain driving. Most pads have a layer which squeaks when they get low so you know when they're wearing out. Then again some pads just squeak no matter what. Using your brakes down an incline all the time eats them up really fast. They get very hot after all that braking and thats probably why they only squeak going down hills. Try putting the transmission in a lower gear and let the engine do some braking. That will make your pads last longer. I wouldn't worry about getting slotted or cross drilled rotors, thats just overkill on a normal car. Just use engine braking on the hills and have the pads checked ever once in awhile for excessive wear.

Are you sure you check the oil? The hydraulic oil dipstick has a hot and cold level marker on it. Most car's oil dip sticks do not have the words hot or cold on it. The oil dip stick has a low and high mark on them. I don't have a car like yours, but something pop out when you said hot and cold. Oil doesn't change level based on temperature. The hydraulic oil does, due to it being used in the transmission.
Too much oil is not good for the engine, but I don't think 1/2 qt is going to damage anything. The next time you change the oil and oil filter, put only 4 qt in... turn on the car...check for oil leaks, shut the car off, check oil level. Add only what you need to hit full. When you change the oil filter, it will be empty of oil. When you turn the car on, it will pump oil in the filter. Always check after you run the car once for a minute, then add oil.
You can keep turning the rotors until a minimum thickness is hit. If the brake pad are glazed over from heavy use, they will make a noise.

First those marks are not hot and cold. Those marks are full and low. A pint over shouldn't hurt. The squeeking is likely just heat. You are braking more agressively. They will only turn rotors to a safe level, so don't worry about that. When the rotor thickness is worn too much, they will refuse to tun them. That is generally 25% of original thickness, or less. Likely closer to 15%

it probably won't hurt anything overfilling by 1/2 qt,but don't make a habit of it.when driving in the mountains there is usually a wall beside you that reflects sound that isn't there in flatland or freeways.normally you only get one turning on a set of rotors before they get too thin.studies i've read show that you have to be a racecar driver to tell any differance between rotors,so buy what you are comfy with.

ok first thing,it wont hurt to have the oil a little full(if its not too full)and about your brakes,it could be just dust,or your pads are worn down to the squeeler,i doubt it if you need rotors,but you better get checking on the pads.if they look good just spray them with brake clean(you can get the spray at auto zone)check to see if you got bonded or riveted pads.
