Do i need to change my brake fluid or pads?

It's gotten to the point with my car now that pressing the brake down about 40% does absolutely nothing, and I need to press the brake down about 80% to stay at a stop. The wheels don't squeek, but my friends tell me that it sounds like the brake pads. But I know if my brake pads were really that bad they would've been squeeking by now. What do you think?

Too much brake peddle travel generally indicates worn brake pads, or else lack of fluid in brake system. Another is air in brake fluid system. Some ,but not all brake pads have squealers that let you know it is time to change pads, leave it too long and you grind disc away, then really expensive repair.

if your pads are squeaking its probably if not already to late to stop. you may need to bleed the lines but i can confidently say you need new pads, you lose alota pad when they get worn so you gotta press the pedal further to get friction.
well if you break and you hear a grinding noise then you need new pads.. sounds like you need more brake fluid, have one of your friends is knows about cars to check your brake fliud, theres a lil line on side of it itll say min and max, if its full, then you have air in your lines youll need to bleed your brakes
you could have a fluid leak somewhere, a bad master cylinder, or the rear shoes are way out of adjustment. worn brake pads do not affect pedal position. only drum brakes, low fluid, or faulty parts affect pedal position.
I agree, check the fluid first to make sure it has the required amount and then you can have your mechanic bleed the brakes. Fluid check and bleeding the brake systems shouldn't cost that much. In the mean time the mechanic is probably going to check the pad levels and let you know if you need new ones
You might check your brake fluid level and see how it is. You might be low on fluid.

Disc brake pads keep constant contact with the disc, which allows quicker stops because the pads do not have to move much, not like the old drum brakes which had to move to the drum and then add pressure. So discs are in contact all the time, so my guess is that the pressure is low in the brake fluid line, which keeps the pads touching all the time, and perhaps your fluid level is down. Your master cylinder should always keep the pads pressurized.

If not low on fluild, have your master checked.

Most brake pads have a metal tab that is not touching until the pads wear down, and then they start rubbing and making noise, telling you the pads need replacing.



added: And as Brian says, brake drums type brakes, if on the rear of disc brake cars, can cause low pedal, because of the clearance of the brakes to the drum, and they are not pressurized all the time like discs are. So bad rear brakes could cause the problem.
Find a Brake shop who offers free brake inspections! And get a few estimates while your at it and go with the lowest one. Sounds like worn pads and a rear brake adjustments.
