Preferably, every part bike brakes squeak a rim-brake system is rigid except the brake shoes.

Most of the motion of the bike brakes squeak levers is wasted in flexing zqueak arms. If the mechanical advantage is high, the brake lever will go to the handlebar before the brake shoes grip the rim very hard. If the mechanical advantage is low, the feel at the levers will be harder, but the brake bike brakes squeak never develop enough grip. See also Jobst Brandt's comments on brakes.

Having the brakes properly bled will minimize the chance of this, but it can still happen. Oil systems have a lower boiling point, but do not absorb moisture. Dot fluid systems have bike trail long island higher boiling temperature, but over time the fluid absorbs moisture from the atmosphere, lowering the boiling point. And yes, even dot fluid systems can boil, I have had squak happen riding dirtbikes, never on a bike though, all the sudden, you will have zero braking when you pull the lever like someone cut your line, the good thing is that as long as you didnt cook the seals, you can usually let things cool oma bike and the brakes will come back enough to get back to the car.
