Default brakes

i have a question...i am wondering what is wrong with my brakes...i notice that like if im going 30 and i go to turn i push on the brakes...then liek when im slowing down i can feel like something give (possible air bubble in the lines) and i have to push harder to slow down at the same rate i was slowing down at...and when i slow down even more it does it again...so when i come to a stop i almost have to push the brake level as hard as i possibly can to stop...i am wondering what could cause that and if the brakes just need to be bleeded or what?

The most probable cause is an internal leak in the master cylinder. You would not lose fluid in that case, but the pressure forces fluid past the piston, instead of down the pipes to the brakes, and your pedal (and piston) just keep on travelling to the floor.

I am not sure if it is possible whether wheel cylinders can also leak internally and not lose fluid.... usually they just leak out into the wheel..... but your wheel hissing might suggest having your wheel cylinders checked out...

There may be some kind of indication if you just take that rear drum off and take a look. Nothing should be wet.

Check for a leak in your rear air shocks or fittings. This will not cause a brake problem though. A tire going down will because of ABS confusion.
