you either need a new brake master cylinder or your brakes need to be bled
look for man, bird, sea, and then a last one then before it brakes, grab the rope.
No
(1)there is a leak in the system, (2)fluid reservoir is low, (3)air in the lines.
you either need to bleed your brakes, add fluid or get a master cylinder darrellshandyman@live.com
You either got the wrong master cylinder or you haven't actually bled all the air out of the system.
Caliper slides frozen? Rear drum brakes? May need to be adjusted
apply the floor striper
Check the caliper slides (may be frozen) should slide freely to compensate for brake pad wear
No, that is certainly not normal. It means that there is an air bubble in the hydraulic brake lines or if there are drum brakes, they aren't adjusted right. ==Additional comment == !!! Get that fixed ASAP, it's VERY dangerous.
Master Cylinder internal seals are failing. Replace the Master Cylinder before you have an accident when it fails permanently.
The best way to tell when you need brakes is by squeaking, when the brakes are rubbing against the metal, when your brake pedal goes all the way to the floor and when you are running out of break fluid.
How is your stopping distance, how far do you push the pedal to the floor before anything happens are two good clues. Also the term "need new brakes" is way too vague. - They may need to be bled or you may just need new front pads.
