need brake fluid - check for leak in braks lines
that depends greatly on what is wrong with them.
You either got the wrong master cylinder or you haven't actually bled all the air out of the system.
i do not no
It sounds as if there is not enough pressure in the system. This could be the result of a faulty master cylinder, or inadequate brake fluid. It is also possible the piston assembly in the calipers have a fault.
Is it drum brakes? It's time for an inspection unless you just wanna replace the rear brakes yourself.
No you can not. If you do it can ruin your quad brakes and possibly your engine. If you do and something goes wrong you could have to spend a lot of money to get it fixed if that.
It could be your brakes. Your brake pads need to be changed out every couple of years or so.
I have to pump my brakes what čould be wrong

Bad ground, usually at the rear lights.
