The other day my brakes went out as I was going downhill then when I backed up they worked again. I was told it might be the brake cylinder. My friend put in a new brake cylinder from O'Reilly's and now it is doing the same thing again. What could be wrong? I get pull push and pull when the car is off but when it is on I get nothing but to the floor.

Hi and thanks for using 2CarPros.com.

Are you certain there are no leaks? When you say brake cylinder, are you referring to the Master Cylinder or a wheel brake cylinder? Was the system properly bled?

Take a look through this link and see if there is anything that you find helpful.

Let me know if that helps or not. If you have other questions or need more information, let me know.

Take care,
