Question type: Maintenance & Repair

Now I have change my brake lines, I still have problems.
When my car is off the brake pedal doesn’t go all the way
to the floor. When I turn my car off it goes all the way
down to the floor. And I don’t know what to do, the only
thing Inthink it can be is that the master cylinder is bad.

When you pump the brake pedal does it firm up? When you turn engine on vacuum to the booster can make a brake pedal sink if there is any air trapped in the lines. If you can pump up pedal and they feel firmer, I'd suggest you still need to bleed the lines. If it just slams to the floor and no amount of pumping builds up pressure then likely a MC.
