Why Does My Brake Pedal Go To The Floor. There are two different kinds of brake systems. Presumably it is putting the brakes on when this happens.
It will only come up if you turn off the vehicle or unhook the vacuum line on the brake booster. Another possible cause is a bad brake master cylinder. Posted on Aug 12 2010.
You cannot pull it up.
If after bleeding several times the brake pedal still goes to the floor board the master cylinder may be determined to be bad. As you press the brake pedal a valve in the servo opens to allow the vacuum to pull against the diaphragm in the servo to assist you. When youre out of brake fluid your brakes simply wont work. A brake pedal that sinks all the way to the floor could indicate a problem with the brake master cylinder or it could be due to a brake fluid leak.
