First, make sure the master cylinder is filled with brake fluid. If it is low, there may be a leak somewhere in the brake lines or a brake cylinder. If the master cylinder is bad, you can normally pump the brakes up, but the pedal will slowly sink to the floor again. The master cylinder needs to be replaced or repaired.
The parking brake is set by pushing, with your foot, the parking brake pedal on the left side of floor area. It is released by pushing with foot again.
When you press and hold the brake pedal it will slowly move to the floor. It can also have a catastrophic failure and go straight to the floor with no stopping ability at all. If you hold the brake pedal down and it slowly moves to the floor any at all, replace the master cylinder.
Small pedal on the left of the brake pedal - activates the rear brake to hold vehicle
usually they will leak out the back by the booster, your brake pedal will slowly go to the floor at stops or the brake pedal will go right to the floor when pushed.
Something is impairing the brake pedal to go to the floor. Only a mechanic can tell you what is happening.
no you have a brake fluid leak somewere
I suspect it is because the pedal return is weak. My Park Avenue does the same thing. I can lift the pedal with very little pressure from my toe and the indicator goes off.
You are probably losing both brake fluid and pressure through either a wheel cylinder or the Master cylinder . You will need to have a trained mechanic look at why you are having the loss of a brake pedal .
ouch,are brakes adjusted correctly/ sit in vehical and pump pedal to get a full pedal,then hold pedal to see if it bleeds off and goes to floor,if it stays, replace shoes and pads if it goes to floor, there is a fluid leak somewhere is there brake fluid in the resevoir/ are there any brake fluid leaks ,check backside of wheels there is a brake fluid pump, on the chassis rail about level with the front of the front door on the left side.if this pump is bad your pedal will go to the floor
press back down on the pedal
check the brake light switch on the brake pedal
probably have broken parking brake cable.
