Brake peddle hard but goes down slowly?
Air in a brake line or a bad master cylinder could cause this. Bleed the brake lines if you have been working on any brake cylinder. If this happened without any warning, the master brake cylinder is probably the cause and should be replaced.
What could cause fluid on my driver side floor board?
Your brake master cylinder may be leaking. Have it checked by a technician.
What could cause the brakes and brake pedal to stick when brake pedal is pressed?
Check around brake pedal for something rubbing. If OK, I'd look into the master cylinder.

1991 Pontiac grand am stalls even after master cylinder replaced?
The brake master cylinder has nothing to do with the way the car runs. It certainly wouldn't cause it to stall.....Maybe the brake booster?
Why does brake pedal go to the floor?
Normally this is caused by a Master Cylinder that has failed. Replace the Master Cylinder. Normally this is caused by the loss of fluid in the brake system. The fluid reservoir needs to be checked first. It possibly may be caused by a bad master cylinder but the most common cause is loss of brake fluid.
Is a small amount of power steering fluid mixed in with the brake fluid harmful?
Yes. It will cause the seals to swell up in the master cylinder. This will cause a loss of braking. You need to remove the fluid and flush out the master cylinder(with clean brake fluid) immediatly.
Why is your brake pedal soft?
Brakes probably need to be bled especially if you have recently had any work done to them..A bad master cylinder could also cause this.
What would cause brakes to suddenly go out completely?
Any sudden brake loss can be the cause of 1. brake line damage 2. master cylinder disfunction
Can the brake booster cause your brake pedal to go to the floor?
No, a busted brake booster will not cause the brake pedal to go to the floor. It will however cause the brake pedal to be extremely hard to push. A defective master cylinder will cause what you describe. Replace the master cylinder and bleed the brakes. It can because it happened to me. The booster lost vaccum and the pedal went to the floor. Sorry, you are wrong. The only reason the pedal went to the floor was because the master cylinder failed. The brake booster only boosts the pressure on the master cylinder and allows you to not have to push so hard on the brake pedal. Cars of yesteryear did not even have a brake booster and they stopped just fine albeit you had to push the pedal allot harder than with power brakes. A failing brake booster will not cause your pedal to go to the floor although it might cause it to go lower than normal before the brakes apply. As long as the master cylinder is good you will still have brakes, but you will have to really push hard and might even have to pump them up in order for them to stop the car.
Why do your rear brakes on your S10 have no pressure?
Usually, a loss of pressure in your brake system means that there is a hole somewhere in the system. A leaking brake line or a punctured reservoir could cause a loss of pressure. A bad master cylinder could also cause a loss of pressure in the back brakes.
