Nissan vehicle have a problem in the bleeding of the brake and as a result pressure bleed is more effective that the normal method
Take the vehicle to an accredited brake shop and have the brakes pressure bled or have a proper diagnosis done to find the fault

Brake pedal goes to floor


for the pedal to go to the floor there is still air in the brake system. Start again starting from the longest line bleeding each in turn to the shortest line . make sure you have adjusted up the rear brakes before bleeding as every time you press on the pedal the shoes expand right out and when you take your foot off the pedal the shoes go all the way back in. adjust them manually and do not rely on the self adjuster as it only adjusts on wheel movement

1999 corolla, brake pedal goes to the floor. how can we fix the brakes?


is the abs light on?the abs system only effects the pedal when you are stopping quickly to activate the system. you still have a hydrualic brake pressure problem. are the rear brakes shoes or pads? rear shoes out of adjustment can cause a low brake pedal.even though the master cylinder has been replaced doesn't mean you got a good part.if the part was a remanufactered part very likely it is bad. to determine if it is the master cylinder, plug off the lines from the side off the master cylinder and hit the brake pedal. if the pedal stays up look for a problem elsewhere in the system. if the pedal drops the the master cylinder is defective.

I have a 03 ford taurus the break pedal gose to the floor after changing the rear breaks and the front pads and after changing the master cylinder? what else could b the problem


You've done major work and now you'll need to completely bleed air out of the system, to get the fluid to go all the way through. You may also need to adjust the rear brake shoes.

First, bleed the Master cylinder to get fluid through it. This should have been done before installation. Loosen the lines at the M. Cylinder and fill up the reservior with brake fluid. Pump the brake pedal slowly with the cover on the M. Cylinder to prevent fluid from splashing out. Once you've got fluid coming through the M.Cylinder, tighten the brake lines at the M. Cylinder.

Bleeding the brakes is a 2 person operation. You always bleed the brake the farthest from the master cylinder, then the next, the next, and finally the drivers front brake which is the closest to the M. Cylinder.

If you are unfamiliar with this process, you need to remember that you can't let the brake fluid get low in the M. Cylinder, or you have to start all over when air gets back into the lines.

When one person pumps the brakes, after several pumps hold the pedal down as far as it will go and keep pressing to the floor as the other person loosens the bleeder valve. Don't let off of the pedal before tightening the bleeder valve. Then repeat until all of the air is gone.
Teamwork and communication. Both of my wives were able to assist me in bleeding brakes.

You will have to add fluid and repeat this process until you have a firm pedal.

One man bleeder valves work if used properly, but who tells you what is happening at the other end while you're pressing the pedal?

Good luck.

Your brakes are vacuum aided so when engine is off the pedal will be hard. When the engine runs the vacuum is active and the pedal becomes light. Your brakes are working but need adjustment so that the pedal does not go to the floor.
Locate the adjusting screws behind the rear wheel drums.
With one wheel jacked adjust the shoes till wheel wont turn.
Then loosen until wheel is just free of any friction from shoes.
Repeat for other side.

Brake pedal is mushy all the way to the floor. Have already replaced front calipers, master cylinder, and bled all the brakes. Pedal still goes all the way to the floor when stopping the car.


If the car has drum brakes in the rear, Jack the rear up and have someone push the brake pedal hard and you try to turn the wheel. If you can turn it you need to adjust the rear shoes. They may be traveling out so far that the fluid level drops causing the pedal to go to the floor. You must adjust them with the drum on till you hear and feel the shoes rubbing against the drum. Hope this helps.

It sounds that you have done a pretty good job at this point. Remember that the brake adjustment will dictate the amount of brake pedal. Recheck to make sure the right brake linings were used. Recheck to make sure the brakes on the rear are adjusted up as far as possible. As far as the bleeding, I have had many cars that will not bleed the sytem without the engine running to give it the pressure needed to pass through the master cylinder and lines. Have a WELL ventilated area, car in neutral, wheels chocked, and bleed the brakes with the engine running. Remember to take all safety precautions to avoid injury before attempting this.
