My break pedal goes all the way to the floor . I replaced brake rotors master cylinder, and Break booster. I had to bleed the brake and still pedal still goes to the floor


You still have air in the system.(not bled properly) If you let the Master cylinder drop down to nothing then you need to bench bleed that before bleeding the lines again.

How to bleed brakes?


If YOU DON'T HAVE AN AUTOMATIC BLEEDER GET SOMEONE TO HELP YOU. MAKE SURE THERE IS FLUID IN THE RESOVOIR. HAVE YOUR HELPER 'PUMP' THE BRAKE PEDAL NUMEROUS TIMES THEN HOLD THE PEDAL DOWN. STARTING FROM THE FURTHEST WHEEL AWAY FROM THE RESEVOIR OPEN THE BLEED SCREW SLIGHTLY TO LET OUT ALL AIR. CLOSE THE BLEED SCREW AND PUMP UP THE LINE AGAIN HOLDING THE PEDAL DOWN OPEN THE BLEED SCREW AGAIN UNTIL PEDAL GOES TO FLOOR. CLOSE THE BLEED SCREW AND REPEAT UNTIL NO AIR COMES OUT. MOVE TO NEXT WHEEL AND REPEAT. MAKE SURE YOU KEEP THE RESEVOIR FULL.

Brake pedal goes down normal then gets hard like there is air in line even after bleeding lines


Usually when there is air in the brake lines, the pedal goes to the floor.
If it is very difficult to apply the brakes, the problem may be the power booster.

Toyota surf brake problem


If you replace the wheel cylinders or brake calipers and did not bleed them properly, you most likely have air in the lines, If the rear brakes are drum brakes they need to be adjusted (if taken apart or new parts put on) or the pedal may sink when pressed.
1. If the brake pedal is soft when pressed down, the brake lines have air in them and need bleeding to remove the air.
2. a soft brake pedal can also be a bad master cylinder. Replace the master cylinder if the lines have been bleed correctly but the pedal is still soft or sinking when the pedal is pressed.

When i step on the brake pedal it goes all the way down, what's wrong?


You have air in your brake lines. Try inspecting the system for brake fluid leaks. Replace any worn out brake pads, scored discs, leaking brake piston seals, etc.Now place a clear tube on the bleeder screws, one at a time , and bleed the air out of the system with the help of a friend to push the brake pedal. Start at the rear wheel cylinders and finish with the front calipers. Once the air is out of the lines the pedal should firm back up.

Just got a new caliber, new brakes, brake fluid and my car wont stop


Did they bleed the air out of your brake system? Try pumping the brake pedal until it is "hard" then mash down on the pedal - if the pedal goes down but slowly, you probably have air in your brake lines.

My 94 c1500 has very spongy brakes.I have replaced brake booster,master cylinder,porportion valve and both rear wheel cylinders.brake pedal will get firm when applied too bleed brakes but not much fluid...


You still have air in the system. You will have to bleed more. I had to bleed a quart of brake fluid out of each wheel to get good brakes on my 1996 GMC.

How to bleed the brakes on a1999 chevrolet venture van instaslled new brake pads on front tired to bleed brake pedal all the way up when van not running - goes to floor when van is running


Start with brake in the rear that is the farthest away from the master cylinder ( if your master cylinder is on drivers side start with passenger rear,pump up brake pedal until hard have someone else open bleeder valve until air or fluid squirts out,while holding brake pressure even if goes to the floor dont release pedal until bleeder valve is tightened or you will **** air back into the line,do this several times making sure you get a full stream of brake fluid and no air,continue to other rear wheel and then proceed to front wheel furthest from master cylinderand then final wheel. if you still don't have brakes change master cylinder and bleed all brakes again.

Nissan 1400 champ front brakes binding, brake paddle stays high.


This indicates that you have air in the brake system or something isn't mounted properly. You'll need to inspect to see if there is anything not properly mounted, I'll deal with the brake bleeding:

You will need to bleed the brakes from the right rear first, then the left rear, right front, then left front brake, all without letting the brake Master Cylinder resivoir from getting low while doing the bleeding.

You may even want to start with the master cylinder to make sure it's bled properly by loosening the lines there first, bleeding them & then continuing to the system. Use the guide below for best results.

Bleeding brakes properly:
1. 2 people are required to do this properly, forget one man bleeders, they do work, but don't talk back or identify problems as they can't see what's happening. As a safety feature it's good to have another person nearby when someone is getting underneath a vehicle. Even my wife has had to do the pedal pushing in my household when I didn't have an assistant and needed to bleed either a brake system, or a clutch system.

2. Never let the fluid go beneath half way down when bleeding the brakes.

3. When adding fluid to the master cylinder, use a funnel to allow the fluid to run down the side into the cylinder, or use a syringe to prevent air from entering the fluid as you pour it.

4. Always pump the brakes slowly, release them slowly. Fast pedal action causes the fluid to rise into the air, allowing air to enter the system.

5. Pressurize the system by pumping repeatedly until the pedal is as firm as it will get, continue to hold that pedal down until the person bleeding the brakes, has released the air by loosening the bleeder valve, then make sure the line is tightened BEFORE releasing the brake pedal slowly. Pump the pedal again to build pressure, & bleed the brake again the same way until air stops coming out & only good fluid is seen. Proceed to the next farthest line.

If done this way, the brakes will be properly bled and if there are no leaks, the system should work properly. If you identify a leak, repair and start over.

good luck

How do I bleed air from the brakes


Two persons are required: one to bleed and other to press brake pedal.
Remove wheel and hub of the side you want to bleed. You will find the bleed nut there. Open it a little until some oil flows out. Ask the other person to press brake pedal with steady pushing and withdrawing until he feels its tight while you slowly tighten the nut. Adjust tightness of pedal by trial. Don't forge to refill the brake fluid after bleeding all the brakes.

Do give my solution the highest rating if it solves your problem. Thank you for using fixya!
