Question about Ford Mustang

2 Answers

Front and rear drum brakes, the pads are ok, but the brake pedal started going to the floor. When I tried to bleed them, the rear bleeder screws broke. So I replaced both wheel cylinders. The rubber hose in the rear that attaches to the axle, had been pinched, so I repaired it with a hose connector. I have bled all four brakes in the correct order, but the pedal still goes to the floor. Could there still be air in the line or does it sound like something else? I'm not losing brake fluid anywhere because the reservoir is still full.

OK........as you have stated that you have bled the brakes properly.....was there fluid coming out each bleed nipple as a flowing stream...????

And did you shut off the bleed nipple half way down stroke....?????

If this is all ok, then I would be looking at a failed master cylinder.......and what is occurring is the fluid is leaking from the primary to the secondary within the master cylinder !!!!!

Bleeding 02 toyota sequoia


You have a helper pushing on the brake pedal when you open the bleeders? Is fluid coming out of the bleeders when you open them?

typically you will start at the right rear, then left rear, then right front, then left front. or work your way from the farthest bleeder to the nearest bleeder to the master cylinder. Make sure the reservoir does not go dry or you will have to start over.

It is possible that when you pushed the pedal to the floor the seals in the master when through some debris and where ruined.

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.

Brake pedal soft after changing pads and bleeding brakes


You will need to bleed the brake system. I would start with the rear brakes lines and work towards the front.You must have key off engine off when bleeding brakes, apply pressure on brake pedal 10 times and hold. The brake line is now ready to be open. Open and let the stream of fluid come out and close the line tight. Then release brake pedal once bleeder screw is close. This procedure must be repeated twice front and back. After, brakes have been bleed pump the brake pedal before putting in drive.
Note: Don't let the resevoir run low on brake fluid. This will cause air bubbles to accumulate on the brake system. Always top off before opening bleeder screw.

Is their a bleeder screw on the master cylinder on my 1999 grand am ?


If you have tried EVERYTHING, then you should have found the solution by now!.....Just messin' with ya :)

On a more serious note: What you need to do is a RADICAL brake bleeding procedure. You have air trapped in your brake system - most likely in the anti-lock hydraulic control unit if your vehicle is equipped with one.
Here's what to do: Take the top off of your brake master cylinder and make sure is is full to the top with brake fluid. Then go to the RIGHT FRONT wheel and open the bleeder screw on the caliper. Slowly pump the brake about ten times WITHOUT closing the bleeder screw. I know, this goes against the general instructions for brake bleeding which tells you to push the pedal down then open the bleeder screw and hold the pedal to the floor until the bleeder is closed - you will just have to trust me on this one...

Anyway, once the pedal has been pumped about ten times, check the right brake caliper and see if there is a steady flow of fluid running from the bleeder. If not, pump it a few more times. If there IS a steady flow running out, close the bleeder, top off the fluid level in the master cylinder and move to the other side and repeat the process. Once you have the brakes bleeding on their own really good (gravity bleeding - steady flow) THEN close the bleeder screws and give the bleeders a round or two by the conventional method (have a helper to push down and hold the brake pedal while you open, then close the bleeder).

If the pedal is still feeling a little spongy, you may have to also bleed the rear brakes in the same manner, starting with the RIGHT REAR. (Always start with the brake that is the farthest from the master cylinder.)

This should take care of the problem. Let me know if you need further assistance.

I changed the brake pads but the brake pedal goes alway to the floor itried bleeding the driver side tire but every time i step on the pedal with the bolt all the way tightened it is still sucking in air....


Normally changing the brake pads doesn't require brake bleeding.

If the valve is tightened all the way clockwise and it is still drawing in air, you might want to get a new bleeder valve from the Help! section of the auto parts store or via some online parts house.

There are several ways to bleed auto brakes.

  • Most auto parts stores sell 1-person bleeder devices that have a check valve at the end of a hose that fits over the bleed valve. These work so-so in my experience.
  • Another option is to use a vacuum bleeder to **** air and fluid out of the brake lines at each corner. The one I tried worked so-so.
  • So far the best method I've found is 2-person. One person holds the brake pedal down while the other releases the bleed valve and closes it up again. Some folks suggest repeatedly pumping the pedal prior to bleeding others recommend against it. I had the best result without repeated pumping and by slowly depressing the brake pedal rather than quickly slamming it to the floor.

Lastly, the correct order in which to bleed brakes is starting at the wheel farthest from the master cylinder (usually the right rear) and working your way closer (left rear, right front, left front). You have to bleed ALL four corners.

Also, if your vehicle has both drum and disc brakes, it most likely has a proportioning valve. You'll need to check the service manual or Haynes/Chilton manual for instructions on how to bleed. On my 86 Jeep I have to prevent a pin on the valve from moving, for example.

There's still air in the lines, just open the bleeder screws all of them and gravity bleed them , take the resovoir cap off and make sure you keep fluid in it . This may take some time but you will be happy when done. If you bleed them with a friend do one at a time pump the pedal, keep pressure on pedal and open the bleeder screw. when pedal goes to the floor repeat the process until its only fluid that exits the bleeder. Repeat this for the rest of the bleeders.

How to bleed brakes on a 1992 Chevy Caprice. Specifically the rear drums


start from the fartherest place from brake master cylinder, that will be the rear passenger side wheel. it takes two people to bleed brakes. you will find the bleeder valve screws at the top of inside of the rear drums on both rear wheels, have someone pump the brakes up, will take at least 4 pumps of brake pedal, at 4th pump keep pressure on pedal while you break loose the bleeder valve on the rear wheel, fluid will come out and brake pedal will go down to floor, keep pressure on brake pedal until you've tightened the bleeder screw back [note] you'll only have to back the bleeder valve out about a half turn until you see the fluid come out. after you've done the rear brakes add brake fluid to the master cylinder as it will be low. then go to the front passeger side and you will find the bleeder screw on the brake caliper. repeat the same proceedure as back. remember that pressure on the pedal is a must until you've tightened those bleeder valve screws back or else it will **** air into the brake system. suggest that you bleed all 4 wheels not just the back. after you've bled the front make sure you add more brake fluid back to the master cylinder, it will be low again. hope this helps and thank you for choosing fixya.com

When bleeding you start at the rt rear to left rear to rt front to left front always checking to make sure master stays with fluid, also start by removing one bleeder at a time and make sure the hole is clean and free of dirt brake clean should flow through, do this to all 4, then have someone pump pedal 3 times and hold then open bleeder when you close bleeder tell them pump again three times, do this all around until you have a good pedal, also check for leaks after bleeding, may have bad rusted line or bad master but bleed each wheel good first.dont worry about pedal going to floor everytime, just make sure fluid flows out of all bleeders when bleeding. hope this helps.

Replaced frond brake pads, brakes now go all way to floor, tried to bleed but cannt get brake pedal at all. Some fluid coming out of bleeders during bleeding.


you shouldnt have to bleed anything when just doing brakes,unless you opened the bleeders and this did not have to be done, if this is what was done then bleeding is needed,close all bleeders, have someone in car, pump pedal 3 times and hold down open bleeder tell them to keep preasure on pedal as it goes down then close bleeder and then tell them to pump again and hold do this a few times on each side starting at the right rear wheel then to left rear then right front then left front always keep an eye on fluid level in master cylinder always keep it full, dont let it empty, bleed all wheels,

1999 Chevy Tahoe- Soft Brake Pedal


Try having the dealer flush and bleed your system. It is very hard to bleed ABS systems yourself and have safe brakes that still work afterward. Bleeding non-ABS brakes yourself is easy not the same for ABS brakes. Valving, sensors and what-not require a tech and the correct equipment in my opinion. You do it wrong and you could ruin your ABS system. Do that and see if they firm up. I replaced my brake shoes/pads at the same time all new everything in back, drums/springs everything and new rotors up front. then I had the chevy dealer flush, refill and bleed system. Stiffer pedal and brakes work better. Keep in mind the brakes on 99 Tahoes are inaedequate, require new rotors often, heat up and fade/glaze pads regularly. I replace my pads long before they wear down because they glaze up and start fading early. I'll rough em up once maybe, next time, new ones. Every two brake jobs, new rotors for me. Just how it is. They will stiffen a bit and work better but they will never be awesome brakes. Just how it is on 99 and earlier Tahoes. Hope it helps. Very important to bleed correctly though. I'll bleed my 83 Toyota 4x4 myself but not the Tahoe.
