If the brake master cylinder reservoir is full of brake fluid, and you haven't had to add any recently, then you probably don't have any air in the lines but may have a bad master cylinder that isn't capable of building up fluid pressure. If you've had to add brake fluid recently because the system was low or empty then you may have both air in the system and a leak that is allowing brake fluid to escape. Possible spots it can leak are at brake hoses, brake lines, wheel cylinders, and brake calipers, just to name a few. Either way, don't attempt to drive a vehicle without good working brakes as it is very dangerous to do so. I would have a good shop check this one out and give the entire system a thorough checking over to find out what has gone wrong. Good luck, hope this helps a bit.

Why did my Ford Ranger make a frying noise under the dash close to brake pedal after the pedal was pushed and went all the way to the floor?

Hi,

please first open your hood and check if there's any type of fire or smoke coming out from the area close to where you heard the sound. If not, then it might be two materials rubbing between each other that are not supposed to be touching.

Please work with a mobile mechanic to properly diagnose this issue.

Thank you.

Having trouble bleeding brakes for 2009 jeep wrangle 4wh drive when car is off the brakes seem fine , but when the car is on the brake pedal goes almost to the floor

Because when you start it the brake booster will start working, start bleed on wheel farthest from master cylinder and work closer, one at a time pump up and bleed each line at least once after you don't see air anymore...

Jeep brakes

It is very difficult to diagnose this problem with the little bit of information you gave. If the brakes are drum brakes check to see if the brake cylinder is working and has no leaks, lift the rubber seals and make sure there are no leaks there, check the brake adjuster make sure that works okay. If everything works and you bled the brakes properly, then the problem is most likely is the master cylinder or the wheel cylinder.



While bleeding the brakes always make sure you check the master cylinder reservoir to make sure the fluid level is up so you do not get air in the brake lines. When bleeding the brakes did you have someone press down hard on the brake pedal hold the pressure on the brake pedal when opening the bleeder then push the brake pedal to the floor keep it there, until you tightened the bleeder, then pump the brakes up and hold it there, while you repeated the bleeding operation by opening the bleeder when the brake pedal go\'s to the floor keep the pedal down until you tighten the bleeder and then pump the brake pedal back up then check the fluid level in the reservoir, keep doing it until the brake fluid shows no sign of air.



If the brake pedal is pumping up during the bleeding process and you made sure you got all the air out of the brakes and then the pedal go\'s to the floor, make sure the fluid level is correct in the reservoir and the bleeder is closed tight and there are no leaks in the lines, wheel cylinder, brake cylinder the brake adjuster is working and master cylinder, and if you still have no brakes then it must be a defective piston in the wheel or brake cylinder, if there is a seal problem with the pistons you will not get any pressure to push the brake fluid. let me know how you are doing.

The brake pedal goes all the way to the floor and the car will not stop. I was told it was the module but im not sure what it looks like or where it is to purchase a used one.

Have you checked the brake fluid level? It may be empty. There may be air in the brake lines. You may have a bad slave cylinder, caliper or master cylinder. Don't really know what kind of "module" would cause the pedal to go to the floor. Sounds like someone making stuff up.

I change breaks pads on my 08 jeep compas after that i push pedal breaks end not i dond have pressure on pedal way? thanks

sounds like you got air in your brake lines from where you changed your pads thier should be a bleeder valve on your brakes get a friend to hold the brake pedal to the floor while you take a wrench and break the valve open when the pedal hits the floor close the valve just continue doing that until pure brake fluid comes out without air bubbles start at the master cylinder under the hood and don't stop until you have done all four corners if that doesn't fix it you might need a brake booster

Brake problems! getting fluid to all lines no air in lines but pedal is almost touching the floor

Air can be a pain to get out sometimes. Check for striped fitting/bleed screws, if it all check out, it is most likely the master cylinder on the firewall.

Brake Pedal goes to the floor in my 1990 Chevy C1500 Scottsdale

do you have a self bleeder kit? first off, you have to bleed the master cyl back into its self and the combination valve before you go to the wheels. when you do that, I think you will find that you have air in the lines. disconnect both brake lines from the master cyl and put the bleeder kit fittings on the master cyl, then put the rubber tubing with the kit on the fittings and submerge it in the brake reservoir. make sure its full. then pump the pedal until you get a hard pedal. if that is the case, reconnect the lines to the master, then have an assistant pump up the brake pedal with the engine off, and bleed the combination valve which should be connected to the master by steel tubing. pump it up, then hold it down, and crack the fittings loose, one at a time until the pedal goes about half way down, but do not release the brake pedal until the line is tight again, otherwise you will **** air in the lines. after you do all that, go to the farthest caliper or wheel cylynder from the master and bleed that with the same technique,and dont release the pedal until you close the bleeder screw. unless you have a major prob, this will work.

Replace brakes. now they go to the floor. bled air

When you fixed the brakes, did you take the lid off the master cylinder. I just wonder if you spilled out your brake fluid. The only reason the pedal should go to the floor is if the brake fluid is gone or the master cylinder is not working. Check the fuse. Check the brake fluid level. The pedal only goes to the floor if there is no back pressure in the lines between the master cylinder the lines to the brake pistion on the calipers. Please give me a good ratin and keep me informed.

Brakes are spongy,light keeps coming on,even after bleeding them

If there are no leaks from wheel cylinders, calipers and lines, likely there is a bypass condition in the master cylinder. If so, replace it.
