Outside air leaking in by driver's feet

How to stop outside air leak, near brake pedal. Carpet covers what looks like a hydraulic line, which penetrates the carpet through a slit. Air leak seems to be from the area where the line goes up to the engine compartment or in front of it. Can't see anything obvious. What should I lok for? Is there a vent that needs to be closed?

Some cars, and maybe yours, have positive air flow built in to the heating and air conditioning system. That means as long as the engine is running, the blower fan is running at low speed to circulate air into the car. Perhaps that is what is happening in your case.
That line of which you speak probably had a rubber sealing-gasket around it at one time.
I might think something knocked the plug out.
First thing that pops into my mind is, was the car ever in an accident?
If you definitely find a hole in the floorboard or firewall, you might take something and try to plug it up yourself, like a piece of a sponge, some plastic, some putty, or something else.

well, from what you told me, more then likely it's the thermostat housing gasket is shot, or the hose connected to the housing is loose.

SOURCE: how do you remove the front passenger seat? need

Your AC overflow is clogged up, it needs to be cleaned out. It is a little rubber hose sticking through the fire wall on the passenger side up front, bugs and dirt get in there and clog it up, then the ac will flood the floor. The seat can be unbolted from the floor and lifted out, these bolts are fine thread and high torque, meaning it takes a while to get them out, if you have an air ratchet , use it. The chair is probably wired down, so don't forget that when you have an arm full of chair and can't move. Hope this helps.

Testimonial: "Many Thanks-I am going to attempt to remove the seat w/o an impact tool. If successful I will also remove the airbag module, any thoughts on a less expensive source for one? Buick garage wants $355.00 for one. "

03 F150 spongey brakes after replaceing brake cylender and bleeding brakes?


This sounds like a bad brake line, these trucks are famous for rotted lines behind gas tank, make sure there are no leaks, this sounds like a leak or a defective master cylinder, if this is the same problem then i would say it is a line also check the rear brakes for leaking wheel cylinders unless you have rear disc brakes, check calipers for leaks.

Take a good look at brake system for leaks, hold brake pedal a few times and let is sink to floor , do it about ten times and then look for a leak, good day

I have a 96 f150 4x4 i hve bleed the brakes over and over and the pedal justs goes to the floor when runing


You need to have the ABS hydraulic control block bleed, that takes a special tool only the dealer or a well equipped brake shop has. You can't do this at home the tool cost a bloody fortune.

Losing brake fluid with no leak


It's a sealed system, so it's got to be going somewhere, leaking somewhere (or boiling off from severe braking operations over and over). Since you likely haven't experienced extreme braking, it must be leaking somewhere.
You will have to trace all your brake lines from the master cylinder to each wheel to check for any sign of leaking. Front calipers are easy to spot leaks when they leak. If you have drum brakes on the rear, you may need to pull off the drum to check the wheel brake cylinders. Peel back the rubber boot on each end of the wheel cylinder and look for any fluid leaks there.
Another place to check is at the back of the master cylinder. If a seal is bad there, it has been known to leak fluid inside the car, under the dash. Feel around the carpet under and behind the brake pedal for any wetness. If you find brake fluid there, you will need the master cylinder replaced or rebuilt.
Hope you find the problem. Don't forget to check the ABS system and brake lines, too.

I hit my brake pedal and felt it bleed off but there is not no line infraction or leaks after checkout but still having to replace brake fluid. The breaks are soft and go plum to the floor for some reason


If you are having to replace brake fluid after you've filled it and bled the lines to remove air you have a brake line leak somewhere. I suggest following the break lines (probably 2 of them) from the Master Cylinder to the ABS unit. If there are no leaks then follow the other 4 lines coming out of the ABS to their respective wheels. The disappearing brake fluid has to be going somewhere, try putting large pieces of cardboard under your vehicle to check for drips, this may help in locating the leak. Also inspect the caliper area as brake fluid could be leaking from there as well. Please remember: PLAY IT SAFE!! Don't drive a vehicle with improperly working brakes! Stopping is the most important part of driving!

I have a brake line leaking from the back but I need to pinch it off so I can drive it to the garage for repairs , what line do I pinch off from the master cylinder so I just have front brakes.


Tricky and risky ,and if garage is not to far away, use the parking brake and brake pedal at low speeds to stop. Taking out of gear at stops at a light or crossing/stop sign. Otherwise, cap and plug the main line at rear axle brake tee spliter from front.

Break peddle to the floor no resistence behind it, and not stopping well, no noise.


First of all, don't drive with the brakes this way...
Sounds like you've lost the hydraulic pressure in the brake system.
Check the following:
1. Open the hood and check the brake fluid reservoir to make sure it's full of brake fluid. If not, top it off with the recommend brake fluid.
2. Try the brake pedal again, with the car running in PARK, press a few times and see if the pedal "firms up".
3. If it does, press and hold the brake pedal with the motor still running. Look to see if the pedal slowly sinks to the floor or if it's a bit "mushy" or feels ok.

If the pedal sinks to the floor, you've got a major leak in the brake system. This could be from one of the wheel cylinders, from the disk brake caliper piston, a damage brake hose, brake line, a faulty master cylinder, power brake booster.
The best way to check is a visual inspection. Look around each wheel- look for fluid leaks, for signs of fluid where you park, on the axles, under the hood near the brake fluid reservoir, etc.
If after the fluid is topped off, you get a mushy pedal, I would suggest getting the brakes "bled". Bleeding the brakes simply means getting all the air out of the brake lines. (Air compresses where brake fluid won't- if the pedal is mushy it's got air.)
If you've not done brake work before, I highly recommend taking it to a local mechanic to help you out. You really want to KNOW that your brakes are going to be there when you need them. So if in doubt have a mechanic check it out.

2004 holdern rodeo v6 clutch went to the floor was working all good before


The problem could come from the clutch master cylinder or the slave cylinder. The cause could be external or internal.

First check the fluid level in the reservoir. The reservoir could be independent of the brake system or using the same.

If the level is too low, air may have entered in the line and the hydraulic compression is affected. So first, adjust the level in the reservoir using recommended oil. (normally brake oil is ok).

Check for any oil leak starting from the clutch pedal following hydraulic circuit up to the transmission.
Your vehicule should have two clutch cylinders: the master and the slave.
The master cylinder is operated by your clutch pedal, it's located under the dash, fixed to the firewall and connected to the hydraulic line on the other side of the firewall. Check for any leak on the carpet, under the carpet and near the hydraulic connection. Pumping the pedal making that verification could help to detect leak. Then follow the hydraulic line going to the slave cylinder attached to the transmission making a visual inspection for leaks.
If for any reason some air entered the circuit, the line could be purged from air bleeding the slave cyclinder as you do bleeding brake component.
If there is no air, no leak detected then it's probably an internal problem that you can't see. Remove the cap from the reservoir, depress the pedal. If the oil is moving in the reservoir then the master slave is probably bad otherwise I would suspect the slave.

Some other Gurus could complement or correct my saying.
Hope it will help
