    ty Arnie. I checked the fluid level it is full. Doesn't really look like anything is leaking around the master cylinder either. Is there any kind of relay or sensor that could've suddenly gone out like that?

SOURCE: Noise when making a slow speed tight turn.

noises during slow tight turns are usually CV joints going bad. A way to check, is to jack up one front wheel, set the parking brake, and put the car in drive without pressing the gas. Turn the wheel to both extremes, and listen for the noise. Repeat with the other front wheel (set the first one back down) and listen. Whichever makes the noise, is the side you need to change.

Hello, There are scanners made for the ABS system. There is valving inside the ABS unit which routes the brake fluid to the Calipers. It may be not so much that the right wheel is grabbing, but the left wheel is not braking.

There are also different methods to bleed the brakes. Some people like to pump them, some have pressure bleeders, some gravity bleed. I use a Vacuum bleed which seems to work good for me.
With a Vacuum bleed I can tell if one wheel is not drawing fluid or seems clogged. I just use the handheld Vacuum pump with the bleed cup attachment.

You should be able to jack the front up and have a helper pump the brake and spin the front wheels by hand. The action on the left and right side should be similar.

Before you go to use an ABS scanner, disconnect the ABS plug-ins and check for corrosion on the pins. Use a little WD40 or Electrical cleaner on the connections and then reconnect them and try it.
Remember to follow the pattern of bleeding the longest brakeline first. Usually the drivers front is the shortest line. All scanners are not equal, only the more expensive units have the ABS test function.

Good Luck with this, would like to know what finally cured it.

SOURCE: we keep changing the fuel

Hello, There is a Relay for the fuelpump and it should be in a Powerbox. It may be cutting off power to the pump. Before changing another pump, have someone check and measure the Voltage going to the pump. Also check your fuel pressure regulator.

There is another switch which you would need to reset if the car detects a big impact. It is called an Inertia switch and is usually in the trunk behind the carpet on the drivers side. Another location can be low in the cabin by the passengers kickpanel. I do not believe it is your problem. It will kill the power to the pump and you should be aware that it exists.

Under the hood there are a series of Relays in the Powerbox. That is why there are several terminals on each Relay. When you turn your Ignition key, it activates Relays which activate more Relays. This is the way the car knows different important parts are turned on. Unfortunately it becomes a liability when there is an intermittent short in the series of co-dependent Relays.

The last power wire to the fuel pump is what is important. You work backwards from there to find out where the power is being stopped if that is the case. If you have a little money to possibly waste, your car is a 1999 model. The Ignition switch could be worn out and disconnecting the power.

I hope my solution is very helpful to you.

Rough idle


Are you getting vacuum to the power brakes?You may have a vacuum leak at the power brake vacuum line connection at the intake or a defective brake booster allowing an internal vacuum leak and it's affecting your idle.Try blocking off the brake booster vacuum line as a test but don't drive anywhere unless you are ok with the increased brake pedal pressure needed without vacuum to the brake booster.

Brake lights on a cougar


Check fuse 24 in the interior fuse block. If that's good check the brake switch. There should be power on the violet/white wire all the time. There should be power on the green/orange wire when the brake pedal is depressed. If there is no power with the brake pedal depressed than the ditch is bad. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Abs brakes chirping noise, when pedal depressed,


worn out brake pads and slightly warped rotors. Most brake pads have small steel tabs that touch the rotor at a 90 degree angle when it is time for replacement. if you keep driving on the worn pads, it will stop chirping but that just means the tabs (also called wear indicators) have broken off and repair is about to get very pricey.

2001 Mercury Cougar, won't turn over


This will sound stupid but check to make sure all the bulbs, yes I said bulbs, as in brake and turn signals are the correct bulb. No kidding. I fought a problem like this in my shop for a week on a mustang. It had a wrong brake light bulb. Just a idea. See if it will start by jumping the 2 posts on the starter solenoid under the hood on the inner fender. It has two battery cables going to it. use 2 heavy screw drivers to do this. Do not tough the metal of teh screw drivers. The solenoid could also be bad.
