sounds like tired oil/ worn pump/ dirty filter/ ask yourself if you did your maintenance, if not bill has come due To be honest, Those are all very good reasons for why your Oil pressure drops down to 0 when your stepping on the brake, but the most commin reason for that is that when your stepping on the brake, your actually creating a "G" force that sends the oil in the Crank Case to the front of the car against the inside of the Oil pan. What this does in turn is not keep your oil pickup tube submerged, thus not allowing your oil to be "Sucked up" through the tube. This will instantly put air in the line creating a "0" reading for your Oil Pressure, when you come to a complete stop or when you are at cruizing speeds, the oil is leveled out pretty much allowing your oil pickup to remain submerged and keep a steady reading. This is why when you are at a stop or cruizing your Oil reading comes back instantly. You might ask, "then why doesn't it do the same thing when I accelerate hard, pushing the oil to the back of the pan and allowing the oil pickup tube to become UN-Submerged again, thus creating a "0" psi Oil pressure reading." Well, there is a good answer for this also, the reason for this is because is some cars the Oil Pickup Tube is actually located at the rear of the oil pan, so in return, when your jumping on the throttle hard, pushing the oil to the back of the pan, you are actually making the Oil Pickup Tube Super Submerged and maintaining your oil pressure. In most cases the oil pressure will remain around 60-80psi depending on throttle position in most cases. The easiest fix for this problem would to be: A... Check to make sure your Oil Level is where it is supposed to be. B... Add Oil to the engine even if it is at its optimal level, not more than a quart tho, just enough to top it off and keep that little extra oil in the pan to maintain the proper reading. This issue MUST be fixed or you risk the option of possibly RUINING YOUR ENGINE BY BLOWING IT UP. An engine that lacks Oil Pressure Often will brake a piston connecting rod, damage the piston itself, ruin the crank bearing, ruin the top end bearings/seals/and any parts that rely on oil to keep them lubricated enough to reduce friction to the point of avoiding overheating and scarring of the metal surfaces. Hope this helps you and anyone else out as much as possible! I have been in the Automotive repair field for a while now and have come across MANY oil issues so you have good reason to trust my "Words Of Wisdom". : )
30 psi from the doorjamb decal on my 1995 Cougar.
The brake system was not that secure
Remove the tire and wheel from your 1994 Mercury Cougar. Remove the brake spring and brake caliper. The brake shoes will come off.
with your eyes
The normal tire pressure for a 1997 Cougar should be 32 psi. The tire side wall has the exact rating for the psi stamped into it from the tire factory.
the average car is 32 PSI
You can find the 1997 Mercury Cougar low pressure port on top of the air conditioner compressor. The low pressure port will have a blue top.
Call your local Auto Part store.
It's on the fuel rail on the engine
possible short. have an auto electrical shop trace the problem.
and to explain a little more the brake system is electric assist, they are not fully locked i can still drive it but my rear brakes are doing all the work, how would i know if its the calipers or the accumulator motor?
Remove the tire and wheel from your 1999 Mercury Cougar. Remove the brake spring and the break caliper. The brake pads will come off. Reverse the process to install the new brake pads.
adgust the brake light switch at the brake pedel under the dash
you need to take off the master cylinder and the accumulator and replace it with a master cylinder from a non antilock vehicle like a thunderbird or cougar from about 1985 to 1988.
Are you actually looking for the woman's name?? Come on people. That's a little too personal. (By the way I am the kid who she was hitting on in the commercial...) =D
If front brakes are working properly - no frozen caliper or restricted brake lines with proper fluid flow to caliper - try check rear brake and parking adjustments to make sure they are not dragging and operating
The Low Pressure Side port is located on the line coming from the the compressor. It can be identified by the black cap marked LOW.
Cougar skin is made of cougar.
You need a torx type socket. If you use an Allen wrench...you will strip out the inside of the bolt.
The best way is to go to a junk yard and pull the disk brake assembly off of a Cougar, or a Contour/Mystique, the latter two will require you still purchase a Cougar specific E-Brake cable though. There's plenty of info on this conversion in the wheels, tires, and brakes section at the newcougar.org forums.
1995 Mercury Cougar does not have front wheel brake shoes. It has disc brakes and therefore disc brake pads. Copy & paste this link into your browser. http://www.advanceautoparts.com/english/youcan/html/ccr/ccr20021101db.html
Fuel pressure regulator.
It is on the back inside the trunk left side under the carpet.
