It RT>seems that the front right disc rotor becomes warped and will create a RT>shimmy with hard braking. The warpage is slight and can be corrected RT>with machining... for a while. I've had the rotors turned several times RT>for nothing else but this. I've replaced both rotors twice. Mr. RT>Goodwrench's only suggestion is that tire changers are over tightening RT>lug nuts. I disagree... I've insisted that they used only hand wrenches RT>and be particularly attentive to torque. The problem always comes RT>back after just about two or three thousand miles. Any suggestions??? I have one suggestion. Be sure the front calipers are lubricated with the special grease designed for that purpose. Most of the time when front disk brake pads are prematurely worn AND when rotors are warped it is because of the caliper NOT releasing - thus keeping the pad is contact with the rotor. This causes excessive wear of the pad AND excessive rotor heating - thus warping. Normally in this case ONLY one pad will be worn much more than the othr pad for that caliper. RT>Oh yeah... most of the mileage is pulling a 5x8 Wells Cargo utility RT>trailer, about 1500 lbs gw. RT>Second problem. Really a question... the disc pad bracket seems to be RT>loose on the same front right wheel... sometimes.

After a couple of stops, it corrects itself and RT>is quite, even on panic stops. Braking ability does not seem to be RT>affected. Some GM brakes have a metal spring/clip that causes the pads to stays aligned - if this is missing funny noises can result. Saw that on my Kid's Chevy Cavalier. RT>The pads and rotors are less than 10% used... rotors aren't even scored RT>yet (but shimmying away, nonetheless). RT>First... is this a dangerous situation? Then, what causes it?? Bad RT>pad?

Well, for a car that looks as outrageous and aggressive as the Prowler, you would expect times right around 5 seconds. There are plenty of under 7 cars with automatic transmissions, the new Jaguar, the C5, all of the American pony cars, i'm not sure how fast the luxury Benz's are, but i know a Lexus GS400 will do 0-60 in about 6 seconds. For a two seat roadster, seven seconds is a looooooooooooooooooooong time. -Lates --- Telegard v3.09.g1/mL * Origin: The Rapid Eye - 913-393-4104 - Olathe,KS (1:280/183) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: F2H00003 Date: 02/11/98 From: DEVIN DIMITRI Time: 03:19pm \/To: MARC GERGES (Read 0 times) Subj: Re: 225 hp Neon?

That gives foot pounds per minute. Then, 33000 foot pounds of work per minute is a HP. This is the Indicated Horsepower. -Lates --- Telegard v3.09.g1/mL * Origin: The Rapid Eye - 913-393-4104 - Olathe,KS (1:280/183) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: F2H00004 Date: 02/11/98 From: DEVIN DIMITRI Time: 03:24pm \/To: ALAN MORRISON (Read 0 times) Subj: Re: Active Handling AM> Caddy is known for ride and amenities, not handling.

Rear Only braking is very scary when you loose the fronts. --- GEcho 1.20/Pro * Origin: Jim's East County BBS! El Cajon, CA.

I'll check into it though, -> it is getting fairly old. Noticed something interesting about one of my Subaru's some time back. To Improve Cold engine operability the Temperature sensor for the Engine control computer is located on the Radiator side of the Thermostat. That leaves it Enriched fuel mode until the Thermostat opens. Very slick trick. And incidentally for you Hot Rodders out there you have limited control of Fuel/Air ratios by playing with that sensor input to the computer. But fiddling with the O2 sensor is far better. Withy it you can get a very wide range of Fuel/Air ratios. Lean for Cruising and Rich for Performance when you need it. :-) Of course boys and girls don't try this in California!! :-) You might get nailed by one of the new Infa-Red Road side Pollution monitoring machines. --- GEcho 1.20/Pro * Origin: Jim's East County BBS!

The bottom ring is called the oil Control ring. It is specialy shaped and designed to Scrape off the OIl thrown up on the cylinder walls under the piston so it will not overload and pass by the Compression ring into the Combustion chamber and be burned. And is sufficient quantities, Usually because of loose rod bearings throwing larger amounts of oil on the cylinder walls, causing that oil to pass by the rings and Foul or oil coat the spark plugs. --- GEcho 1.20/Pro * Origin: Jim's East County BBS!
