Default Highway Idle

Interesting comment. Thats the way I understand it to work.
I think threre is a switch on my abs master cylinder that disconnects TCC lockup.
My 96 bonne hit the brake and the idle drops to 1,000 or so.
The 90 SSE cruises 1500 rpm on deceleration around town, on the high way.
Once I went down a spiral ramp from a parking garage while cold and dropped it into
neutral on the way down and the rpm went up to 1500.
I had to put performance brakes on the car because it was eating pads once a year.

Had the Performance Friction Carbon Metallics on our '90 briefly. Pedal pressure when way up and was never certain it would stop. Went to the second level Raybestos pads and everything went back to normal. Our pads last about 30,000 miles.

Raybestos are good pads also.
I have them on my 96 form Carquest.
Both cars seem to stop the same.
