My 1989 Daihatsu Charade CLS (3 Cylinder) has a low idle

The E-brake light is on because the brake is slightly on, or the fluid is low, or the brakes are failing It sounds like the fluid is getting low from normal brake wear and not a problem. Just get the front brakes cheched and replaced. Don't put any fluid in because the new brake pads which are thicker will take up the space the fluid has dropped and push the fluid back to the correct level

Your engine is shutting down at idle because of a a bad seal on the engine induction system. It is the big duct that connects to the engine air intake. Leave the car running at idle, E-Brake on, and squeeze the big black duct going from the air filter to the engine, Does the car shut off? Next check small little hoses that attache to this big air duct. Try moving them a little to see if the engine runs different.

If these are good then I would shut off engine and remove this duct. A hose clamp holds one end. A slotted srewdriver will work to remove this clamp. The other end, at the Air Filter simply unclamps by hand.

The Throttle Valve is the first thing you see in the engine, it is inside the intake just after the duct you removed between the Air Filter and Intake. Have some one open the Throttle by stepping on the gas pedal and see if it is clean around the edges. If not, use some cleanning alcohol from your medicne cabinet to clean this area. A toothbrush will get into the tight spaces. Wipe clean with paper towel. Autozones sells a special cleaner called Throttle Valve cleaner spray. Use this not Carburator Cleaner.

If it still runs bad a idle the idle valve could be dirty and now you need more tools to remove it and clean too.
