Power brake boosters work off vaccum. If there is a slight leak in one of the vaccum lines engine speed would have to be increased to make up the difference.Hence the reason they seem to work fine above idle.
ABS brakes should have no effect on engine idle, but a bad power brake vacuum booster would have an effect on engine idle.

Power brakes use engine vacuum to get their power. If the engine is out of tune, the loss of vacuum will cause it to run rough. Try changing the spark plugs.
A car may stall at idle speed when the brakes are applied due to increased load on the engine, which can happen if the idle speed is not properly adjusted. Additionally, a vacuum leak, faulty idle air control valve, or issues with the fuel system can disrupt the air-fuel mixture, causing the engine to struggle under the added strain. If the engine is not receiving enough power to maintain idle, it may shut off. Regular maintenance and diagnostics can help identify and resolve the underlying issues.
You need to check the idle control valve, and the air filter.
Allow the engine to idle for one minute, and press the brakes. Keep the engine running and absorb the temperature of the fluid.
Your car may fluctuate in idle while applying the brakes due to a problem in the computer. Everything in cars nowadays is regulated by the ECM(Electronic Control Module). A few simple diagnostics tests done by a certified tech can tell you what exactly the problem is. You may also have a bad power brake vacuum booster, this would effect the engine idle when the brakes are applied.
If your 1995 Eclipse dies when you push in the clutch, it could be due to a few issues. One common reason is a problem with the idle air control valve (IACV), which regulates airflow at idle; if it's malfunctioning, the engine may stall when the load from the drivetrain is removed. Another possibility is a vacuum leak or fuel delivery issue, which can affect engine performance when the engine transitions to idle. Lastly, a faulty sensor, such as the crankshaft position sensor, could also cause stalling under these conditions.
Check for a vacuum leak around the throtle body and intake manifold.
Engine running above idle around 13.8v to 14.5v
The idle control valve works by regulating the idle speed of the engine. The idle speed of the engine is usually controlled by the engine of the computer.
