Does AC affect braking?
TOM: There are two possible ways the AC could affect the brakes in small ways. One is via the idle air control (IAC). If you’re stopped at a light with your foot planted on the brake pedal, you might feel the pedal drop a tiny bit when the compressor cycles off and increases the engine vacuum slightly.
Why are my brakes not holding pressure?
This can be due to a number of problems: a leak in a brake line, a loss of pressure within the master cylinder itself due to a failed seal, or air being introduced into the braking system. Your first reaction to encountering spongy brakes should be to rapidly pump the brake pedal with your foot.
What does it mean when your brakes lose pressure?
Getting no pressure means you are experiencing soft brakes meaning a brake pedal doesn’t offer the reassuring pressure that it normally does and it can be very alarming, especially when you are driving.
