Normally Brakes are working normally and fine. However when AC is turned on after a few minutes as the cooling starts, brakes start becoming less and less effective.
First you can feel brakes are becoming less and less effective and after a while the brake pedal becomes hard and hardly any braking is there. It is a nightmare driving and I have to immediately come to lower gear and apply hand brake and press the hardened brake pedal to get braking.

Hello,

Which car? how long you facing the issue

> It seems that engine belt has loose the tension and due to further load of ac compressor its pulling down and thus leading to lesser effectiveness in braking

> Possibly can also be an issue with Brake booster

> Lastly there could also be vacuum loss, lesser brake fluid which is causing an issue in braking

Suggest to get car inspected at Authorized workshop on immediate basis, as this can be risky to drive in.
