307 not braking when air conditioning is on ???

friends, I noticed a problem ... we parked the car at night the next day when we started the car when we left the park, automatic air conditioning is activated from the heat ... ok until now but when doing the maneuvering back and forth from the park, the brakes are as hard as the bicycle brake. I can only stop until the end, but when I hold my foot down the brake pedal, when I turn off the air conditioner, the brake pedal goes down 1.2 cm further and the brake returns to normal ... also this happens only at the first start .. it is not such a problem while driving in normal traffic ...
What could be the reason for this .... I don't think it's normal, there is a problem, what do you think could be?

I do not know if the air conditioner will affect the brake, they say, do not leave the air conditioner on while starting or stopping the car.

kaan_ very interesting I wondered. I wonder, the air conditioner uses electricity, so the brakes are not powered because the electronics operate with electricity.

Hodja, is there a problem I heard for the first time?

I was nervous too, I realized for the last few days ... when I was traveling in normal traffic from God, there was nothing like this ... If I don't have a meeting with the service, they will say that they will bring it, but :)))
By the way, when I connect it to the device, there is no problem or malfunction.

Well, let's look at the interesting braking system. One or two things are important. I always say 1 wheels and 2 brakes. If one doesn't work, you will work on the other side.

I think the same situation exists in my vehicle. However, I thought that it might be because of the air conditioning right now. As you said, it barely holds and heals instantly. In fact, I was driving to another car, even if it was small once, when I left the parking lot.

In the first operation, if the charger is not fully operational and cannot produce the required current, it may not be able to supply the necessary power to the other electronic components.

the same thing happens in me, occasionally when I get hungry, it hardens the pedal

This seems like a chronic problem, as if the battery is new ... I do not think there will be a problem with the charging dynamo, the master checks every time I go ... I wonder if my stuff is inadequate ... I did not understand.

If the brake is too hard, there is a vacuum leak. If the pedal becomes too soft, the master cylinder malfunction.

I think I think that it is slowing down when the air conditioner turns on when the air conditioner is turned on.

the brake gets very hard, but when you start moving, everything returns to normal as you say, there is a possibility of vacuum leakage.

Good evening, as I have a similar problem with my 2003 307 SW 1.6 car, I wonder if there is a solution to this situation?

friends not holding the brakes has nothing to do with electrical leakage ... when the air conditioner is on, the brake can hold a little less because it is connected to the v-belt and rotates with the engine when the air conditioner is on .. it does not affect when it is idle, but it may theoretically also be difficult to stop due to the load when it is in gear.

Peugeot 307 xt premium auto I am a transmission user and I noticed that my brakes are not holding when the air conditioner is on and backing up for about six months. And the brakemen said that westing house was faulty and passed it off. I thought I'd look inside and when I looked, I realized that the hole is very small and the air passage is very limited. When I heated and pierced the thin screwdriver, the valve that provided air inlet opened, and when I assembled the car and tested the brake, I realized that my problem with the brakes was over. /span>

I'm not talking about the check valve at the Westing house inlet, by the way, I solved the problem by increasing the air intake by expanding the hole of the long valve-like protrusion on the intake manifold, which is connected to the hose.
