electric

Hello I need help. I have a Hyundai Lantra of the year 94 is a 1.5I GLS, the problem is that when the brake is placed the car accelerates and sometimes it stops or when the lights do it too. I don't know what it can be. thank you

It is not an electrical system, it is the master that has broken the diaphragm internally; Cap the hose that goes to the master and test.

Can you tell me that it is the master? Why the truth is that I understand little. many thanks for everything

The master is the servo brake, it is an air membrane that is behind the brake pump and has a hose that goes towards the multiple of admission, check it as Mac 2 Hojo tells you that the brake will be very hard so stops before testing and let us know, I spend a very rare case very similar to yours but the drama was the land of the fuel pump. But first the servo and the alternator load.

Thank you very much I thank you
