Turning does not stop 205

Hello, I have a problem with the brakes of a Peugeot 205 Diesel myth 1.8 of 1995, when turning in a curve closed to the left and when braking it is in the same curve or then, the pedal sa goes to the bottom and does not stop, I mean that the first floor that I fight to the pedal is empty.
If someone knows a possible cause, I would appreciate it

It is only when turning or in line also occurs, because what you say is a bomb problem but that only happens in crows unravels me.

Hello, your problem is likely to be generated by the bufa valero that when damage gives that braking effect

Check if you have any slack in the bearing of the front wheels. It can be that if they are wrong when the disc is based on the pills and the bull of the brake clamp leaves you leaving you like this without a brake pedal

Thank you all it was a slack caused by bearing of the
Ivacoma bushing gave it fully hehe
