2004 Charade 1.0 El - Brake upgrade????

Forum: 

Hi - We've just put the above car on the road for a daughter who's just passed her test. Everything's OK except the brakes seem nowhere near good enough for the gem of an engine. I've put new discs n pads on front, rear adjusters are good and changed fluid. Car does stop but isn't exactly confidence inspiring.

Are there any bolt on upgrades for rotor size / callipers from anything else in catalogue that would improve things???

Help!

Regards,

JIM
