right, makes more sence now :thumbs: | |

The reductions are probably minimal and the size of the pads are significantly larger than the standard solid disk brake setup on a Corsa. | |

i now understand that ed, but if you reduce the amount of aplification how are the brakes more effective? | |

What you are doing by using hydraulics is amplifying the force by using a large master cylinder which displaces a large ammount of fluid into a small slave cylinder in the calipers. If you increase the size of the slave cylinder then you reduce the ammount of amplification you achieve. | |

XE brakes use a larger caliper and have more ventilation, which gives the difference. | |

Type of disc will make next to no difference anyway TBH, the pad will, but the disc is generally better if it's plain, not drilled and/or grooved, in my experience. | |

quote: Yep. Remember that the larger surface area of the piston will exert a larger force on the pad too, regardless of the size of the master cylinder, due to the volume of fluid. | |

like i said im not arguing im genuinly interested...like i told ed via u2u :) | |

seems like this will turn out to be an extension of ed & hamish's argument then... personally i dont have a clue about the brakes i just didnt want to use a 2ltr setup because i wanted something different | |

ok but that doesnt explain the difference in performance betwween the gsi setup and the 2 ltr setup. Or are the pads bigger on the xe setup? | |

pad contact area. | |

greater surface area ie pads on disc | |

Right following of from a discussion in Dan295 project thread. Im now confused about brakes. |
