The brake pedal on the car is quite long making it difficult to heel and toe while racing. We've got 310mm Megane Brembos, Hi-Tech discs and CarboTech XP8 pads. Copper piping throughout as well.Is there anything we can do to make the "bite point" higher up? Don't have a huge deal of confidence in the brakes at the moment. ________________________________________ Rallye Race Car |

I changed the standard master cylinder for a bigger one, around 25mm. Made the world of difference to the pedal travel/feel with my AP calipers. |

Do you have any details on which one you got and the work involved to fit it? ________________________________________ Rallye Race Car |

trying to remember where they came from, I know Citroen sport have used one, there's some on the PSA vans but I don't know if they fit directly or not, see what Marting comes back with ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I couldn't find a lot of info when I was looking for a bigger one. Took HOURS of trawling foreign parts sites and stuff to try and find pictures.As it was, i literally had to go by a picture and hope for the best. I managed to get it right though! Its off a VW Transporter of all things! The only difference when it comes to fitting, is that the ports are on the opposite side of the cylinder to the standard one. So i just fitted a couple of little extenders to reach my current pipes. I think i also had to warm the reservoir and mould that out of the way of one of the fittings, but it was just a hot air gun and a push that sorted it. That's just a problem caused by the ports coming out underneath the reservoir rather than the standard position. Fits perfectly onto the servo, exactly the same fitment as the standard on in that respect. |

Thanks very much! No idea how you found that :pSomething like this should be ok? http://www.vwheritage.com/vw_spares_Master-Cylinder-T4-19603-No-ABS-ITT-Calipers-7D0611019A_act_shop.product_pID_143248615.htm ________________________________________ Rallye Race Car |

Il have a look and see if ive got a part number on mine in a minute. As said though, mine only has 2 ports, like the standard 306 one only has 2 ports also. Saves having to block any up.And whaen I said it took HOURS of searching, that pretty much meant DAYS! The main concern apart from fitting to the servo was the reservoir mounting holes. Where the fluid goes in. A lot of them have a bigger gap there |

excellent thread, I've always thought my 330s gave me a lot more pedal travel, the things makes me go dizzy it stops so well but I've always thought I seemed to be have to press the pedal pretty hard ________________________________________ andrew315rawson@live.co.ukMoonstone phase 7 gti6 My Project thread: http://www.306gti6.com/forum/showthread.php?id=119992&page=1 |

I'll get one of those MCs and do a small thread on how to fit it, just for future reference.________________________________________ Rallye Race Car |

This was what I mean by the brake pipes. I had to get this ready pretty sharpish, otherwise I would have put a full length of new pipe in. You can see how close the unions are to the reservoir. But as I said before, with a bit of heat they will clear fine. Ive now moved to a bias pedal box, so im hoping that will end up with a good pedal like this bigger cylinder did before! |

Did it need to have the tie wrap around it or is that just a precaution?________________________________________ andrew315rawson@live.co.ukMoonstone phase 7 gti6 My Project thread: http://www.306gti6.com/forum/showthread.php?id=119992&page=1 |

Precautionary. The stuff I do occasionally has unbelievably bouncy and rough tracks in places with hard suspension. Didn't want the chance of it riding up in any way. Even though the pin that goes through should hold it in place regardless. |
