|  Brake bias valve Can I ask if everyone who has a brake proportioning valve from their donor has fitted it to their Roadster? If so, where, and at what angle & which way round have you fitted it? Also does anyone have the length and part nos of the flexy brake pipes they have used front & rear? Thanks, Dennis. |

|   The prototype with disc front/drum rear brakes didn't need one.  If you fit it it'll need to be fitted at the same angle as it is in the Sierra, which I can't remember.   8 degrees? could be   Cheers Chris  |

|   leave it off and when your ready to put it on the road get a friendly mot station to check the brake bias on theyre rollers they usually do a calculation to check its ok for mots if you find the bias is wrong you can change the rear cylinders for ones of a different bore or fit a valve but it really is better without one Ray  |

|   Interestingly enough, the Tiger Avon actually has a bracket ready to receive the Sierra valve, whereas MK Indy's seem to manage without it. |
