  1. hi i would like to see a video of the stroker sportster
    its a very impressive build and the first ive seen ever, great stuff .
    im also in the process of doing the exact same conversion on my m20

  2. Hi Patrick,
    Can you tell me what car the your brake master cylinder came from? I posted a problem I had with an MOT failure on the club website did get the brakes working but a week later the pedal had gone again. No leaks on the system so stripped out the master cylinder one of the seals very scored and hard. Ordered a replacement part assuming the master cylinder was a Sierra, it appears not to be the bolt pattern is wrong, i.e. Sierra to small. The hole centres on my master cylinder are approx. 88mm

  3. Thanks Patrick, will see if I can track one down. Would you be kid enough to measure the hole centres on the mounting plate on yours to see if they are they are the same as mine.

    Cheers Keith

    1. Hi Keith,

      I took a number of measurements and posted them here: https://www.msportster.co.uk/master-cylinder-part-numbers/

      These do seem to be difficult to identify as an orderable part though, the part number on the side only brings up the mad about thread. Ford Cortina Mk4/5 and Sierra come up on related searches. This one looks externally very similar: https://www.euspares.co.uk/parts/metelli/7722894

      Brake Master Cylinder, EAN 2212121981840

      Diameter [mm]: 22,00
      Material: Cast Iron
      Condition: New
      Designation: Brake Master Cylinder
      Manufacturer: METELLI
      EAN: 2212121981840
      Item number: 05-0099

      Searching on the metelli part number: https://www.google.com/search?q=METELLI++05-0099&client=firefox-b-d&sxsrf=ALeKk02VHWr1AKSA84fON-eEOo6AUnWU0w:1619467439477&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjO7NGr2pzwAhWJOuwKHUKwCrwQ_AUoAXoECAEQAw&biw=1440&bih=775#imgrc=5yDwzEsjDPFRPM

      You get a part with the same number on the side:

      Thanks, Patrick

  4. Cheers Patrick , It is the correct cylinder but at least a months waiting time for the order from Italy, no suppliers in the UK have this in stock and no service kits. I have emailed the European supplier to get a possible date for delivery. May be faced with changing the master cylinder I will have to wait and see. Thanks for all your help, I will let you know how I get on.

    Cheers Keith

  5. Hi Patrick,
    Well 2 plus months later finally back on the road. Metelli no longer make this cylinder, tried a Ford Sierra direct replacement with no joy. I found a company in Rochdale J & L Spares who have rebuilt the Metelli brake master cylinder for me. They bored it out and fitted a stainless steel sleeve not cheap but an excellent job.
    Cheers
    Keith

  6. Hi Patrick
    It’s Robin (Sportster Pembleton Roadster).
    I would like to do some stainless welding ( exhaust). Can you tell me what equipment you used please. I have an inverter DC welder, it’s the gas and torch thingy I will need to get.
    Cheers Robin
