The Morris Minor master cylinder will not do, the bore is too small.
The standard bore on my M type and K1 with phase 1 brakes was 1″. When I fitted phase 2 front brakes (which P1’s have) I had more than the usual difficulty in getting a good “pedal”.
It didn’t have the usual mc but it was 1″ bore. I chatted with Paul at Power Track and eventually decided on a 1.25″ bore mc. This provides a bigger fluid displacement and has provided a much better “pedal”. The piston stroke remains the same but the bracket bolt spacing needed minor modification. I also fitted a remote fluid reservoir which many of the original set ups didn’t have. They have a combined reservoir which is quite small and needs constant and tedious replenishment when bleeding (which can be another problematic area that needs particular understanding for Allards).
There are several places you can get Lockheed brake parts from. I tend to use Power Track: http://www.powerrackbrakes.co.uk and Past Parts : http://www.pastparts.co.uk .
Rick Newman and I are in the process of setting up a fully itemised Technical section for the website. The plan is to arrange a drop down menu from a Technical menu heading that will list the various Allard models and their component parts all under separate headings.
These will then be populated with technical information and advice. There will then be a separate menu heading for Suppliers which will be similarly set up. We will be welcoming information and advice from members which will need vetting before posting. We will be seeking the help of our own members as well as commercial suppliers for this.
It will be a big task so please bear with us. We need to configure and set this up with the webmaster and are advised that he may not be able to organise it for a couple of months.
In the meantime I will try to scan the illustrated 25 page Lockheed Service Manual. It covers the Allards fitted with phase 1 brakes. I will then do the same for another smaller manual I have for the phase 2 brakes.
Bear with me please.
