Dave, fitting an electrical pump is pretty well the norm for many, if you do, you can fit it near the fuel tank out of the engine bay, but make sure you fit an inline filter before it to stop crud in the tank blocking the pump (Ask Ben about that one !) you can pump the fuel through the mechanical pump and don’t need to bypass the pump so all looks stock. If you rebuild the pump make sure you take the existing pump apart and get a matching rebuild kit, the push rod can vary, some have a slot and some have a Tee, the diaphragm’s are the same so you can take the diaphragm out of the kit and only use that, but that seems like a waste of the other new parts that come in the kit. If fitting an electric pump also fit a fuel pressure regulator, the carbs are very sensitive to over pressure and will flood if too high a pressure is provided, the Facet pump will be far too high, an SU pump should be OK, but it too is borderline on the pressure.
We have a 10lb residual check valve on the K1, this is a good point from Neil the check valve keeps the lines pressurised taking up any variance in adjustment on the snail cams to lining, reducing travel to brake contact to a minimum providing that the standard springs are used on the shoes i.e. springs are neither too strong or too weak.
Hi James, you are trying to achieve braking force with less foot pressure, as I tried to explain (probably badly) before, reducing the diameter increases fluid pressure with the same foot pressure, but longer travel is the byproduct, you can calculate everything using boyles law and pedal ratio, it is very important to keep shoe adjustment as tight as possible to keep pedal travel to a minimum as you need to minimise fluid movement. Adjust shoes to lock and go back one click, you may have some touching as you turn the wheel but not drag all the way. You can bleed all corners with wheels adjusted to lock and then back off, same principle as clamping 3 wheels as Peter suggested but a little easier. This ensures no slave cylinder movement but does not eliminate air in the cylinders, that’s another explanation all together, you should get a very hard pedal with little travel, them back off each wheel one click and check every time, pedal travel will increase every time you back off one wheel.
Thanks for posting this Ben,
I had an absolutely fantastic day until the last run of the day that is, but everyone knows that story!
It was an honour and great fun to Drive Dave Lovey’s old K up the hill, and I hope he was smiling down on me, or laughing.
His racing gloves kept me company in the car as a fitting tribute to a very missed member of the AOC.
It was an absolute blast from start to finish, and the Allard supporters gave much support (mostly mick taking) but support it was indeed and thank you to Jane Warburton, Fiona Gough and Pina Brett for the usual female humour and their smiles and friendly banter was enjoyed by everyone. The cakes provided from Fiona’s oven went down a storm.Looking forward to Prescott next weekend.
