My new parts arrived today. The middle section of exhaust, new master cylinders, new spindle and turbine for the water pump, plus the seals and a couple of bleed nipples.

So on with the water pump first – the two spindles and turbine side by side. The new one is a lot better and is already attached to the spindle 😀

Placed everything back on the engine and filled with coolant. Seems to be holding very well so far, not a spec of water coming out. Job Done 😀

The exhaust went on OK, I placed the rear on axle stands and bolted it on. It is not the best fit for an exhaust but it is solid and is not knocking. I thing the silencer box needs to be a little wider to fit nicely. Another Job Done 😀

But here is the Issue I have now – I put in the new Brake Master Cylinder – I bled each wheel in turn about 4 or 5 times. The pedal is slack, no resistance at all,as if there was a leak. I have checked and no leak – even the old master cylinder put the brakes on although it leaked form the front push rod.
But then the pedal goes solid – no movement at all. Then it releases and is spongy again with zero pressure i.e. zero brakes. I am using DOT 4 liquid. All the brake lines are new and as I said it worked perfectly the other day albeit the master cylinder leaked. So are there different types of master cylinder, could this be a wrong ‘un??
