I've even soldered an old tyre valve into the bottom of an empty carb cleaner aerosol so i can fill it with the mix and squirt it out after pressurising it with the compressor. It's even shifted downpipe nuts that have been rusting onto a turbo for 20+ years without bother! As for the bleeding, get yourself a Gunsons Ezi-Bleed, it even comes with the right cap to go straight onto the master cylinder! Excluding the time to remove the wheels, it took me about 20 minutes to completely replace the brake fluid/bleed mine. The sequence for yours should be the same as mine : Left Rear Right Rear Left Front Right Front Pressure bleeding it overcomes any problems with sticky valves in the ABS modulator and generally makes life quicker and easier all round.

Hi Dave, my brother was telling me of the good old days when he had this old pressure bleeder that connected to a spare wheel and used the air pressure in there to pressurise the system, it must have been the Gunson Ezi-Bleed or something very much like it. Less than half the price of the Seeley as well!

That's the kiddy Myron and this appears to be the best price (inc P&P) on fleabay at the moment :
https://www.ebay.co.uk/itm/GUNSON-TO...EAAOSwAaJaKR3C I pushed my spare up to 40spi before starting each leg, seemed to work better although they recommend about 20psi but it soon drops off as you use it.

As long as you seal it to prevent the acetone evaporating off, yes. Don't forget to give it a good shake before decanting it for use to make sure it's still mixed as it has a tendency to separate when stored for some reason.

Great things the Gusons ezibleed. I have had one for years. I used to use the spare wheel but now I have an air compressor I just turn the regulator right down and use my tyre inflator with the trigger tied back.

Okay, bleeding appeared to go well, passed about 2 litres through in total, looking clear, no bubbles. Pressing brake down with engine off gives 1" travel and then hard. However turn the engine on and it's another story, travel about 3" with a squelching sound like pumping balloon, release the pedal and a 'click' from the area round the master cylinder. I can drive it ok, brakes seem ok. I've bled the two nipples round the master cylinder as well, no evidence of air. If it's air I'll give it another go but I've done it twice already!
