Brake bleed order
I want to do a complete flush (brakes & clutch). I was under the impression that you start at the item furthest from the reservoir first
(passenger rear brake for example) and work towards it. However I just looked in a Haynes manual and it said start with drivers front, passenger
front, passenger rear (live axle, no driver rear bleed).
Which is it? Does it make a difference?
Regards,
Dave

Unless your changing to a Silicone based sythetic fluid it is perhaps not a good idea to completely empty the system it could open a can of
worms when you bleed the system
If you have a front rear split hydraulic system the order of bleeding doesn’t really matter
I would suggest you adopt the following approach.
Use a Turkey baster (about £2.00 from Sainsburys) or large syringe to empty most of the fluid from mastercylinder.
Push the brake pads back to the fully retracted position, then use the Turkey baster to get as much fluid out as possible resevoir.
Fill the reservoir and bleed one circuit at a time, get an assistant to hold the pedal down when you tighten the nipples.
Even if you are using a pressure bleeder the pedal should be pumped a couple times at the start of bleeding each circuit. bleeding each circuit,
you can do this with the pressure bleeder attached.
If old fashioned manual bleeding the pedal should be pumped slowly -- especial slow on the up stroke of the pedal.

And you can re-use the turkey baster for inseminating broody girlfriends who wish to father your children but do do do wash it out first otherwise
you'll end up with summat like this:

I guess if you're flushing the system rather than bleeding then you'd push all the black crap out through the nearest nipple first as not
to drag it through the entire system. Bleeding is usually done working furthest to nearest though.
