I know there is a bleed sequence for ABS cars, do I need a pressure bleeder (Seeley type?) or can I do it the old fashioned way?

The "WMP" (Weapon of Mass Penetration) aka acetone/synth ATF works every time Myron!

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.
