How much fluid should it take to change, any special method to changing fluid? pumps or special equipment needed, anything?

Thanks
See this post and others around it: https://www.jaguarforums.com/forum/f...0/#post1865998
No special method or tools needed, these are fairly old-fashioned brakes that can be bled the old fashioned way, so either gravity bleed or pump using the brake pedal or use a powered pump like most shops do.

DOT 4 SL.6 is specified and perfect for the application. My 3 year service is coming up in July so the fluid will be changed then. Since I'm not going to be cracking open the brake lines to do the rotor swap, there's no need to do anything more than check the fluid level after the project is done.

That matches my current expectations. I do need to get a 9mm hex key, per another thread, but that's hardly a difficult thing. Local auto parts? Amazon? Snap-On? There's one out there with my name on it.

All of those plus NAPA auto parts, and ACE Hardware carries Craftman tools if you don't have a nearby Sears.

The internet has one on the way. Not sure whether the pads or the tool will arrive first, but I expect that both will be in hand before the rotors themselves.

Paul thinks he will ship tomorrow or early next week. Don't know if they're coming by slow boat of air freight.

Porterfields are in hand (on shelf, to be accurate). I needed a few bits from Snap-On, so added the (paid too much for) the 9mm driver, but it'll be matchy-matchy with most of my other hand tools.

Calling back to some previous posts I saw: Front pads are massive, and came in a plain box, held together by a rubber band.

Don't worry, the 9 mm driver is the only "special" tool you will need.
Just one tip - do all the caliper bolts up nice and tight so use a 1/2" socket driver not a piddly 3/8".

I don't usually resort to 1/2" drive until I get to lug nuts or major pieces. I've gone to 3/4" only for really serious ****. What's the torque spec?

Mine didn’t even have a rubber band.

Torque specs:

Caliper bracket (wot bolts to the hub): front and rear both 115 Nm / 85 ft/lb.
Front caliper bolts (the slide pins, wot you need the 9 mm driver for): 58 Nm / 43 ft/lb.
Rear caliper bolts (15 mm IIRC but could be 12, 13 or 14 mm): 35 Nm / 26 ft/lb.
