CSR brake fluid change - what fluid and how many Litres?

[finmac]

Car is mostly road but some track thrown in. Recommended fluid to buy? and how many litres will I need please? 

[Jonathan Kay]

DOT 4. Factory recommendation was Comma but anything reputable should be OK

I don't know the volume. On other Sevens it's said to be 500 or 750 mL.

Finmac, if you are going to replace the brake fluid after several years it might be prudent to remove the calipers and drain all the fluid out, thus removing any accumulated water from the bottom of the piston chamber, as if you just replace the fluid in the master cylinder reservoir, and flush it through to the wheel assemblies all that happens is the top of the wheel cylinders have fresh fluid, however the old fluid remains in the caliper, fluid feed and bleed points are often close together at the top of the caliper, flushing old, potentially water contaminated fluid would also remove the potential for corrosion to form in the cylinder bores, causing other problems, binding brakes, being one.
