If the pads are very worn the pistons may have pushed further out of their
calipers than normal, so after removing the pads, [1] I generally use a
g-cramp (more often a bit of wood) to press them back in again, but watch
the master cylinder fluid level. If you have another bit of wood that's a
tad wider than the pads you can use this for the calipers/pistons to press
against, and work the brake pedal so that the piston leaves a mark on the
wood, and can give an indication if the pistons are sticking on one side or
another .. but it is only an approximation ..
Clean all the accumulated crap from the calipers and 'slidey' bits where the
pads reside, I use a handmade scraper and a wire brush. Then use Copaslip
(I think that's what it's called, the labels worn off years ago) grease,
which is a high temperature anti-seize grease, pasting a very thin smear on
all mating / sliding surfaces of the pads and calipers. Don't get any
grease at all on the pad friction material, or even within sniffing distance
if possible ..
Brute force shouldn't really (though this _is_ a Landrover) be needed unless
there's lots of corrosion / crud to get in the way, and usually involves the
smallest item, the split pins ...
Have fun .. they're easier to do than S3 brakes ...
[1] Remove ssmall split pin behind the caliper, then pull the pad
location/retaining pins, while holding the anti-rattle springs. Pads should
now pull out easily .. Replacement, as the saying goes, is a reversal of the
removals procedure, but the springs can be fiddly to hold ... It is _much_
easier if you have all new pins/split pins/springs to work with. They come
in kits and cost bugger all ..
