Rear Brakes

All, My disco 2 with about 110k miles on clock has been making strange noises from the rear from time to time recently. Having just checked round I've just spotted there is no pad on the outside / off side and the disc face is nothing like as smooth as those on the other wheels.

I clearly need to replace the brake pads on that wheel, do I need to do the disc too? Also if I'm doing one side should I do the other side too? Will any electrical reset be necessary or is it just like the old days of ease calipers back and watch for fluid overflow?

Thanks in advance for your thoughts.

Richard.

Whatever you do on brakes you do in pairs, so both sides of the axel get the same treatment.

As above and you prob have a seized caliper that side, needs investigating

Yeah forgot to say you probably want pads/discs and then a sliding pin service kit with appropriate rubber friendly grease (I.e not copper slip or GP grease).

Thanks for that, will get the bits ordered!
