take front of the car up on axle stands,
takes the wheels off,
turn the steering wheel to get better access to the pads on one side,
undo the 12 or 13mm bolt the lower one on the calliper,
lift caliper up may be a bit tight,
remove pads may also be tight to get out,
clean up the guides in the brake pad carrier, brake cleaner and a wire brush is usefull here,
undo the brake fluid bottle cap,
push back the caliper piston with some big grips, after doing both sides you might need to take some brake fluid out to get it down to the max line,
put copper slip onto the new brake pad egdes that come into contact with the guides,
put new pads back in carrier,
lower caliper down,
tighten the 12 or 13mm bolt tight!,
turn steering wheel around to get better access on the other side and do the same to that side,
pump the brake pedal before you drive off,
check brake fluid level again,
take car out to bed in the new pads, take it easy dont go mad
hope this helps
