Peugeot brakes
Discussion
Yup changed the brake disks on my 405 SRI many years ago.
Its easy enough for the front just undo caliper retaining bolts and the caliper bracket, should be one screw holding the disk in place. This should have taken minutes but as most of the bolts were seized it took much sweat and swearing!
For the rear the calipers need to be wound back in, but you can buy a winding tool for a few quid from Halfords. The other thing is one of the bolt's holding the caliper is a star shaped head. Which is great as long as you have the correct size in your socket set...

I've got a 405 SRi now, dead easy to do the discs and pads...
caliper bolts come out (13mm iirc), pads out, caliper carrier bolts out (torx T40 iirc) and use an impact driver or some such to get the disc retaining screw out (philips head, or just drill it out and forget about it)
Clean up the hub with some sandpaper, put some copper anti-slip on the mating faces and put the new disc on, either rescrew it back into place or put a wheel bolt or two in to keep it on.
Clean up the runners in the caliper carrier, then bolt that back on using threadlock fluid to lock the bolts in (Torx T40 iirc)
Paint the back of the pads with anti-slip, put the new pads into the carrier and push the piston back into the caliper, if it is stiff (and your car has ABS), undo the bleed nipple a little so the fluid is expelled out the caliper (just enough) and not forced back down the brake system possibly damaging the abs modulator.
Use the new caliper mounting bolts and remount the caliper, torque them up as per haynes, check the bleed nipple is tightened, refit the wheel and lower the car to the ground.
Start the car so the abs modulator is primed, press the pedal a couple times and turn it off - pump the pedal till it stiffens up and start the car again, go for a spin and bed the brakes in by doing gentle braking for about the first 150 miles, don't sit with your foot on the brakes in traffic cos it'll cause hotspots on the disc and increase the likelyhood of warping it.
After that, you should be fine!
