on my last car a 987 boxster I replaced the front pads at 19000 miles the discs were ok this was after the car was 4 years old( I was also told in the service that I needed discs and pads so I replaced them myself(pads only) ) ,I also replaced rear pads a year later. on the six year service car was ok and on 8 year service car was ok .before the 10 year service I ground the lips off all the discs and replaced the front and rear pads(the discs were well within the thickness limit),the car had done 37000 miles,bought the pads from gmf motor factors for about £100 ,when I took the car for the 10 year service the opc asked me who had resurfaced the discs as they had done a good job,better than what the could have done with their resurface machine(all I done was took the discs off the car used a angle grinder and then dressed the surface of the discs with a file and some emery tape I also cleaned all the disc vent holes out with a drill ) if you can do the work yourself it will work out a lot cheaper as the prices they charge for replacement is high,this is how the opc makes a lot of money as people will just pay to get them done , (as I work in engine manufacturing plant on electrical /mech systems it was easy to do) my 981 is due for a service next month and has covered 12000 miles,discs and pads are all ok , so it will be interesting to see what opc has to say. I did price 981 pads front and rear from euro car parts and genuine ones are £130 a set(car is still under Porsche warranty )
edited to add - a few weeks ago I bought discs ,pads rear shoes(all mintex) and 4 brake flex pipes for my xr3i project car for under £85!
