I tried to search for this, but there's a million posts on brakes but I didn't see any that discussed this questions specifically... Went to rotate tires for the season but they were welded on but good, so let the dealer beat them off and they can check the brakes while they're at it. Turns out that despite the annual dealer rear brake pm lube job the rears need work (about 50k miles since last replacement). Now that the wheels can be taken off the car I don't mind doing the brake work myself and have started gathering part supplies. This time around I am considering replacing the caliper guide pins and boots thinking that since the V's have a predilection for sticking in the back end causing wear, they might as well get replaced. My question for those who have done their own brakes - do you replace the caliper pin hardware as point of fact (only adds about $20 to parts), or do you just clean things up and put the old sliders back in? I'd rather have them on hand in case I need them, and if I'm going to have them on hand I might as well replace them anyway. Thanks.
