The Wilwood 300-14504 is a set of four steel retaining clips for the pad retaining pins on Wilwood DP6, D8, TX6R and Aero brake calipers. Those clips hold the pins in place, which keeps the pads seated under heavy braking. On a track car that sees repeated heat cycles, a loose or fatigued clip is a cheap failure to prevent. Replacing it with a matched Wilwood part costs far less than rebuilding a caliper or chasing a rattling pad mid-session.
Enthusiasts searching for Wilwood DP6 pad pin clips, D8 caliper retainer clips, TX6R pad retaining clip replacement, or Aero caliper pin clip sets are looking for this part. Confirm your caliper family before ordering. The manufacturer lists the 300-17719 as a DP6 kit that includes pins as well as clips, so DP6 owners who need pins should compare the two. For a pad change, the retaining clip is popped off the pin, the pin slides out, and the pads come out for service. Wilwood's assembly sheets for its kits stress that installation should be done by people experienced with disc brake systems, so take the job seriously.
The manufacturer lists this clip kit for Wilwood DP6, D8, TX6R and Aero calipers. Confirm your caliper model against the manufacturer's listing before ordering.
The manufacturer describes the 300-17719 as a DP6 kit that includes both retaining pins and clips. The 300-14504 is listed as a set of four retaining clips for the D8, DP6, TX6R and Aero group. If you need new pins as well, check the contents of each kit before buying.
This is a pad-change job rather than a full brake overhaul, so basic hand tools are usually enough. Remove the pads, pop the clip off the retaining pin, slide the pin out, and install the new clip on the pin. Owners on user forums report that retaining pins can back out when a clip is missing or was never reinstalled after a pad change, so check the clip every time the pads come out. Wilwood's install guidance for its kits calls for experienced installers, and the manufacturer recommends taking photos before disassembly so the parts go back in the right order.
