This caliper seal rebuild kit from Girodisc is the perfect option for replacing worn out or cooked dust boots and piston seals on your Mustang. This kit fits the 40/44mm 4-piston Brembo brake calipers found on the 11-14 GT w/ Track Package, Boss 302, and the 2007-2012 GT500.
One kit is enough to rebuild one caliper.
