Stainless steel brake sleeves replace the rubber caliper retaining pin insulators on 1987-1993 V-8 Mustangs. They eliminate caliper deflection and rotor/pad distortion, and extend pad life up to 50%. Better control of the caliper means more stopping power and fewer warped rotors. These parts will pay for themselves by your next brake job. You can make the switch with basic hand tools and without disconnecting your brake lines. 1987, 1988, 1989, 1990, 1991, 1992, 1993 Mustang GT 555-6100$46.95 www.realspeedauto.com Ph.631-563-7325 All parts listed are for the Ford Mustang unless otherwise noted.
