The Billet 4 is Hi Spec’s most popular four piston caliper. The body and pistons are machined from 6082 T6 billet aluminium, with external dust boots to keep dirt out, so it needs very little looking after on a road car. This kit uses the radial mount version of the caliper.
A bolt-on front big brake conversion for the Ford Escort Mk1 and Mk2 RS models, Capri Mk1 to Mk3 and Cortina Mk2, built around 280mm x 26mm one piece discs and the Billet 4 Radial caliper. Minimum wheel size is 15 inch, and as always check your own wheels clear the caliper before ordering.
