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.
A bolt-on front big brake conversion for the Ford Escort Mk3 and Mk4, RS models included, built around 283mm x 24mm one piece discs and the Billet 4 caliper. Minimum wheel size is 15 inch, and as always check your own wheels clear the caliper before ordering.
