Brake pads for Mark Williams front & rear 4 piston calipers. May fit some Wilwood, JFZ, & Airheart Calipers. Can be adapted to fit Lamb 11.5" Brakes. Replaces Ferodo FRP505A / FRP505B and MW-81130. Sold as a single pad. MAINTENANCE REQUIREMENTS: Periodic check of rotor for excessive heat or run-out. Check torque on caliper mounting bolts. Periodic check of brake pads. Pads should be changed once the friction material is down to approx. .200. As the pads wear more of the pis tons are out of the bores in the calipers which can possibly lead to the pistons binding or not retracting. When pads are changed the entire caliper should be thoroughly cleaned, especially the pistons before they pushed back into the bores. |
