Burnishing Linings & Rotors (Disc Brakes)

After the brake linings are replaced and/or the rotors refinished, the new braking surface should be broken in, or "burnished". To do this, make 20 stops from 30 mph using medium to firm brake pedal pressure. During this procedure, use care to avoid overheating the brakes.
