Brake Caliper Treatment.
Corrosion in the brakes is best prevented. Rust buildup can seize the sliding movement of the caliper - resulting in pad wear and friction when driving. Corrosion also makes maintenance difficult.
I prepared the calipers and discs as follows: Disassemble, clamp parts and totally remove all corrosion with electric drill and various rotating wire brushes (wear goggles and mask).
Heat resistant caliper paint can be applied directly to the bare metal, though I also primed with brown rust-eater paint.
The disc hub and disc edge should be cleaned. Paint the hub, and copper grease the disc edge (the grease vapourises leaving the copper, which reduces corrosion). If not treated, the disc edge can reduce in diameter and expose the brake pads, and also cause disc imbalance.
Top coat in black applied after rust paint dry in 24 hours.
When replacing wheel bolts or nuts, apply copper grease to the shoulders (mating surfaces). This makes for smooth turning and accurate torque setting. Use a torqe wrench.
