			==Hydraulic==

			Most motorcycle brakes banjo bolts are 10mm x 1.25 pitch. Brembo brakes are 1.0 pitch.

			Typical bleed nipples will be 8mm x 1.25 pitch.

			==Fixing==

			Bolts used to fix calipers to the bike should be high quality. Look for 8.8, 10.9 or 12.9 grade bolts. Avoid stainless steel unless you know what you're doing, since stainless typically does not have the required tensile strength.

=Brake Caliper Pistons=

When you squeeze the brake lever, hydraulic fluid is pushed from the master cylinder, though the brake hose, increasing pressure in the brake caliper. This pressure forces the brake piston outward, pushing the brake pad against the brake disc.

Because of their relatively inaccessible location and exposure to water, salt, and corrosive brake dust, brake caliper pistons are highly susceptible to corrosion.

==Stainless Steel==
The most common material for corrosion-resistant aftermarket caliper pistons is stainless steel.

==Phenolic Plastic==
Amazingly, phenolic plastic can apparently sustain the pressure and temperatures generated in braking systems!
