Front Brake Theory Of Operation

[NGO]

Stupid question ... While changing out my front pads last night (thanks Sebring) it dawned on me that i just dont understand how the outside pads move in to make contact with the rotor. The inside pads have the pistons pushing on them but the outside? School me please

The piston also generates friction on the outside pad. The caliper will slide on the caliper bracket. Since the outer pad is on the caliper it slides over with the caliper to make contact with the rotor.

The piston side of the caliper uses the 'sliding' (outer) side of the caliper to get it's leverage from. Hence, both sides of the caliper (along with the pads) get relatively the same amount of pressure.

Where the term 'floating caliper' comes from.

FWIW
