The E170 Corolla has about the most beginner-friendly front brake setup Toyota sells: a single-piston floating caliper on a 275 mm vented rotor, two 14 mm slide bolts, two 17 mm bracket bolts and no rotor retaining screw to snap off. If you have done brakes on any modern Toyota, this will feel familiar, and a first-timer can finish both sides in an afternoon with hand tools.
The one thing people get wrong is skipping the slide pins. Corollas in salt states commonly seize a pin in its bore, which makes one pad wear twice as fast as the other and cooks the new rotor. Pull both pins, clean them, re-grease with silicone brake grease, and replace any torn boots while you are in there. The second most common mistake is not drawing fluid out of the reservoir before compressing the pistons, which pushes old fluid up and over the top.

The 14 mm slide bolts, 17 mm bracket bolts and 21 mm lug nuts are consistent across the 2014-2019 E170 Corolla, but verify the torque figures against the Toyota service manual for your exact model year and trim.
The two caliper slide bolts take a 14 mm socket, and the two caliper bracket bolts on the steering knuckle take a 17 mm. Lug nuts are 21 mm.
No, E170 Corolla front rotors slide straight off the hub once the caliper bracket is removed. If one is stuck by rust, thread two M8x1.25 bolts into the rotor's threaded jacking holes and turn them evenly to press it off.
Yes, if the rotors are above the minimum thickness stamped on the hat (typically 20 mm on a 22 mm new rotor) and have no scoring or pulsation. Measure with a micrometer at several points before deciding.
No. The E170 Corolla uses a cable-operated parking brake on the rear drums or rear discs, so the front brake job needs no scan tool and no retract procedure.
