Front pads and rotors on a Bronco II are a single-afternoon job — two caliper bolts per side, slide the caliper off, swap pads, pull the rotor, install new. Budget about $130 in parts and 2 hours of work.
Front brakes on the Bronco II are a vented disc setup with a single-piston floating caliper. Brake feel on an unrestored truck is usually disappointing — soft pedal, long stopping distances, and a tendency to pull. Half the time the diagnosis is "old pads and warped rotors" and the fix is exactly what this guide covers. The other half is rear drum adjustment, a tired master cylinder, or fluid that hasn't been flushed since the Reagan administration. Do this job, drive it, and decide from there.
Pad choice matters more than rotor choice on this platform. The factory pad was a soft semi-metallic that bites cold and squeals when worn. Wagner ZD194 (ThermoQuiet ceramic) is the most common modern swap and gives quieter braking with less dust. If you're running 31s and the truck sees trail and tow duty, stay with a semi-metallic like the Bendix CFM194 — ceramic compounds shed heat slower under sustained drag. Rotor brands are commodity at this point — Centric, Bosch, ACDelco, R1 Concepts all work. Avoid cheap eBay rotors with no brand markings; they are cast from the wrong grade and warp inside 5,000 miles.
The caliper bolts are 13mm and use slide pins (not pin-and-bushing like later trucks). Pin condition is the make-or-break of this job. Pull each pin, wipe it clean, inspect for rust or pitting, and re-pack with synthetic caliper grease (Permatex Ultra Disc Brake Caliper Lube). A seized pin is the single most common cause of "I replaced the pads and it still pulls and one rotor is hotter than the other."
The caliper piston pushes back into the bore with a C-clamp — use one of the old pads as a pressure spreader. Watch the brake fluid reservoir as you push — if it's full, fluid will overflow. Crack the bleeder if needed. Inspect the rotor surface after you pull the wheel; if you can catch a fingernail in a groove, replace the rotor. If you can't, you can resurface and re-use one time. Rotor torque on the caliper bracket bolts (anchor bolts) is 80 ft-lbs; caliper slide bolts are 25 ft-lbs; lug nuts are 100 ft-lbs.
Bed the pads in: 6–8 moderate stops from 35 to 5 mph, then 2–3 hard stops from 50 to 10, then drive normally for 15 minutes without sitting on the brakes. Bedding transfers a uniform pad layer to the rotor face and is the difference between great brakes and mediocre brakes.
