Replace front brake pads on 2015-2020 Ford F-150 with 5.0L V8. This procedure involves removing the caliper slide pins, retracting the caliper pistons, and installing new brake pads.

Warnings

Tools required

Parts

• Front brake pad set (includes pads for both sides) × 1 — Use OEM Ford specification or quality aftermarket equivalent
• Brake hardware kit (anti-rattle clips, shims) × 1 — Often included with pad set
• Thread locker (medium strength) × 1 — Loctite 243 or equivalent

Fluids

• Motorcraft DOT 4 LV Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid surface. Place wheel chocks behind rear wheels.
2. Loosen front lug nuts 1/4 turn while wheels are on ground, but do not remove.
3. Lift front of vehicle with floor jack at designated front jacking point and support securely on jack stands at frame rails.
4. Remove front wheels completely and set aside.
5. Inspect brake rotors for wear, scoring, or damage. Measure rotor thickness if possible. Replace rotors if below minimum specification (typically stamped on rotor hat).
6. Remove approximately 1/3 of brake fluid from master cylinder reservoir using turkey baster or syringe. This prevents overflow when compressing caliper pistons. Store removed fluid in sealed container for disposal.

Procedure

1. 1

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the rear of the caliper assembly. These typically require a 13mm hex socket or wrench. Remove both caliper slide pin bolts completely. Note: These are the slide pins that allow the caliper to float, not the larger bracket bolts that mount the entire assembly to the knuckle.

2. 2

   Pivot caliper upward
   With slide pin bolts removed, carefully pivot the caliper body upward and away from the rotor. The caliper will swing up on the brake hose - do not let it hang by the hose. Support the caliper with a wire hook or bungee cord attached to the suspension or frame to prevent stress on the brake hose.
3. 3

   Remove old brake pads
   Remove the inner and outer brake pads from the caliper bracket. Note the orientation and position of any anti-rattle clips or shims attached to the pads. Take a photo for reference if needed. Remove and discard the old hardware clips from the bracket abutments.
4. 4

   Inspect and clean caliper bracket
   Inspect the caliper bracket slide surfaces (abutments) where the pads contact. Use a wire brush to clean any rust, corrosion, or debris from these surfaces. Clean the bracket with brake parts cleaner. Inspect the rubber dust boots on the slide pins for tears or damage - replace if compromised.
5. 5

   Compress caliper pistons
   Using a C-clamp or brake caliper piston compression tool, slowly compress the caliper pistons fully into the caliper bore. Place the clamp against the back of the caliper body and the inner piston surface. Compress gradually and evenly. Watch the brake fluid reservoir - it should rise but not overflow. If fluid overflows, remove more fluid before continuing.
6. 6

   Install new brake hardware
   Install the new anti-rattle clips and hardware from the brake pad kit onto the caliper bracket abutments. Ensure clips are fully seated and secure. Apply a thin layer of high-temperature brake caliper grease to the abutment surfaces where the pad backing plates will slide, but keep grease away from friction material and rotor surfaces.
7. 7

   Install new brake pads
   Install the new inner and outer brake pads into the caliper bracket. Ensure pads are properly seated in the hardware clips with wear indicators (if present) positioned correctly. Wear indicators should face toward the rear of the vehicle on most designs - verify with pad manufacturer instructions. Ensure friction material faces the rotor.
8. 8

   Lubricate caliper slide pins
   Remove the caliper slide pins from the bracket (if not already removed). Clean the pins thoroughly with brake cleaner and inspect for corrosion or damage. Apply a generous coating of high-temperature synthetic brake caliper grease to the slide pins along their entire length. Do not use standard grease as it will fail under brake temperatures. Reinstall pins into bracket boots.
9. 9

   Reinstall caliper and torque slide pin bolts
   Swing the caliper back down over the new brake pads and align the slide pin bolt holes. Apply a small amount of medium-strength thread locker to the slide pin bolt threads. Install both caliper slide pin bolts and tighten by hand initially. Torque the caliper slide pin bolts to specification using a torque wrench in a crisscross pattern.

    Repeat for opposite side
    Repeat steps 1-9 for the opposite front brake assembly. Always replace brake pads on both sides of the same axle together to maintain balanced braking performance.
11. 11

    Reinstall wheels
    Mount the front wheels onto the hubs. Install lug nuts and tighten by hand until snug. Lower the vehicle so the wheels just contact the ground but the suspension is not fully loaded.
12. 12

    Torque lug nuts
    Using a torque wrench, tighten the lug nuts to specification in a star pattern (not circular). Make at least two complete passes through the star pattern to ensure even seating. Note: Verify your specific F-150 model's lug nut torque specification - common specs are 150 lb-ft or 120 lb-ft depending on wheel type.

    Restore brake pedal
    With vehicle still supported, start the engine (if not already running). Pump the brake pedal slowly and deliberately 10-15 times until the pedal feels firm and achieves normal height. This repositions the caliper pistons against the new pads. Check the brake fluid reservoir and top off with Motorcraft DOT 4 LV brake fluid to the MAX line if necessary.

Reassembly

1. Remove jack stands and completely lower the vehicle to the ground.
2. Perform a final torque check of all lug nuts in star pattern.
3. Clean any brake fluid spills or drips from components and paint surfaces.
4. Dispose of old brake pads and fluid according to local environmental regulations.

Verification

• With engine running, pump brake pedal several times and verify it achieves firm, normal pedal height and feel. Pedal should not sink or feel spongy.
• Check brake fluid level in reservoir - should be at MAX line with new pads installed.
• Inspect around calipers for any brake fluid leaks from disturbed hoses or fittings.
• Test drive vehicle at low speed (under 10 mph) in a safe area and verify brakes engage smoothly and vehicle stops straight without pulling to either side.
• Perform several moderate brake applications from 30-40 mph to begin bedding-in new pads.
• IMPORTANT: New brake pads require a break-in (bedding) period. Avoid hard stops for the first 200-300 miles. Follow pad manufacturer's bedding procedure if provided.
• After first test drive and again after 50 miles, re-check lug nut torque.
• Listen for any abnormal noises (squealing, grinding, rubbing) during brake application - investigate immediately if present.
