This procedure covers the replacement of front brake pads on a 2011-2014 Ford F-150 with 3.5L EcoBoost engine, including caliper removal, pad replacement, and proper torque specifications.

Warnings

Tools required

Parts

• Front brake pad set (includes pads for both sides) × 1 — Motorcraft BR-1440 or equivalent
• Brake hardware kit (anti-rattle clips) × 1 — Use OEM specification

Fluids

• Motorcraft DOT 4 LV Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid ground. Place transmission in Park (automatic) or 1st gear (manual). Set parking brake.
2. Open hood and locate brake fluid reservoir. Check fluid level and remove some fluid with turkey baster if reservoir is above MIN line to prevent overflow during piston compression.
3. Loosen front wheel lug nuts approximately one turn while vehicle is still on ground. Do not remove completely.
4. Lift front of vehicle with floor jack at designated front jacking point (check owner's manual for location).
5. Place jack stands under frame rails on both sides. Lower vehicle onto jack stands. Verify stability before working.
6. Remove front wheels completely and set aside.

Procedure

1. 1

   Inspect brake system condition
   Visually inspect the brake rotor for scoring, cracks, or excessive wear. Check brake hoses for cracks, bulges, or fluid leaks. Verify minimum rotor thickness (stamped on rotor). If rotors are damaged or below minimum thickness, they must be replaced. Measure rotor thickness with micrometer if available. Minimum thickness is typically 28mm for F-150, but verify on rotor itself.
2. 2

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the back side of the caliper (facing the engine). These are typically 13mm or 14mm hex head bolts. Using appropriate socket, remove both caliper slide pin bolts completely. Keep track of these bolts as they will be reused. Note: You are removing the caliper only, NOT the caliper bracket.

3. 3

   Remove caliper and support
   Carefully pivot the caliper up and away from the rotor. The caliper will still be attached to the brake hose—do NOT let it hang by the hose. Use wire, a bungee cord, or hook to suspend the caliper from the suspension or frame. Ensure there is no tension on the brake hose.
   ⚠Never allow the caliper to hang by the brake hose. This can damage the hose internally and cause brake failure.
4. 4

   Remove old brake pads and hardware
   Remove the inner and outer brake pads from the caliper bracket. Note the orientation and position of any anti-rattle clips or shims. Remove and discard the old anti-rattle clips and hardware from the caliper bracket. Use wire brush to clean the pad abutment areas on the caliper bracket where the pads make contact.
5. 5

   Compress caliper piston
   Using a C-clamp or brake caliper piston compression tool, slowly compress the caliper piston back into the caliper bore. Place the clamp against the back of the caliper housing and the clamp screw against the piston face (or use old brake pad as buffer). Compress slowly and steadily. Monitor the brake fluid reservoir—it will rise as the piston retracts. Remove excess fluid if necessary to prevent overflow.
   ⚠Watch the master cylinder reservoir closely. If fluid begins to overflow, stop compression and remove fluid from the reservoir.
6. 6

   Install new brake hardware
   Install new anti-rattle clips and hardware onto the caliper bracket according to the hardware kit instructions. Ensure clips are fully seated and secure. Apply a thin layer of high-temperature brake grease to the pad abutment surfaces on the caliper bracket where the pad tabs will slide.
7. 7

   Install new brake pads
   Install the new inner and outer brake pads into the caliper bracket. Ensure the pad wear indicators (if present) are positioned correctly according to pad manufacturer instructions—typically the indicator should be on the inner pad at the top. Verify pads are fully seated in the bracket and hardware clips. Apply a thin layer of high-temperature brake grease to the back of the pad mounting tabs (where they contact the bracket), but do NOT apply grease to the friction surface.
8. 8

   Clean and lubricate caliper slide pins
   Remove the caliper slide pins from the caliper bracket (if not already removed). Clean the pins thoroughly with brake cleaner and wipe dry. Inspect the pin boots for tears or damage—replace if damaged. Apply a generous coating of high-temperature synthetic brake grease to the slide pins. Reinstall the pins into the caliper bracket, ensuring the boots are properly seated.
9. 9

   Reinstall caliper
   Remove the caliper from its supported position. Carefully position the caliper over the new brake pads and align the caliper mounting holes with the slide pins on the bracket. Ensure the brake hose is not twisted.

10. 10

    Torque caliper slide pin bolts
    Thread both caliper slide pin bolts in by hand to ensure proper thread engagement. Using a torque wrench, tighten both caliper slide pin bolts to 38 Nm (28 lb-ft) in a cross pattern. This is a CRITICAL safety torque specification. Verify torque on both bolts.
    ⚠️CRITICAL: Caliper slide pin bolts MUST be torqued to exactly 38 Nm (28 lb-ft). Under-torquing can cause caliper detachment and total brake failure.

    Repeat for opposite side
    Repeat steps 1 through 10 for the opposite front wheel. Always replace brake pads on both sides of the same axle simultaneously to maintain balanced braking.
12. 12

    Reinstall wheels
    Clean the wheel hub face with wire brush to remove rust and debris. Install the wheel onto the hub, ensuring it seats flat. Thread all lug nuts by hand to ensure proper thread engagement. Using a torque wrench in a star/cross pattern, torque lug nuts to 149 Nm (110 lb-ft).
    ⚠️CRITICAL: Wheel lug nuts MUST be torqued to specification in a star pattern. Improper torque can cause wheel detachment.

    Wheel Lug Nuts140 Nm (103 lb-ft)
13. 13

    Lower vehicle and final torque check
    Raise vehicle slightly with jack to remove weight from jack stands. Remove jack stands and lower vehicle completely to ground. With vehicle weight on wheels, perform final torque verification on all lug nuts to 149 Nm (110 lb-ft) in star pattern.

    Restore brake pedal pressure
    Before moving the vehicle, pump the brake pedal slowly and firmly several times until it becomes firm. This seats the brake pads against the rotors. The pedal should feel firm and normal. If pedal goes to the floor, DO NOT drive the vehicle—recheck all work.
    ⚠️CRITICAL: Do NOT attempt to drive the vehicle until brake pedal pressure is restored and feels firm. A soft or sinking pedal indicates a serious problem.
15. 15

    Check brake fluid level and bed pads
    Check the brake fluid reservoir and top off with Motorcraft DOT 4 LV brake fluid to the MAX line if needed. Perform 10-15 gentle stops from 30-40 mph to bed the new pads to the rotors. Avoid hard braking for the first 200 miles to allow proper pad break-in.

Reassembly

1. Ensure all caliper slide pin bolts are torqued to 38 Nm (28 lb-ft)
2. Verify wheel lug nuts are torqued to 149 Nm (110 lb-ft) in star pattern with vehicle on ground
3. Confirm brake fluid level is between MIN and MAX marks
4. Test brake pedal—should be firm and responsive before driving

Verification

• Brake pedal should feel firm and engage normally within first inch of travel
• Perform test stops at low speed in a safe area before returning to normal driving
• No unusual noises (grinding, squealing beyond initial break-in) should be present
• Vehicle should stop straight without pulling to either side
• Recheck wheel lug nut torque after first 50 miles of driving
• Check brake fluid level after first test drive—should remain at proper level
• After 200 miles, verify no fluid leaks at calipers or brake hoses
• If brake warning light illuminates, pedal feels soft, or vehicle pulls during braking, stop driving immediately and have system inspected by a professional
