Steps

Replace the front brake caliper on a 2011-2014 Ford F-150 5.0L V8, including bleeding the brake system to restore proper braking performance.

Warnings

⚠️Brake system failure can result in loss of vehicle control, collision, serious injury or death. If you are uncertain about any step in this procedure, have the vehicle serviced by a qualified technician.

⚠️Never work under a vehicle supported only by a jack. Always use jack stands rated for the vehicle weight and position them on solid frame contact points.

⚠️Brake fluid is corrosive and will damage paint. It is also hygroscopic and absorbs moisture - use only fresh fluid from a sealed container and dispose of old fluid properly.

⚠Do not allow brake fluid reservoir to run empty during this procedure or air will enter the ABS hydraulic unit, requiring professional scan tool bleeding procedures.

⚠Copper crush washers on banjo bolts must be replaced every time the connection is opened. Reusing old washers will cause brake fluid leaks.

ℹ️This procedure covers one front caliper. Calipers should generally be replaced in axle pairs to maintain balanced braking performance.

Tools required

Floor jack and jack stands rated for vehicle weightEssential

Torque wrench (10-200 Nm range)Essential

Socket set (including 18mm, 21mm sockets)Essential

Brake line wrench or flare nut wrench (appropriate size)Essential

Brake bleeder kit or clear hose and catch bottleEssential

C-clamp or brake caliper piston tool

Wire brush

Brake cleaner

Drip panEssential

Turkey baster or fluid transfer pump

Parts

Front brake caliper (left or right as needed) × 1 — Use OEM specification
Copper crush washers for banjo bolt × 2 — Typically 2 per banjo bolt
Thread locker (medium strength) × 1 — Loctite 243 or equivalent

Fluids

Motorcraft DOT 4 LV Brake Fluid — 0.5 qt

Preparation

Park vehicle on level surface and set parking brake firmly
Chock rear wheels to prevent vehicle movement
Using turkey baster or fluid transfer pump, remove approximately half the brake fluid from master cylinder reservoir to prevent overflow when compressing caliper piston
Loosen wheel lug nuts on the wheel where caliper will be replaced (do not remove yet)
Raise front of vehicle with floor jack at manufacturer-specified jacking point
Secure vehicle on jack stands positioned at frame contact points - verify stability before working
Remove wheel and tire assembly completely
Clean brake caliper area with brake cleaner and wire brush to remove road grime and corrosion

Procedure

1
Disconnect brake hose from caliper
Place drip pan under caliper area. Using a brake line wrench to prevent rounding, loosen and remove the brake hose banjo bolt connecting the flexible brake hose to the caliper. Immediately plug the hose end with a rubber cap or wrap in plastic to minimize fluid loss and prevent contamination. Discard the old copper crush washers - do not reuse them.
2
Remove caliper slide bolts
Locate the two caliper slide bolts (also called guide pins) on the rear side of the caliper. These are typically 18mm bolts. Using appropriate socket, remove both caliper slide bolts completely. Support the caliper while removing the second bolt to prevent it from falling.
3
Remove old caliper from bracket
Lift the caliper assembly off the brake rotor and caliper bracket. The caliper may be stuck due to corrosion - gently work it free if needed. Carefully set aside the old caliper. Inspect the brake pads and rotor for unusual wear patterns that might indicate other suspension or brake issues.
4
Inspect caliper bracket and hardware
With caliper removed, inspect the caliper bracket mounting bolts for damage or excessive corrosion. Check that brake pad slide hardware is in good condition. Clean the caliper bracket contact points with wire brush and brake cleaner. If replacing both calipers on the axle, this is an appropriate time to inspect or replace rotors and brake pads.
5
Prepare new caliper for installation
Remove protective caps from new caliper. Verify that caliper piston is fully retracted - if not, carefully compress it using a C-clamp or caliper piston tool. Ensure bleeder screw moves freely (do not remove completely). Clean any preservative oil from caliper mounting surfaces with brake cleaner.
6
Install new caliper onto bracket
Position new caliper over brake rotor and onto caliper bracket, ensuring brake pads (if installed) seat properly on both sides of rotor. Align caliper slide bolt holes with bracket. Verify that caliper movement is smooth and unobstructed before proceeding.
7
Install and torque caliper slide bolts
Apply a small amount of medium-strength thread locker to the caliper slide bolt threads. Insert both caliper slide bolts and hand-tighten. Using torque wrench, tighten caliper bolts to specification in a cross pattern to ensure even seating. Verify caliper is firmly secured and has no excessive play.
8
Connect brake hose to new caliper
Remove plug or plastic wrap from brake hose. Install NEW copper crush washers on both sides of the banjo fitting (one washer between fitting and caliper body, one washer between banjo bolt head and fitting). Thread banjo bolt by hand to ensure proper threading, then torque to specification using torque wrench. Do not overtighten.
9
Bleed brake caliper
Attach clear hose to bleeder screw and submerge opposite end in container with small amount of clean brake fluid. Have assistant pump brake pedal 3-4 times and hold pressure. Open bleeder screw 1/2 turn - fluid and air will escape. Close bleeder screw before pedal reaches floor. Repeat until fluid flows clear without air bubbles. Top off master cylinder frequently during bleeding to prevent running dry. Tighten bleeder screw to specification when complete.

Inspect for leaks and verify operation
With assistant maintaining firm brake pedal pressure, carefully inspect banjo bolt connection and bleeder screw for any brake fluid seepage. Wipe connections clean and observe for 30 seconds. Any leakage indicates improper torque or damaged washers - correct immediately. Verify brake pedal feels firm and does not sink slowly to floor.
11
Reinstall wheel and lower vehicle
Clean wheel mounting surface on hub with wire brush. Reinstall wheel and tire assembly, threading lug nuts by hand initially. Tighten lug nuts in star pattern to torque specification using torque wrench. Lower vehicle from jack stands using floor jack. With vehicle weight on ground, re-torque lug nuts in star pattern to final specification.

Reassembly

Fill master cylinder reservoir to MAX line with fresh Motorcraft DOT 4 LV brake fluid from sealed container
Clean any spilled brake fluid from painted surfaces immediately with water
If both front calipers were replaced, bleed the opposite side caliper following the same procedure in step 9

Verification

With engine running, pump brake pedal several times - pedal should feel firm and consistent, not spongy or soft
Verify brake pedal does not slowly sink to floor when held under constant pressure with engine running
Perform test stops at low speed (5-10 mph) in safe area to confirm braking response before returning to normal driving
Check for brake fluid leaks at banjo bolt connection after test stops - retorque if any seepage observed
Verify brake fluid level in master cylinder reservoir is between MIN and MAX marks
Monitor brake warning light on instrument cluster - light should be OFF with parking brake released
Before returning vehicle to service, perform several moderate stops from 30-40 mph to bed in new caliper and pads
Re-check all torque specifications and fluid level after first 50 miles of driving
