Replace the front brake hose connecting the brake line to the caliper, restoring hydraulic integrity to the front brake system.

Warnings

Tools required

Parts

• Front brake hose × 1 — Use OEM specification
• Copper crush washers for banjo bolt × 2 — Two required per hose
• Brake hose retaining clip (if damaged) × 1 — Inspect during removal

Fluids

• Motorcraft DOT 4 LV Brake Fluid — 0.5 qt

Preparation

1. Park vehicle on level ground, engage parking brake, and chock rear wheels
2. Open hood and locate brake fluid reservoir. Remove approximately half the fluid using a turkey baster or fluid syringe to prevent overflow during hose removal
3. Loosen front wheel lug nuts while vehicle is on ground
4. Raise front of vehicle with floor jack and support securely on jack stands at frame rails
5. Remove front wheel completely
6. Spray penetrating oil on brake hose banjo bolt, brake line fitting, and bracket mounting points. Allow 10-15 minutes to penetrate
7. Prepare brake fluid catch container and position under work area

Procedure

1. 1

   Disconnect brake hose from caliper
   Locate the banjo bolt connecting the brake hose to the caliper on the back side of the caliper body. Position catch container below connection point. Using a line wrench, hold the brake hose fitting stationary while loosening the banjo bolt with a 10mm wrench or socket. Remove the banjo bolt completely and immediately plug the caliper port with a rubber cap or clean shop rag to minimize fluid loss. Remove and discard both copper crush washers from the banjo fitting.
   ⚠Brake fluid will begin draining immediately upon loosening. Have catch container ready.

2. 2

   Disconnect brake line from brake hose
   Locate the brake line-to-hose junction, typically near the frame rail or strut tower. Using a flare nut wrench (not a standard wrench, which can round the fitting), carefully loosen the brake line fitting from the brake hose. The flare nut wrench prevents damage to the soft metal fitting. Once loose, unthread by hand and allow fluid to drain into container. Cap or plug the brake line end to prevent contamination.
   ⚠Use only a flare nut wrench on brake line fittings. Standard wrenches will round the soft fitting and require line replacement.
3. 3

   Remove brake hose from mounting bracket
   Locate the brake hose mounting bracket on the frame rail or suspension component. Remove the retaining clip (horseshoe clip or spring clip) securing the hose to the bracket. If equipped with a bolt-through bracket, remove the bracket bolt. Note the orientation of any washers or spacers. Carefully withdraw the brake hose from the bracket, noting routing for reinstallation.

   Inspect and clean mounting points
   Inspect the caliper banjo port threads and brake line fitting threads for damage, corrosion, or cross-threading. Clean threads with a wire brush if necessary. Inspect the mounting bracket for damage or excessive corrosion. If bracket bolt threads are damaged, repair or replace bracket before proceeding. Verify the new brake hose matches the old hose in length, fitting type, and bracket configuration.
   ⚠Damaged threads can prevent proper torque and cause brake failure. Replace any damaged components before proceeding.
5. 5

   Route new brake hose through bracket
   Route the new brake hose through the mounting bracket in the same orientation as the original. Ensure the hose is not twisted and follows the original path. Install the hose into the bracket and secure with the retaining clip or bracket bolt. If using a bolt, hand-tighten only at this stage to allow for final positioning adjustment. Verify the hose has adequate clearance from suspension components, steering components, and the tire throughout the full range of suspension travel and steering motion.
   ⚠️Brake hose must have clearance from all moving components. Contact with tire or suspension will cause hose failure and complete brake loss.
6. 6

   Connect brake line to brake hose
   Remove the cap from the brake line end. Thread the brake line fitting into the brake hose by hand, ensuring it threads smoothly without resistance (indicating proper alignment). Once hand-tight, use a flare nut wrench to snug the fitting. Do not fully tighten yet, as hose positioning may need adjustment. Verify the hose is not twisted at this connection point.
   ⚠Cross-threading will destroy the fitting. If resistance is felt, back out and restart. Fitting should thread smoothly by hand.
7. 7

   Connect brake hose to caliper
   Install a NEW copper crush washer on each side of the banjo fitting (one against the banjo, one between the banjo and caliper). Position the banjo fitting onto the caliper port, ensuring proper alignment. Insert the banjo bolt and thread by hand until seated. Verify both copper washers are in place. Using a torque wrench, tighten the banjo bolt to specification. Do not overtighten, as this can damage the caliper threads or prevent proper sealing.
   ⚠️NEW copper washers are mandatory. Reused washers will not seal properly and will cause brake fluid leaks and potential brake failure.

   Finalize hose positioning and tighten connections
   With both ends connected, verify the brake hose routing one final time. The hose should have smooth curves with no kinks or twists, and must clear all suspension and steering components through their full range of motion. If equipped with bracket bolt, torque to specification. Using a flare nut wrench, tighten the brake line fitting firmly (typically 10-12 lb-ft, but specific torque not provided—tighten firmly without excessive force). Ensure hose is not twisted at connection points.

   Bleed brake system
   Refill the brake fluid reservoir to the MAX line with fresh Motorcraft DOT 4 LV brake fluid. Attach bleeder hose and catch bottle to the caliper bleeder screw. Have an assistant pump the brake pedal 3-4 times and hold firm pressure. Open the bleeder screw 1/4 turn while assistant maintains pedal pressure. Close bleeder before pedal reaches floor. Repeat until fluid flows clear without air bubbles (typically 6-10 cycles). Tighten bleeder screw to specification. Maintain reservoir level above MIN throughout bleeding process.
   ⚠️Never allow the brake fluid reservoir to run dry during bleeding. This will introduce air into the ABS system, requiring professional scan tool bleeding.
   ⚠Assistant must not release pedal while bleeder is open, or air will be drawn back into the system.

    Inspect for leaks
    With engine off, pump brake pedal firmly 10-15 times to pressurize the system. Carefully inspect the banjo bolt connection at the caliper, the brake line fitting connection, and the bracket area for any signs of brake fluid seepage. Wipe all connections dry and re-inspect. If any leaks are found, depressurize system, correct the issue (verify new washers, proper torque, undamaged threads), and rebleed.
    ⚠️Any brake fluid leak is unacceptable and indicates system failure. Do not proceed if leaks are present.
11. 11

    Reinstall wheel and lower vehicle
    Reinstall the front wheel, threading lug nuts by hand to ensure proper seating. Tighten lug nuts in a star pattern using a torque wrench to specification. Lower vehicle from jack stands to ground. With vehicle weight on wheels, perform final torque check on lug nuts in star pattern.

Reassembly

1. Top off brake fluid reservoir to MAX line with fresh Motorcraft DOT 4 LV brake fluid
2. Ensure reservoir cap is securely installed to prevent moisture contamination
3. Clean any spilled brake fluid from painted surfaces immediately with water
4. Dispose of old brake fluid and used copper washers properly at a recycling center

Verification

• With engine running, pump brake pedal several times. Pedal should feel firm and consistent, with no excessive travel or sponginess
• Perform brake pedal firmness test: apply firm pressure and hold for 30 seconds. Pedal should not sink or feel soft
• Start engine and verify brake warning light is off on instrument cluster
• Visually inspect all brake connections one final time for any signs of fluid seepage
• Perform low-speed test in a safe area: at 5-10 mph, apply brakes firmly. Vehicle should stop straight and promptly without pulling
• Perform moderate-speed test: at 20-25 mph in a safe area, apply brakes progressively. Verify normal stopping power and pedal feel
• If pedal feels soft, ABS light is on, or vehicle pulls during braking, do NOT drive. Re-inspect work and bleed system again, or seek professional service
• Test drive cautiously, maintaining extra following distance for the first 50 miles while bedding new connections
