⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Ensure the vehicle is on a flat surface before lifting.

Symptoms

•Vibration or pulsation felt through the brake pedal during braking
•Increased stopping distance
•Noise during braking (squeaking or grinding)
•Uneven wear on brake pads
•Brake warning light illuminated (in some cases)

Diagnostic Steps

1
Inspect the brake rotors for warping using a dial indicator or a straightedge.
2
Measure the thickness of the brake pads to check for uneven wear.
3
Check the brake fluid level and condition for contamination.
4
Examine calipers for proper operation and signs of sticking.
5
Inspect the suspension components for wear or damage that could affect braking.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Jack and jack stands
•Lug wrench

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (negative terminal) for safety.

2. Remove Wheel and Tire

Using a jack, lift the front or rear of the vehicle depending on which brake is pulsating.
Secure with jack stands for safety.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Remove Brake Caliper

Using a socket set, remove the caliper mounting bolts.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid stress on the brake line.

4. Inspect and Replace Rotors (if warped)

Use a dial indicator to measure rotor run-out. If warping exceeds specifications (typically 0.002 inches), replace the rotors.
If resurfacing is an option, use a brake lathe to machine the rotors to ensure a flat surface.

5. Replace Brake Pads

Remove old brake pads from the caliper bracket.
Clean the caliper bracket and install new brake pads, ensuring they are properly seated.

6. Reassemble Brake Components

Reinstall the caliper over the new brake pads and tighten the mounting bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and tire, tightening the lug nuts in a star pattern to ensure even pressure.

7. Final Checks

Reconnect the battery and check the brake fluid level, topping off as necessary with the appropriate brake fluid (DOT 3 or DOT 4 depending on the F-150 year model).
Perform a short brake test before driving on the road.
