Diagnostic Steps

1
Inspect brake pads for wear and evenness.
2
Check brake rotors for warping or damage using a runout gauge.
3
Examine wheel lug nut torque for proper specification.
4
Inspect the brake calipers for sticking or malfunction.
5
Evaluate suspension components for wear or damage.
6
Check tire balance and alignment.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear tires for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check for uneven wear; if the pads are worn down, replace them.
Replacement Procedure:
1. Remove the caliper bolts using a socket set.
2. Slide the caliper off the rotor and support it, do not let it hang by the brake line.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads in the caliper bracket.
5. Compress the caliper piston using a brake caliper tool.
6. Reattach the caliper over the new pads and tighten the caliper bolts to manufacturer specifications.

4. Inspect and Resurface/Replace Brake Rotors

Inspect Rotors: Check for warping or scoring using a dial indicator.
Resurfacing Procedure:
1. If rotors are within specifications, they can be resurfaced. Otherwise, remove and replace them.
2. Remove rotor retaining screws if applicable and slide the rotor off the hub.
3. Take rotors to a machine shop for resurfacing or replace with new rotors.
4. If replacing, install the new rotor and tighten retaining screws if applicable.

5. Reassemble and Torque

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specifications (usually around 150 lb-ft for F-150).
