Diagnostic Steps

1
Inspect brake pads and rotors for uneven wear or damage.
2
Check brake rotor runout using a dial indicator to measure any warping.
3
Examine the brake calipers for proper function and any sticking.
4
Inspect suspension components (e.g., control arms, bushings) for wear or damage.
5
Check tire condition and alignment to ensure no contributing factors.
6
Test drive the vehicle to confirm the symptoms under different braking conditions.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety warning: Use wheel chocks to prevent movement.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads: Check for uneven wear; replace if necessary.
Brake Rotors: Measure rotor thickness and check for warping. If warped, replace the rotors.
Calipers: Inspect for sticking; ensure the caliper slides freely on its pins. Clean and lubricate if needed.

4. Replace Brake Pads and Rotors (if necessary)

If rotors are warped, remove them by unscrewing the retaining bolts.
Install new rotors by aligning them with the hub and securing them with bolts to manufacturer's torque specifications.
Replace brake pads by removing the caliper and sliding out old pads. Insert new pads and reattach the caliper.

5. Reassemble and Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands using the jack.
Tighten lug nuts to the manufacturer's torque specification in a crisscross pattern.
