Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for wear and ensure they are within manufacturer specifications.
3
Examine brake calipers for proper operation and ensure they are not sticking.
4
Inspect suspension components (ball joints, tie rods, and control arms) for wear or damage.
5

Solution

1. Preparation

Gather tools and materials needed: jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, new brake pads, new rotors (if necessary).
Ensure the vehicle is parked on a flat surface with the parking brake engaged.

2. Lift Vehicle

Use the lug wrench to loosen the lug nuts on the front wheels slightly (do not remove).
Jack up the vehicle and secure it with jack stands.
Remove the front wheels.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor runout. If the runout is above manufacturer specifications, the rotor is warped.
Removal:
- Remove the caliper mounting bolts using a socket set.
- Hang the caliper securely with a bungee cord; do not let it hang by the brake line.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Replacement:
- Install new rotors, ensuring they are clean and free of grease.
- Torque the rotor retaining screws to manufacturer specifications (typically around 10-15 ft-lbs).

4. Inspect and Replace Brake Pads

Pull out the old brake pads from the caliper bracket.
Inspect the caliper for any signs of wear or damage.
Install new brake pads, ensuring they are seated properly in the caliper bracket.
Apply brake grease to the backing of new pads if recommended by the manufacturer.

5. Reassemble

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (generally 25-35 ft-lbs).
Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 76-89 ft-lbs for a Camry).

6. Test Brakes

Pump the brake pedal a few times to ensure proper brake pad contact.
Check for any unusual noises or sensations during a test drive.
