Diagnostic Steps

1
Inspect brake pads for uneven wear and thickness.
2
Check brake rotors for warping or scoring using a dial indicator.
3
Examine the brake caliper for proper operation and signs of sticking.
4
Verify the condition of suspension components, including struts and control arms.
5
Inspect wheel lug nut torque to ensure proper tightening.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery for safety if working on electrical components.

2. Remove Wheel

Using a socket set, loosen and remove the lug nuts.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket using appropriate socket size.
Slide the caliper off the rotor and support it to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly in the bracket.

4. Inspect and Replace Brake Rotors

If rotors are warped, remove the rotor by unbolting it from the hub.
Clean the hub surface to ensure proper fit of the new rotor.
Install new rotors, and torque the bolts to manufacturer specifications (typically around 80-100 ft-lbs, consult service manual).

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Secure the caliper with bolts, torquing to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the correct specifications.

Tools Required:

Socket set
Torque wrench
Jack and jack stands
Brake cleaner
Dial indicator (for rotor inspection)

Parts Required:

Brake pads
Brake rotors
Brake caliper (if necessary)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Always disconnect the battery before working on braking systems.
Ensure the vehicle is securely lifted and supported before working underneath.
