Diagnostic Steps

1
Inspect brake rotors for warping or damage using a dial indicator.
2
Check brake pads for uneven wear and remaining thickness.
3
Examine wheel balance and alignment with a wheel alignment machine.
4
Inspect suspension components for wear or damage (e.g., control arms, bushings).
5
Scan for any error codes related to the ABS system that may affect braking performance.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lift the vehicle with jack stands.
Disconnect the battery if working on the ABS system.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Use a torque wrench to remove caliper bolts and carefully detach the caliper (support it on a wire to avoid stressing the brake line).
3. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
4. Check rotor thickness and flatness; if warped beyond specifications, replace with new rotors.
5. Install new rotors, ensuring they are clean and free from oil or grease.

3. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Inspect the caliper for damage; if the caliper is seized or damaged, it should be replaced.
3. Install new brake pads, ensuring they are properly seated in the bracket.
4. Reassemble the caliper over the new pads and torque the caliper bolts to manufacturer specifications.

4. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop for precise alignment and balancing.
2. Ensure that all suspension components are in good condition before alignment.
