Diagnostic Steps

1
Inspect brake rotors for warping using a runout gauge.
2
Check brake pads for uneven wear or damage.
3
Examine brake calipers for proper functioning and ensure they are not sticking.
4
Inspect suspension components for wear or damage that could affect braking.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Tools required: Socket set, jack, and jack stands.
Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Rotors

Check for warping using a runout gauge; if warped beyond specifications, replace.
If rotors are within specifications but have uneven wear, consider resurfacing.

B. Inspect Brake Pads

Remove caliper bolts with a socket.
Slide the caliper off the rotor and hang it with a bungee cord (do not let it dangle by the brake line).
Inspect the brake pads for thickness; replace if worn below the minimum specification.

4. Reassemble and Torque

Reinstall caliper over the new or resurfaced rotor.
Torque caliper bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and torque lug nuts in a crisscross pattern to the specified torque (typically 100-110 ft-lbs).

5. Test Drive

Lower the vehicle off the jack stands.
Test drive the vehicle at low speeds to ensure the brakes function correctly and vibrations are resolved.
