Symptoms

•Vibration or shaking felt in the steering wheel when braking
•Pulsation in the brake pedal
•Uneven wear on brake pads or rotors
•Squeaking or grinding noises during braking
•Reduced braking effectiveness

Diagnostic Steps

1
Inspect brake rotors for warping or damage using a dial indicator.
2
Check brake pads for uneven wear and sufficient thickness.
3
Examine brake calipers for proper operation and any signs of sticking.
4
Inspect suspension components (e.g., control arms, bushings) for wear or damage.
5
Test wheel alignment and balance to rule out related issues.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Remove Wheel and Brake Components

Use a lug wrench to loosen wheel nuts before raising the vehicle.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel and inspect the brake components.

3. Inspect and Replace Brake Rotors (if warped)

Remove the caliper by unbolting it from the bracket (usually requires a socket set).
Slide off the caliper and hang it using a bungee cord to avoid straining the brake line.
Remove the brake pads and measure rotor thickness with a micrometer.
If warped, replace rotors with new ones, ensuring they are properly torqued to specifications (usually around 70-90 ft-lbs, verify for model specifics).

4. Inspect and Replace Brake Pads (if worn)

Check the brake pads for thickness; if less than 3mm, replace them.
Install new brake pads, ensuring they fit snugly in the caliper bracket.

5. Reassemble and Test

Reattach the caliper over the new pads and torque the bolts to the manufacturer’s specifications.
Reinstall the wheel and lower the vehicle.
Torque the wheel nuts to specification (usually around 75-100 ft-lbs).
Reconnect the battery.
