⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear appropriate safety gear, including gloves and goggles.
•Allow the vehicle to cool before working on the brakes to avoid burns.

Symptoms

•Vibration felt in the steering wheel when applying brakes
•Pulsating brake pedal during braking
•Shaking of the vehicle body when slowing down
•Uneven wear on brake pads or rotors
•Possible noise from the brakes (squeaking or grinding)

Diagnostic Steps

1
Inspect brake rotors for warping using a dial indicator or by checking for uneven surface wear.
2
Check brake pad thickness and condition for wear or damage.
3
Examine suspension components (control arms, bushings, ball joints) for wear or play.
4
Inspect wheel lug nut torque to ensure they are properly tightened.
5
Check for tire imbalance or misalignment by inspecting tire condition and tread wear patterns.

2
Check brake pad thickness and condition for wear or damage.
3

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, brake caliper tool, torque wrench.
Ensure the vehicle is on a flat surface and engage the parking brake. Disconnect the battery if necessary for safety.

2. Remove Wheel

Loosen the lug nuts while the vehicle is still on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Sub-steps:
- Use a dial indicator to measure rotor runout; anything exceeding specifications indicates warping.
- If warped, remove the caliper by unbolting it from the mounting bracket; hang it securely without straining brake lines.
- Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
- Install new rotors, ensuring to clean any protective coating with brake cleaner.
- Torque rotor screws to manufacturer specifications.

4. Inspect and Replace Brake Pads

Sub-steps:
- Check the brake pads for uneven wear; replace if less than the minimum thickness recommended by the manufacturer.
- Compress the caliper piston using a brake caliper tool to allow for new pads.
- Install new pads in the caliper bracket and ensure they are correctly positioned.
- Reattach the caliper over the new pads and torque bolts to manufacturer specifications.

5. Reinstall Wheel and Lower Vehicle

Reattach the wheel and tighten lug nuts to the manufacturer’s torque specifications.
Lower the vehicle and perform a final torque check on the lug nuts.

6. Test Drive

After reassembling, take the vehicle for a short test drive to ensure the brakes are functioning correctly without shaking.
