Diagnostic Steps

1
Inspect brake rotors for warping by measuring runout with a dial indicator.
2
Check brake pads for even wear and proper thickness.
3
Examine suspension components (tie rods, control arms) for wear or damage.
4
Inspect wheel alignment and tire condition for uneven wear or imbalance.
5

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Rotors

Check for Warping: Measure the rotor runout using a dial indicator; if it exceeds manufacturer specifications, replace the rotor.
Remove the Caliper: Unbolt the caliper from its bracket and hang it using a bungee cord (do not let it hang by the brake line).
Remove the Rotor: If it’s stuck, tap it gently with a rubber mallet. Remove the rotor from the hub.
Install New Rotor: Position the new rotor onto the hub and secure it.

4. Inspect and Replace Brake Pads

Remove Old Pads: Slide the old brake pads out of the caliper bracket.
Install New Pads: Apply brake grease to the backs of the new pads and insert them into the caliper bracket.
Reattach Caliper: Reposition the caliper over the new pads and torque the bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.
Repeat for all wheels if necessary.

6. Test Drive

After completing the repairs, perform a test drive to ensure braking performance is restored and no shaking occurs.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Dial indicator (for measuring rotor runout)
Brake cleaner
Brake grease

Parts Required:

New brake rotors
New brake pads

Estimated Repair Time: 2-4 hours

Safety Warnings:
