Important safety information - read before proceeding

•Ensure the vehicle is securely supported on jack stands before working underneath.
•Allow brake components to cool before handling if the vehicle has been driven recently.

Symptoms

•Vehicle shakes or vibrates during braking
•Pulsation felt in the brake pedal
•Uneven wear on brake pads
•Increased stopping distance
•Possible noise (grinding or squeaking) from brake components

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for wear, ensuring they have sufficient material left.
3
Examine suspension components (control arms, bushings, struts) for wear or damage.
4
Inspect wheel bearings for play or roughness by shaking the wheel at 12 and 6 o'clock positions.
5
Verify tire condition and pressure, checking for uneven wear or damage.

Solution

1. Preparation

Gather tools required: jack, jack stands, lug wrench, torque wrench, dial indicator, brake cleaner, and safety glasses.
Ensure the vehicle is on a level surface, and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Braking Components

Brake Rotors:
- Measure rotor thickness and check for warping using a dial indicator; replace if warped beyond manufacturer specifications.
- Clean the rotor surface with brake cleaner to remove any debris.
Brake Pads:
- Inspect brake pads for thickness; replace if they are below 3mm.
- Check for uneven wear patterns and replace pads if necessary.

4. Replace Brake Rotors (if necessary)

Remove caliper brackets by unscrewing the bolts.
Slide off the old rotor and install the new rotor, ensuring it sits flush against the hub.
Reinstall caliper brackets and torque bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten lug nuts to the specified torque.
Test drive the vehicle to ensure the braking issue is resolved.
