⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on brake systems to prevent electrical issues.
•Allow the vehicle to cool down before servicing the brakes to avoid burns.

Symptoms

•Shaking or vibration felt in the steering wheel during braking
•Pulsation in the brake pedal
•Increased stopping distance
•Uneven wear on brake pads or rotors
•Noise coming from the brakes (grinding or squeaking)

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a caliper gauge.
2
Check brake rotors for warping or uneven surfaces by measuring with a dial indicator.
3
Examine wheel bearings for play or damage by jacking up the vehicle and wiggling the wheel.
4
Inspect tire condition and alignment, checking for uneven wear or damage.
5
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Jack and jack stands
•Lug wrench
•Caliper gauge
•Dial indicator
•OBD-II scanner
•Alignment tool (optional)

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper gauge, dial indicator, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Pads

Lift the front or rear of the vehicle using a jack and secure with jack stands.
Remove the wheel using a lug wrench.
Inspect the brake pads for thickness; replace if less than 3mm.
Remove the caliper bolts with the appropriate socket and slide the caliper off the rotor.
Replace with new brake pads, ensuring proper orientation.
Reinstall the caliper and tighten bolts to the manufacturer’s specifications (typically 25-30 ft-lbs for most models).

3. Resurface or Replace Brake Rotors

If rotors are warped, either machine them using a rotor lathe or replace them with new ones.
For machining, ensure the rotor is within the minimum thickness specification (usually stamped on the rotor).
If replacing, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Install the new rotor, ensuring it sits flush against the hub.
Reinstall the wheel and tighten lug nuts to the manufacturer’s torque specifications.

4. Inspect and Adjust Wheel Alignment

After brakes are serviced, check the alignment using an alignment tool or take the vehicle to a professional alignment shop.
Adjust camber, caster, and toe as required according to manufacturer specifications.
