⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the vehicle to cool before working on brake components to avoid burns.
•Ensure the vehicle is securely lifted and supported before working underneath.

Symptoms

•Vehicle shakes or vibrates during braking
•Pulsation felt in the brake pedal
•Steering wheel vibration while braking
•Increased stopping distance
•Unusual noise when braking (e.g., grinding or squeaking)

Diagnostic Steps

1
Inspect brake components visually for wear or damage, including rotors, pads, and calipers.
2
Check brake rotor runout using a dial indicator to determine if rotors are warped.
3
Examine suspension components (e.g., control arms, struts) for wear or play.
4
Test drive the vehicle to confirm the conditions under which the shaking occurs.
5
Scan for any error codes related to the ABS 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

•Lug wrench
•Socket set
•Torque wrench
•Dial indicator (for rotor runout check)
•OBD-II scanner

Parts Required

•Brake pads

Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Brake Pads

Remove the wheel using a lug wrench to access the brake assembly.
Inspect the brake pads for thickness and wear; if less than 3mm, replace.
Use a socket set to remove the caliper bolts, then gently slide the caliper off the rotor.
Remove the old brake pads and replace them with new ones, ensuring they fit snugly.
Reinstall the caliper, tightening bolts to manufacturer's torque specifications (typically 25-35 Nm).

3. Inspect and Replace Brake Rotors (if necessary)

With the caliper removed, inspect the brake rotor for signs of warping or scoring.
If warped, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Install new rotors, ensuring they are clean and free from oil or debris.
Torque the rotor retaining screws to the manufacturer's specifications (typically 10-15 Nm).

4. Check and Repair Suspension Components

Inspect suspension components for any signs of wear, such as bushings or ball joints.
Replace any worn or damaged components, following manufacturer specifications for torque settings during reinstallation.

5. Reassemble and Test

Reinstall the wheel and ensure lug nuts are torqued to the specified value (typically 90-100 Nm).
Reconnect the negative battery terminal.
Test drive the vehicle to verify that the shaking during braking has been resolved.
