Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system.
•Allow the vehicle to cool before handling any components near hot brakes.

Symptoms

•Vibration felt in the steering wheel or brake pedal when braking
•Pulsating sensation while applying the brakes
•Increased stopping distance
•Unusual noise during braking (grinding or squeaking)
•Uneven brake wear (visible upon inspection)

Diagnostic Steps

1
Inspect brake pads for uneven wear or damage.
2
Check brake rotors for warping or scoring using a run-out gauge.
3
Examine brake calipers for proper operation and any signs of sticking.
4
Inspect suspension components (e.g., control arms, bushings) for wear or damage.
5
Verify wheel alignment and balance to rule out contributing factors.
6
Scan for any brake-related error codes using a diagnostic scanner.

Solution

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the braking system.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel using a socket set.
- Inspect brake pads for thickness and wear; replace if less than 3mm.
- If replacement is necessary, remove the caliper bolts and slide the caliper off.
- Replace the old pads with new ones, ensuring they are correctly positioned.
- Reinstall the caliper and torque the bolts to the manufacturer’s specifications (typically around 80-100 Nm).

3. Check and Replace Brake Rotors

Sub-steps:
- Inspect the brake rotors for warping or scoring; if warped, replace the rotors.
- Remove the caliper and bracket to access the rotor; note the bolt torque specifications for reinstallation.
- Remove the rotor by unscrewing retaining screws if present; otherwise, it may require tapping gently with a hammer.
- Install new rotors, ensuring they are clean and free of oil; torque the retaining screws as specified.
- Reattach the caliper and torque it accordingly.

4. Inspect and Repair Suspension Components

Sub-steps:
- Visually inspect control arms, bushings, struts, and other suspension parts for wear.
- Replace any damaged components with OEM or quality aftermarket parts.
- Ensure all bolts are torqued to the manufacturer's specifications.

5. Wheel Alignment and Balancing

Sub-steps:
- After completing brake repairs, have the vehicle's wheel alignment checked and adjusted.
- Balance the wheels to ensure even tire wear and handling performance.
