2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the brake components to cool before working on them to prevent burns.
•Reconnect the battery terminal only after completing all repairs.

Symptoms

•Steering wheel vibrates during braking
•Vehicle shakes or shudders when slowing down
•Uneven brake pad wear
•Pulsating brake pedal feel
•Increased stopping distance
•Potential noise from brakes (squeaking or grinding)

Diagnostic Steps

1
Inspect brake pads and rotors for wear and damage.
2
Check wheel alignment and balance for any inconsistencies.
3
Measure rotor thickness and check for warpage using a dial indicator.
4
Examine suspension components (e.g., control arms, bushings) for wear or damage.
5
Test the brake calipers for proper operation and ensure they are not sticking.
6
Scan the vehicle for any ABS fault codes.

Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.
Disconnect the negative battery terminal.

2. Brake Component Inspection

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for uneven wear; replace if worn below specifications.
3. Check brake rotors for scoring, rust, or warping; replace if necessary.

Tools Required:

Socket set
Torque wrench
Brake cleaner

3. Brake Rotor Replacement (if needed)

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts and securing it away from the rotor.
2. Remove the brake rotor; if it's stuck, gently tap it with a rubber mallet.
3. Install the new rotor, ensuring it is properly seated.
4. Reinstall the brake caliper and tighten to manufacturer specifications (typically 25-35 Nm).

4. Suspension Component Check

Sub-steps:
1. Inspect control arms, bushings, and tie rods for any visible wear or damage.
2. Replace any worn components to ensure proper alignment and handling.

Tools Required:

Torque wrench
Pry bar for bushings (if necessary)

5. Wheel Alignment and Balancing

Sub-steps:
1. After all components are replaced or repaired, take the vehicle to a professional shop for alignment.
2. Ensure wheels are balanced to prevent any vibrations while driving.
