⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow brakes to cool before handling components.

Symptoms

•Steering wheel shakes or vibrates when braking
•Vehicle feels unstable or pulls to one side
•Increased stopping distance
•Brake pedal pulsates when pressed
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear.
2
Check brake pads for thickness and even wear.
3
Examine the suspension components for damage or wear (e.g., control arms, bushings).
4
Test wheel alignment to ensure proper tracking.
5
Inspect tires for uneven wear or damage.
6
Use an OBD-II scanner to check for any brake system-related error codes.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Inspect Rotors:
- Remove the wheel to access the brake components.
- Use a caliper gauge to measure rotor thickness.
- Check for signs of warping using a dial indicator.
Replace Rotors (if necessary):
- Remove the caliper (using a socket set) and hang it securely without stressing the brake line.
- Remove the rotor retaining screws if present and slide the old rotor off the hub.
- Clean the hub surface to ensure a proper fit for the new rotor.
- Install the new rotor and torque the retaining screws to manufacturer specifications (typically 10-15 lb-ft).

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Measure the pad thickness; if below 3mm, they should be replaced.
- Ensure even wear across all pads.
Replace Brake Pads (if necessary):
- Remove the caliper bracket and guide pins using a socket set.
- Replace the old pads with new ones, ensuring they fit snugly into the caliper bracket.
- Reassemble the caliper, ensuring it operates smoothly.

4. Suspension Components Check

Inspect ball joints, control arms, and bushings for wear or damage.
Replace any worn or damaged components, ensuring proper torque specifications when reassembling.

5. Wheel Alignment

After replacing any components, check wheel alignment using an alignment machine.
Adjust as necessary to manufacturer specifications.
