⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on the braking system.
•Allow the vehicle to cool if brakes have been recently used to avoid burns.

Symptoms

•Shaking or vibrating sensation in the steering wheel during braking
•Increased pedal feel resistance while braking
•Unusual noises coming from the brakes (squeaking or grinding)
•Potential pull to one side during braking
•Uneven tire wear observed on the front tires

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual check.
2
Check brake rotors for warping or uneven surfaces using a dial indicator or straightedge.
3
Examine wheel alignment and suspension components for any signs of damage or misalignment.
4
Check tire pressure and inspect tires for balancing issues or deformities.
5
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the 12V battery for safety before working on the braking system.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pad thickness; if below manufacturer specifications, remove the old pads.
3. Install new brake pads by sliding them into the caliper bracket.
4. Reinstall the wheel and torque the lug nuts to manufacturer specifications.

Tools Required:

Socket set
Torque wrench

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Remove the brake caliper using a socket set and hang it securely to avoid stress on the brake line.
2. Remove the rotor from the hub.
3. Inspect the rotor for warping using a dial indicator. If warped beyond tolerance, replace; if minor, resurface.
4. Reinstall the rotor and caliper, ensuring all bolts are torqued to specifications.

Tools Required:

Dial indicator
Brake rotor resurfacing tool (if applicable)

4. Wheel Alignment Check

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have the alignment checked and adjusted as necessary to manufacturer specifications.

Tools Required:

None (performed by alignment technician)

5. Tire Inspection and Balancing

Sub-steps:
1. Inspect tires for any signs of uneven wear or damage.
2. If necessary, have tires balanced and rotated at a tire shop.

Tools Required:

None (performed by tire technician)
