⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the brakes to cool before handling to avoid burns.
•Always wear safety glasses while working with power tools.

Symptoms

•Shaking or vibration in the steering wheel during hard braking
•Pulsating brake pedal
•Increased stopping distance
•Noise such as grinding or squeaking when braking
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a caliper gauge.
2
Check brake rotors for warping or uneven surfaces using a dial indicator.
3
Examine suspension components, including tie rods and control arms, for wear or damage.
4
Test brake calipers for proper operation and ensure they are not sticking.
5
Check tire balance and alignment to rule out other causes of vibration.
6
Inspect wheel bearings for play or wear.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lift it using a jack and jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and secure it to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are properly aligned.
Tools Required: Socket set, brake cleaner, caliper tool.

3. Check and Resurface or Replace Rotors

Sub-steps:
1. Measure the rotor thickness with a micrometer; if below the minimum specification, replace the rotor.
2. If rotors are within specification, use a brake lathe to resurface them to ensure a flat surface.
3. Clean the rotors with brake cleaner before reinstallation.
Tools Required: Micrometer, brake lathe, brake cleaner.
Safety Warning: Always wear safety glasses while working with power tools.

4. Inspect Suspension Components

Sub-steps:
1. Check for play in the tie rods and ball joints by shaking the wheel.
2. Replace any worn components as necessary to restore proper handling and alignment.
Tools Required: Wrench set, torque wrench.

5. Reassemble and Test

Sub-steps:
1. Reinstall the caliper and tighten bolts to the manufacturer's specifications.
2. Reattach the wheel and lower the vehicle.
3. Pump the brakes to ensure proper contact before test driving.
Tools Required: Torque wrench.
