⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted and supported before working underneath it.
•Wear safety goggles and gloves to protect against debris and sharp components.

Symptoms

•Vehicle shakes or vibrates when applying brakes
•Steering wheel may shake during braking
•Pulsation felt in the brake pedal
•Possible squeaking or grinding noise when braking
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect brake rotors for warping by measuring thickness and runout.
2
Check brake pads for uneven wear or damage.
3
Examine suspension components for wear or looseness (tie rods, control arms).
4
Inspect wheel alignment and balance.
5
Verify that calipers are functioning properly and not sticking.
6
Check for any loose components in the brake system.

Solution

Diagnostic Steps

1
Inspect brake rotors for warping by measuring thickness and runout.
2
Check brake pads for uneven wear or damage.
3

4
Inspect wheel alignment and balance.

Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery if necessary for electrical safety.

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Components

a. Inspect Brake Rotors

Measure rotor thickness with a micrometer.
If warped (more than 0.002 inches runout), replace rotors.

b. Replace Brake Pads

Remove caliper bolts with a socket wrench.
Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove old brake pads and replace with new ones. Ensure they are oriented correctly.

4. Reassemble Components

Reinstall the caliper and torque bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reattach the wheel and torque lug nuts in a crisscross pattern to specifications (typically 80-100 ft-lbs).

5. Perform Brake Bedding Process

After reassembly, perform a brake bedding procedure according to the manufacturer’s guidelines to ensure effective braking performance.
