⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the brakes to cool before inspection or replacement to avoid burns.

Symptoms

•Vehicle shakes or vibrates when braking
•Steering wheel may also shake during braking
•Increased stopping distance
•Possible noise from the brakes (squeaking or grinding)
•Brake pedal pulsation or vibration

Diagnostic Steps

1
Inspect brake pads for uneven wear or damage.
2
Check rotors for warping or thickness variation using a micrometer.
3
Examine wheel bearings for play or wear.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.
Disconnect the battery to ensure safety during repairs.

2. Brake Pad Inspection

Remove the wheel using a socket set.
Inspect brake pads for uneven wear; replace if necessary.
Tools Required: Socket set, brake pad spreader.

3. Rotor Inspection

Use a micrometer to measure rotor thickness at multiple points.
Check for warping by visually inspecting for uneven surfaces or using a dial indicator.
If warped beyond specifications, replace rotors.
Torque Values: Install new rotors to manufacturer specifications (usually around 80-100 ft-lbs depending on model).

4. Wheel Bearing and Suspension Check

Remove the brake caliper and rotor to access wheel bearings.
Check for play in the wheel bearing by wiggling the wheel; replace if excessive movement is detected.
Inspect control arms, tie rods, and bushings for signs of damage or excessive wear; replace if necessary.

5. Tire Balance and Alignment

Take the vehicle to a tire shop for balancing and alignment checks.
Ensure all tires are inflated to the recommended pressure.
