Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a level surface and securely supported by jack stands before starting work.
•Always disconnect the battery when working on brake components to prevent electrical issues.
•Allow brakes to cool before performing any inspections or repairs.

Symptoms

•Shaking or vibration felt in the steering wheel during braking
•Pulsation in the brake pedal
•Increased stopping distance
•Noise during braking (squeaking or grinding)
•Uneven wear on brake pads

Diagnostic Steps

1
Inspect the brake rotors visually for any signs of warping or surface irregularities.
2
Measure the rotor thickness using a micrometer to ensure they meet manufacturer specifications.
3
Check the brake pads for uneven wear or contamination.
4
Test drive the vehicle at various speeds to confirm the shaking occurs only during braking.
5
Use a dial indicator to measure rotor runout, ensuring it's within acceptable limits.

Solution

Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, micrometer, dial indicator.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported by jack stands before starting work.

2. Remove Wheel and Brake Components

Loosen lug nuts with a lug wrench while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Rotors

Inspect Rotors: Check the rotors for warping and thickness.
- If warped, proceed to replace.
Remove Rotors:
- Unscrew the caliper bracket bolts and carefully remove the caliper.
- Hang the caliper using a wire hanger or bungee cord to avoid strain on the brake line.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Position the new rotor onto the hub and secure it with retaining screws if applicable.

4. Reinstall Brake Components

Reinstall the caliper over the new rotor and tighten the caliper bracket bolts to manufacturer specifications (typically 25-35 ft-lbs).
Replace the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Finalize

Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).
Pump the brake pedal several times to seat the brake pads against the new rotors.
