Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the brake system.
•Ensure the vehicle is securely lifted and supported before working underneath.

Symptoms

•Pulsation or vibration felt through the brake pedal during braking
•Uneven brake wear on the rotors
•Noise during braking, such as grinding or squeaking
•Vehicle pulling to one side during braking
•Increased stopping distance

Diagnostic Steps

1
Inspect the brake rotors for warping or uneven wear.
2
Check brake pad thickness and condition for any signs of wear or damage.
3
Verify brake caliper operation by ensuring they move freely without sticking.
4
Measure rotor thickness to confirm it is within manufacturer specifications.
5
Use a dial indicator to check rotor runout for any deviations.

Solution

Diagnostic Steps

1
Inspect the brake rotors for warping or uneven wear.
2
Check brake pad thickness and condition for any signs of wear or damage.
3
Verify brake caliper operation by ensuring they move freely without sticking.
4
Measure rotor thickness to confirm it is within manufacturer specifications.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Remove Wheels

Tools Required: Socket set
Loosen the lug nuts on the front wheels slightly before raising the vehicle.
Once lifted, remove the lug nuts completely and take off the front wheels.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, rotor removal tool (if necessary)
Check the rotors for warping using a dial indicator.
If warped beyond specifications or damaged, proceed to replace:
1. Remove caliper bolts and slide the caliper off the rotor.
2. Hang the caliper using a bungee cord to avoid strain on the brake line.
3. Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
4. Install the new rotor, ensuring it is properly aligned.
5. Reinstall rotor screws if removed.

4. Inspect and Replace Brake Pads

Tools Required: C-clamp or brake caliper tool
Inspect the brake pads for wear; if they are worn down, replace them:
1. Remove the caliper bracket bolts and take off the caliper.
2. Remove the old brake pads from the caliper bracket.
3. Compress the caliper piston using a C-clamp or brake caliper tool to accommodate the new pads.
4. Install new brake pads into the caliper bracket.

5. Reassemble Brakes

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Tools Required: Torque wrench
Lower the vehicle and use a torque wrench to properly torque the lug nuts to the manufacturer’s specifications.
Repeat the process on the other side if necessary.
