⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported before working underneath.
•Allow brakes to cool before inspection or handling components.

Symptoms

•Noticeable vibration in the brake pedal when braking
•Uneven brake wear observed upon inspection
•Increased stopping distance
•Brake warning light may illuminate
•Squeaking or grinding noises during braking

Diagnostic Steps

1
Inspect brake rotors for signs of warping or uneven wear.
2
Check brake pads for thickness and even wear patterns.
3
Measure rotor thickness using a micrometer to ensure it's within specifications.
4
Inspect brake calipers for proper function and signs of sticking.
5
Verify that brake fluid is at the correct level and in good condition.
6
Check for any air in the brake lines by performing a brake bleed if necessary.

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Use a jack and jack stands to lift the vehicle safely.

2. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel.
Inspect the brake components visually for any obvious damage or wear.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a micrometer to measure rotor thickness and check for warping using a dial indicator.
Replacement (if needed):
- Remove the caliper by unscrewing the caliper bolts with a socket wrench.
- Hang the caliper using a bungee cord to avoid straining the brake line.
- Remove the rotor by unscrewing any retaining screws or bolts and sliding it off the hub.
- Install new rotors (ensure they are clean and free from oil) and torque bolts to manufacturer specifications.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads according to the manufacturer’s guidelines and ensure they are properly seated.

5. Reassemble and Test

Reinstall the caliper over the new brake pads.
Torque caliper bolts to manufacturer specifications.
Reattach the wheel and torque lug nuts in a star pattern.
Lower the vehicle and pump the brake pedal to seat the pads.
