Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system to avoid accidental activation.
•Allow the vehicle to cool before working on brake components to prevent burns.

Symptoms

•Squeaking or grinding noise when braking
•Vibration in the brake pedal during braking
•Decreased braking efficiency
•Warning light on the dashboard (if applicable)
•Visible wear on brake pads or rotors

Diagnostic Steps

1
Inspect the rear brake pads for wear and thickness.
2
Check the rear brake rotors for any signs of scoring or warping.
3
Listen for noise while driving at low speeds to determine if it occurs only during braking.
4
Examine the brake calipers for proper operation and signs of sticking or misalignment.
5
Inspect the brake hardware (shims, clips, etc.) for damage or corrosion.

Solution

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Safely elevate the vehicle using a jack and secure it with jack stands.
Remove the rear wheels using a lug wrench.

2. Remove Brake Components

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper off the rotor and support it using a bungee cord to avoid stress on the brake line.
3. Remove the brake pads from the caliper bracket.

3. Inspect and Replace Components

Sub-steps:
1. Examine the brake pads; if they are worn down to the indicators, replace them.
2. Check the rotors for wear; if they are below the minimum thickness or have deep grooves, replace them.
3. If necessary, use a brake lathe to resurface rotors that are within specifications but have minor imperfections.

4. Clean and Reassemble

Sub-steps:
1. Clean the caliper bracket and rotor with brake cleaner to remove dust and debris.
2. Install new brake pads into the caliper bracket.
3. Reinstall the caliper over the new pads and secure with caliper bolts, tightening to manufacturer specifications (typically around 20-30 ft-lbs).

5. Reinstall Wheels and Lower Vehicle

Sub-steps:
1. Put the rear wheels back on and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and remove the jack.
3. Torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).
