⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted on jack stands before working on brakes.
•Wear safety gloves and goggles.
•Always disconnect the negative battery terminal before working on brake components.
•Allow brake components to cool before inspection or handling.

Symptoms

•Unusual noises when braking (squeaking or grinding)
•Vehicle pulling to one side during braking
•Brake pedal feels spongy or goes to the floor
•Increased stopping distance
•Brake fluid leak around the caliper
•Overheating of brake components (foul smell)

Diagnostic Steps

1
Visual Inspection: Check for any visible signs of damage or leakage around the brake caliper and brake lines.
2
Check Brake Fluid Level: Inspect the brake fluid reservoir for low fluid levels which may indicate a leak.
3
Test Brake Operation: Perform a brake test to assess pedal feel and response.
4
Inspect Brake Pads: Remove the wheel and visually inspect the brake pads for uneven wear or damage.
5
Caliper Movement Test: Manually push the caliper piston back to see if it moves freely.
6
Check for Heat: After a short drive, carefully feel the temperature of the calipers to identify any that may be excessively hot.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, C-clamp, torque wrench, socket set.
Safety Warnings: Ensure the vehicle is securely lifted on jack stands before working on brakes. Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Caliper

Tools Required: Socket set.
Remove the bolts securing the caliper to the bracket.
Carefully slide the caliper off the brake pads, supporting it with a bungee cord or rope to avoid stress on the brake line.

4. Inspect and Clean

Inspect the caliper for any cracks or signs of leaking fluid.
Clean the caliper and surrounding area with brake cleaner.
Check the piston for functionality; if stuck, it may need replacement.

5. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they fit properly within the caliper.

6. Reinstall Caliper

Use a C-clamp to gently push the caliper piston back into the caliper housing to accommodate the new brake pads.
Reattach the caliper over the brake pads and secure it with the previously removed bolts.
Torque the caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).

7. Reassemble Wheel

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).
