•Allow brakes to cool before inspecting to avoid burns.

Symptoms

•Uneven brake wear on the pads
•Car pulls to one side during braking
•Grinding or squealing noises when brakes are applied
•Brake fluid leaks around the caliper
•Reduced braking efficiency or a spongy brake pedal
•Overheating of the wheel hub or brake components

Diagnostic Steps

1
Inspect brake pads for uneven wear patterns.
2
Check for fluid leaks around the caliper and brake lines.
3
Perform a visual inspection of the caliper for signs of rust or damage.
4
Test the brake pedal feel for sponginess or excessive travel.
5
Observe the vehicle's behavior during braking to identify pulling or vibrations.
6
Use a temperature gun to measure the brake caliper temperature after driving to check for overheating.

Solution

Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and secure it with wheel chocks.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Clean

Inspect the caliper for any visible damage or rust.
Clean the caliper and surrounding components using brake cleaner.
Check the brake pads for proper thickness; replace if worn below specifications.

3. Replace the Brake Caliper (if necessary)

Tools Required: Socket set, brake caliper tool, torque wrench, brake line wrench.
Disconnect the brake line from the caliper using a brake line wrench to avoid damaging the fitting.
Remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the rotor and check the condition of the caliper piston.
Install the new caliper by reversing the removal steps, ensuring the mounting bolts are torqued to manufacturer specifications (typically 25-35 Nm).
Reconnect the brake line and ensure there are no leaks.

4. Reassemble and Bleed Brakes

Reinstall the brake pads and ensure they are seated correctly.
Reattach the wheel and lower the vehicle.
Bleed the brake system to remove any air, using a brake bleeder kit; follow a wheel sequence (usually from the farthest wheel to the nearest).
Ensure the brake fluid level in the master cylinder is adequate.
