⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on brake systems to avoid electrical accidents.
•Allow the brake components to cool before handling to prevent burns.

Symptoms

•Brake pedal feels stiff or unresponsive
•Vehicle pulls to one side during braking
•Increased brake noise (squealing or grinding)
•Brake pads wear unevenly
•Wheel temperature is noticeably higher than others after driving
•Warning light for the brake system may illuminate

Diagnostic Steps

1
Inspect the brake caliper visually for signs of corrosion or damage.
2
Check brake fluid level and condition in the master cylinder reservoir.
3
Remove the wheel and check for any physical obstruction or debris affecting the caliper.
4
Test the caliper piston movement by applying and releasing the brake pedal.
5
Inspect brake lines for kinks or blockages that may restrict fluid flow to the caliper.
6
Measure the temperature of each wheel after a short drive to determine if one caliper is overheating.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, C-clamp, socket set, torque wrench, brake lubricant, protective gloves, safety goggles.
Raise the vehicle using a jack and secure it with jack stands. Remove the wheel using a lug wrench.

2. Remove Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using a socket set.
2. Carefully slide the caliper off the brake rotor. Support it to avoid straining the brake line.
3. Disconnect the brake line from the caliper if necessary (use a wrench and be prepared for brake fluid leakage).

3. Inspect and Clean

Sub-steps:
1. Inspect the caliper for damage, corrosion, or wear.
2. Clean the caliper using brake cleaner to remove dust and debris.
3. Check the caliper slide pins; if they are rusted or stuck, remove them and clean thoroughly or replace as necessary.

4. Replace or Repair Components

Sub-steps:
1. If the piston is stuck, use a C-clamp to carefully push it back into the caliper housing.
2. If it does not move freely, consider replacing the caliper.
3. Replace any worn brake pads and check the rotor for damage; replace if necessary.

5. Reassemble and Reinstall

Sub-steps:
1. Apply brake lubricant to the slide pins and reinstall them in the caliper.
2. Reconnect the brake line to the caliper, ensuring it's secured properly.
3. Slide the caliper back onto the rotor and tighten the mounting bolts to the manufacturer’s specified torque.

6. Final Checks

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Pump the brake pedal several times to seat the pads against the rotor.
3. Check brake fluid levels and top off as necessary.
