Component
Brakes
Repair Time
2-4 hours

Safety Warnings

  • ⚠Always use gloves and goggles when working with brake fluid as it is corrosive.
  • ⚠Ensure the vehicle is securely lifted and supported with jack stands before working underneath.

Symptoms

  • •Soft or spongy brake pedal feel
  • •Longer stopping distances
  • •Brake warning light illuminated
  • •Increased pedal travel before brakes engage
  • •Possible fluid leakage under the vehicle
  • •Unusual noises when braking (e.g., squeaking or grinding)

Diagnostic Steps

  1. 1Inspect brake fluid level in the master cylinder reservoir.
  2. 2Check for air in the brake lines by performing a visual inspection and squeezing the brake lines.
  3. 3Inspect brake pads and rotors for wear and damage.
  4. 4Examine brake lines and hoses for leaks or cracks.
  5. 5Test the brake booster for proper operation by pressing the brake pedal several times to exhaust vacuum, then checking for hard pedal feel.
  6. 6Scan the vehicle for any diagnostic trouble codes (DTCs) related to the braking system.

Solution

Solution

1. Preparation

  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Wear safety gloves and goggles.

2. Inspect and Refill Brake Fluid

  • Open the hood and locate the brake fluid reservoir.
  • Check the fluid level; if low, add the recommended brake fluid type (DOT 3 or DOT 4).
  • Inspect the reservoir cap for any signs of damage or improper sealing.

3. Bleed Brake System

  • Tools Required: Brake bleeder kit or clear tubing and a catch bottle.
  • Start with the wheel farthest from the master cylinder (usually rear passenger side).
  • Attach the clear tubing to the bleeder valve on the brake caliper.
  • Have an assistant pump the brake pedal several times and hold it down.
  • Open the bleeder valve to release air and fluid, then close it before the pedal is released.
  • Repeat until no more air bubbles are visible in the tube.
  • Move to the next wheel in the order: rear driver side, front passenger side, and finally front driver side.

4. Inspect and Replace Brake Components (if necessary)

  • Tools Required: Socket set, torque wrench.
  • Remove the wheel and inspect brake pads for thickness; replace if less than 3mm.
  • Check rotors for scoring or warping; replace if necessary.
  • If brake pads or rotors are worn, remove the caliper by unbolting it and support it with a bungee cord (do not let it hang by the brake line).
  • Replace pads/rotors and reassemble the caliper, ensuring bolts are torqued to manufacturer specifications.

5. Recheck Brake System Functionality

  • After repairs, pump the brake pedal to restore pressure in the system.
  • Test drive the vehicle at low speeds to ensure proper brake engagement.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
  • Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

  • •Follow the manufacturer's recommended maintenance schedule
  • •Address warning signs early before they develop into major issues
  • •Use quality parts and fluids recommended for your vehicle
  • •Keep detailed records of all repairs and maintenance

Tools & Equipment Required

  • Brake bleeder kit or clear tubing
  • Socket set
  • Torque wrench

Parts Required

  • Brake fluid (DOT 3 or DOT 4)
  • Brake pads (if worn)
  • Brake rotors (if damaged)
