Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect and Clean the Brake Pedal Assembly

Remove any carpets or floor mats obstructing the brake pedal.
Visually inspect the pedal assembly for any obstructions or debris.
Use a cleaning solution and cloth to clean any sticky residue or dirt from the brake pedal and assembly.
Lubricate pivot points of the brake pedal with a suitable lubricant (e.g., silicone spray) to ensure smooth operation.

3. Check and Replace Brake Fluid

Remove the cap from the brake fluid reservoir and inspect the fluid.
If the fluid is dirty or contaminated, siphon out the old fluid using a brake fluid pump.
Refill the reservoir with fresh, manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4).
Bleed the brake lines to remove any air bubbles.

4. Inspect and Replace Brake Components

Remove the wheel and inspect the brake calipers, pads, and rotors for wear.
If the pads are worn down, replace them with new pads.
Inspect the rotors for scoring or warping; if damaged, replace the rotors.
Ensure all caliper bolts are torqued to manufacturer specifications when reassembling (typically 20-30 ft-lbs).

5. Test Brake Booster Operation

With the engine running, test the brake booster by pressing the brake pedal.
If the pedal does not sink slightly when the engine starts, the brake booster may be faulty and should be replaced.
