Possible Causes:
- Brake fluid leak
- Faulty brake master cylinder
- Faulty brake booster
- Faulty brake caliper or wheel cylinder
Quick Troubleshooting Tips:
1. Check the brake fluid level in the master cylinder. If it is low, fill it up and try bleeding the brakes.
2. Inspect the brake lines and connections for any leaks. If you find a leak, repair it and bleed the brakes.
3. Test the brake booster by pressing on the brake pedal. If it feels spongy or goes all the way to the floor, the booster may be faulty and needs to be replaced.
4. Check the brake calipers and wheel cylinders for proper operation. If they are not functioning properly, they will need to be replaced.
Long-Term Solution:
If you have tried all of the above and are still experiencing no brake pressure, you should have your vehicle towed to a qualified mechanic for diagnosis and repair.
