Preparation:
1. Gather the necessary tools and materials, including new brake hoses, brake fluid, a flare nut wrench, a 10mm wrench, and a brake bleeder wrench.
2. Loosen the lug nuts on the front wheels but do not remove them completely.
3. Engage the parking brake.
4. Jack up the car and support it securely using jack stands.
Replacing the Brake Hoses:
1. Begin by removing the wheels to gain access to the brake calipers.
2. Locate the brake hose and identify the two nuts that connect it to the brake caliper and body.
3. Using the 10mm wrench, loosen the upper nut of the brake hose at the banjo bolt near the caliper.
4. Place a catch pan under the brake hose to collect any brake fluid that may leak out.
5. Using the flare nut wrench, loosen and remove the lower nut connecting the brake hose to the body.
6. Allow the remaining brake fluid to drain into the catch pan.
7. Remove the old brake hose by gently pulling it out of place.
8. Take note of how the old brake hose was routed as a reference for installing the new brake hose.
9. Install the new brake hose by positioning it in place and aligning the connection points.
10. Hand-tighten the upper and lower nuts of the brake hose to the banjo bolt and body, respectively.
11. Using the flare nut wrench, tighten the two nuts in a crisscross pattern to ensure an even seal.
Bleeding the Brake System:
1. Refill the brake fluid reservoir with the new brake fluid up to the recommended level.
2. Starting with the wheel located farthest from the master cylinder (often the rear passenger side), loosen the bleeder screw slightly with the bleeder wrench.
3. While slightly pressing the brake pedal, open the bleeder screw to allow any air bubbles trapped in the brake system to escape.
4. Continue pumping the brake pedal and opening the bleeder screw until brake fluid comes out without any bubbles.
5. Close the bleeder screw and move on to the next wheel, following the same procedure until all four wheels are bled.
Reassembly:
6. Reinstall the wheels and tighten the lug nuts properly.
7. Remove the jack stands and lower the car.
8. Test the brakes by applying gentle pressure to the brake pedal. Ensure that the pedal feels firm and responsive.
Remember to dispose of the old brake fluid and any other waste materials appropriately and to check the brake fluid level regularly to maintain optimal brake performance. If you are not comfortable performing brake repairs, it is recommended to seek assistance from a qualified mechanic.
