1. Tools and Materials Required:

To successfully remove and replace the hydraulic brake hose on your 1998 Blazer, you will need the following tools and materials:

- Jack and jack stands

- Lug wrench

- Brake fluid

- Wrench set

- Flare-nut wrench

- Brake bleeder kit

- Safety goggles

- Gloves

- Clean rags

Ensure you have all the necessary tools and materials before proceeding to the next section.

2. Preparing Your Vehicle for Brake Hose Replacement:

- Park your Blazer on a level surface and engage the parking brake.

- Locate the brake fluid reservoir under the hood. Remove the cap to relieve any pressure in the brake lines.

- Loosen the lug nuts on the tire of the corner where you will be replacing the brake hose.

3. Removing the Old Brake Hose:

- Using the jack, lift the vehicle off the ground and secure it with jack stands.

- Remove the lug nuts and take off the wheel, exposing the brake caliper.

- Locate the hydraulic brake hose attached to the caliper. Use a wrench or flare-nut wrench to disconnect the hose from the caliper.

- To prevent fluid leakage, place a clean rag under the connection point.

- Follow the brake hose along the vehicle's frame until you reach the point where it connects to the brake line. Using a wrench, loosen the brake line fitting and disconnect the brake hose.

4. Installing the New Brake Hose:

- Take the new hydraulic brake hose and attach it to the brake line, ensuring a tight connection.

- Follow the hose's path and connect it to the brake caliper, tightening it securely with the appropriate wrench.

- Double-check all connections to ensure they are tight and leak-free.

- Repeat the process on the other three wheels if necessary.

5. Bleeding the Brake System:

- Fill the brake fluid reservoir with new, clean brake fluid.

- Using a brake bleeder kit, start with the wheel farthest from the master cylinder (typically the rear passenger side).

- Locate the bleeder valve on the brake caliper and place a clear tube over it, leading it into a container to catch the old fluid.

- Have a partner press the brake pedal slowly and hold it down.

- Open the bleeder valve and allow fluid to flow until the old fluid is replaced with new, clean fluid.

- Close the bleeder valve and repeat the process for each wheel, working your way towards the front of the vehicle.

- Once all wheels have been bled, check the brake fluid level in the reservoir and top up if necessary.


Maintaining a properly functioning braking system is crucial for the safety of both you and your passengers. By following the step-by-step guide provided above, you can successfully remove and replace the hydraulic brake hose on your 1998 Blazer. Remember to exercise caution, wear appropriate safety gear, and always consult the vehicle's manufacturer or a qualified mechanic if you encounter any difficulties.
