- In this and the following pages we will show you how to replace the brake hoses in different makes and models, we will document these jobs as we get vehicles in our shop that need the brake hoses replaced.
- As you know the brake hoses in your vehicle carry the fluid to the brake calipers if they have disc brakes, or the wheel cylinders if the car still has drum brakes.
The brake hoses are made from flexible material at difference to the brake lines, the reason why the brake hoses are flexible is because since the calipers are attached to the wheels, they move up and down constantly as the suspension of your vehicle does its job when you travel on uneven surfaces, not to mention that they also have to be long enough to extend when you steer the vehicle.
- The first hose we are going to illustrate was removed from a 1998 Ford F-150 pick-up 2wd, it was the right front brake hose. Please note that this procedure applies to most makes and models, even though their design may vary slightly, nevertheless, we will illustrate other vehicles as we get them in our shop.
- To perform this job you will need to lift the front end of the vehicle, secure it on jack stands, making sure that the parking brake is set and the rear wheels are secured with wheel chucks, next proceed to remove the wheel of the car that has the bad brake hose.
- Once the wheel is off, proceed to remove the bolt that attach's the brake hose to the brake caliper, making sure that you have a drip pan to collect the brake fluid that will be lost during this procedure.
- Next proceed to loosen the nut that attach's the brake hose and the steel brake line together, if necessary, use a back up wrench on the other end.
- Remove the bolt that secures the brake hose's bracket to the frame of the vehicle, remove the hose.
- Install the new brake hose in the reverse order you took the old one off, but make sure that you install new copper washers in the bolt that attachés the hose to the brake caliper, make sure that the bolt is tight to avoid brake fluid leaks
- The final step is to bleed the air out of the system, if you don't have a vacuum brake bleeder like ours, you can have an assistant help you bleed the air out, if you don't know how, this is the procedure:
1- Have your assistant push the brake pedal all the way to the floor and hold it there, next you open the bleeder in the brake caliper to allow brake fluid and air out, if you have access to a clear hose, attach it to the bleeder, it makes the job easier because you can see the air bobbles exciting the system and it allows you to collect the brake fluid in a container instead of making a moss on the floor.
2- Close the bleeder, and ask your assistant to let the brake pedal out.
3- Have him or her pump the brakes a couple times, and hold the pedal to the floor and do it again till you don't have any air coming out.
NOTE: You will need to bleed the air on the other front wheel also because it is very likely that since they share the same hydraulic channel, the other wheel will have air in it also.
