Undoubtedly, there is a reason why hydraulic disc brakes are increasingly becoming popular.

Unlike the traditional rim brakes, disc brakes have remarkable stopping power in mud, rain, and snow. Also, the hydraulic disc brakes can be used with any tire width.

And because they use the fluid as opposed to a cable pulling system, hydraulic disc brakes tend to offer fast and efficient braking.

However, like any other brake type, once installed, you`ll need to adjust them accordingly to ensure they`re set up properly and to your riding preference.

In this article, we shall explore everything you need to know how to adjust your hydraulic disc brakes on your bike.


Step 1

First off, mount your bike on a stand. This will make the disc brake adjustment an easy affair.

 Step 2

The next step is to check on the brake lever.

The hydraulic disc brake on many road bicycles is positioned on the handlebar similar to conventional or the non-hydraulic bikes.

We have covered how to adjust other types of bicycle brakes.

When setting the brake lever, ensure that you place it horizontal to the handlebar, within an easy to reach position.

However, according to Telegraph UK, you should avoid tweaking the lever in a crash. Instead, you should rotate it down, and adjust it behind the lever pivot. This is to mean the brake lever should not be level with your handlebar but just below it.

To do this, you`ll need to use a hex wrench to loosen the bolts as you move the brake levers closer to the handlebars and the proper position.

Step 3

The next crucial step after positioning the brake levers is to align the calipers.

It`s essential that your disc brakes have properly aligned calipers, and this will avoid the calipers from hitting the spinning rotor.

Remember that when the caliper hits the spinning rotor, it causes drag and this could impede your performance.

Fortunately, it`s easy to recognize this defect since its often accompanied by a howling or rubbing sound when the caliper alignment is off.

Step 4

However, for any disc brake system, especially the hydraulic disc braking, it`s difficult to view the pad to rotor alignment.

Therefore, while spinning, ensure that you place a white paper or white rage behind the area of your viewing.

As you spin the wheel, pay focus on how the rotor is spinning in between the calipers.

Ideally, it should be aligned exactly at the center.

In the event you find it rubbing, loosen the two centering bolts that are holding the caliper to the mounting bracket by use of a hex.

If you`re having trouble centering the rotor, you can try slipping a thin business car in between the pads.

Step 5

Pull the brake lever gradually, and tighten the bolts.

Step 6

To confirm whether the rotor is aligned properly and not rubbing, spin the wheel and the eye disc.

Step 7

The final step is to take your bike for a test spin.

Gradually apply the brakes several times to break the rotors.

Check whether all the braking components are in position and that your bike is braking efficiently.
