In this tutorial we’ll learn how to install Tektro Auriga Comp Disc Brakes. We’ll be covering other brands in future tutorials.

What You’ll Need

For this job you will need 2, 4 and 5mm allen wrenches and a T25 torx wrench. Your bike will also need to have compatible disc brake mounts on both the hubs and frame and fork.

Rotor Installation

First you’ll have to remove the wheel from the bike. Attach the rotor to the hub using the supplied bolts, making sure the rotation direction of the disc is installed in the same direction of the forward wheel movement. Tighten all 6 bolts with your T25 torx wrench until they are snug but not fully tightened. Then fully tighten the bolts in the following pattern until all are equally tightened to 4-6Nm.

Lever Installation

Place the brake lever with the half clamp on the handlebars, with the hose facing toward the center of the handlebars. Tighten the brake lever clamp in the desired position with a 4mm allen bolt. Tighten these bolts to 5-7Nm. If needed, adjust the brake lever reach closer to the handle bars with a 2mm allen wrench.

Caliper Installation

Before installing the disc caliper adapters, make sure your wheel axle is fully seated in the dropouts with the brake rotor on the caliper mounting side. Mount the adapter with the engraved F or R facing towards the axle as shown. Tighten the adapter bolts to 6-8Nm of torque.

Make sure the pads are correctly positioned in the caliper, then place the caliper over the rotor with the bleed screw facing away from the wheel. Attach the caliper to the adapter using the supplied allen bolts. Loosely tighten the bolts so you can still move the caliper.

Pad Adjustment

With the caliper mounting bolts loose, fully depress the brake lever and keep the lever depressed so the caliper correctly centers itself on the rotor. With the brake lever depressed, tighten the caliper mounting bolts to 6-8Nm. Use a zip tie to fasten the brake hose to ensure it is out of the way.

In our next tutorial we will cover how to bleed the brake lines on this model.
