With mechanical disc brakes, we adjust brakes if our brake lever pulls all the way into the handle bar. This guide will show how to adjust those brakes, specifically Tektro Aries MD-M300. However, this process should work with other mechanical brakes too. The process is quite easy and anyone can complete the guide without extensive knowledge of bicycles.

To center the caliper for a smooth breaking experience, loosen up the two bolts of the brake situated at top and at bottom.
The bolts that are being loosened in the picture are the wrong bolts for this adjustment. These bolts attach the brake assembly to the frame.
The adjustment bolts to keep the rotor centered between the disc pads have the heads facing up, and are just above the bolts pictured. The proper adjusting bolts allow the disc brake pads to move in the “cross bike” direction which is necessary for centering the rotor between the pads.

While putting the brake on, tighten up both the bolts.
The bolts you indicate for adjustment are caliper to frame mounting bolts, NOT ADJUSTING BOLTS.
The adjustment bolts are on top of the caliper mounting bracket.
Please revise.

Dude, the cable is attached incorrectly. The cable routes up and over the little arm.
I need a replacement t25 bolt and square ribbed nut that is shown in step 4. Any help would be stellar.
