If you are experiencing noisy brakes on your SUPER73, you may need to bed-in your brakes, re-align your brake calipers, treat your pads and rotors for contamination, or replace your pads and rotors.  Follow the steps outlined below to complete these maintenance procedures on your brake system.

Due to the sensitive and critical nature of the brake system, we would recommend you take your bike to a local mechanic if you believe this service is beyond your skillset or if you are not comfortable performing the work. 

SUPER73 will not be held liable for any damages that occur due to the improper handling of the bike.

The video below goes in-depth into brake maintenance for both mechanical and hydraulic brakes, including pad and rotor replacement steps.

New Brake Pad & Rotor Bed-In Process

Any time you replace your brake pads, rotors, or both, it is important they are properly bedded for optimal performance. To bed your brakes properly after replacement, accelerate your bike up to 20mph and then engage your brakes to bring the bike to a near stop. Repeat the process up to 8-10 times. This process allows your pads to wear evenly and removes surface glaze and contamination from installation.

Brake Caliper Alignment

Over time, your brake calipers can get out of alignment and will cause the pads to rub unevenly on your rotors, which can contribute to noisy brake symptoms.  To re-align your calipers, you will need a 5mm hex key.

1. With a 5mm hex key, loosen the two caliper bolts on its bracket. Do not remove the caliper. The bolts are located on the top and bottom of each brake caliper.
2. With the caliper loose, compress its brake lever. This will allow the caliper to grab the rotor evenly and reposition itself on the bracket.
3. With the brake lever still compressed, tighten the caliper bolts.
4. Once the caliper bolts are tightened, you can release the lever, and your brake caliper will now be centered.

Brake Pad and Rotor Cleaning

If you are still experiencing noisy brakes after aligning the brake calipers, you may need to clean and sand down the brake pads and rotors to remove potential contamination. During this step you will also want to ensure the brake pads have at the bare minimum > 1mm pad material left. 

Since both your brake pads and rotors may be contaminated, they will need to be adequately cleaned. Simply using Windex will help! Windex is an excellent cleaning solution, thanks to its formulation with ammonia-D. 

You will need a 5mm hex key and a 3mm hex key. We also recommend Windex, Wet-Dry Extra Fine 200+ -Grit sandpaper, and a pair of gloves.

1. Loosen the bolts that mount the caliper on the bike using the 5mm hex key.
2. Loosen the retaining bolt that mounts the brake pads using the 3mm hex key.
3. Once you have successfully accessed the brake pads, you will need Wet-Dry Extra Fine 200+ -Grit sandpaper to sand the brake pads.
4. Do not get brake pads soaked due to their organic compound.
5. Using Windex, apply a few sprays on a clean & durable paper towel.

6. While wearing gloves, carefully decontaminate and thoroughly wipe down the (Silver) rotor with the Windex solution.

7. Repeat until the components are fully clean.

Also, ensure that the brake rotor isn’t warped. Spin the wheel and observe the rotor for any irregularities in its movement. If the rotor appears to have a wobble in it as it spins, it is warped and needs to be replaced to ensure proper brake performance.

If all of the above steps have been completed and you are still experiencing noisy brakes, we recommend replacing the brake pads and rotors.
