3. Adjusting Rim Brakes
If you have rim brakes on your bicycle, follow these steps to adjust them properly:
3.1 Center the brake pads
Start by centering the brake pads so that they are equidistant from the rim. Use an Allen wrench to loosen the bolt that attaches the brake pad to the brake arm, move the pad as needed, and then tighten the bolt again.
3.2 Align the brake pads with the rim
Ensure the brake pads are aligned with the rim’s braking surface. The pads should make even contact with the rim when the brakes are engaged. Adjust as necessary using an Allen wrench.
3.3 Adjust the brake cable tension
If the brake cable tension is too loose, the brakes may feel unresponsive. If it’s too tight, the pads may rub against the rim even when not engaged. Use a 5mm Allen wrench to adjust the barrel adjuster on the brake lever until the desired tension is achieved.
3.4 Test the brakes
Before riding, always test your brakes by squeezing the brake levers to ensure they engage smoothly and provide sufficient stopping power. Make any final adjustments if necessary.
4. Adjusting Disc Brakes
For bicycles equipped with disc brakes, here’s how you can adjust them properly:
4.1 Check rotor alignment
Inspect the rotor and ensure it is aligned with the brake caliper. If the rotor is rubbing against the caliper or causing excessive noise, you may need to realign it. Loosen the mounting bolts, align the rotor, and then tighten the bolts back up.
4.2 Adjust the brake caliper position
Using an Allen wrench, loosen the bolts that secure the brake caliper to the frame or fork. Center the caliper over the rotor, aligning the pads with the rotor. Once aligned, tighten the bolts back up.
4.3 Adjust the brake pads
Check the clearance between the brake pads and the rotor. They should be close to the rotor without actually touching it. If the pads are too far away or rubbing against the rotor, make the necessary adjustments using the pad adjustment knobs or a 2.5mm Allen wrench.
4.4 Test the brakes
After making any adjustments, it’s important to test the brakes thoroughly. Squeeze the brake levers to ensure the pads engage the rotor smoothly and provide enough stopping power. Make any final adjustments if needed.

5. Replacing Brake Pads
If your brake pads are worn out or damaged, it’s time to replace them. Here’s a step-by-step guide on how to do it:
5.1 Remove the old brake pads
Using an Allen wrench, loosen the bolt that holds the brake pad to the brake arm. Once loose, slide the old pad out from its holder. Repeat the process for the other pad.
5.2 Install new brake pads
Take the new brake pads and insert them into the pad holders. Make sure they are securely seated and aligned with the rim or rotor.
5.3 Align the pads with the rim/disc
Ensure the pads are evenly aligned with the rim or rotor. Adjust their position if necessary by loosening the mounting bolts and sliding the pads as needed. Once aligned, tighten the bolts securely.
6. Replacing Brake Cables
If your brake cables are frayed or damaged, it’s best to replace them. Here’s how:
6.1 Remove the old brake cables
Start by loosening the clamp bolt that holds the brake cable to the brake caliper. Then, release the cable from the brake lever by loosening the barrel adjuster or removing it altogether. Once loose, remove the cable from its housing.
6.2 Install new brake cables
Take the new brake cable and insert it into the housing, ensuring it follows the same path as the old cable. Thread the cable through the barrel adjuster and secure it to the brake caliper using the clamp bolt. At the other end, attach the cable to the brake lever, making sure it is properly seated.
6.3 Adjust cable tension
Using the barrel adjuster on the brake lever, fine-tune the brake cable tension. You want a small amount of slack in the cable when the lever is released, but not too loose. Test the brakes to ensure they engage smoothly before riding.
