How To Adjust, Clean & Maintain Your Braking Systems

Reliable braking is non-negotiable. Whether you’re bombing descents or commuting through traffic, your brakes should feel consistent, responsive, and quiet. Here’s how to keep them that way.

1. Identify Your System

Most modern bikes use disc brakes, while older or lightweight road bikes may rely on rim brakes. The steps below focus on disc systems—the performance standard for today’s riders.

2. Inspect the Pads

Worn pads reduce stopping power and can damage rotors.

• Check Thickness: Replace if pad material is under 1.5 mm.

• Clean Rotors: Spray Finish Line® Disc Brake Cleaner to remove contaminants and restore bite. Wipe with a clean, lint-free cloth.

3. Align the Caliper

Misalignment causes uneven braking and unwanted noise.

• Loosen the caliper bolts.

• Squeeze the brake lever to center the caliper over the rotor.

• Retighten evenly. Spin the wheel—if it spins freely and stops smoothly, you’re dialed in.

4. Adjust Lever Reach

Your brakes should feel natural under your fingers. Use the reach adjust screw near the lever pivot to fine-tune lever distance for comfort and control.

5. Bleed the Brakes (When Needed)

If your lever feels spongy, there’s air in the system. Bleeding restores a firm, consistent feel.

• Use the Correct Fluid:

• Finish Line® Mineral Oil for mineral oil systems.

• Finish Line® DOT 5.1 Brake Fluid for DOT-based systems.

• Secure the bike with the lever higher than the caliper.

• Attach your bleed kit and flush the system until clean fluid appears.

• Test for firmness and even pressure.

6. Test & Tune

After adjustments, check braking response on a flat, safe surface. Fine-tune lever reach or caliper alignment as needed.

Brake Maintenance Tips

• Clean rotors regularly with Disc Brake Cleaner—especially after rain or mud.

• Replace brake fluid annually for consistent performance.

• Inspect pads and rotors for wear every few weeks if you ride often.
