How to Repair a Bike Brake
Whether you’re an avid mountain biker tearing through Buena Vista’s scenic trails or someone who enjoys quiet rides along the Arkansas River, there’s one thing every cyclist agrees on: your bike brakes must work perfectly. But what happens when they don’t? Don’t worry—you don’t have to be a professional mechanic to fix them. In this blog, we’ll walk you through how to repair a bike brake step by step. So, grab your tools, roll up your sleeves, and let’s get started!
Understanding Your Bike Brakes First
Before we jump into how to repair a bike brake, let’s get to know the basics. Most bikes in Buena Vista, CO, have either rim brakes or disc brakes.
Rim brakes: These squeeze the wheel’s rim to slow down.
Disc brakes: These use a rotor attached to the hub and are often more powerful and reliable.
Knowing which brake type your bike has is essential because the repair process differs slightly.
Step 1: Check What’s Wrong
The first step in how to repair a bike brake isn’t grabbing a wrench—it’s figuring out what’s actually wrong. Here’s what to look out for:
Is your brake lever too loose or too tight?
Are the brake pads worn out?
Do the brakes feel spongy?
Is there a squealing sound?
By identifying the problem, you’ll save time and know exactly what needs fixing.
Step 2: Tighten or Replace Brake Pads
Brake pads are often the culprit when your bike won’t stop properly. Here’s how to repair a bike brake when pads are the issue:
Inspect the pads: Check for wear. If the grooves are gone, replace them.
Align the pads: They should hit the rim squarely (for rim brakes) or the rotor (for disc brakes).
Adjust tension: Use a hex key to tighten or loosen the pad mounting bolt.
Don’t overtighten! You want the pads to move smoothly, not get stuck.
Step 3: Adjust the Brake Cable Tension
If your brakes feel loose, the cable tension might be too low. Here’s how to repair a bike brake by fixing the tension:
Find the barrel adjuster (usually near the brake lever).
Turn it clockwise to loosen or counterclockwise to tighten.
Test the lever until it feels firm but responsive.
Extra Insight: Sometimes, old cables stretch over time. If the barrel adjuster isn’t enough, you may need to pull the cable tighter from the brake caliper and secure it again.
Step 4: Bleed Hydraulic Disc Brakes
If you ride with hydraulic disc brakes and they feel spongy, air might be trapped in the brake line. Here’s a simplified version of how to repair a bike brake by bleeding:
Use a bleed kit: Buy one compatible with your brakes.
Remove the bleed screw: Attach the syringe filled with brake fluid.
Push fluid through: Until no air bubbles come out.
Tighten everything back and wipe excess fluid.

Step 5: Test Your Brakes
After you finish the repair, always test:
Squeeze the brake levers: They should feel firm.
Spin the wheel: It should stop quickly and smoothly.
Ride slowly in a safe area before hitting your favorite trail.
