Bicycle Brakes Will not Launch? Widespread Issues And Straightforward Options

Caught brakes could be actually irritating. What do you do when a brake fails to carry out the one job that it’s designed for? Wait! There are different options than kicking and screaming at your brake as a result of that can definitely not assist. 

The most typical explanation for a brake that received’t launch is Brake Cable Rigidity. It additionally is likely to be as a result of motive that you’ve Misaligned Brake Calipers or your brake elements are Rusted. Hydraulic brakes don’t work as a result of there is likely to be a Brake Fluid Subject or Piston Contamination. No matter could be the motive, there’s a resolution for it if it’s not too late. 

Causes Why Your Brake Is Caught 

These are the commonest explanation why your brake is caught in accordance with your brake kind. I’ve additionally talked about downside indicators so you’ll be able to simply determine if that is the issue that it is advisable to work on.

Widespread Brake Issues In accordance To Brake Varieties

Brake Sort Functioning Brake Issues
Caliper Brakes Mounts Above The Wheel On A Single Level  Brake Cable Rigidity, Brake Pad Put on And Contamination
Disc Brakes Makes use of a Stainless Metal Cable To Set off the Piston Which Creates Friction Brake Cable Rigidity, Brake Pad Put on, Rotor Contamination
Hydraulic Disc Brakes Makes use of Brake Fluid  Brake Pad Put on, Brake Fluid Points
Cantilever Brakes Every Arm Of The Brake Is Hooked up To A Pivot Level On Facet Of Seat Keep Or Fork  Brake Cable Rigidity, Spring Rigidity
V Brakes (Linear-Pull) Related To Cantilever Brakes With Longer Brake Arms  Brake Cable Rigidity, Brake Pad Alignment

1. Brake Cable Rigidity 

It’s attainable that you simply don’t have the required brake desk rigidity. When these cables will not be correctly adjusted, it could possibly result in them being stretched. This causes an extra rigidity on the brake cable which prevents the brake from releasing correctly. That is additionally a typical downside.

A standard indicator of this downside is a stiff brake lever really feel. I additionally preserve a watch out if there’s an inadequate brake pad retraction from the rim. That is additionally an indicator of excessive brake cable rigidity.

2. A Contaminated Brake Pad 

Brake pads are susceptible to all of the mud and particles on the market. They’ll simply accumulate all of the dust, particles, and even the extreme oil that you simply use. This results in a lack of grip that the pads have on the rim. You would possibly hear a squealing sound once you use the brakes. That is one other explanation for diminished brake effectiveness.

Checking Bicycle Breaks

3. Over-Used Brake Pad 

The brake pad rubs in opposition to the edges which causes friction. With time, this friction can result in the brake pads carrying down. When this occurs your brake efficiency will cut back resulting in a caught brake. To determine in case your brake pad is worn out, you’ll have to look at the thickness of your pad. It is a widespread downside you’ll be able to face on mechanical, disc, and hydraulic disc brakes. 

4. Rotor Contamination 

Just like the brake pad, a rotor can be very susceptible to mud and different particles. These particles can contaminate the rotor which impacts the efficiency. Because of this, your brakes will be unable to launch correctly. For those who hear noises whereas braking, it is best to verify the floor of your rotor. Search for any discoloration or mud which may have gathered there. 

5. Brake Fluid Issues (Hydraulic Disc Brakes)

Hydraulic brakes use brake fluid for the switch of strain to generate the controlling mechanism required for braking. Air can simply infuse within the fluid if you’re utilizing worn-out brake pads. Air can even make its approach contained in the fluid if in case you have an issue along with your calipers or your piston. When this occurs, the air bubbles could cause a leak which can have an effect on your braking efficiency. 

6. Spring Rigidity 

Cantilever brakes have springs. These springs management the motion of the brokes. If there’s any harm to the springs or they’re misaligned, your brake efficiency will probably be affected. To determine a spring rigidity downside, you’ll have to examine your brake arms. Launch the brake lever and see in the event that they return to their open place. 

7. Brake Pad Alignment 

It’s attainable that the brake pad isn’t correctly aligned. A misaligned brake pad could have uneven contact with the bike rim. It will result in an improper brake launch or your brake won’t launch in any respect. Maintain an in depth eye in your rim. Whenever you squeeze your brake lever, one of many pads will rub in opposition to the rim, and the opposite is not going to.

How To Repair A Brake That Received’t Launch 

It’s not very troublesome to repair brakes that received’t launch but it surely’s solely attainable if in case you have a scientific method.

Brake Sort Brake Issues Resolution
Caliper Brakes Brake Cable Rigidity, Brake Pad Put on And Contamination
  • Verify and modify cable rigidity for clean operation.
  • Examine brake pads and exchange worn or contaminated ones.
Disc Brakes Brake Cable Rigidity, Brake Pad Put on, Rotor Contamination
  • Alter cable rigidity for exact braking response.
  • Change worn brake pads and clear rotor for optimum grip.
Hydraulic Disc Brakes Brake Pad Put on, Brake Fluid Points
  • Change worn brake pads with manufacturer-recommended ones.
  • Examine and handle any brake fluid leaks or air bubbles.
Cantilever Brakes Brake Cable Rigidity, Spring Rigidity
  • Alter cable rigidity for correct brake engagement.
  • Examine and modify spring rigidity for constant braking.
V Brakes (Linear-Pull) Brake Cable Rigidity, Brake Pad Alignment
  • Verify and modify cable rigidity for clean operation.
  • Guarantee correct alignment of brake pads for even contact with the rim.

1. Alter Cable Rigidity 

First, verify your cable rigidity. Whether it is excessive modify the brake cable rigidity. You will need to have a well-adjusted cable. Whether it is free, you’ll really feel that your brakes are sluggish. If the cable is overly tight, your brakes will really feel stiff. Use a barrel adjuster or a cable anchor bolt close to your caliper to fine-tune the stress.

2. Examine The Brake Pads

The following step is to examine your brake pads. Brake pads are susceptible to put on and tear due to the friction attributable to the rim’s braking floor. They’re additionally susceptible to mud and particles. You may know that your brake pads are excessively worn out if the thickness is lower than 1-2mm. If see, it’s important to exchange them.

Clear the rim braking floor in order that the pads can have interaction simply. I usually use sandpaper to take away any contaminants that is likely to be sticking there. You need to use a cleaner or a light abrasive. 

3. Repair The Alignment 

For those who don’t have this concern, it’s important to verify the alignment of your brake arms and the calipers. This typically occurs when one brake pad is in higher contact as in comparison with the opposite one. In case your brake arms will not be in parallel with the braking floor of the rim, it’s important to modify the caliper-positioning. 

Lose the mounting bolt after which realign your brake caliper. After you have realigned it, tighten the bolt in order that the place is secured.

4. Common Bleeding ( Hydraulic Brakes)

In case you have hydraulic brakes, it’s attainable that you’ve points with the brake fluid. First, examine the extent. For those who discover that the extent is low, it could be as a result of there’s a leak. You may bleed your brake system to verify there are not any air bubbles. Be very cautious and observe the producer’s directions. I observe this methodology as a result of it is vitally efficient: 

5. Cable Lubrication (V-Brakes)

Whenever you lubricate the brake cables, it makes certain that the friction is minimized. It additionally ensures that your brakes are functioning effectively. You need to use an appropriate cable lubricant. I exploit Tri-flow. It’s simply out there in lots of bike retailers. Simply make certain to shake the bottle properly earlier than you employ it and wipe off if there’s any extra. 

6. Alter The Spring Rigidity 

Verify your spring rigidity earlier than each trip. In v-brakes, these springs are very important in controlling the actions of the brakes. Whether it is excessive or low, you will want to regulate it so you will get the precise steadiness. 

7. Examine The Elements 

V-brakes have small elements however they’re very important in attaining efficient efficiency of the brakes. An important of all is the noodle and the boot. The noodle is that curved steel piece that holds your cable. The rubber boot is positioned at your brake arms. They’re extra susceptible to wreck.

More often than not, there was an issue with my noodle or the boot and I didn’t actually know this within the begin. I’d spend hours watching movies, attempting to know what was fallacious with my brake till my buddy recommended I examine the noodle. That’s after I realized the place the issue was. I changed the noodle and my brake was working once more. 

8. Clear The Rim Floor (V-Brakes)

If the rim floor isn’t, your v-brakes is not going to carry out. They require a clear floor for efficient functioning. Clear the rim at intervals so as to have dependable braking. I exploit surgical spirit (rubbing alcohol) and a rag to scrub my rim floor. Take a small spray bottle and spray the spirit onto your rim floor. Spray it on either side after which gently wipe it with the rag. You may simply discover the surgical spirit at pharmacies.

9. Tighten The Bolts And Fasteners

On a V-brake system, you’ll have bolts and fasteners. Bolts maintain collectively the brake arms, posts, and cable anchor. Tighten these bolts securely. For caliper brakes, cantilever brakes, and disc brakes, there are particular bolts and fasteners that it’s important to examine and tighten routinely. These embody mounting bolts, completely different connecting factors within the brake system in addition to the rotor bolts discovered on disc brakes. 

10. Take A Check Drive 

In case you have fastened the issue along with your bike brake. I’d advocate to check drive first earlier than heading out for the day. Be certain to check drive in a protected setting. Verify that your brake lever is clean. You also needs to have a look at the brake pads. If they’re making even contact with the rim once you have interaction the brake, you’re good to go. 


Why received’t my bike brake lever squeeze?

Your brake lever received’t launch since you may need an improper cable rigidity. One more reason for this concern is brake pad put on, poor alignment, contamination, a mechanical concern, or a brake fluid downside for hydraulic brakes. 

Can I exploit wd40 on seized brakes?

Sure however solely utilizing wd40 on seized brakes is not going to remedy your downside. You must determine the difficulty after which handle it correctly to make it possible for your brakes work. 


It may be actually irritating when your brakes make it inconceivable to regulate the pace in accordance with your using wants. A dysfunctional brake is a menace to your security. That’s why it is best to take out time to correctly examine the difficulty and handle it as quickly as attainable.
