how to tune your bicycle brakes to stop properly

by:JHY     2019-11-01
Adjust your bike brakes: this is one of the most common modes of transportation in the world.
People from all walks of life use this practical, simple, fun machine to walk around.
So why do few people know how to adjust the brakes?
It\'s not hard to learn how to adjust the bike brakes.
With a little time, the right tools and some knowledge
How, your bike will be smooth, safe and \"squeaky\" for free.
It is essential to adjust the bicycle brake correctly.
You don\'t want them to fail at the last minute.
A set of brakes can stop you well, which will inspire your confidence and you will ride more often.
You can pay extra at the local bike store, but why?
Anyone can manage the basic brake maintenance of the bike.
This article is intended as \"how\" to adjust the bike brake system \".
We will look at several of the most common mechanical braking systems on the market today and give the results of the operation
How they work. Let\'s begin!
Adjust the bike brakes: Before you start fiddling with the brakes, you need to determine what needs to be adjusted.
There may be some problems, but fortunately, it\'s easy for you to troubleshoot.
Here are some common problems and the root causes associated with them.
Question: the brakes on my bike squeak and it drives me crazy!
Reason: This is a very common thing, especially on old bikes, chrome (shiny)rims.
This is usually an indicator indicating a problem with your brake pads.
The old, worn rubber pads could be the culprit.
The old pads tend to harden and cause a lot of tiny vibrations, resulting in squeaking sounds.
Replacing the brake pads is usually the best practice.
Sometimes they can squeak if the brakes don\'t come in contact properly and may need to be repositioned to better align with the rim.
Try to squeeze the brakes when the bike is still.
Is the pad in full contact with the rim?
Is part of the pad in contact with the other part?
Keep in mind that some rims creak when they are wet, and there is nothing you can do about it other than replace the wheel itself.
Problem: My brake is stuck when I squeeze the lever.
Reason: nine out of ten times are caused by the sticking, bending or damage of the brake cable or cable housing.
The brake caliper itself may have problems in rare cases, but it is usually a cable problem.
The cable is glued to the housing when it is bent.
If so, I highly recommend that you buy a new cable and replace it from your local bike store.
Sometimes, adding a little bit of lubrication to the cable itself can make it stop pasting.
Keep the cable in the air, add a little lubricant to the top and let it go through the housing and extend down the length.
This is a good way to prevent rust from accumulating.
Problem: I really have to squeeze the brake Rod hard and the brake Rod won\'t stop either.
Reason: bike cables tend to stretch over time, so your braking system becomes less effective once the brakes are tight.
A simple bike brake adjustment can help simply tighten the cable.
Keep in mind that the effectiveness of the bike brake is based on cable tension.
You can take advantage of the built-in features of the bikein micro-adjustors (
Or barrel regulator)
Gradually increase cable tension without using any tools.
If this is not enough to tighten them, you need to loosen the nut at the end of the brake cable, pull a little forward and tighten the nut again (
This can be tricky if you \'ve never done it before, you may need someone to hold the cable for you).
Don\'t over tighten the cable, otherwise the brake pads will rub the rim and let you slow down!
Simple bicycle brake adjustment almost anyone can do some simple bicycle brake adjustment with the least amount of tools.
Barrel regulator: barrel regulator also known as micro regulator
The regulator is an easy way to increase the tension of the brake cable in a small amount.
They can be found on new and old bikes and are the easiest way to improve brake efficiency, especially when your cable is stretched.
Barrel regulators can be found on most bicycles.
They are usually located near the brakes themselves or on the handlebars.
All brakes that use cables can use barrel regulators, including disc brakes.
On most bikes, you can adjust the brakes by turning the barrel regulator clockwise. As you (slowly)
Turn and pay attention to your brakes.
If it is a linear pull (V-brake)
You should see the mat gradually approaching the edge.
If you have a mechanical disc brake, you will see the brake pads inside the brake closer to the disc brake when you tighten it.
You have to be careful that they don\'t rub on the disc.
I strongly recommend that you try this method before posting any tool, as it is usually the easiest solution, and you can adjust it at any time if you are not satisfied with the result.
Bicycle brake pad adjustment: in many cases, you can easily adjust the brake pads of your bike using simple tools.
Super normal v-brake (linear pull)
It is the easiest to adjust.
The pad is connected with a simple nut.
Loosen the nut and move the brake pads to the position you want.
Tighten it slowly and make sure the mat stays where you want it. V-
The brake pads are designed to be repositioned, so you can align them with the rims.
Professional tip: you can \"toe\" your mat if you want more stop power.
This means that you position it so that the front of the pad touches first.
While your mat will wear out faster, this can increase your parking power and reduce creaking. U-
Brakes, especially those with cheaper quality, will not be adjustable as before.
You can\'t completely relocate the pads either, although you should be able to align them with the curves on the edges.
The adjustment of disc brakes is completely different.
More about this.
Cable lubrication: When most people think of bicycle lubricating oil, they think of bicycle chains.
However, a simple bike brake adjustment is in your favor by using a lubricant.
The common cause of braking problems is that the cable is stuck.
There are two reasons for this.
I. Possible wear and tear of cables (
Bend, rust, wear).
Replacement is required.
Second, the cable may just cause too much friction inside the cable housing.
What I want to emphasize is that cable lubrication is a quick solution.
It doesn\'t actually \"fix\" anything.
Usually stickiness needs to be replaced as a case or cable for a long-term solution.
To lubricate the stuck brake cable, simply apply the lubricant to the top of the cable and the rest is done by gravity.
The easiest way is to unlock the brake cable on the lever, lift it higher to enhance gravity and apply the lubricant.
Then hook it back into place and squeeze the brake lever several times.
You can also apply the lubricant wherever you suspect it sticks to the cable.
It\'s just that the brake pads themselves don\'t have anything!
How to adjust the hydraulic disc brake?
There is a hydraulic brake on the bike, which is great.
There is no real competition in stopping power.
That is to say, they need more maintenance compared to traditional systems, and learning how to adjust the bike brakes that use cables doesn\'t help much with the hydraulic system.
With the hydraulic system, you need to learn how to discharge the braking device correctly, as well as PAD face adjustment, rotor shaping and alignment.
I may write another article on it, but if you are not familiar with these concepts, I strongly recommend that you have your local bike store do the job.
The adjustment of mechanical disc brakes on bicycle mechanical disc brakes has become very common, especially on mountain bikes with lower prices.
Overall, I don\'t believe that the mechanical disc brakes are better than the traditional linear traction method, but they do have some advantages, including better performance in dirt and mud.
Adjusting the mechanical disc bike brake system is not much different from the traditional way, but I should point out some key differences.
Cable tension is the key: First of all, keep in mind that disc brakes work the same way as other types of brakes: cable tension results in a good response.
Like conventional brakes, most mechanical disc brakes will have barrel/micro regulators and I would recommend using them first if the brakes are not responsive.
Tighten the pad: The disc brake stops by clamping the two pads on the vertical disc (rotor)
Connected to the wheel.
The shorter the distance the pad must travel, the more responsive your brake lever will be.
Please pay attention to the pads when you use the barrel regulator/manually tighten the cable.
Ideally, you want them to be about a metre away from the surface of the rotor on both sides.
Rotate the wheel to make sure it does not rub the plate at any time.
On some models, you can push the pad slightly by turning the bolts on the side of the manual regulator or clamp.
Sometimes you need to loosen the lock bolt in order to do this.
I do not recommend repositioning the pads unless absolutely necessary;
They should be set up correctly when the bike is built.
Adjusting the disc: adjusting the bike brake using the disc system usually requires some disc bending, especially on cheap/Department brand bikes.
If you notice that the rotor is friction welded at some point in rotation, but there is no friction plate at other points, you may need to use the disc brake rotor trimming tool to adjust it gently (bend)
The rotor restored shape.
Worn pads: like straight-line pull and U-shape
Over time, the brake pads on the mechanical disc brakes tend to wear out.
There are many different systems and the replacement is different, but many of them are magnetic and all you need to do is remove the wheel and pull the label to release the pads.
Do not squeeze the brake when the brake pads are off or the wheels are off.
The internal piston is usually from
Align, it will mess up your brakes!
If your wheels will be out of the bike for a while, I would recommend putting a piece of cardboard in the calipers in case anyone decides to squeeze the brakes!
Clamp alignment: you may need to align the clamp, especially when the rotor is squeezed with the liner on both sides.
There are two allen key bolts at the rear of most disc brakes.
You can loosen these bolts and the whole unit will slide from one side to the other.
Pull left or right until the rotor is aligned well in the center and tighten slowly again.
