Check and adjust the bike disc brake

Your bike brake plays a very important role for your bike. To achieve good performance, the brakes must always be clean and in smooth operation, properly adjusted before each ride.

When you first bought a car the brake worked very smoothly but after going for a while, going through many trails, bicycle disc brake usually some loss of braking efficiency is lost. . This is also what results in your braking longer, less efficient and less controllable. A disc brake uses clamps that are attached to the forks at the front and rear. The rotor blades are mounted on the wheels. When you squeeze the brake lever, the screw cable’s inner brake press gently presses the disc to slow down the wheel.Most modern mountain bikes come equipped with disc brakes. Road machines also use this brake.

Note: Maintenance of a basic brake system includes ensuring that the brakes are quickly in place and operating at their best.

1. How often do you check bicycle disc brakes?

Structure of disc brakes

A master check is performed before each inspection. Make sure the brake components are properly positioned and able to perform better. job so that problems can be detected and fixed in time. Ride your bike more often to spot brake damage early.

2. How do I check and adjust the brake?

-Couple brake

Brake assemblies include brake discs and brake pads. These assemblies may, when assembled, be installed incorrectly or break or fall out of their proper position due to circumstances such as an accident. They should be checked to make sure all parts of the part move freely and are in place, all bolts are very quiet.

-How to test the brake set

In order to be able to check the position of the brake assembly, perform a visual inspection on both the front and rear of the clamp, making sure that the rotors are always between the brake pads. Each side of the brake pads will make full contact with the rotor when the brake is applied.

-How to fix the brake assembly

The brakes are not centrally positioned or misaligned, causing one side of the brake pad to contact the front rotor of the other, resulting in low resistance and low noise. The readjustment in many cases is to loosen the bolts and be able to move the brake pads slightly from side to side to position it properly.

In addition, to be able to check and ensure the bolts on the rotor discs and brake pads are in place. Some require you to add or remove brake pads from the rotor.

3. Check and adjust details

3.1 Brake pads

When the disc brake is in use, the gasket will wear over time. This can result in slower brake response times and requires a lot of effort from you to be able to brake.

Disc brake pads

Observe whether the wedge plate is significantly scratched or worn. Perform a gasket test by removing the wheel and looking at the space in which the rotor rotates. If the pads are enameled, remove them immediately and release them gently on sandpaper on a flat surface. If the spacer is less than 3 mm thick, the metal bracket should be replaced immediately.

Touching the disc or rotor brake often causes the brakes to deteriorate. Grease on the brake can damage the brake with even the smallest amount of oil, even from the skin of the hand. Hence whenever you handle them, try to minimize the brake surface’s contact with your bare skin. If you touch, use pads or clean them with a special product to clean the brake discs.

3.2 Brake Discs

Check the rotor blades for dirt, dust and debris. Check that the rotors are always flat without rubbing against the brake pads. If the rotor is especially dirty clean them with alcohol and continue with sandpaper.

While cleaning, observe the rotor blades to make sure that the bolts mounted on the surface are always in the correct position, to avoid dropping and rubbing causing noise when braking.

3.3 Braking

Brake lever system

Your brake levers can become contaminated with dirt and mud over time. They can also slip out of place on your steering wheel. If you have hydraulic disc brakes, immediately look for signs of leaking fluid near the lever system.

To check them the only way is to squeeze the brake. The most suitable position is the distance between the brake lever and the hand is 1 inch, your brake should be firmly held even when tilting. Check each lever separately by pushing it up, down and horizontally and they should move smoothly when squeezed without jerking or making noises.

One note with hydraulic disc brakes is that you should never tighten your brake lever when the wheel is removed from the frame or fork. Doing so will result in the brake pads being clamped and difficult to separate.?

If you find that your leverage doesn’t work when it needs to, there are a few steps you can take.

LHow can the brake lever be fixed?

Clean and lubricate levers. If you are experiencing poor braking, cleaning or repairing is required. Try applying a very small amount of lubricating oil to the shaft areas, while forcing the levers to close.

If you have mechanical disc brakes you should wipe them gently along with lubricating your brake cables every month or whenever there are visible signs of rust on the surface. Lubricate by inserting a small amount of dedicated oil into the cable carefully according to the instructions without placing it on your brake pads or rotor.

If you have hydraulic disc brakes or levers that feel there may be air, remove the air by pricking the brake. The brake injection is a procedure that purifies hydraulic hoses from any air bubbles. Look to a bicycle store to help you with this.

Reposition your brakes: If you have the mechanical disc brake, your brake pads may be away from the rotor. Before repositioning, make sure the gasket is not worn out too much. If the gasket is less than 3 mm thick, including the metal bracket, needs to be replaced. If the brake pad is okay, turn the adjustment buttons on the cable to re-position the gasket with the rotor. The proper distance between the rotor and the brake pad depends on the type of brake you have. So please refer to the instruction manuals included with your brake.

On a side note are hydraulic disc brakes with self-adjusting brake pads to ensure that the correct lever can be pulled so that there is no turning rotation on hydraulic cutters.

3.4 Brake hose, cables and covers

If you have hydraulic disc brake, check all hydraulic hoses and fittings for leaks. Leaks can sometimes be difficult to detect. However, this dirt tends to cause oil to leak, which is one of the signs to look out for. If you see a leaking ball, bring the bike to the repair shop.

Mechanical brake discs use the same cable and housing as the rim brake. The cable can also crack, rust or weaken over time, when this happens, the cable overlap can cause a slow brake squeeze response. In addition, the flexible cable sheath protects your brake cables against corrosion, cracking and clogging over time. The cable must be moved freely through all cable sheaths.

If you are someone who does not have much experience in work bicycle repair and maintenance or weak in mechanical knowledge, bring your car to the nearest repair shop to get the best help.
