How to adjust the brakes on a bicycle? The rear brakes on a bicycle

If hydraulic brakes on your bike are set for a long time and started to work less, then it is time to adjust them. To begin, place the disc on the wheel hub, it is necessary that all the bolts are tightened evenly and thoroughly.

Ottsentrovyvaem caliper with respect to the

We now move on to the main point: how to adjust the brakes on a bicycle for the first time? We need to drive smoothly housed in the caliper. To achieve this, between it and the frame set goals. They come in different thicknesses, so setting method selection occurs. This is a lengthy process, because when tightening bolts caliper much more pressed against the frame, than if you just squeeze his hand. Substituting the puck constantly need to firmly tighten and watch located caliper relative to the disk.

However, hydraulic brakes on your bike are regulated much easier. For this purpose there adapery, which are located between the rear triangle of the frame and caliper.

You must first tie the adapter and caliper to it already. However, until the bolts should not be delayed, they should just fix everything. Then you need to hold down the brake lever and watch as the pads zazhmut drive. When he will press, caliper will be on their workplace.

For greater reliability should podorgat little wheel to everything fully into place and tighten the bolts. When everything is recorded, you need to bleed the brakes. This is done by pressing the sharp handle 15-30 times. This is done to pad steel in an ideal position for braking.

When nezazhatyh brake pad friction occurs the

It so happens that everything seems to be regulated, perfectly set, and when checking shifts slightly, then pads hurt drive. How to adjust the brakes on a bicycle in that case? Determine which of the pad rubs. Thereafter we relax the bolts on the adapter and displace it in the direction of rubbing. Also looking to become a block in parallel with the rotor. And so by selecting achieve perfect results.

When and left and right pads cling disk, you need to configure the hexagon of the brake lever. It must twist up until the pads are not arise, as it should. He is for this adjustment is intended. After all the settings necessary to check again how everything works

If the disc is bent

In the case of the disk curvature of how to adjust the brakes on a bicycle? It is necessary to align. Doing this can be a special tool, and you can use an adjustable wrench. It is necessary to determine the curvature of the zone and in the middle part of it to install an adjustable wrench, previously placing a piece of cloth to avoid scratching the surface. After that - a bend in the desired direction.

If the pistons push the pads unevenly

If one piston does not work freely, he is likely to be clogged. In this case it is necessary to remove a wheel, and then removed from the caliper pads. You will need a clean metal plate which has holes for fastening pins.

Using it, move the defective piston and press the brake lever so that he could get out clogged. Thereafter, it should be wiped with a clean cloth and put on its surface a mineral oil (non-aggressive to rubber). Then return the piston back, wiping excess oil. Increasingly polluted rear brakes on a bicycle, probably due to the fact that there there are more mechanical parts and drive.

When the pistons can not return to its original position?

Pistons can not be returned due to clogging, then you need to make the procedure as described above. Case may be, and the brake handle in it can also be dirty. Then it will need to be disassembled and cleaned. More serious problem - this is where the oil is leaking brake system. If the leak is not strong, it is necessary to change the gaskets in the joints. In the case of more complicated breakdowns may have to replace the brakes.

It so happens that the brake handle fails. This can occur when air is trapped inside the hydraulic line. Fix it helps pumping the brakes. However, this may be due to the breakdown in the hydraulic system. Depending on the place of course you need to replace the gasket, the worst option - replacing the hydraulic lines.

If you need to change the brake

Now consider what to do when my brakes for bicycles. To put them, the hose must be disconnected, because it needs to be pulled through fixing. If the hose is attached to the frame, you can not disconnect.

We will look at a more complex version, and will know exactly what to do in this case. Disconnect the hose and prodenem it through the strap. But before all this is done, you need to remove shoes, so they stay clean. After all, work with dirty oil, and can accidentally stain the pads and the disc.

Disconnect the hydraulic hose and see the cam, which is inserted into it, and compression fitting (it looks like a ring, put on the top). The cam is designed to ensure that when strong heating system to prevent the reduction of the plastic hose. A fitting holds it in place. To stretch the hose, it is necessary to cut off the end with the cam and the fitting. The cut must be clean and smooth. It is better to use a special cutter, with which you can quickly and efficiently carry out everything. If this tool is not present, you can use a blade or a knife and cut gently on a flat surface.

Putting the whole system

Connect shlangochku, she is thrust into the caliper, and it is necessary to leave a gap of about a centimeter. Ready, you can put olive and compression fitting. Shlangochku first to put on the nut, after - a clip. When worn, is inserted into the hose fitting. Him to sit safely, it is necessary to drive. Hose for this we press and trying to drive him fitting. Done. Now fix a nut, but it is worth remembering, if much of its clamp, the brakes will not work, so you should be very careful with this.

We have fully explored the question of how to adjust the brakes on any type of bike. Applying this knowledge in practice, you can easily troubleshoot any problems with hydraulic brakes.
