Bike repair - How to Loosen the brakes ?
Before you can even think about fixing a flat or addressing any other tire or tube issue, you need to be able to remove the wheel from the bicycle frame. Fortunately, bike manufacturers have made the lives of bike riders easier by introducing things such as quick-release hubs and brakes.
Because brakes are typically designed to sit close to the wheel rim, their location normally prevents the wheel from being removed if the tire is fully inflated. If you want to remove a wheel, you first have to open the brakes so there's room for the tire to fit through the brake pads.
Many bikes have a quick release built into the brake, which quickly enables the cable to slacken and the brakes to spread. The quick release may vary depending on what type of brakes your bike has:
- Cantilever brakes: If you have cantilever brakes, squeeze the brake arms together with one hand to create slack in the cable and, with the other hand, lift the loose end of the cable out of its pocket. Release the breaks and they'll pop open.
- V-brakes: If you have V-brakes, pinch together the top of the brake arms to loosen the cable. Pull the rubber boot back to expose the cable Carefully pull the cable out of the narrow slot in the cable holder, and release it to open the brakes
- Side-pull brakes: For side-pull brakes, look for a small lever on the caliper where the cable is attached. Pull the lever upward and release the brakes just enough to allow the wheel to pass. In some models, you have to look for a button on the lever and push it to release the tension on the brakes.
Worst case, if you can't release the brakes to allow the tire to past through the brakes, let the air out of the tire; this will give you the clearance needed.

MTB Disc Brakes – Hydraulic or mechanical type?
You'd like to change your braking system of your bike? You'd like to get a better performance on your brakes? So get MTB disc brakes to your bike. But be prepared to spend some money on your mtb disc brakes and the stuff that belongs to it.
There are two common types of mtb disc brakes, mechanical (cable-actuated) and hydraulic. Slight difference between these two types are relevant.
Here are the main differences:
Actuation: Both systems use brake levers to start the braking process. The mechanical disc brakes use brake levers to give the cable a tug. The cable forces the mtb brake pads against a surface, known as the rotor or disc. The hydraulic disc brakes use brake levers to compress a fluid that will move the pads against the rotor.
Weight: Fluid vs. Cable. The fluid will be heavier then the cable and so the hydraulic mtb disc brakes will weigh more. It's not very much but there is a difference. If you want to have the lightest brakes try to use V-brakes.
Performance: The hydraulic mtb disc brakes will perform better then the mechanical type. This is because the fluid reacts faster then a cable that is pulled. Also the cable can rip apart and you will lose all the braking power.
Price: Of course better performance will cost more. New hydraulic mountain bike disc brakes will be a shade higher in price as the mechanical mtb disc brakes.
