Do not take your Bike to Kyle's Bike Shop they handled my bike so poorly they can not work on Vintage Schwinn' and the attitude they had if it wasn't a high dollar bike don't expect good service. I had to find my own parts, had to take the bike back twice to get the wheel trued and they ruined my bike it is so scrapped up the Schwinn is gone on the side of the bike. If you care about your bike do not take it here.
Brakes come in a variety of designs depending on the age and style of your bike. Rim brakes offer more modulation but have less stopping power, so are more suited to riding on the roads. Disc brakes can provide huge amounts of stopping power so are best suited to off road riding, although ‘V’ rim brakes are also well suited to mountain biking. All brakes use a friction system to stop the movement of the wheel, so regular checks of the contact pads should form part of your regular cycle maintenance.
