Take a look into the caliper and check your piston and the pad. Strictly speaking, the pads are made of two bits: a metal backing and the pad material. Sandwiched between the two pads is the metal spring that pushes the pads back out. Look how much of the pad material is left and start your brake pad maintenance.
Brake pads should be the correct material for the braking surface (not usually an issue unless you have carbon rims.) The pad needs to be free from excessive wear and free from grit and dirt as this will impede braking and damage the braking surface.maintain the brake pad
Firstly, the wearing of the brake pad is from daily cycling and improper position of the pads, like the brake, works unevenly and the pads hit the rim. Therefore, here are some tips of the adjustment of the pads to secure the pads in a right position.
Loosen the bolt that fixes the brakes on the frame and manually pivot the brakes so that the pads are about evenly spaced away from the rim. So it’s roughly centered and then you need to hold the whole brake mechanism and tighten the mounting bolt again. Now test the brakes and hopefully, the pads would be hitting the rim more evenly. Then adjust the gap between the pad and the rim and make sure there is a slight edge on the back and contact in the front will help reduce the squeal.
Secondly, brake less and brake softly. I’m not saying you should actively avoid braking when necessary - this would be dangerous - but you have plenty of opportunities to minimize it. Leave more space in front, giving you more room to make decisions in and more time for traffic conditions to change to your advantage (e.g. the queue to move maintain the brake padforward). In addition, you should brake more softly compared to quickly hit the brakes hard. When you hit your brakes hard it can wear down your pads.
Thirdly, you should keep your hand off the brake lever until you need to use the brakes. Pressing the lever can partially activate the brakes, causing you to overuse the brakes and wear the pads prematurely. It is always better to not get into situations where you have to brake hard. Planning and scanning ahead to allow yourself to slow down gradually.
Brakes are a wear item. You don’t work to maximize the life of your toothbrush, your toothbrush works to maximize the life of your teeth. And you replace it periodically, just like you buy more toothpaste. Brakes are exactly the same. Well engineered brakes wear the rotors and pads at the same rate, and when “they’re done”, they’re really done, and you need to replace both typically on all four corners.
Brake pads play a pivotal part in the cycling performance of the bicycle. It is connected to your cycling safety so much that you should maintain the brakes well in daily cycling and I hope the tips aforementioned can be a good help for you.
