How do I know when to swap my pads? Despite what you might have heard, the best way to check the pads is with a visual inspection. You should get used to doing this at least every few rides depending on the conditions. It's very much worth removing the wheels to familiarise yourself with what the different parts of the pad actually look like. With the wheels out, you can look into the caliper itself and you'll be able to see the round pistons which push the backing material of the pad. Closest to where the rotor will be you'll see the brake pad material itself. Commonly there will also be a helper spring which mounts above the pad and helps keep the brake pad against the piston and away from the rotor. Even if you're going to get a mechanics help with changing the pads you should know what you're looking at so you can make an informed decision about when your pads are worn out (or getting worn out). Don't wear the pad material down all the way - if this happens it can cause damage to the rotor and in extreme cases... 更多資訊 What Tools do I need to swap my pads? Most systems don't require specialist tools to do the job and commonly you'll be fine with a set of allen keys, a pad spreader and a bit of knowledge. It's always worth checking the official process recommended by the manufacturer of your brakes first. Most major brands publish this info on their website, via a technical website or via their own YouTube channels. Broadly most systems work in a similar fashion and essentially you'll need to reset the pistons which I normally do when the old pads are in place. I use a pad spreader (most tool companies make a relatively cheap spreader) to push the pads apart and reset the pistons. Then I remove the pads and clean everything, first with a wash and then with a specific disc brake cleaner. I also clean the rotors with the disk brake cleaner and a new clean rag. Then the new pads go in complete with the helper spring, pad bolt and any spring clips. Refit the wheel, visually check that the rotor is central in the caliper and then operate... 更多資訊
