Hydraulic bike brakes are great for stopping power, but they do require some maintenance. The most common issue with hydraulic brakes is worn brake pads. When the brake pads get too thin, they can start to squeal or even grind against the rotor.
This not only affects your braking performance, but it can also damage your rotors. Replacing your brake pads is a pretty simple process that anyone can do at home with just a few tools.
- Remove the wheel from the bike
- Unscrew the bolts that hold the brake pads in place
- Pull out the old brake pads and insert new ones
- Screw the bolts back in place to secure the new pads
- Reattach the wheel to the bike and test your brakes before riding again

How Do You Replace Hydraulic Brake Pads on a Bike?
Assuming you are talking about a bicycle with hydraulic disc brakes, the process is as follows:
1. Remove the wheel from the bike and place it on a work surface. If your bike has quick release hubs, you can simply undo the skewer and pull the wheel out.
Otherwise, you will need to remove the axle nuts or bolts holding the wheel in place.
2. Locate the brake pads. On most hydraulic brakes, there will be a cover over the top of the pads that needs to be removed in order to access them.
Once this cover is off, you should see two brake pads sandwiched around a metal rotor. One pad will be mounted to a fixed caliper arm, while the other pad is mounted to a movable caliper arm via a spring.
3. Unscrew and remove the retaining pin or clip that holds the movable pad in place (this may vary depending on your brake model).
With this pin removed, you should be able to push or pull out the old brake pad from its sleeve in the caliper arm. Repeat for the other side/pad.
4a) If your new pads come pre-installed with backing plates (the metal plate that provides structural support forthe pad), simply line up each backing plate with its respective caliper sleeve and slide it in until it clicks into place.
Make sure that each plate is properly seated before proceeding to step 4b).
4b) If your new pads do not come with backing plates, start by inserting one end of each new pad into its respective sleeve in the caliper arms, making sure that they are oriented correctly (the curved edge ofthe pad should face outward). Use a small amount of grease or lubricant on both sides of each newpad if desired – this will help reduce noise and improve performance over time.
Once both ends are insertedinto their sleeves, use your fingers or pliersto slowly squeeze each pad until it slides allthe way into place so that there is an equalamount ofpad material protruding fromeach side ofthe calipers arms..Make surethat eachnewpadisproperlyseatedbefore moving onto step 5.. .

How Do You Remove Shimano Hydraulic Brake Pads?
Shimano hydraulic brake pads can be removed by depressing the piston with a syringe or similar device and then unscrewing the pad retaining screws. The caliper must then be pried open to remove the old pads and insert new ones.
How Often Should You Change Hydraulic Brake Fluid on a Bike?
How often you should change your hydraulic bike brake fluid depends on a few factors. One is how much you ride your bike. If you ride regularly and in all types of weather, you’ll need to change it more frequently than someone who only rides occasionally.
Another factor is the type of fluid you use. Some fluids are designed to last longer than others. Finally, if you notice any problems with your brakes, such as reduced stopping power or leaking fluid, that’s an indication that it’s time for a change.
In general, it’s best to change your hydraulic bike brake fluid every six months to a year. This will ensure that your brakes are always performing at their best.
Do You Need to Bleed Hydraulic Bike Brakes?
No, you don’t need to bleed hydraulic bike brakes. However, if your brakes feel spongy or unresponsive, bleeding them may help. To bleed your brakes, you’ll need a syringe or bleeder kit, fresh brake fluid, and an assistant.
Once you have everything ready, follow these steps:
1. Position the syringe or bleeder kit on the brake’s bleeder screw.
2. Have your assistant pump the brake lever until it feels firm.
As they’re doing this, open the bleeder screw so that brake fluid can flow out into the catch jar. You may need to do this several times before fresh fluid starts flowing out of the bleeder screw – this is normal.
3. Once fresh fluid starts flowing out of the bleeder screw, close it and have your assistant keep pumping the brake lever until it feels firm again.
Repeat this process until there are no more air bubbles in the Brake line (you’ll be able to see them in the catch jar).
How to Replace Bicycle Disc Brake Pads
How to Change Brake Pads Bike
If your bike has disc brakes, then you will need to change your brake pads from time to time. Here is a step-by-step guide on how to do this:
1. Start by removing the wheel from your bike.
You will need a wrench to loosen the bolts that hold the wheel in place.
2. Once the wheel is removed, take a look at the brake caliper. You will see two brake pads inside of it – one on each side.
3. Use a Allen key to remove the retaining pin that holds the brake pad in place (this will be different depending on what type of bike you have).
4. With the retaining pin removed, you can now pull out the old brake pad and replace it with a new one. Make sure that the new pad is positioned correctly before replacing the retaining pin!
5. Repeat this process for the other brake pad, then re-attach your wheel and go for a test ride!
Conclusion
If your bike has hydraulic brakes, you’ll need to change the brake pads every so often. Here’s a quick guide on how to do it. First, remove the wheel and then unscrew the retaining pin that holds the brake pad in place.
Next, pull out the old brake pad and insert the new one. Make sure that the new pad is lined up correctly before screwing the retaining pin back in place. Finally, reattach the wheel and you’re good to go!
