Changing Bike Brake Pads: A Complete Guide

Changing your bike’s brake pads is like giving your bike a fresh pair of shoes! It’s all about stopping confidently, whether zipping through the city or tearing down a mountain track. So, let’s crack on and get those brakes sorted, shall we?

Have you ever noticed your braking performance wane a bit? It could be your pads wearing thin. Don’t fret! I’ll guide you through changing those pads so you can stop on a sixpence again.

First, check what pads your bike uses—disc or rim. Also, are they top-loading or bottom-loading into the calliper? Top-loading pads are a breeze to switch out, as they slide easily. Bottom-loading might need more elbow grease, but it’s no hill for a climber!

Tools Needed

Changing your bike’s brake pads is straightforward, but you’ll need the right tools to do the job efficiently. Grabbing the proper kit makes the process smoother and ensures the safety of your future rides.

Here’s what you’ll need:

  • New Brake Pads: It’s essential to get the correct type of pads for your bike, whether for rim brakes or disc brakes.
  • Allen Keys/Multi-tool: These are used to loosen the calliper arm and adjust the retaining screws that hold the pads in place.
  • Tyre Levers: Necessary for prising the wheel free from the frame, especially if the tyre fits tightly.
  • Pliers (preferably needle-nose): Handy for pulling out the retaining or split pin that secures the pad.

Each tool has its unique role. Allen keys ensure you can loosen and tighten the various bolts effectively. The pliers are perfect for the fiddly bits, like the split pin or retaining pin – these little metal pieces can be challenging to handle without the right tool.

If you want to purchase these tools, your local bike shop is a good start, or check out online retailers for a convenient option. For the DIY enthusiasts, you’ve got your eye on a complete bike maintenance kit. It’s an investment that keeps on giving!

Remember, mountain bikes, road bikes, and hybrids might have different brake systems, so always double-check you’ve got the specific pads for your setup. And hey, take a moment to admire that shiny new brake pad’s surface – it’s the key to maintaining your braking performance, so treat it carefully!

Step-by-Step Guide

Step 1: Remove the wheel

First things first, let’s get that wheel off! Flip it open and loosen the wheel if you’re rocking a quick-release lever. For a thru-axle, unscrew and pull it out. Give the wheel a gentle tug; it should come right off, revealing the brake calliper.

Step 2: Remove the brake caliper

Now to the brake calliper – your mission control for the pads. Some models have a retaining screw or a split pin; you’ll need needle-nose pliers for the pin or an Allen key for the screw. Carefully extract the holding mechanism and slide the old pads out. Remember, if the pads are asymmetrical, note their orientation.

Step 3: Retract the pistons

Before you install the new pads, let’s put those pistons back in their place. Do you have a plastic tyre lever? It’s suitable—use it to gently push the pistons back into the calliper. Metal tools are a no-go here; they can damage your pistons.

Step 4: Install the new brake pads

Place the new pads snug against the spring, ensuring they’re correctly oriented. Then, guide them into the calliper, lining them up so the retaining mechanism fits back in without a fuss.

Step 5: Secure the new brake pads

If you’ve got a split pin, bend it into place so it’s secured. For a bolt, thread it through and tighten it up. Is there a pin at the end? Clip that into the groove on the bolt to lock everything down.

Step 6: Reattach the calliper and wheel

Nearly there! Slide the calliper back over the disc brake rotor, securing it in place. Then, pop the wheel back in, ensuring it’s seated properly. For quick-release, tighten and close the lever; for a thru-axle, screw it in and tighten.

Tips & Reminders:

  • Don’t touch the brake lever while the wheel is out – you might accidentally push the pistons too far.
  • Brake pads differ; ensure you’re using the right type for your bike and that the wear indicators are considered. If vertical slotted lines exist, the pads should face the braking surface direction.
  • When everything’s assembled, squeeze the brake lever – the pad should touch the rotor without rubbing.

Changing your brake pads boosts your braking performance and makes your rides safer. Plus, it feels excellent to DIY, right? Always check for wear indicators and ensure you’re using bike-specific pads for your road or mountain bike to get the best results. Keep it smooth, folks!

Have you ever wondered how to switch out your bike’s worn disc brake pads? It’s not just about saving a few quid; it’s about taking pride in some DIY bike maintenance. Here’s a quick hit list to avoid those rookie mistakes and keep your brakes in tip-top shape.

Best Practices:

  • Pair Replacement: Always swap pads out in pairs to maintain even braking performance.
  • Caliper Care: When loosening the mounting bolts of the calliper, use the right-sized hex wrench. No rounded bolts, please!
  • Pad Alignment: Ensure new pads are correctly aligned; they should not touch the rotor when the brake lever is released.
  • Torque Settings: Tighten bolts to the manufacturer’s specified torque. This is crucial for the calliper and mounting bolts.

Maintenance Tips:

  • Pad Inspection: Regularly check pad wear. Most brake pads have wear indicators; if they’re flush with the rest of the pad, it’s time for a change.
  • Clean Rotors: Keep the disc brake rotor free of oil and grime; a clean rotor improves pad life.
  • Adjustment: Post-install, spin the wheel to check for rubbing and adjust accordingly. A little tweak can make all the difference.

Common Mistakes:

  • Wrong Pads: Not all pads fit all bikes. Road bike brake pads differ from mountain biking pads—grab the right ones.
  • Over-tightening: Avoid Hulk-smashing the bolts. It’s about finesse, not brute force.


  • Check out detailed tutorials or forums specific to your bike model.
  • Video guides can be a visual aid to what you’ve just read.
  • Manufacturer manuals are a treasure trove of bike-specific info—give them a look!

Remember, there’s no shame in getting a little help from a local bike shop if things go pear-shaped! Keep these tips in your back pocket, and you’ll be the DIY king of the cycle lane in no time.


Are you wondering about the perks of changing bike disc brakes by yourself? It’s not just about saving a few quid; it’s also about enhancing your bike’s stopping power. Here’s a quick rundown:

  • DIY Benefits: You gain hands-on knowledge of the workings of bike disc brakes, ensuring that you’re prepared to sort out issues should they arise during a ride. Plus, you can brag to your mates about your new-found mechanical prowess!
  • Safety First: New pads improve braking performance, making your rides safer, particularly for those adrenaline-fueled descents on your mountain bike or zipping through traffic on your bike.
  • Performance: Swapping in new brake pads can restore that satisfying feel of responsive brakes, giving you precise control over your speed and handling.

Here’s what you’ll need:

  • A set of new brake pads specific to your bike’s disc brakes
  • Appropriate tools like Allen keys or hex wrenches
  • Maybe a piston press or a flat-head screwdriver for pushing back the pistons

Steps at a Glance:

  1. Open the quick-release lever or remove the wheel’s thru-axle to access the brake calliper.
  2. Use the Allen keys or hex wrench to undo the mounting bolt and remove the old brake pads, taking care not to lose the retaining screw or split pin.
  3. If there’s a wear indicator, check against your new pads to confirm it’s time for a change.
  4. Fit the new pads in, ensuring they’re snug against the metal backing of the brake shoe.
  5. Reassemble everything and give the brake lever a few squeezes to seat the pads correctly.
