How To Install Disc Brakes On A Motorcycle

A big part of owning a motorcycle is e'er making sure information technology'due south well maintained and road-worthy. For the rider, this ways checking up on little things similar the battery, bulbs, lubricants, and the tires. Other matters are normally all-time left to service centers or shops, as part of your preventive maintenance service. Yet with the community quarantine currently in place, you might not have that option right now.

For those of you with the correct tools and parts, many of these more complicated maintenance procedures — like changing brake pads, the concatenation or drive belt; batteries, and spark plugs — can be a exercise-it-yourself (DIY) affair.

Like most clay riders, I too exercise most of the maintenance work for my motorcycle mystelf. As some of you may know, riding off-road does some serious vesture and tear on the bike. As such, over the years, I've invested in tools and so that I don't demand to pay someone to work on my wheel as frequently. Non only will it save me time and money, but it is too reassuring to know that the job is done the way I want information technology to be.

We too encourage yous to read your motorbike's possessor's manual before doing whatever maintenance work on your bike, paying special attention to the maintenance intervals and how to'southward.

Though typically best left to shops or mechanics, brake pads (for disc brakes) are ane of the parts you tin actually install on your own. Replacing your bike's brake pads is actually pretty easy. In most cases, information technology merely requires the bones tools found in the factory toolkit of your motorbike. Before starting, brand sure yous accept a new set up of brake pads on hand.

We'll also cover cleaning your restriction system. It'southward fairly piece of cake to do, but experience free to skip that step if you don't ride off-road or you find information technology also complicated.

Similar what we e'er say: earlier starting whatever wheel piece of work, make clean your motorcycle first. We share tips on how to do it in this story: Motorcycle TLC that volition keep you busy during lockdown.

Parts of a brake

Whether with an Anti-lock Braking Arrangement (ABS) or without, the bones components of disc brakes are generally the same. The organization has 3 parts: the caliper, disc and the master cylinder.

Caliper

The brake caliper is the function that holds the brake pads and squeezes the disc when the rider applies pressure on the brake lever. Motorcycles are unremarkably fitted with floating calipers with just one piston. When the brake lever is squeezed, the piston pushes the pad towards the disc. Once this side makes contact with the disc, the other side (mounted on sliding pins) is also pulled toward the disc to bite the disc, creates friction, and slow downwardly the wheel'due south movement until the lever is released.

Disc

This is the shiny, circular metal surface continued to your motorcycle's wheel. The brake pads squeeze this surface to deadening down the bike.

Primary cylinder

This is a device that converts the forcefulness you lot apply on the restriction lever into hydraulic force per unit area. Brake fluid, stored in the reservoir, travels through brake lines towards the piston. Considering restriction fluid cannot be compressed, information technology pushes the piston, which in plow, causes the restriction pads to seize with teeth the disc and tedious down your motorcycle.

Now that you're familiar with the brake components and their function, let's start with the replacement of the brake pads. I'grand working on a Honda clay bike, but nearly all motorcycle disc brake systems work the same fashion.

ane. PREPARATION

Keep the cycle stable

You'll exist unscrewing some tight and tough parts so be certain your motorcycle is stable and won't move. Before starting your piece of work, place the cycle on a center stand or whatever sturdy motorcycle platform. This is to ensure that the bike is continuing direct. It's easier to piece of work on the bike this way.

Gather your tools. You'll exist needing wrenches. Nosotros recommend keeping a penetrating oil (like WD-40 or Mechanix 5) nearby.Pro tip:Y'all'll exist working with a lot of bolts and screws. They may exist screwed on tightly and difficult to remove. To avoid rounding these bolts, we highly recommend using a box, socket, or ratchet wrench instead of an open wrench. These crave much less effort.

If yous intend to do the cleaning part, y'all'll need an sometime toothbrush, steel wool, a basin to wash the parts in, and laundry detergent (preferably liquid). Finally, y'all'll need an old rago (trapo) to dry out the parts with.

Also accept gloves and protective eyewear handy as yous'll too be dealing with dust and brake fluid which may irritate the eyes and peel.

Keep a tray nearby. Put the screws and parts y'all remove here. Having a tray makes it easy to organize the parts and remember screw positions, making it easier to put them all dorsum together afterwards on.

2. REMOVAL

Remove the wheel (optional)

Though this step is optional and could mean extra labor, removing the wheel gives you a lot of room to work with. This will also give you a improve bending when inspecting your restriction caliper, disc, and brake pads for signs of harm before removing it. This extra pace is as well a bang-up opportunity to cheque your wheel bearings, which, under normal riding conditions, should final 30,000 to 40,000 kilometers from my experience on small bikes. On clay bikes, they usually need replacement sooner since, off-road riding exposes information technology to mud, sand, and even water. Regular exposure to these elements tin can wear information technology downward faster.

Spray penetrating oil

Since your cycle's brake calipers are exposed to a lot of mud and dirt brought nigh by daily riding, spray penetrating oil on the screws. Penetrating oil likewise acts as a cleanser, removing clay off them. This besides lubricates them, making removal of these easier.

Use the correct size of Allen wrench

Generally, the pin screw that holds the brake pads in place requires a hex central, Allen wrench or Torx for large bikes. Always make sure to use the right kind and size or you risk dissentious and rounding the caput of the screw, making information technology difficult to grip afterwards. If y'all're not sure of the size, examination fit and turn it lightly to brand certain information technology grips the screw caput. If it doesn't even encompass the spiral, it's too minor. If it slides a lot, it'south also big.

Pro tip: Before unscrewing, pay shut attention to where and how the retainer and jump pads are placed. These thin sheets of metal keep the brake pads in identify. These are important to go on rails of considering, later removing the pivot, the pads will autumn off. These parts may autumn off too.

^{Worn restriction pads like these, take very lilliputian material left to grip the disc.}

Past this fourth dimension, you'll have a skilful look at your brake pads. Worn brake pads (like in the film) accept very petty textile left to grip the disc. It's important to replace these before they completely vesture out to prevent metallic-to-metallic contact between it and the disc. The resulting damage can toll you more on repairs, possibly demand a rotor replacement, as well as existence unsafe for riding since the brakes are compromised.

three. CLEANING

Pump the brake to push out the piston

Every bit you have noticed by at present, your bike'due south restriction caliper may require some serious cleaning, including the piston. Dirt and grime can accumulate even on the piston subsequently years of riding. Putting in new, thicker restriction pads with a dingy piston could damage the oil seal of the caliper. Cleaning information technology will ensure smoother movement of the piston.

To simplify the piston'south removal, pump the restriction pedal (for the rear brake) or lever (for the front brake) to push out the piston. If yous're doing information technology right, it should wait like the photograph higher up.

Remove the caliper from the sub-assembly

This step is pretty straightforward. Remove all the bolts that adhere the caliper to the sub-assembly, including the fluid bolt connecting the caliper to the primary cylinder. Keep track of where each part goes for reassembly later.

Use protective goggles and gloves, if you have. Be extra conscientious when handling these parts. They may exist coated in restriction fluid. This is a toxic substance and may irritate your skin. Don't rub your eyes when handling these parts.

Clean the caliper

The proficient affair well-nigh cleaning the brake caliper is that information technology doesn't require a special cleaner or solution. All you lot need is an sometime toothbrush, steel wool, warm water and laundry detergent (preferably the liquid kind). For the caliper, start brushing from the inside, working your way out. It'due south done in this mode and then that dirt from the outside won't get inside the caliper.

Using the steel wool, generously scrub the piston until all the dirt and grime is removed. In some cases, grime may take settled for also long and may have already corroded the piston. If this is the case, consider replacing your brake caliper piston (through a repair kit) every bit it may compromise the brake organisation'south ability to do its job: stopping your motorcycle.

With small items like O-rings, bolts, and the servant springs, take extra intendance as these can bend and deform hands.

Rinse the parts with clean h2o. Dry all of the parts by wiping them on an old rag (trapo). Do not begin reassembly if they are wet or damp. If you have an air compressor and blower, you can utilise it to blow off excess water from the caliper.

4. REASSEMBLY

Reassemble the caliper

Even so call up how to put it all back together? Returning the caliper to the caliper sub-associates will be the same process in opposite club. Gather all the parts and brainstorm to reassemble the caliper. Start with the caliper.

Pro tip: Before re-installing the caliper piston, use your finger to put a generous amount of brake fluid onto the oil seals (like in the photo above). This not only ensures a perfect fit, just the restriction fluid will also act as a lubricant, making it easier to re-install the piston. Once done, push button the piston all the way in, until information technology flattens out and is level with the caliper's inner surface.

Before attaching the other one-half of the caliper (the side without a piston), put a niggling grease on the sliding pins like in the photograph higher up. The grease keeps h2o away and also ensures smooth movement of the floating brake caliper.

5. INSTALLATION

Install new brake pads

Make sure that the retainer and spring pads are placed in the correct manner. Re-install the new pads by putting the side closest to the piston first. And so insert the other pad.

Screw in the pin screw to lock the new brake pads in identify. Be extra conscientious not to over-tighten the screws. The rule of thumb is, just use one hand to tighten them. Use only the force of your wrist, nearly the same force you would use to tighten the cap of a canteen of soda. Pro tip: Similar what was suggested above, put a little grease on the pin screw before screwing information technology back in.

Job done!

At that place you have it! You have now done a DIY brake pad replacement and caliper cleaning. It might non exist as easy your starting time time, but doing it again will help you familiarize yourself with the process. Investing in some tools for this can also make the job easier. And if you're up for doing this kind of matter, it can salvage you a lot in terms of bike maintenance costs. These skills volition likewise come in handy in more than unpredictable situations, like during an out-of-town ride with your friends.

If you programme on doing more DIY maintenance, nosotros recommend stocking upwards on consumable parts similar brake pads even if yous don't need them yet. They'll come in handy if the parts break or wear downward sooner than you await. They're also perfect for the electric current situation, with much of the country on lockdown and there are no motorcycle shops open. With all the idle time, you could practice some bike maintenance.
