Braking

Braking is the one system on your motorcycle that your safety depends on directly, every single ride. It's also an area where precaution outweighs everything else: a brake that works badly isn't a discomfort to put off — it's a reason not to ride again until it's fixed. This category gathers braking symptoms to help you understand what's going on.

The signs to watch are varied: a lever that travels too far or goes spongy, a lever that's instead hard and difficult to press, a squeal or screech on contact, a pulsing felt in the lever with each wheel rotation, or a brake that stays clamped and overheats the wheel. Each points to a different cause, from worn pads to a seized caliper.

Some braking jobs remain doable with method — like replacing the pads — but only by strictly following the manual's torque values, threadlocker where specified, pumping the lever before riding and a low-speed test. Anything that opens the hydraulic circuit (bleeding, fluid change, caliper rebuild), on the other hand, lets air in and calls for a professional: it's never a job to improvise.

Before drawing conclusions, a few free visual checks already tell you a lot: the remaining pad thickness, the level and colour of the brake fluid in the reservoir, the surface condition of the discs, and any trace of moisture around the hoses or caliper. Old, dark fluid, pads at the end of their life or a scored disc explain a large share of lost braking power. Note too that the 'warped disc' sensation when braking most often comes from disc thickness variation caused by pad deposits, not necessarily a truly distorted disc.

One point many overlook: brake fluid is hygroscopic — it absorbs moisture from the air over time. Old, water-laden fluid boils sooner under braking heat and makes the lever spongy, especially downhill or after several hard stops. Replacing it is a periodic service to respect: check the interval in your manual. After fitting new pads, remember to bed them in too — a few progressive stops to lay an even layer of friction material on the disc — and never ride without first pumping the lever to a firm pressure.

Select the symptom that matches what you feel to start the diagnosis. It will guide you towards the most likely cause while reminding you, at every sensitive step, of the limits not to cross alone. And keep this rule in mind for anything brake-related: at the slightest doubt, stop and have it checked. This tool helps you understand — it doesn't replace a certified mechanic.

Frequently asked questions

  • My brake is spongy — what should I do?

    A spongy lever betrays air or old, moisture-laden fluid in the circuit. Bleeding and changing the fluid open the hydraulic circuit: that's a job for a professional. Don't ride until braking is firm again.

  • Can I change my brake pads myself?

    Yes, with method: follow the manual's torque values, threadlocker where specified, pump the lever to a firm pressure before riding, and do a low-speed test. When in doubt, hand it to a pro.

  • Why does my brake vibrate when braking?

    On a motorcycle this pulsing most often comes from uneven pad deposits on the disc (thickness variation) rather than a truly warped disc. Worn floating-disc buttons can also cause it.
