A dirty caliper pin keeps the pad rubbing on the disc; once cleaned, the pad pulls back freely (illustrative)
Brakes · Maintenance

Does cleaning brake caliper pins and pistons affect brake pad life?

Yes; dirty or rusted caliper pins and pistons directly shorten brake pad life.

A disc of uneven thickness pushes the brake pad and causes vibration at the lever (exaggerated illustration)
Brakes · Maintenance

Vibration when braking: is it the brake pads or the disc?

Vibration felt in the lever, handlebars or frame when braking usually comes from the disc, not from the brake pads themselves.

With combined braking, the rear brake also operates the front brake; ABS also prevents wheel lock-up (illustrative)
Brakes · Maintenance

Is brake pad replacement different on combined braking (CBS) and ABS systems?

The brake pad itself and the basic replacement steps are the same; the difference is the extra care needed for linked and electronic components.

Brake fluid absorbs moisture and darkens over time; it is a separate maintenance item from the brake pads (illustrative)
Brakes · Maintenance

Can you replace only the brake pads without changing the brake fluid?

Yes; changing the brake fluid is not required to replace the brake pads.

A spinning wave disc and caliper; brake pads in a compound suited to the disc
Brakes · Maintenance

Which brake pads should you use with a wave disc?

A wave disc does not need special brake pads; you use a pad in the compound the disc is suited for and in the code that fits your motorcycle.

Brake heat rising lap after lap on the track; Brenta Ceramic Racing for the track (illustrative)
Brakes · Brenta

What are the best brake pads for the track and high-speed riding (track days)?

During break-in, the contact area between the new pad and the disc grows (illustrative)
Brakes · Maintenance

How do you break in (bed in) motorcycle brake pads?

Break-in seats the surface of new brake pads against the disc and lets them lay down a thin, even layer of pad material on it; it is done by braking progressively over the first 100–200 km.

Brakes · Maintenance

How do you replace motorcycle front and rear brake pads?

Replacing brake pads means removing the pad pin or the caliper, cleaning the caliper and pushing the pistons back evenly, fitting the new pads in the same layout as the old ones, tightening the bolts to the torque in the service manual…

Organic vs sintered pads compared on heat, wet surfaces, disc wear, noise and service life (illustrative)
Brakes · Brenta

Sintered or organic? A motorcycle brake pad comparison

Choose organic pads for light motorcycles, scooters and city riding; choose sintered pads for heavy or fast motorcycles, riding with a passenger or load, hills and frequent rain.

Metal fibers in a semi-metallic pad, fine grains in a ceramic pad (illustrative)
Brakes · Maintenance

What is the difference between semi-metallic and ceramic brake pads?

Semi-metallic pads resist heat and grip strongly, but they are noisier, produce more dust and wear the disc more; ceramic pads are quiet, low-dust and gentle on the disc, but more…

With a passenger and load, weight shifts to the rear and the rear brake works harder (illustrative)
Brakes · Maintenance

Why do rear brake pads wear out fast on motorcycles carrying a passenger or load?

On a motorcycle carrying a passenger or load, most of the weight sits on the rear wheel; because the rear brake can then transmit more force, it gets used more and the rear pads wear faster.

Gold, Black and Colored Chains: What Does the Coating Add?

The difference between gold, black or colored chains is the coating; it changes how the chain looks and adds extra rust protection, but it is not what determines the chain's strength.

How Are Track and Racing Chains Different?

Racing chains are designed for minimum friction and low weight; that is why they are made with very thin seals or no seals and are developed for racing conditions.

Chain · RK

What Is Chain Tensile Strength? kN and kg Equivalents

Tensile strength is the force at which a chain breaks when pulled from both ends; it is usually given in kilonewtons (kN), pounds (lbs) or kilograms of force (kgf).
